DATEDIFF_IN_DAYS

Previous Next

Returns the difference between 2 timestaps expressed in number of days.

Syntax

DATEDIFF_IN_DAYS( date, date )

 

Both date values are required and must evaluate to a datetime. If at least one of the arguments contains time values, the function will deliver float values. To prevent this, use the TIMESTAMP_TO_DATE function to convert the argument(s) to a format that does not contain time information.

Example

SELECT    DATEDIFF_IN_DAYS( 
              TIMESTAMP_TO_DATE( SYSDATE ) 
          ,   TIMESTAMP_TO_DATE( start_date )
          )
FROM      project

Notes

This is a convertible function resolved by USoft and thus supported on all RDBMS platforms.
