ADD_DAYS

Previous Next

Adds a specified number of days to a date.

Syntax

ADD_DAYS( date, number-of-days )

The required date must evaluate to a datetime. The required number-of-days must be an integer.

 

Example 1

UPDATE   tab1
SET      next_year = ADD_DAYS( SYSDATE, 365 )

 

 

Example 2

UPDATE   schedtour
SET      must_end = ADD_DAYS( start_date, 40 )
WHERE    limited = 'Y'

Notes

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

On Oracle and SQL Server, in additions and subtractions involving a date value and a numeric value, the numeric value is automatically converted to a date value (1 is interpreted as 1 day). On JDBC/Derby, ADD_DAYS must be used to achieve this conversion.
