Syntax

DAY (date )

Arguments

  • date
    Is an expression that can be resolved to a time, date, smalldatetime, datetime, datetime2, or datetimeoffset value. The date argument can be an expression, column expression, user-defined variable or string literal.

Return Type

int

Return Value

DAY returns the same value as DATEPART (day, date).

If date contains only a time part, the return value is 1, the base day.

Examples

The following statement returns 30. This is the number of the day.

SELECT DAY('2007-04-30T01:01:01.1234567 -07:00');

The following statement returns 1900, 1, 1. The argument for date is the number 0. SQL Server interprets 0 as January 1, 1900.

SELECT YEAR(0), MONTH(0), DAY(0);
