    Hi,
    I am trying to create triggers for all the tables in my schema which have a created_date column.

    Since there are 100's of tables which have that column I wrote a small sql statement which will generate the create trigger statement for me.

    This is what i am doing....

    select 'Create or replace Trigger '||table_name||'_Trigger BEFORE INSERT OR
    UPDATE ON '||
    table_name||' for each row BEGIN IF inserting THEN
    :NEW.created_date:=sysdate; :NEW.created_by:=user; END IF; If Updating
    then :NEW.updated_date:=sysdate; :NEW.updated_by:=user; end if; END; /'
    from dba_tab_columns where column_name='CREATED_DATE'

    I spool the above query into a file and execute it.

    It would work fine , but the only problem is the / at the end of the
    procedure it creates. The / should appear on the next line and I am not able
    to do so. Is there a way I can force a carriage return before the /.

    If i manually edit the output of the above query so that the / appears on
    the next line of each result set, it works great.

    Please suggest

    Thanks

    Thanks Pando,

    This works great.

    But how do i set the linesize.
    If I leave it default it goes to the next line after the 80th column and then it does not compile properly.

    If I set it to 1000 then its too big.

    Is there a way to handle this.

    Thanks
