Обсуждение: how to call a TCL function from within a plpgsql trigger?

Hi list,

That's the question, anyone knows a way to do that?

Thanks in advance,

Josue Maldonado.

A tcl function is just like any other, you can call it from within a
plpgsql trigger function  in the same way you would call a built-in, or
any other function.  Having said that, I am not sure what the exact
plpgsql options are besides "SELECT myfunction(' 'foo' ', ' 'bar' ')
...." and don't know syntax for storing the returned value in a
variable.  I'm a one-trick pony.

What about

     plpgsql_variable := tcl_or_any_other_function();

You can also pass some arguments, but that doesn't count as another
trick, it's just a modification to an already seen one.
