查看trace中的信息

根据MOS 中的信息,和当前的数据库版本是10201

With the stack trace:
qkssaOptdef2Struct <- qkssaSamplePushdown <- qkaMarkQkn <- qkaMarkQkn <- qkadrv2Pre <- qkadrv2 <- opitca 可以确认是bug 5005939

This causes ORA-600 [qkssa02S1] when running a query against a table with a functional index which contains a constant.

查询trace 中指定表的索引情况

SQL> select index_name,index_type from USER_INDEXES WHERE LOWER(TABLE_NAME)='icme_noproject_score';
INDEX_NAME                     INDEX_TYPE
------------------------------ ---------------------------
UK_NOPROJECT_SCORE             NORMAL
...
IDX_NOPROJECT_SCORE_SPECID     NORMAL
IDX_CNT                        FUNCTION-BASED NORMAL
IDX_ACTIVITY_DATE              NORMAL
IDX_I_NOPROJECT_SCORE_SAC      NORMAL

SQL> set long 1000
SQL> select dbms_metadata.get_ddl('INDEX','IDX_CNT') FROM DUAL;
DBMS_METADATA.GET_DDL('INDEX','IDX_CNT')
--------------------------------------------------------------------------------
  CREATE INDEX "ICME5"."IDX_CNT" ON "ICME5"."ICME_NOPROJECT_SCORE" (1)

想起这个索引是昨天为了select count(*) tablexx 而建的一个function-index,没想到在此版本还触发了bug,在10203版本中已修复。
