    sql query

    Hello,
    lets say i have a query like
    select isin_no from test_asset where isin_no = 'CH0024899483';

    and the query returns 'no data found' error ora-01403

    can we compare like

    if (select isin_no from test_asset where isin_no = 'CH0024899483') = 'ora-01403' then
    ...
    end if;

    Is it part of a PL/SQL block, isn't it?

    You have to include EXCEPTION section with an entry for WHEN NO_DATA_FOUND THEN do-whatever-you-have-to-do-in-this-case

    Hi,
    it is part of a plsql block.
    But if the control gets into the exception block we cant get into main block again right?

    i need to continue with the main block after this process..is it feasible?

    If that's the case I would add logic to test if there is a row matching your condition then, if the row exists read it.

    You can test resorting to an IF EXIST clause or a select count(*) > 0

    Having said that, I would certainly include an EXCEPTIONS section.
