DATEPART (SSIS Expressions)

Returns an integer representing a datepart of a date.

Syntax

DATEPART(datepart, date)

Arguments

  • datepart
    Is the parameter that specifies for which part of the date to return a new value.

  • date
    Is an expression that returns a valid date or a string in date format.

Result Types

DT_I4

Remarks

DATEPART returns a null result if the argument is null.

A date literal must be explicitly cast to one of the date data types. For more information, see Integration Services Data Types.

Note

The expression fails to validate when a date literal is explicitly cast to one of these date data types: DT_DBTIMESTAMPOFFSET, DT_DBTIMESTAMP2, and DT_DBTIME2.

The following table lists the dateparts and abbreviations recognized by the expression evaluator. Datepart names are not case sensitive.
