Hi Stiju It's all to do with performing date calculations. The Date(xxx) function is ensuring that a date value is subtracted from another date value and the result will also be expressed as a date. If the ":nbdays" value is greater than 30 - in other words longer than a month then you won't be able to compare the result of the calculation directly. Personally I would always use the "Days(xxx)" function to ensure that you are comparing like for like, in this case the number of days difference between two dates.

Can u say logic behind that, I am bit cofused.

To make it also work correctly for more than 30 days it must be changed as > follows: > > C/EXEC SQL Delete from MyLib/MyFile > C+ where (Days(Current_Date) - > Days(Date(DateFieldOfMyFile))) > >= :nbdays > C/END-EXEC > > > > Birgitta > > -- > This is the RPG programming on the AS400 / iSeries (RPG400-L) mailing list > To post a message email: RPG400-L@xxxxxxxxxxxx > To subscribe, unsubscribe, or change list options, > visit: http://lists.midrange.com/mailman/listinfo/rpg400-l > or email: RPG400-L-request@xxxxxxxxxxxx > Before posting, please take a moment to review the archives > at http://archive.midrange.com/rpg400-l. > >
