SQL Date Comparison - How to filter Datetime in SQL Server - SQL Training Online
http://www.sqltrainingonline.com SQL Date Comparison - How to filter Datetime in SQL Server - SQL Training Online In this video, I show you how to do a SQL Date Comparison in SQL Server when your Datetime has an actual time in it. I also include the latest trick that will make this easier if you are using SQL Server 2008 or SQL Server 2012. How do you compare a Datetime in SQL Server? A SQL Datetime stores both Date and Time. So when you are filtering using the SQL Where clause, you have to know if you Datetime is storing the time also. Let's take a look at the employee table in SQL Training Online Simple DB The column we are looking at is the hire date. I want to go after the person who was hired on February, 22 2005. So, I use the following SQL. select * from employee where hire_date='02/22/2005' Now, this works because we don't have any times stored in this column. But, if I change the record from 2005-02-22 00:00:00.000 to 2005-02-22 08:22:25.000 and rerun the query, you see that I don't get any results. That is because the value of 02/22/2005 is really 2005-02-22 00:00:00.000 and I just changed the hire_date to include a time other than 00:00:00.000. So, I have to tweak my query to use a greater than and less than sign. This works. But, to really understand what is going on, let me show you what SQL Server really sees. There are other ways, and in this StackOverflow article you can read more about these other ways. But, I want to point out a few. If you are working in SQL Server 2005 or earlier, the following is supposed to be the fastest performing way to do this. select datediff(dd,0, hire_date),* from employee where dateadd(dd,0, datediff(dd,0, hire_date)) = '2005-02-22' But, if you are working in SQL Server 2008 or SQL Server 2012, they have introduced an actual Date datatype that doesn't include the Time portion. Since this is the case, you can use the CAST function to remove the time from the Datetime. Here is the SQL to do that. select * from employee where CAST(hire_date AS Date) = '2005-02-22' And that's it. If you enjoy the video, please give it a like, comment, or subscribe to my channel.

It allows separation of the software that generates messages, the system that stores them, and the software that reports and analyzes them. Each message is labeled with a facility code, indicating the software type generating the message, and assigned a severity label. Computer system designers may use syslog for system management and security auditing as well as general informational, analysis, and debugging messages. A wide variety of devices, such as printers, routers, and message receivers across many platforms use the syslog standard. This permits the consolidation of logging data from different types of systems in a central repository. Implementations of syslog exist for many operating systems. NTP: Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks. In operation since before 1985, NTP is one of the oldest Internet protocols in current use. NTP was designed by David L. Mills of the University of Delaware. NTP is intended to synchronize all participating computers to within a few milliseconds of Coordinated Universal Time (UTC). It uses the intersection algorithm, a modified version of Marzullo's algorithm, to select accurate time servers and is designed to mitigate the effects of variable network latency. NTP can usually maintain time to within tens of milliseconds over the public Internet, and can achieve better than one millisecond accuracy in local area networks under ideal conditions. Asymmetric routes and network congestion can cause errors of 100 ms or more. The protocol is usually described in terms of a client-server model, but can as easily be used in peer-to-peer relationships where both peers consider the other to be a potential time source. Implementations send and receive timestamps using the User Datagram Protocol (UDP) on port number 123.[4][5] They can also use broadcasting or multicasting, where clients passively listen to time updates after an initial round-trip calibrating exchange. NTP supplies a warning of any impending leap second adjustment, but no information about local time zones or daylight saving time is transmitted. The current protocol is version 4 (NTPv4), which is a proposed standard as documented in RFC 5905. It is backward compatible with version 3, specified in RFC 1305 Transcription: The first thing I need to do is configure the NTP server. So on the NTP server, go to NTP and I’ll enable the NTP service. I’m not going enable authentication at this point. I can then specify the date and time. This is okay for this lab. The clock on the local PC is the 12th of April 2018; time is 4:38 am. We’re told to check the time on the router and the switch first. At the moment show clock shows us that the router thinks it’s in 1993. The switch thinks it’s also 1993. So the time is wrong on both these devices. Before we configure NTP, let’s send timestamp messages to the syslog server. So at the moment, the syslog server is not showing timestamps on syslog messages. So on the router, I’m going to type service timestamps log messages date and time and milliseconds Notice the difference now when I type end we can see the date and time on the syslog message. But it’s the wrong date and time. So that doesn’t really help us with troubleshooting. We want to know when something took place. So we want date and time as well as milliseconds. But again, the switch as showing the wrong date and time. So we need to fix that, so, on the router ntp server We need to specify the IP address of the NTP server; NTP server has this IP address So specify IP address of NTP server. When I type end now and press Enter. Notice the correct date and time is displayed on the syslog message. It’s the 12th of April 2018, the time is 4:42 am. So that’s good. Configure the switch, so ntp server type end Notice the correct date and time is displayed. We’re getting messages from both the router and the switch. We’re told to verify the date and time on the router and the switch. So on the router show clock shows the correct date and time.

Hibernate Tip: How to use a timestamp for versioning and optimistic locking
Get more recipes like this one in my new book Hibernate Tips: More than 70 solutions to common Hibernate problems: https://goo.gl/XfywNk When you had to map a legacy table model in one of your projects, you probably know this situation. Instead of a numeric version column, the table model uses the timestamp of the last update. I don’t recommend using this approach because numeric versioning is much more efficient. But if you have to, you can also use a timestamp for versioning with JPA and Hibernate. If you like this video, please give me your thumbs up and share it with your friends and co-workers.

Difference between DateTime and DateTime2 in SQL Server
datetime vs datetime2 sql server In this video we will discuss the difference between DateTime and DateTime2 in SQL Server The date range for DateTime is January 1, 1753, through December 31, 9999 where as for DateTime2 it is January 1, 0001, through December 31, 9999 The time range for DateTime is 00:00:00 through 23:59:59.997 where as for DateTime2 it is 00:00:00 through 23:59:59.9999999 Accuracy for DateTime is 3.33 Milli-seconds where as for DateTime2 it is 100 nanoseconds Storage size for DateTime is 8 Bytes where as for DateTime2 it is 6 to 8 Bytes (Depending on the precision required) The default value for both DateTime and DateTime2 is the same - 1900-01-01 00:00:00 DATETIME2 has a bigger date range than DATETIME. Also, DATETIME2 is more accurate than DATETIME. So I would recommend using DATETIME2 over DATETIME when possible. I think the only reason for using DATETIME over DATETIME2 is for backward compatibility. DateTime2 Syntax : DATETIME2 [ (fractional seconds precision) ] With DateTime2 Optional fractional seconds precision can be specified The precision scale is from 0 to 7 digits The default precision is 7 digits For precision 1 and 2, storage size is 6 bytes For precision 3 and 4, storage size is 7 bytes For precision 5, 6 and 7, storage size is 8 bytes Text version of the video http://csharp-video-tutorials.blogspot.com/2015/10/difference-between-datetime-and_21.html Slides http://csharp-video-tutorials.blogspot.com/2015/10/difference-between-datetime-and_20.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

Date and Time Functions in SQL SERVER Part I || CURRENT_TIMESTAMP and DATEADD
This video will provide you the details of each Date and Time Data Types and Function in SQL Server 2014. I'll be walking through each and every kinds of build in function which are available in SQL Server in my next videos. Date and Time Data Types and Functions :-  CURRENT_TIMESTAMP (Transact-SQL) Returns the current database system timestamp as a datetime value without the database time zone offset. This value is derived from the operating system of the computer on which the instance of SQL Server is running. This function is the ANSI SQL equivalent to GETDATE.  Syntax CURRENT_TIMESTAMP  Arguments Takes no arguments.  Return Type Datetime  Remarks Transact-SQL statements can refer to CURRENT_TIMESTAMP anywhere they can refer to a datetime expression.CURRENT_TIMESTAMP is a nondeterministic function. Views and expressions that reference this column cannot be indexed. *********************************************************************  DATEADD (Transact-SQL) Returns a specified date with the specified number interval (signed integer) added to a specified datepart of that date.  Syntax DATEADD (datepart , number , date )  Arguments datepart Is the part of date to which an integernumber is added. The following table lists all valid datepart arguments. User-defined variable equivalents are not valid. datepart Abbreviations year yy, yyyy quarter qq, q month mm, m dayofyear dy, y day dd, d week wk, ww weekday dw, w hour hh minute mi, n second ss, s millisecond ms microsecond mcs nanosecond ns number Is an expression that can be resolved to an int that is added to a datepart of date. User-defined variables are valid. If you specify a value with a decimal fraction, the fraction is truncated and not rounded. date Is an expression that can be resolved to a time, date, smalldatetime, datetime, datetime2, or datetimeoffset value. date can be an expression, column expression, user-defined variable, or string literal. If the expression is a string literal, it must resolve to a datetime. To avoid ambiguity, use four-digit years. For information about two-digit years,  Return Types The return data type is the data type of the date argument, except for string literals. The return data type for a string literal is datetime. An error will be raised if the string literal seconds scale is more than three positions (.nnn) or contains the time zone offset part.  Return Value  datepart Argument dayofyear, day, and weekday return the same value. Each datepart and its abbreviations return the same value. If datepart is month and the date month has more days than the return month and the date day does not exist in the return month, the last day of the return month is returned. For example, September has 30 days; therefore, the two following statements return 2006-09-30 00:00:00.000: SELECT DATEADD(month, 1, '2006-08-30'); SELECT DATEADD(month, 1, '2006-08-31');  number Argument The number argument cannot exceed the range of int. In the following statements, the argument for number exceeds the range of int by 1. The following error message is returned: "Msg 8115, Level 16, State 2, Line 1. Arithmetic overflow error converting expression to data type int." SELECT DATEADD(year,2147483648, '2006-07-31'); SELECT DATEADD(year,-2147483649, '2006-07-31');  date Argument The date argument cannot be incremented to a value outside the range of its data type. In the following statements, the number value that is added to the date value exceeds the range of the date data type. The following error message is returned: "Msg 517, Level 16, State 1, Line 1 Adding a value to a 'datetime' column caused overflow." SELECT DATEADD(year,2147483647, '2006-07-31'); SELECT DATEADD(year,-2147483647, '2006-07-31');  Return Values for a smalldatetime date and a second or Fractional Seconds datepart The seconds part of a smalldatetime value is always 00. If date is smalldatetime, the following apply: • If datepart is second and number is between -30 and +29, no addition is performed. • If datepart is second and number is less than-30 or more than +29, addition is performed beginning at one minute. • If datepart is millisecond and number is between -30001 and +29998, no addition is performed. • If datepart is millisecond and number is less than -30001 or more than +29998, addition is performed beginning at one minute.

MySQL (/maɪ ˌɛskjuːˈɛl/ "My S-Q-L", officially, but also called /maɪ ˈsiːkwəl/ "My Sequel") is (as of March 2014) the world's second most widely used open-source relational database management system (RDBMS). It is named after co-founder Michael Widenius's daughter, My. The SQL phrase stands for Structured Query Language. The MySQL development project has made its source code available under the terms of the GNU General Public License, as well as under a variety of proprietary agreements. MySQL was owned and sponsored by a single for-profit firm, the Swedish company MySQL AB, now owned by Oracle Corporation. This video is targeted to blind users.

File system
In computing, a file system (or filesystem) is used to control how data is stored and retrieved. Without a file system, information placed in a storage area would be one large body of data with no way to tell where one piece of information stops and the next begins. By separating the data into individual pieces, and giving each piece a name, the information is easily separated and identified. Taking its name from the way paper-based information systems are named, each piece of data is called a "file". The structure and logic rules used to manage the groups of information and their names is called a "file system". There are many different kinds of file systems. Each one has different structure and logic, properties of speed, flexibility, security, size and more. Some file systems have been designed to be used for specific applications. For example, the ISO 9660 file system is designed specifically for optical discs. This video is targeted to blind users.

A JVM Does That?
Google Tech Talk (more info below) March 29, 2011 Presented by Cliff Click, Azul Systems. ABSTRACT Just what the heck is a JVM *supposed* to do? JVMs already provide a host of services. The 'J' part definitely slants the service selection and the 'V' part means that underneath the illusion there's a lot of really cruddy stuff. The success of these illusions has led to the real popularity of JVMs. In particular, JVMs are probably the most popular way to distribute ready-to-use GC technology to the masses, and the 2nd most popular way to distribute ready-to-use compilation technology (just behind "gcc" I'm guessing). Just what are these illusions? The illusion that bytecodes are fast and have a reasonable cost model : (machine code generation, profiling, JIT'ing). The illusion that you can quickly change the program at any time (dynamic class loading, deoptimization, re-JIT'ing). The illusion of infinite memory (Garbage Collection). The illusion of a consistent threading and memory model (the JMM, volatiles, locks). The illusion of quick time access (i.e. Intel's "rdtsc" is mostly useless for time). The illusion that these other illusions all work on all sorts of machines from cell phones to 1000-cpu mainframes (it's kinda sorta mostly true). But these are not enough! The People cry out for more illusions! The illusion of an Infinite Stack (tail recursion), the illusion that running-code-is-data (closures), the illusion that Integers are as cheap as 'ints' (autoboxing optimizations), or that BigIntegers are as cheap as 'ints' (tagged ints), the illusion that memory supports atomic update (software transactional memory), or the illusion that with enough hard work other language implementation experts can make a JVM run utterly different languages (invokedynamic). Meanwhile, JVM engineers labor under the illusion that they can maintain this giant piggy pile of code, and maybe even expand the provided services without it collapsing under it's own weight. Here's my take on what services could & should be provided by a JVM, what services probably belong to the next layer up (STMs, new concurrency models), and what services belong to the next layer down (fast time management, sane thread scheduling).
