Either put all the code into the same AFTER PARAMETER FORM trigger (if possible), or create your own function(s)/procedure(s); to do that, use "Program Units" node of the Object Navigator window. Once you're done, call these procedures from the AFTER PARAMETER FORM trigger.

Just like any function you call in a PL/SQL block. As function returns a value, AFTER PARAMETER FORM trigger should have a variable declaration section; once you declare this variable, call a function as

  l_cnt := fun_count_employees(:par_deptno);

Or, if you are calling a procedure, it is even simpler - just name it:

  prc_do_something;

hi,
referring to your example to call the function in after parameter form

l_cnt := fun_count_employees(:par_deptno);

the "l_cnt" := is refer to what?is't the name of the function?

and the "fun_count_employees" is the variable that you declare right?

sorry..my question seems basic,because i am new in pl/sql..

thanks

l_cnt                 : variable
fun_count_employees   : function 
:par_deptno           : parameter

Perhaps you'd want to read PL/SQL User's Guide and Reference book found at Oracle 10g Documentation page.
