Q

"SUM" function in SQL

When using the "SUM" function in SQL, how do I override the systems default length of the field? Example: sum(widget_qty) as qty

The system generates a field length of 31,0. I would like it to be 9,0. This is causing a problem with my SQLRPGLE program, which will not compile due to the 31 position field length.

 

You just need to wrapper the SUM function with the CAST function. For example: CAST(SUM(widget_qty) AS DECIMAL(9,0)) as qty
