Not sure but got a feeling that it has something to do with the "Purity
Level" of the function. Something you declare with PRAGMA RESTRICT_REFERENCES
For a function to be usable in the DMLs, it needs to satisfy a few purity
rules, which also need to be explicitly declared using PRAGMA
RESTRICT_REFERENCES. Guess this might be the case in triggers as well.

Hey all,
The subject says it all. In 8.1.7, can I:
CREATE OR REPLACE TRIGGER my_trigger
BEFORE UPDATE ON my_table
FOR EACH ROW
WHEN (my_function = 'SOME VALUE')
BEGIN
blah....
END my_trigger;
Everytime I try to compile this, I get an "ORA-4076: invalid NEW or OLD
specification". But I can specify a builtin function, e.g.:
WHEN (SYS_CONTEXT('USERENV','HOST') = 'MYHOST')
I've RTFM'd and tried Metalink as well, but I haven't been able to find
anything that says I can't use a user-defined function here.
Anyone?
