Hi All,
I have a problem in hand.
I need to see whether data exists in DB2 table or not. I need to do the coding in cobol.(embedded)
I don't want to use Count as it will read through the entire table, also I don't want to fetch first record only as it will fetch a record, which i won't use. I just want to see whether data satisfying my where condition exists in the table or not.
i've goggled it and found something like -
IF EXISTS (SQL QUERY)
RETURN 1
ELSE
RETURN 0;
But this piece in not working in mainframe DB2, Is there something like the above exists for mainframe SQL ?
Thank you for your time, |

Sorry buddy,
I meant the given SQL is not getting executed in mainframe environment. |

wow, what a detailed, technical response.
in addition to what enrico has said about not providing any information,
why did you

and not look in a DB2 manual? (manual buttons at top of page)
had you, you would have discovered that the garbage you pulled out from google is not IBM.
perhaps:
SELECT 1
into :host-numeric-variable
FROM <your table>
WHERE <your conditions>
IF the sqlcode is +100 the data is not there.
an sqlcode of 0 or -811 would indicate that the data is there.

we are relaxed, otherwise we would not be wasting our time to try to help You..
our queries work, the Db2 tables do not need any recovery, out threads are not in a deadlock...
and we have no need to ask a forum....  |

I am trying to make You understand how to post sensible question in order to get useful answers.
and is a way to help You, to get useful answers in the shortest time
both my replies pointed out an illogic way of asking |

Hello,

Yes, certainly. . .
Demonstrating or pointing out completely non-productive and time-wasting ways to ask for help should help both you as well as others who might not understand how to ask for help without requiring a number of iterations.
If no one told you how bad this approach was, others might read this and believe it is proper to ask for help this way.
And it is not. . . |

just think about...
if You were a manager would You accept Your employees wasting "billing" consultants time with badly posed questions
meditate about it, but most probably not
here an even wore aspect emerges,
anybody can waste somebody else time because they do not pay for it..
and furthermore we get <******>remarks when we try to correct the
approach!
looks like this time You just did not behave according to Your signature |
