I am uing the following SQL statement:

SELECT LINE.cCode, SUM(ROLLS.nWeight_Roll) AS nAccepted ;
FROM LINE ;
LEFT JOIN ROLLS ;
ON LINE.ID=ROLLS.clineid ;
WHERE UPPER(ALLTRIM(CSTATUS))=="ACCEPTED" ;
GROUP BY LINE.cCode ;
INTO CURSOR tmpProduction

In my LINE table, I have 11 records. cCode={101,102,103....,111}.
ROLLS table is the rolls produced on a particulare line/machine-line.

I would like to have 11 records after my SQL statement executes in the temporary cursor, however I only get 5. This is because 6 of the lines have no ROLL records associated with them since no production was ever performed on those lines yet.

How can I request that all lines are given, even if the SUM returns 0.00?

Thanks in advance,
