bug number : Bug 5254539
A SQL statement involving a hierarchical query (CONNECT BY)
using cursor statements in the select list may fail with
ORA-600 [qkacon:FJfsrwo]
===================================================================================================
alter system set "_optimizer_cost_based_transformation" = off scope=both;
===================================================================================================
The information in this article applies to:
Oracle Server - Enterprise Edition - Version: 9.2.0.3 - 10.2
This problem can occur on any platform.
Errors ORA 600 internal error code, arguments: [qctcte1],[0],[%s], [%s], [%s],
Symptoms
ORA-00600 [qctcte1] is encountered while performing a nested select which might include functions like distinct or have an order by clause.
Example:
Sql> CREATE OR REPLACE TYPE int_list IS VARRAY(200) OF INTEGER;
Sql> CREATE TABLE test (id INTEGER);
Sql> SELECT id FROM ( SELECT rp.id FROM (SELECT DISTINCT column_value ID FROM
TABLE(int_list(1,1,2))) rp, test p WHERE p.id = 1 ORDER BY p.id DESC)
ERROR at line 2:
ORA-00600: internal error code, arguments: [qctcte1], [0], [], [], [], [], [], []
Cause
An inconsistent datatype is reported during typechecking when parsing a query. This is bug 3557906.
Fix
There are several Workarounds :
1> Remove the desc from the order by clause
Sql > SELECT id FROM ( SELECT rp.id FROM (SELECT DISTINCT column_value ID
FROM TABLE(int_list(1,1,2))) rp, test p WHERE p.id = 1 ORDER BY p.id )
2> Alter session set "_complex_view_merging"=false;
3> Remove the distinct clause
Sql > SELECT id FROM ( SELECT rp.id FROM (SELECT column_value ID FROM TABLE(int_list
(1,1,2))) rp, test p WHERE p.id = 1 ORDER BY p.id DESC)
4> Remove the order by clause
Sql > SELECT id FROM ( SELECT rp.id FROM
(SELECT column_value ID FROM TABLE(int_list(1,1,2))) rp, test p WHERE p.id = 1 )
5> _pred_move_around = false
This is fixed in 10.2 and will be fixed in the 9206 patchset.
