The SQL GETDATE function is a built-in date and time function in SQL Server that returns the current date and time of the system. It is a non-deterministic function, meaning that it returns a different value every time it is called, depending on the current system time.
The syntax for the GETDATE function is simple. You can use it without any arguments, like this:
This will return the current date and time in the default format, which is yyyy-mm-dd hh:mi:ss.mmm (year-month-day hour:minute:second.millisecond).
You can also use the GETDATE function as part of other SQL statements. For example, you might use it to insert the current date and time into a table:
INSERT INTO MyTable (MyColumn, MyDate) VALUES ('Some data', GETDATE());
This would insert a row into MyTable, with the current date and time in the MyDate column.
In addition to GETDATE, SQL Server provides several other built-in date and time functions, such as DATEADD, DATEDIFF, and DATEPART, which can be used for a variety of date and time manipulation tasks. By using these functions in combination with GETDATE, you can perform a wide range of operations on dates and times in your SQL queries.
