Who said wrong ? who said SQL ? I thougth _WHY_ the IF control structure has exactly two alternate blocks ? a BOOLEAN expression has exactly two possible values, that's why !

That's your point, but why ? ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
