That's what's in that page: a UDF (user defined function) named getapplicationid() that will return the user login / name / whatever and triggers. What is preventing you from writing that? What is your doubt with regards to how create that feature on your database? -- Jorge Godoy <jgodoy@xxxxxxxxx>
