T-SQL 101: 69 Extracting date components in SQL Server T-SQL with DAY, MONTH, and YEAR

When you’re writing T-SQL code, it’s really common to need to extract components of a date, and the most common need is for year, month, and day. So T-SQL has separate functions just for that.

You can see the output from this query here:

The YEAR(), MONTH(), and DAY() functions take a date (or datetime, datetime2, smalldatetime) as input and return an integer for the year, month, or day.

You can also do this with the DATEPART() function but these are simpler and clearer when you want these main components of a date.
