RE: As much as I hate showing my own stupidity more than once aday(Iam flat out stuck) Embedded SQL

Yes. In some situations, I find this to be incredibly handy. But
understood, it's not for every case. If you were reading your store
master and getting sales for locations, then this could be one of two
things. Either No sales or a combination of positive and negative sales
that equals 0. Perhaps the distinction would be visible to the users in
a drill down.

I understand, and I have verified that there is in fact data to be
returned....based on the date range, the customer number, etc. So just
zeroing out null isn't something I want to do...it'll mask the problem.

I like the solution Mark, will use it next time. But keep in mind that 0
and NULL aren't the same thing. You may want to handle the NULL
condition in your program. For example if you do a sum of the sales for
store 99, but there is no store 99. Therefore, store 99 didn't make 0 in
sales, it just plain old doesn't exist. =)

SELECT coalesce(SUM(SLEXT$), 0)

This will give you a value of 0 when the sum of SLEXT$ is null.

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.
