Hi all,
I'm trying to create a trigger.
I created a function which returns a count of the rows. I used this
procedure while creating the trigger. But, I get an error stating SQL
must return opaque. I tried the same with returning a varchar. I get
the same error again.
In simple words, I need to create a trigger. Can anyone help me in
doing this. BTW, what is similar fxn. as dbms_output.println() in
Oracle.
Thanks in advance.
