SQL Server has a bunch of functions that return the current date/time. Two of these are the GETDATE() and SYSDATETIME() functions.
At first glance, these two functions appear to do the same thing – get the current date and time from the operating system of the computer on which the instance of SQL Server is running.
However, there’s a subtle difference between the two.
In SQL Server, just as you can use T-SQL to get the month name from a date, you can also use the same methods to get the day name. By day name, I mean Monday or Tuesday for example, and not the date number or number of the day of the week (which you can also get if you need it).
Here are three ways to return the day name from a date in SQL Server using T-SQL.
When using SQL Server, you have a few different options when you need to return the month name from a date using T-SQL. By month name, I’m not talking about the month number (such as 07). I’m talking about the full name of the month (such as July).
For example, when given a date of 2018-07-01, you want July to be returned.
This article presents three ways to return the month name from a date in SQL Server using T-SQL.
When a new login is created in SQL Server, it is assigned a default language. This language is used for system messages and date/time formats. This language will be used as the default language whenever that login connects to SQL Server (but it can also be changed to a different language within the session).
If you ever wish to find out the language that’s assigned to the current session, you can run one of the options on this page.
In SQL Server, you can set the language to be used for the current session. The current language setting determines the language used on all system messages, as well as the date/time formats to use.
This article demonstrates how to use T-SQLÂ to set the current language environment in SQL Server.
Perhaps you’ve encountered the T-SQLÂ PARSE(), CAST(), and CONVERT() functions when working with SQL Server and wondered what the difference is. All three functions seem to do the same thing, but there are subtle differences between them.
In this article I aim to outline the main differences between these functions.
In SQL Server, the PARSE() and TRY_PARSE() functions are used for translating a value into another data type. They essentially do the same thing, with one exception; how they deal with errors.
If PARSE() fails when attempting to parsing to a different data type, it will return an error. If TRY_PARSE() fails, it will return NULL.
If you need to convert a string into a date/time value in SQL Server, you have a number of options. In this post I outline six T-SQL functions that allow you to do this.
The six functions are:
CAST()CONVERT()PARSE()TRY_CAST()TRY_CONVERT()TRY_PARSE()Below are example of how you can use these functions to convert a string to a date/time data type.
If you work with SQL Server, chances are you’ve used at least one of the CONVERT() or CAST() functions to convert from one data type to another. If you’ve ever encountered an error while trying to convert a string to a date/time data type, the PARSE() function could be what you need.
For example, if you have a string like say, Fri, 20 Jul 2018, the CONVERT() or CAST() functions will throw an error. But the PARSE() function will handle it without a problem.
The PARSE() function returns the result of an expression, translated to the requested data type in SQL Server. So you can use it to “translate” your string value into a date/time data type (such as date, datetime, datetime2, etc).
When using SQL Server, you can convert a date/time value into a string by using the CONVERT() function. This function allows you to convert between different data types.
In this article, we’ll be converting between various date/time data types to a varchar or nvarchar string.
One of the good things about this function is that it allows you to specify the style that the date will be returned in. For example, you can specify whether it’s returned as mm/dd/yyyy, yyyy.mm.dd, Mon dd, yyyy, etc. You can also specify whether the time component is returned and how it’s styled.
