db2 print message within procedure

3 New Member
Hi all :)

I like to be able to print messages throughout my long procedure statement.

I can currently use "!echo my message@" outside of my procedure BUT not able to figure out how to do this inside the procedure.

Any help would be greatly appreciated.

You cannot print directly to standard output device from a stored procedure. However, you can redirect your output to a file. Again, this is possible only if your stored procedure definition is written in a language than SQL/PL.

You can implement file handling.

By the way, what do you want to achieve from doing this?

Deniz, as far as I can guess you'd like to echo some debug messages, like "stored procedure at point 3", right?

Now that a direct output isn't possible (Thanks Sanjay, I wouldn't have known), I suggest another approach. Create a separate table "debugtext" with columns (when datestamp, txt varchar(255)) and insert your messages into it while inside the stored procedure:

Expand|Select|Wrap|Line Numbers
  2.   debugtext
  4.   ( current_datestamp, 'stored proc at point 7' );
Sanjay, this should be possible, shouldn't it?

I noticed I can't push a value into a text box by saying something like, "txtThisTextBox = intSomeVariable * 0.5" because I get an run-time error saying I can't assign a value to this object. So instead I made the control source a function to pull the value from the function. That works. Inside the text box I simply write something like =SomeFunction(). Beautiful. Works great.
