You can USE SELECT DISTINCT... or a GROUP BY clause in a SQL Select statement to get the unique values:

If you have a table INVLINES (INVNO, INVAMT), you could:

SELECT DISTINCT INVNO FROM INVLINES TO CURSOR UNIQINVS

to just get the unique InvNo values, or

SELECT INVNO, SUM(INVAMT) AS INVAMTTOT FROM INVLINES GROUP BY INVNO

to get the unique InvNo along with the sum of theInvAmts from the matching records.
