Re: As much as I hate showing my own stupidity more than once a day(I am flat out stuck) Embedded SQL

Well I actually checked the PF where the data is coming from and there are
no null values for the extended amount.....and there should never be a
null
value returned, so something else is amiss......I am concerned that
handling
nulls this way, will inadvertently mask a potential problem that needs to
be
addressed....

Told handle a null value just do.

1. Define an int like this in your program
D MYNULL S 5I 0 INZ(-1)
2.
SELECT SUM(SLEXT$) INTO :ZSUM:MYNULL
FROM SLSTRNL5
WHERE SLACCT= :CUSTNO
AND SLTDAT > :ZBDATEN
AND SLTDAT <= :ZEDATEN
AND SLCLAS > 1
AND SLSHRT = ' '

Should do it.

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
