Comment (by felixxm):
🤔 `ORA-24373` cannot be related with the reported issue. If you pass a
trigger statement with trailing `/` , than `_fix_for_params` returns the
same statement as in the ticket description
{{{
>>> from django.db import connection
>>> from django.db.backends.oracle.base import
FormatStylePlaceholderCursor
>>> create_trigger_insert_entry = """
CREATE OR REPLACE TRIGGER UPDATE_BALANCE
AFTER DELETE OR INSERT OR UPDATE OF AMOUNT ON ENTRY
BEGIN
UPDATE ACCOUNT_BALANCE B
SET (B.BALANCE, B.ACCOUNT) = (SELECT SUM(AMOUNT) sum_amount, account
FROM ENTRY e WHERE e.ACCOUNT = B.ACCOUNT
GROUP BY ACCOUNT)
WHERE EXISTS (SELECT 1 FROM ENTRY e WHERE e.ACCOUNT = B.ACCOUNT);
END;
/"""
>>> query, _ =
FormatStylePlaceholderCursor(connection)._fix_for_params(create_trigger_insert_entry,
[])
>>> print(query)
CREATE OR REPLACE TRIGGER UPDATE_BALANCE
AFTER DELETE OR INSERT OR UPDATE OF AMOUNT ON ENTRY
BEGIN
UPDATE ACCOUNT_BALANCE B
SET (B.BALANCE, B.ACCOUNT) = (SELECT SUM(AMOUNT) sum_amount, account
FROM ENTRY e WHERE e.ACCOUNT = B.ACCOUNT
GROUP BY ACCOUNT)
WHERE EXISTS (SELECT 1 FROM ENTRY e WHERE e.ACCOUNT = B.ACCOUNT);
END;
}}}
