Hi !
I am analysing a cobol db2 program and need your hlep regarding the same.
Here is what I have in the program.
| Code: |
EXEC SQL
FETCH NEXT ROWSET LOCATION_CSR FOR :WS-LIT-FINAL ROWS
INTO :WS-LOCHIER-LOC-CDE1
END-EXEC.
PERFORM B2010-GET-DIAGNOSTICS-PARA THRU B2010-EXIT
EVALUATE SQLCODE
WHEN SQLCODE-SUCCESSFUL
PERFORM B3000-CLOSE-LOCATION-CSR THRU B3000-EXIT
MOVE ROW-COUNT TO WS-LIT-FINA
........................
B2010-GET-DIAGNOSTICS-PARA.
EXEC SQL
GET DIAGNOSTICS
:ROW-COUNT = ROW_COUNT, :NUM-CONDNS = NUMBER
END-EXEC.
EVALUATE SQLCODE
WHEN SQLCODE-SUCCESSFUL
CONTINUE
WHEN SQLCODE-ROW-NOT-FOUND
CONTINUE
WHEN OTHER
MOVE 'ERROR WHILE GET DIAGNOSTICS'
TO WS-ERR-ACTION
.............................................
|
My question here is.
According to my understanding, Evaluate SQLCODE should immediately follow the SQL stmt. Here in the code,
there is a PERFORM Stmt btw the FETCH sql stmt and EVALUATE SQLCODE. So here it looks like, the SQLCODE returned from the GET DIAGNOSTICS is being Evaluated twice (in the B2010-GET-DIAGNOSTICS-PARA & after the PERFORM B2010-GET-DIAGNOSTICS-PARA THRU B2010-EXIT). Please let me know if my understanding is correct or not.
Also, if the FETCH stmt is not successful, is there a chance of GET DIAGNOSTICS to be successful.
Thank you in advance,
Srinivas Vaddadi |

Hi Srinivas,
You are correct!!
The sql code returned from GET DIAGNOSTICS statement is being evaluated twice. This needs to be fixed.
Thanks,

In the 2nd SQL CODE check, Row Count, which is retrieved form the GET DIAGNOSTICS statement, is moved into some other variable. So you have to check the statements after
| Code: |
MOVE ROW-COUNT TO WS-LIT-FINA
|
And you have to add SQLCODE check after FETCH statement also. |
