are there static variables in pgsql? - Mailing list pgsql-general

i am writing a recursive procedure in pl/pgsql.
i need to check whether a condition is true in any step of recursive calls.

if i get a true response in one call, i wont make other recursive calls anymore, because i get what i need.
if no one gives me a true response, then uppest procedure will return false as a result.

i think i may achieve this with a static variable(shared among all calls).

is it possible?

or another solution?

thanks a lot for any help.
