Title: SQL: null values

Try SELECT IFNULL(MAX(NUMBER), 0) from ....)

that way if the Max(Number) returns null (say when the table has no rows), it will be returned as 0.

Subject: SQL: null values

Hi,

i have a question about null values in SQL.

I would like to use sql functions like SUM, MAX, MIN,...... in my SQLRPGLE program
The results of the sql, for example (select max(number) from......), i have to write in a file.

The problem is, that the "SUM"-field allows null values and i also use the SQLDA.

How can i change this ?

Stefan
