Zitat:

39. Mark appropriate PSQL functions as DETERMINISTIC
Mark your PSQL functions (in Firebird 3+) which do not have parameters and return constant values with keyword DETERMINISTIC. The deterministic functions are calculated and cached in the scope of the current query.

getestet habe ich das nicht, ist aber je nach bedarf bestimmt interessant....
