Re: SQL0305 Message in 5000 page joblog

Don,

This suggestion from Steve appears to be what you should be doing:

> select (sum(coalesce(uddamt,0) + coalesce(uddaoa,0) + coalesce(uddeam,0) - coalesce(uddcct,0) - coalesce(uddbkf,0)) into :sqlToaAmt from your_table

From what I can tell, you are using 4 files and selecting just one field, which is the sum over 5 fields. I can't tell from the names, but I'd guess that the 5 fields come from at least two different files.

So, probably one (or more) of the joined files has no matching record and the field from that file results in a null value. This null in turn results in the sum returning a null.

Depending on your underlying logic, the program may currently be returning incorrect results. I'd hazard a guess that if you change it to use coalesce, you'll get different results from the original program using the same data.

(Is the program checking SQLCOD or SQLSTATE after the select statement? If not, it should.)

Don,

I think that your math will fail as presented if any of the variables is null. I don't know if it would result in an SQL0305 error or not.

You need to resolve each potentially null variable before being able to use it in a SUM scalar function. I think that you will need something like:

select (sum(coalesce(uddamt,0) + coalesce(uddaoa,0) + coalesce(uddeam,0) - coalesce(uddcct,0) - coalesce(uddbkf,0)) into :sqlToaAmt from your_table

Otherwise you are attempting math on invalid values. Nulls aren't numbers after all.
