Oracle Create trigger statement fails with internal error code ORA-00600

oracle, sql, triggers

Solution

Found a solution that worked. Surround the block of code with the following ALTER statements:

ALTER SESSION SET PLSCOPE_SETTINGS = 'IDENTIFIERS:NONE';

... sql statements here ...

ALTER SESSION SET PLSCOPE_SETTINGS = 'IDENTIFIERS:ALL'; 

For some reason, the Oracle database dump does not include these commands, but this fixed the problem.

Problem

Trying to execute a dumpfile created from Oracle. Everything gets created and altered fine until this block: ``` CREATE OR REPLACE TRIGGER "LABS"."CHANNEL_CHANNEL_ID_TRG" BEFORE INSERT ON channel FOR EACH ROW DECLARE v_newVal NUMBER(12) := 0; v_incval NUMBER(12) := 0; BEGIN IF INSERTING AND :new.CHANNEL_ID IS NULL THEN SELECT channel_CHANNEL_ID_SEQ.NEXTVAL INTO v_newVal FROM DUAL; -- If this is the first time this table have been inserted into (sequence == 1) IF v_newVal = 1 THEN --get the max indentity value from the table SELECT NVL(max(CHANNEL_ID),0) INTO v_newVal FROM channel; v_newVal := v_newVal + 1; --set the sequence to that value LOOP EXIT WHEN v_incval>=v_newVal; SELECT channel_CHANNEL_ID_SEQ.nextval INTO v_incval FROM dual; END LOOP; END IF; --used to emulate LAST_INSERT_ID() --mysql_utilities.identity := v_newVal; -- assign the value from the sequence to emulate the identity column :new.CHANNEL_ID := v_newVal; END IF; END; ``` This fails and severs the connection, giving the following rather cryptic error: ``` ORA-00603: ORACLE server session terminated by fatal error ORA-00600: internal error code, arguments: [kqlidchg1], [], [], [], [], [], [], [], [], [], [], [] ORA-00604: error occurred at recursive SQL level 1 ORA-00001: unique constraint (SYS.I_PLSCOPE_SIG_IDENTIFIER$) violated 00603. 00000 - "ORACLE server session terminated by fatal error" *Cause: An ORACLE server session is in an unrecoverable state. *Action: Login to ORACLE again so a new server session will be create ```
