I have a function, call it 'functionMain'. And I have several tables that each have trigger functions. Each trigger function needs to call 'functionMain' (with different parameters).
table A => trigger function A ==> functionMain table B => trigger function B ==> functionMain table C => trigger function C ==> functionMain 'functionMain' returns VOID (runs an insert statement). and has an exception/raise exception block. An insert transaction for table A is launched (insertA), trigger function A is called, 'functionMain' is called and 'functionMain' fails. Hence, trigger function A needs to rollback. Questions: a) I am assuming that the trigger functions should use 'PERFORM functionMain(....)'? b) if 'functionMain' fails, then 'funtionMain' automatically performs an implicit rollback, correct? c) if 'functionMain' fails, should the trigger function also contain an exception handler or will the rollback from 'functionMain' cascade up to the original transaction (insertA)?
