Oracle SQL Tutorial 33 - NUMBER Data Type
 
07:18
This video we are going to discuss the NUMBER data type. The Number data type is used to store integers, and real numbers. When you create a column as a NUMBER, you can store pretty huge or pretty small numbers in this column. Now there are two things you need to consider when working with numbers, and that is the precision as well as the how big the number is. For example, we can store the number 9.9. This has two significant digits. We could also store the number 9.9 X 10^4. In this situation, the number is much larger, but the number of significant digits is the same. 9.9 are the significant digits. When we expand this out we just have 99000, and the zeros are just used for size and are not considered "significant" in this situation. In fact, you get a max precision of 38, but a maximum value of 9.99 * 10^125. You can also use this data type to store very small numbers. Check the docs for the specifics on maximums and minimums. You can provide it with two pieces of information: Precision - The total number of digits. Scale - The number of digits to the right of the decimal. You do it in this format: NUMBER (precision, scale). The important thing to remember in this is that when you specify a precision, you will be limiting the max size of the numbers. The secret behind this data type is that it is actually stored in scientific notation. That is we store a number and then we can multiply it by 10 raised to some power. This allows us to store much larger numbers without taking up a ton of space. The oracle docs actually gives a formula that you can use to see how much storage is going to be required for a specific NUMBER data type. How much precision can be used? The acceptable range is 1-38. What about scale? The range is actually -84 to 127. I'll explain the scale in more detail in an upcoming video. That's because there is a lot of confusing things here…What does it mean for the scale to be negative? How can we have a scale that is bigger that the total number of digits available through the precision. That's a topic for another video. It's important to understand that when we increase our scale, we decrease the max size of the number. For example if we have a precision of 5 and a scale of 3, the highest number we can store is 99.999. This is in contrast to a precision of 5 and a scale of 2 which allows for up to 99.999. Either way you get 5 significant digits, but the numbers of digits to the left and right of the decimal change. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Session6 Data type in Oracle
 
15:25
Session 6: Datatypes In Oracle   ALPHABET           : A-Z , a-z NUMBER              : 0-9 (with precision and scale) DATE / Temporal  : any Date and time (Hours, Minutes, Seconds, Mili-seconds, Timestamp, Timezone etc)   Alphabet + Number = Alphanumeric Data                                     = String / CHARACTER Datatype Category Number                    =  Numeric Datatype Category Date                         = Date Datatype Category 1. CHARACTER Datatype: CHAR, VARCHAR, NCHAR: CHAR is fixed length datatype and VARCHAR is Variable length datatype to store character data. i.e. A-Z , a-z , 0-9 , all keyboard characters etc. The default size is 1 character and it can store maximum up to 2000 bytes. Example : EName, EmpID, PassportNo, SSN, etc. EName CHAR(10) := ‘TOM’; wastage of 7 space after the string EName VARCHAR(10) := ‘TOM’; Spaces can be Reuse which left after the string NCHAR additionally handles NLS(National Language Support). Oracle supports a reliable Unicode datatype through NCHAR , NVARCHAR2 , and NCLOB  VARCHAR2, NVARCHAR2: These are Variable length datatype. VARCHAR2 handles alphanumeric character string whereas NVARCHAR2 handles alphanumeric character string with NLS(National Language Support). The default size is 1 character and it can store maximum up to 4000 bytes.   LONG:  Variable length string.  (Maximum size: 2 GB - 1) Only one LONG column is allowed per table.

MySQL 31 - DECIMAL Data Type
 
02:20
The DECIMAL data type is similar to the INT data type in that when you use the number for math, it maintains precision. The difference though is obvious in the name. The DECIMAL data type allows for numbers after a decimal point (and before the decimal point). The DECIMAL data type allows us to store what is known as a fixed-point number. A fixed point number is a number that has a specific number of digits available to store numbers in. That means we can't do things like use a DECIMAL data type to store as many digits of PI as possible, because we can't store unlimited digits. We are limited to a certain number. There are two keywords you need to understand when you are working with the DECIMAL data type, precision and scale. Precision is the number of digits and scale is the number of those digits that will come after the radix. You are going to want to provide these numbers when you declare a column of this data type. For example, DECIMAL(5, 2) has a precision of 5 digits and a scale of 2 digits. That means we can store a maximum of two digits after the decimal and four digits total. This gives us a possible range from -999.99 to 999.99 The highest number of digits is 65, and the highest number of digits after the decimal is 30. This data type is also known as DEC, NUMERIC, and FIXED. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle CAST Function
 
03:23
https://www.databasestar.com/oracle-cast/ The Oracle CAST function allows you to convert one data type to another. It’s similar to the TO_NUMBER, TO_DATE, and TO_CHAR functions, but allows for more functionality, including converting to many other data types. The syntax of the CAST function is: CAST( {expr | MULTISET (subquery) } AS type_name ) The structure of this function is different to other functions, because it uses the word AS to separate parameters rather than a comma. You can run this function like many other functions, on a single row, which would look like this: CAST( expr AS type_name ) Or, you can run it as though it’s a subquery, using the MULTISET feature: CAST( MULTISET (subquery) AS type_name ) The parameters of the CAST function are: - expr (mandatory choice): This is the value or expression that is to be converted to another data type. - MULTISET (optional): This keyword indicates that the subquery results will return multiple rows, and are then CAST into a collection value. If this is omitted, and the subquery returns multiple rows, it will only return a single row. - subquery (mandatory choice): This is the subquery that can be run to be converted into a collection data type. - type_name (mandatory): This is the Oracle data type that the expr or subquery will be converted to. There are several data types that are compatible with the CAST function, both for converting from and to. You can find the full list in the article mentioned below. For more information about the Oracle CAST function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-cast/

Oracle ADD_MONTHS Function
 
03:15
https://www.databasestar.com/oracle-add_months/ The Oracle ADD_MONTHS allows you to add a specified number of months to a date value, and return the new date value. It’s great for performing calculations on dates, or date arithmetic, which can be hard in many different programming languages. The syntax of the ADD_MONTHS function is: ADD_MONTHS ( input_date, number_months ) The function returns a DATE value. The parameters of this function are: - input_date (mandatory): This is the starting date, or the date that you will add a number of months to. - number_months (mandatory): This is an integer value that represents the number of months to add to input_date. The input_date can be any datetime value, or even a character value that can be converted to a date. Also, the number_months can be any number value, or a character value that can be converted to a number. What if the number of days in the two months are different? For example, adding a month to Jan 31 could result in Feb 31, which does not exist. Well, in this case, Oracle would work out that the date does not exist, and use the last date of the month (e.g. Feb 28). You can also provide a negative value for ADD_MONTHS to subtract months from the specified date. For more information about the Oracle ADD_MONTHS function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-add_months/

MySQL 32 - FLOAT and DOUBLE Data Types
 
06:23
FLOAT and DOUBLE data types are data types that can be used to store numbers that can include decimal numbers. They are specifically used to store estimates. What do I mean? I mean that the precision of a FLOAT or DOUBLE value can be lost when doing math. The data types are only capable of maintaining a certain level of precision. The level of precision is usually adequate for most mathematical operations. If you need to store exact data, you will want to look into using the INT or DECIMAL data type instead. The numbers stored in a FLOAT or DOUBLE column are called floating point numbers, we'll see why in just a moment. Why are they called floating point numbers? let's look at a number. 150. This number could be represented as 150, or it could be represented as 1.5 * 10^2, or 1.5e2. With floating point numbers, scientific notation is used. These numbers are called floating point numbers because the decimal can float to different spots as we change the exponent. This means that the data type needs to store the number, how many decimal the number needs moved, and a sign bit. The benefit of floating point numbers is that they allow us to store pretty huge numbers. The down side is that they are not storing values exactly because they are limited in size. This means that only a certain level of precision is to be expected from a floating point data type. If you remember from the video of DECIMAL, precision is the number of digits in a number. As long as the precision for one of these data types exceeds the need for your specific data, the data type can work fine. For example, if you are storing a number like 15 trillion, you don't have to worry as much with precision as your number does not contain a lot of digits. This number can be represented as 1.5 x 10^13. This is a lot different than trying to store 1.5534534534 x10^13. Now we know both of these data types do not maintain a high number of digits correctly, but what is the difference between FLOAT and DOUBLE. The difference is the amount of storage they take up. Float takes up 4 bytes while DOUBLE takes up 8. The benefit in DOUBLE is that because it has more room to store data, it has a higher level of precision and can store bigger numbers. Now, what level of precision can you expect from either of these? FLOAT around 7 and DOUBLE around 15. Now, these data types are obnoxious because the exact values depend on your operating system and in general these monsters cannot be trusted. Especially when you start doing math with different numbers. In general, it is recommended to use the DOUBLE data type to have a higher level of precision and calculations in MySQL are done with DOUBLE. Always remember… prepare for trouble, make it double. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle GREATEST Function
 
02:43
https://www.databasestar.com/oracle-greatest/ The Oracle GREATEST function is a useful function, but I don’t think it’s very well understood. It returns the greatest or largest value in a set of values. You can provide the values, and use numbers or text values. The syntax for the Oracle GREATEST function is: GREATEST(expr1 [, expr_n]) The expr1 is the first expression to use for your comparison. Expr_n is one or more expressions to use in the comparison, separated by commas. This is optional. So how is GREATEST calculated? If the parameters are numeric, the GREATEST function finds the largest number. If the parameters are characters, the function finds the latest value if they were sorted alphabetically (using their character values). What data type is returned? It depends on the parameters you provide. It could be the same as the parameters you provide, or VARCHAR2 if the parameters are all characters. You can also use the GREATEST function with dates. It’s also the opposite of the LEAST function. For more information on the GREATEST function, including the SQL used in this video and the examples, read the related post here: https://www.databasestar.com/oracle-greatest/

MySQL 30 - INT Data Type
 
03:02
The last section of videos covered the string data types, now we are going to move on to the numeric data types. This video is going to discuss the INTEGER data types, or the INT data types. These data types are used to store whole numbers. That is, numbers without anything after a decimal. Just like with the TEXT data type, INT is broken up into multiple data types that can be used. It is actually broken up into 5 different data types. TINYINT, SMALLINT, MEDIUMINT, INT, BIGINT. Now, the confusing part here is the naming. That's because the only thing we have to compare this naming to is the TEXT data types. But they don't follow a consistent naming convention. For example, MEDIUMTEXT is larger than TEXT, but MEDIUMINT is smaller than INT. Additionally, there are 5 data types for the INT data type group, and lastly the biggest INT data type is called BIGINT whereas the biggest TEXT data type is called LONGTEXT. These are used to store exact values. What that means is that if you store a number and use it, you expect it to maintain precision. There are data types that are used for estimated values which we are going to discuss in more detail in an upcoming video. For now, let's focus on INT data types. You can find the exact storage limits for each of these, but here is some info: TINYINT - 255 SMALLINT - 65535 MEDIUMINT - 16 Million INT - 4 Billion BIGINT - Stinkin' a lot (18446744073709551615) Now note, in this situation, we will have to label each one of these as UNSIGNED. An unsigned number does not allow for negatives, but allows higher positive numbers. You can look up the INT data types to get the exact ranges for signed and unsigned. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

In this video, you’ll learn how to generate random alphanumeric characters in an SQL statement in Oracle SQL You can use Oracle SQL to generate random alphanumeric string values by using one of the built-in functions. This function allows you to specify the type of string to generate - upper or lowercase alpha characters only, mixed alpha characters, uppercase alphanumeric characters, or any printable characters. You can also specify the length of the string to generate, This can be a fixed number, or you can use another function to generate a random number to use for the length! You’ll see some examples of generating random alphanumeric string values in this video. For more information and tips on Oracle SQL, check out DatabaseStar.com: https://www.databasestar.com/

Oracle FLOOR Function
 
01:49
https://www.databasestar.com/oracle-ceil/ The Oracle FLOOR function will return the largest integer value less than the specified number. In other words, it rounds down to the nearest whole number. It’s the opposite of the CEIL function, which rounds up. The syntax of FLOOR is: FLOOR(number) The number parameter can be any numeric data type. The function will return a number in the same data type as the parameter. So, you can use FLOOR with decimal numbers, which is actually where FLOOR works best. You can use it with whole numbers too. It won’t show an error, it just might display the same value as provided (e.g. FLOOR(5) would be 5). You can also use functions inside FLOOR. For example, FLOOR(SUM(salary)) will SUM all of the salary values, and then round them down to the nearest whole number. Just like with all functions, the Oracle FLOOR function can also use column aliases. So, instead of having your column labelled “FLOOR(8.12)” or “FLOOR(salary)”, you can label your column “salary_rounded” or something that makes more sense. The FLOOR function is similar to the ROUND function. However, ROUND will round up or down, where FLOOR will always round down. The TRUNC function will also do some kind of rounding, but it removes decimals from a number which may cause it to “round” down. For more information, including the code used in the examples, read the related article here: https://www.databasestar.com/oracle-ceil/

Oracle SQL Tutorial 24 - Important Data Types
 
06:09
In the upcoming videos we are going to discuss data types in depth, but I don't want to drown you in all of the details. Because of that, I'm giving you this video which is going to introduce you to the most important data types. Then, in the upcoming videos, I'll describe them in more depth. One of the data types we've already discussed in this video is NUMBER. This data type is used to, obviously, store a number. It can be used to store integers (whole numbers), or numbers with decimals. There are two other numeric data types you should know of. BINARY_FLOAT and BINARY_DOUBLE are both numeric data types that are known as floating point numbers. A floating point number is often used for large numbers that have decimal places where it is acceptable to not be completely precise. What I mean by this is that these numbers can only store numbers correctly up to a certain decimal point. If you need perfect precision, you will want to use the NUMBER data type. Now storing numbers is good sometimes, but occasionally you will want to store string data. String data can be any sequence of characters, including numbers. By telling the database that a column is a string data type, the database knows how to treat that column. There are four important string data types that you need to know about. The first two are CHAR and NCHAR. These data types are used to store a fixed-length string. So for example, you can say you want to store 12 characters. This means that every value for this column will be exactly 12 characters. If you insert less than 12 characters, the data will be padded with spaces. This means you will want to use one of these data types when every value in the column is the same length. What is the difference between CHAR and NCHAR? CHAR uses what is known as ASCII while NCHAR uses Unicode. The difference is what characters are allowed and how much space each character takes. ASCII takes up less space but only supports English, numbers, and some symbols. UNICODE allows you to store characters from multiple languages but takes up more space. Those were both fixed-length string. What if you want to store data that changes in length? That is where VARCHAR2 and NVARCHAR2 come in. When it comes to storing dates, the data types that are most important are DATE and TIMESTAMP. Date can be used to store dates and time. Timestamp is a data type that can be used to store an exact moment in time. Lastly, there are interval types. These store a date range. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Get Decimal/Float output from Integer Division in SQL Server - SQL Server Tutorial
 
02:47
In this video we will learn how to get decimal/float output from Integer division in SQL Server. I am creating this video to answer once of the question that I posted while back for TSQL Interview Question list "If I run Select 100/11 what output will I get?" When you divide Integer by an Integer in SQL Server, SQL Server returns Integer output. As we can see from our above example, SQL Server output is Integer for Integers division. If we want to get float or Decimal output, Either our denominator or Numerator should be float or decimal type. If we have both denominator or numerator as Integers, we can use convert or cast functions to convert one of them to float/decimal so we can get our results as float/decimal. There are multiple techniques you can use to convert/cast to integer to float/decimal, here are some examples SELECT CAST(100 AS FLOAT) /11 AS OutputResult SELECT 100/CAST(11 AS FLOAT) AS OutputResult SELECT 100/CAST(11 AS DECIMAL(12,0)) AS OutputResult SELECT CAST(100 AS DECIMAL(12,0))/11 AS OutputResult Blog post link with scripts used in the video http://sqlage.blogspot.com/2015/02/how-to-get-decimail-output-from.html

Oracle MONTHS_BETWEEN Function
 
02:17
https://www.databasestar.com/oracle-months_between/ The Oracle MONTHS_BETWEEN function allows you to find the number of months between two dates. You can enter two dates and the function returns the difference. This function is often used as part of other calculations. Sometimes you’ll want to know the difference between two dates to perform other functions. The syntax of the MONTHS_BETWEEN function is: MONTHS_BETWEEN(date1, date2) What do these two parameters mean? The function performs date1 minus date2. So, if date1 is larger, the result is positive. If date2 is larger, then the result is negative. What data type is returned? It depends on the values you provide. If the dates are both on the same day of the month (e.g. both on the 10th of the month), then the result is an integer or whole number. If not, then the result will be a decimal value. For more information on the MONTHS_BETWEEN function, including the code used in this video and examples, read the related article here: https://www.databasestar.com/oracle-months_between/

Check if Value is Numeric by using ISNUMERIC & TRY_Convert Function in SQL Server - TSQL Tutorial
 
13:38
How to Determine if value is Numeric by using ISNumeric and Try_Convert Function in SQL Server - TSQL Tutorial ISNUMERIC( ) function is provided to us in SQL Server to check if the expression is valid numeric type or not. As per Microsoft it should work with Integers and Decimal data types and if data is valid integer or decimal, ISNumeric() should return us 1 else 0. But ISNUMERIC() does not work as expected with some of values specially when we have "-" or "d" in value and have two numbers after "d" such as 123d22, it still return us 1. Also if we have data in money format $XXXXX e.g $2000, It returns us 1. In SQL Server 2012. Microsoft introduced new function call Try_Convert( ). You can use try_convert function to convert to required data type and if it is not able to convert then it will return Null as output. As you will see below, I did some experiment and found out that Try_Convert will produce 0 for "-" when we try to convert to Int, That should not be happening as "-" is symbol not Integer. But when I try to convert "-" to decimal, Try_Convert produced Null output. Take a look in below results and keep in mind the outputs when you have to evaluate expression to Numeric or find out if expression is Numeric or Not.

Oracle TO_CHAR Function
 
04:13
https://www.databasestar.com/oracle-to_char/ The Oracle TO_CHAR function is a common and useful string manipulation function. It allows you to convert a number or a date value into a string value. It allows you to take a number or a string, and convert it to a VARCHAR2 data type. The syntax of the function is: TO_CHAR( input_value, [format_mask], [nls_parameter] ) The parameters are: - input_value: this is the value to convert to a VARCHAR2 value. It can be one of many different number or date data types. - format_mask is an optional parameter and allows you to specify the format to display the output as. If this is omitted, the function uses a default format. - nls_parameter: this is also optional and lets you determine a regional parameter for displaying the output value. The format mask helps you determine what your output is displayed as. For example, if you provide the date of May 3rd, and the output is ‘03/05/2018’, how do you know if this is May 3rd or March 5th? Using a format mask can specify which format is used. The function is similar to the TO_NUMBER and TO_DATE functions, in that they both convert a specific data type. For more information about the Oracle TO_CHAR function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-to_char/

Oracle CURRENT_DATE Function
 
01:54
https://www.databasestar.com/oracle-date-functions/ The Oracle CURRENT_DATE function is used to return the current date in the session timezone. The session timezone is the timezone that the current user is logging in from. This can be different from the database’s timezone. The syntax of the CURRENT_DATE function is: CURRENT_DATE No parameters are needed - just the function name. The function returns a DATE data type, and it includes hours, minutes, and seconds. This is good to know because the default display format for DATE does not include the time component, and it can be easy to forget. It’s different to the SYSDATE function as SYSDATE returns the date in the database timezone, and CURRENT_DATE returns the date in the session time zone. So, if I’m logging in from Melbourne, Australia, and the database is in London, England, then the CURRENT_DATE will return a date and time that’s 10 hours ahead of SYSDATE. It may be on the same day, or it could be a different day, depending on when I run the function. You can perform arithmetic on this function just like any other date value (e.g. CURRENT_DATE - 7 for 7 days ago). For more information about the Oracle CURRENT_DATE function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-date-functions/
