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_variabl e := tcl_or_any_othe r_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.

Hello, I'm trying to build a PL/PGSQL function that will be called by a trigger which will update a table named 'mview_contacts'. That table plays the role of a materialized view. The 'plpgsql' language is installed on that database (there are already several functions inside) but I don't understand why I can't store that function in the database.

In Postgres 7.3.5 - When we try to insert a new record into our parties.party table which is then meant to fire off a trigger to update a column in the table with some de-normalised information, we get the following error: ERROR: FLOATING POINT EXCEPTION! The last floating point operation either exceeded the legal ranges or was a divide by zero. Can someone help spot our syntax erorr, please? Many thanks!
