No need to GROUP BY...

If you're "leaving out" records, the issue comes from the WHERE clause or join condition.

FROM FORCE nDebit1 LEFT JOIN companyid ;
ON ALLTRIM(nDebit1.companyid) == ALLTRIM(companyid.companyid)

A couple questions:

1. Do you have records which you want to appear, but they would only be captured by a RIGHT JOIN (CompanyID.CompanyID values not matched by nDebit1.CompanyID)?

2. Do the missing records not meet the join condition?

This is a data-driven issue, and the answer will be found in how your data matches the formulation of the query.

>works okay most of the time. Every now anthen it leaves out a few records. I read in the HAckers Guide that you should use GROUP BY when you have a calculation of some type in the Select statement. Does that apply when you are joining two tables?
