Morten,
One solution to this classic "Mutating Table" problem is to
capture the ID (better yet, RowID) of each inserted row in a
public PL/SQL table in an After Row Trigger, then loop
through the PL/SQL table in an After Statement Trigger and
do your Selects and Inserts. Works great.

Hi. I'm indexing the DB with the use of triggers.
In one table, I have a LONG field, I need to read
the :new value of this field in the trigger, modify
it slightly, and insert the value into my context
indexed table.
I'm not allowed to query the table in the trigger
because of mutation, so I cannot do stuff like
CREATE TRIGGER ... ON test_table
FOR EACH ROW
DECLARE
tempContent LONG;
CURSOR selectCursor IS
SELECT long_field FROM test_table WHERE id = :new.id;
BEGIN
OPEN selectCursor;
FETCH selectCursor INTO tempContent;
CLOSE selectCursor;
And I cannot reference the LONG field directly, eg.
:new.long_field,
what can be done? I need to do the equivalent of
BEGIN
INSERT INTO other_table VALUES
('PREFIX'||:new.long_field||'POSTFIX');
END;
In the trigger. Any help greatly appreciated.
Thanks
Morten
