This seems like it should be very easy...anyway, it is in MS SQL Server

In a DB2 stored procedure, how can I just get the value of a variable? Say I have the following stored procedure:

CREATE PROCEDURE etl.TestABC( 
) 
LANGUAGE SQL 
  BEGIN 
    declare      Stmt              varchar(2048); 
    set Stmt = 'this is a test';
-- print Stmt;
-- select Stmt;


    return 0; 
END @ 

I'd like to print out the value of Stmt after I set it. Print doesn't work, select doesn't work. Somebody said I have to insert it to a table first, and then get it after I run the stored procedure. Is this really necessary?

Thanks, Sylvia

EDIT: I should have made clearer that I want to see the value of Stmt each time after I set it, and I may need to set it multiple times within the same stored procedure.
