in SAP
DB scheint das der Fall zu sein.
In ihrer Syntaxdefinition eines Triggers steht explizit nur "AFTER":
Zitat:
Syntax
<create_trigger_statement> ::= CREATE TRIGGER <trigger_name> FOR <table_name>
AFTER <trigger_event,..> EXECUTE (<routine>) [WHENEVER <search_condition> ]
<trigger_event> :: INSERT | UPDATE [(<column_list>)] | DELETE
<column_list> ::= <column_name> | <column_list>,<column_name>
