Hi

I am getting efficiency problem while running this db2 query in cobol program it takes more time to run. This query will fetch the columns based on the matching keys present in the table and file.

In the table the key is INTEGER and in the file the key is defined as s9(15) comp-3.
Code:

 EXEC SQL
    SELECT 
           DATE_OF_BIRTH
           FIRSTNAME
           SURNAME
           into hostvariables
FROM  table name
WHERE table-KEY = :W00-file-KEY
with UR

In the table the Integer key(INDEX) field contains 10 digits and i tried to move s9(15) comp-3 to s9(9) comp and it causes truncation of digits.

Is there any other solution to overcome this problem.

Regards
vijay

vijayakumar,

Define a working storage fiels Ws-file-KEY as

Code:

WS-file-KEY     PIC 9(18)


and move the s9(15) comp-3 variable to WS-file-key

Hope this helps...

Cheers
