Oracle 12c Database New Features - Pluggable Database - Video 1
 
17:25
Oracle 12c Database New Features - Pluggable Database - Video 1 1. Pluggable Database * Oracle 12c introduces a new feature called 'Pluggable Database'. Here Oracle Metadata and user data are totally separated into two sections. One is Container DB (or CDB) which will hold Oracle Metadata. The other is Pluggable DB (or PDB) which will hold user data. How does a Pluggable Database work? In the regular database, Oracle's metadata and user's application data are integrated. For beginners, Oracle Metadata is the data that is present when you install a new Oracle Database (without any sample schemas). Even though it can be called as an empty database, it still has data provided by Oracle. This data is needed by the database to function. For example, the objects owned by SYS, SYSTEM are mostly metadata. Then user data is entered into that database. They will go under multiple user schemas. Now the database is being used by the users. Now a situation arises so that we need to create another database on the same server. Why? Let us say that you need to provide data to two clients. And you don't want one client to other's data. And your data is contained in an extensive set of application schemas. In this case, making a copy of those applications schemas into a different set of names and making them reside in the same database is very difficult. So, you provide two separate databases. This also ensures that there is no security violation. So, we install another new database, which comes with Oracle Metadata. Then we load the user data. In this method, which is currently being used (Year 2013), there will be a need for more memory for both the database instances. There will be two SGAs, two sets of smon, pmon and other background processes running. Then if we need to copy one database to another, we need to rely on extensive procedures which includes exporting the data from the source database first, then removing the data at the target and then finally loading the data in there. After that, we need to take care of the user security and object privileges etc. So, if you want to provide data for multiple tenants, that is multiple clients, then with the current set of features (till Oracle 11g), we have to create multiple databases. That is, one database for one client. In otherwords, there is no multi-tenancy. Multi-Tenancy is becoming an important requirement in cloud infrastructure, these days. You would like to have the ability of providing data to multiple clients from the same database system with full confidence in security. This can be achieved in Pluggable Database. In a Pluggable Database, Oracle basically separates its metadata entirely from the user data. Metadata is stored in a section called Container DB. Then the user data are stored in Pluggable DBs. It also stores user metadata in the Pluggable DB. By the way, what is user metadata? For example, earlier, the list of user accounts that exist in a database is tightly inegrated with Oracle Metadata. Now, with the separation of Container DB and Pluggable DB, the user accounts must exist in the Pluggable DB. So, the Pluggable DB not only contains user data, but also some user metadata. So, what are the benefits? * Multi-Tenancy - We can bring in two Pluggable DBs under one Container DB. Both will be totally segregated, but yet controlled by one instance. This is an important feature for SaaS (Software as a Service) platforms, Cloud, On-Demand and Vendor Managed Application solutions. * Easy cloning/copying. Now the cloning and copying the databases across servers would be much easier. Just clone a Pluggable DB and plug-it-in in a different server. * Very easy upgrades and patching.

Rank and Dense Rank in SQL Server
 
10:08
rank and dense_rank example difference between rank and dense_rank with example rank vs dense_rank in sql server 2008 sql server difference between rank and dense_rank In this video we will discuss Rank and Dense_Rank functions in SQL Server Rank and Dense_Rank functions Introduced in SQL Server 2005 Returns a rank starting at 1 based on the ordering of rows imposed by the ORDER BY clause ORDER BY clause is required PARTITION BY clause is optional When the data is partitioned, rank is reset to 1 when the partition changes Difference between Rank and Dense_Rank functions Rank function skips ranking(s) if there is a tie where as Dense_Rank will not. For example : If you have 2 rows at rank 1 and you have 5 rows in total. RANK() returns - 1, 1, 3, 4, 5 DENSE_RANK returns - 1, 1, 2, 3, 4 Syntax : RANK() OVER (ORDER BY Col1, Col2, ...) DENSE_RANK() OVER (ORDER BY Col1, Col2, ...) RANK() and DENSE_RANK() functions without PARTITION BY clause : In this example, data is not partitioned, so RANK() function provides a consecutive numbering except when there is a tie. Rank 2 is skipped as there are 2 rows at rank 1. The third row gets rank 3. DENSE_RANK() on the other hand will not skip ranks if there is a tie. The first 2 rows get rank 1. Third row gets rank 2. SELECT Name, Salary, Gender, RANK() OVER (ORDER BY Salary DESC) AS [Rank], DENSE_RANK() OVER (ORDER BY Salary DESC) AS DenseRank FROM Employees RANK() and DENSE_RANK() functions with PARTITION BY clause : Notice when the partition changes from Female to Male Rank is reset to 1 SELECT Name, Salary, Gender, RANK() OVER (PARTITION BY Gender ORDER BY Salary DESC) AS [Rank], DENSE_RANK() OVER (PARTITION BY Gender ORDER BY Salary DESC) AS DenseRank FROM Employees Use case for RANK and DENSE_RANK functions : Both these functions can be used to find Nth highest salary. However, which function to use depends on what you want to do when there is a tie. Let me explain with an example. If there are 2 employees with the FIRST highest salary, there are 2 different business cases 1. If your business case is, not to produce any result for the SECOND highest salary, then use RANK function 2. If your business case is to return the next Salary after the tied rows as the SECOND highest Salary, then use DENSE_RANK function Since we have 2 Employees with the FIRST highest salary. Rank() function will not return any rows for the SECOND highest Salary. WITH Result AS ( SELECT Salary, RANK() OVER (ORDER BY Salary DESC) AS Salary_Rank FROM Employees ) SELECT TOP 1 Salary FROM Result WHERE Salary_Rank = 2 Though we have 2 Employees with the FIRST highest salary. Dense_Rank() function returns, the next Salary after the tied rows as the SECOND highest Salary WITH Result AS ( SELECT Salary, DENSE_RANK() OVER (ORDER BY Salary DESC) AS Salary_Rank FROM Employees ) SELECT TOP 1 Salary FROM Result WHERE Salary_Rank = 2 You can also use RANK and DENSE_RANK functions to find the Nth highest Salary among Male or Female employee groups. The following query finds the 3rd highest salary amount paid among the Female employees group WITH Result AS ( SELECT Salary, Gender, DENSE_RANK() OVER (PARTITION BY Gender ORDER BY Salary DESC) AS Salary_Rank FROM Employees ) SELECT TOP 1 Salary FROM Result WHERE Salary_Rank = 3 AND Gender = 'Female' Text version of the video http://csharp-video-tutorials.blogspot.com/2015/10/rank-and-denserank-in-sql-server.html Slides http://csharp-video-tutorials.blogspot.com/2015/10/rank-and-denserank-in-sql-server_1.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists

Database vs Spreadsheet - Advantages and Disadvantages
 
07:06
In this video, we will focus on the advantages and disadvantages of spreadsheets vs databases. What is a spreadsheet? It is an electronic ledger, an electronic version of paper accounting worksheets. It was created to facilitate people who needed to store their accounting information in tabular form digitally. So, it is possible to create tables in a spreadsheet. This is one reason some people believe spreadsheets and databases are interchangeable, while, in reality, they aren’t. There are similarities between the two. Both can contain a large amount of tabular data and can use existing data to make calculations. Third, neither spreadsheets nor databases are typically used by a single person, so many users will work with the data. The differences between the two forms of data storage lie in the way these three characteristics are implemented. Ok. Imagine a spreadsheet. Every cell is treated as a unique entity. It can store any type of information – a date, an integer value, a string name. And then, not only can we have different types of values in various cells, but we can also apply a specific format to these cells. This is not inherent to databases. They contain only raw data. Each cell is a container of a single data value. It is the smallest piece of information there is. You must pre-set the type of data contained in a certain field. This feature prevents inadvertent mistakes – for example, in a field containing date values, should the user try to insert a string, the software will show an error and she will have the chance to correct herself. This won’t happen in Excel – if you insert a string in the column with date values, you wouldn’t obtain an error message, and Excel will store the string value.

Over clause in SQL Server
 
09:13
over partition by in sql server 2008 sql server over clause partition partition by clause in sql server 2008 over partition by clause in sql In this video we will discuss the power and use of Over clause in SQL Server. The OVER clause combined with PARTITION BY is used to break up data into partitions. Syntax : function (...) OVER (PARTITION BY col1, Col2, ...) The specified function operates for each partition. For example : COUNT(Gender) OVER (PARTITION BY Gender) will partition the data by GENDER i.e there will 2 partitions (Male and Female) and then the COUNT() function is applied over each partition. Any of the following functions can be used. Please note this is not the complete list. COUNT(), AVG(), SUM(), MIN(), MAX(), ROW_NUMBER(), RANK(), DENSE_RANK() etc. Example : SQl Script to create Employees table Create Table Employees ( Id int primary key, Name nvarchar(50), Gender nvarchar(10), Salary int ) Go Insert Into Employees Values (1, 'Mark', 'Male', 5000) Insert Into Employees Values (2, 'John', 'Male', 4500) Insert Into Employees Values (3, 'Pam', 'Female', 5500) Insert Into Employees Values (4, 'Sara', 'Female', 4000) Insert Into Employees Values (5, 'Todd', 'Male', 3500) Insert Into Employees Values (6, 'Mary', 'Female', 5000) Insert Into Employees Values (7, 'Ben', 'Male', 6500) Insert Into Employees Values (8, 'Jodi', 'Female', 7000) Insert Into Employees Values (9, 'Tom', 'Male', 5500) Insert Into Employees Values (10, 'Ron', 'Male', 5000) Go Write a query to retrieve total count of employees by Gender. Also in the result we want Average, Minimum and Maximum salary by Gender. This can be very easily achieved using a simple GROUP BY query as show below. SELECT Gender, COUNT(*) AS GenderTotal, AVG(Salary) AS AvgSal, MIN(Salary) AS MinSal, MAX(Salary) AS MaxSal FROM Employees GROUP BY Gender What if we want non-aggregated values (like employee Name and Salary) in result set along with aggregated values You cannot include non-aggregated columns in the GROUP BY query. SELECT Name, Salary, Gender, COUNT(*) AS GenderTotal, AVG(Salary) AS AvgSal, MIN(Salary) AS MinSal, MAX(Salary) AS MaxSal FROM Employees GROUP BY Gender The above query will result in the following error : Column 'Employees.Name' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause One way to achieve this is by including the aggregations in a subquery and then JOINING it with the main query as shown in the example below. Look at the amount of T-SQL code we have to write. SELECT Name, Salary, Employees.Gender, Genders.GenderTotals, Genders.AvgSal, Genders.MinSal, Genders.MaxSal FROM Employees INNER JOIN (SELECT Gender, COUNT(*) AS GenderTotals, AVG(Salary) AS AvgSal, MIN(Salary) AS MinSal, MAX(Salary) AS MaxSal FROM Employees GROUP BY Gender) AS Genders ON Genders.Gender = Employees.Gender Better way of doing this is by using the OVER clause combined with PARTITION BY SELECT Name, Salary, Gender, COUNT(Gender) OVER(PARTITION BY Gender) AS GenderTotals, AVG(Salary) OVER(PARTITION BY Gender) AS AvgSal, MIN(Salary) OVER(PARTITION BY Gender) AS MinSal, MAX(Salary) OVER(PARTITION BY Gender) AS MaxSal FROM Employees Text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/over-clause-in-sql-server.html Slides http://csharp-video-tutorials.blogspot.com/2015/09/over-clause-in-sql-server_29.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists
