T-SQL has a function called DATETIMEOFFSETFROMPARTS() that allows you to get a datetimeoffset value from the various separate parts of a date. Specifically, it returns a datetimeoffset value for the specified date and time and with the specified offsets and precision.
Examples of this function below.
In SQL Server, the DATETIME2FROMPARTS() function works similar to the DATETIMEFROMPARTS() function, except that it accepts 8 arguments and returns a datetime2 value. The DATETIMEFROMPARTS() function on the other hand, accepts just 7 arguments and it returns a datetime value.
Basically, you provide all the date/time parts and this function will return a datetime2 value based on the parts you provide.
In SQL Server, the DATETIMEFROMPARTS() function works just like the DATEFROMPARTS() function, except that it also returns the time portion of the date.
The DATETIMEFROMPARTS() function accepts seven arguments, each representing a different part of the date/time. The function then returns a datetime value from the given parts.
You can use the T-SQL DATEFROMPARTS() function in SQL Server to return a date value that maps to the date parts that you provide as integer expressions.
The way it works is, you provide three values (one for each of the year, month, and day values), and SQL Server will return a date value based on the values you provide.
Examples below.
You can use ODBC scalar functions when running T-SQL statements in SQL Server. There are various types of ODBC scalar functions, including string functions, numeric functions, system functions, and of course, date/time functions (also referred to as date, time, and interval functions).
Below are examples of the date, time and interval functions you can use in SQL Server.
SYSUTCDATETIME() and GETUTCDATE() are two T-SQL date/time functions available for use in SQL Server. These functions return the date and time of the computer on which the instance of SQL Server is running. Both functions return the date and time as UTC time (Coordinated Universal Time).
So, both functions do the same thing. Almost.
Here’s how these two functions differ:
GETUTCDATE() returns its value as a datetime value.SYSUTCDATETIME() returns its value as a datetime2 value.This means that SYSUTCDATETIME() provides more seconds precision. The datetime2 data type also has a larger range than datetime.
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.
Each time you create a new login in SQL Server, you have the choice of assigning a default language to that login. If you don’t do this, the login will use the default language as specified in the default language server configuration option.
This article demonstrates how to set the default language server configuration option in SQL Server, using T-SQL.
