No, but it would remove the unnecessary cursor, opens and fetchs.

Would that explain the error code of -305?

Doug, you are doing a sum with no group by... so a cursor is not needed
because only one result will be returned. You should simply say

SELECT SUM(SLEXT$) FROM SLSTRNL5
INTO :ZSUM
WHERE SLACCT= :CUSTNO
AND SLTDAT > :ZBDATEN
AND SLTDAT <= :ZEDATEN
AND SLCLAS > 1
AND SLSHRT = ' '

I am reading a file and using the values within that file to create
an
SQL
that will go out and select a sum of sales figures for a particular
customer.



Here is the relevant SQL code:



C*---Prepare SQL Statement

C/EXEC SQL

C+ DECLARE C1 CURSOR FOR

C+ SELECT SUM(SLEXT$) FROM SLSTRNL5

C+ WHERE SLACCT= :CUSTNO

C+ AND SLTDAT > :ZBDATEN

C+ AND SLTDAT <= :ZEDATEN

C+ AND SLCLAS > 1

C+ AND SLSHRT = ' '

C/END-EXEC





I then open the cursor with the following:



C*---Open the Cursor

C/EXEC SQL

C+ OPEN C1

C/END-EXEC



I then am running a fetch statement with the following:



C*---Fetch the Result and place into Variable

C/EXEC SQL

C+ FETCH C1 INTO :ZSUM

C/END-EXEC



ZSUM is defined as an 9,2 on the D spec



Everything so far, at least to my eyes looks good...



However before I process that ZSUM data (output to a report) I check
the
SQLCOD and I am getting a return code of -305..I have checked the
variables
that I am passing in, such as CUSTNO (defined on the D SPEC
correctly),
ZBDATEN and ZEDATEN are also defined on the D SPEC correctly...so I
have
no
clue what variable the system is balking at.



Any assistance would be appreciated.



Douglas
