通过微软的报表服务器访问Oracle，做好一张报表，为了偷懒，直接在数据库建立了一个视图，然后显示就行了。结果测试时报ORA-600 [qks3tinit]。登陆到本机一运行，没问题啊。怀疑是微软报表服务器连接Oracle的接口有问题。但是其他几个类似视图又都没问题。于是检测SQL：

   SELECT  (CASE
                WHEN fjname IS NULL
                   THEN ''''全局''''
                ELSE fjname
             END) fjname,
            (CASE
                WHEN stat_type IS NULL
                   THEN ''''总计''''
                ELSE stat_type
             END) stat_type,
            (CASE
                WHEN cust_type_old IS NULL
                   THEN ''''总计''''
                ELSE cust_type_old
             END
            ) cust_type_old,
            cnt, curr_user
       FROM (SELECT fjname, stat_type, cust_type_old, COUNT (*) cnt, SUM(CASE state WHEN ''''正常'''' THEN 1 ELSE 0 END) curr_user
                 FROM tmp_tj0507001
                WHERE fjname IS NOT NULL
             GROUP BY grouping sets(rollup(fjname, stat_type, cust_type_old), rollup(stat_type, cust_type_old)))
   ORDER BY fjname, stat_type, cust_type_old;

执行计划：

SELECT STATEMENT, GOAL = HINT: ALL_ROWS   Cost=10 Cardinality=15 Bytes=780
 SORT ORDER BY   Cost=10 Cardinality=15 Bytes=780
  VIEW Object owner=YAOYP  Cost=8 Cardinality=15 Bytes=780 
   TEMP TABLE TRANSFORMATION     
    VIEW Object owner=YAOYP  Cost=8 Cardinality=4 Bytes=208
     VIEW Object owner=YAOYP  Cost=8 Cardinality=4 Bytes=208
      UNION-ALL     
       TABLE ACCESS FULL Object owner=SYS Object name=SYS_TEMP_0FD9D668F_9A864B59 Cost=2 Cardinality=1 Bytes=52
       TABLE ACCESS FULL Object owner=SYS Object name=SYS_TEMP_0FD9D6690_9A864B59 Cost=2 Cardinality=1 Bytes=52
       TABLE ACCESS FULL Object owner=SYS Object name=SYS_TEMP_0FD9D6691_9A864B59 Cost=2 Cardinality=1 Bytes=52
       TABLE ACCESS FULL Object owner=SYS Object name=SYS_TEMP_0FD9D6691_9A864B59 Cost=2 Cardinality=1 Bytes=52
RECURSIVE EXECUTION  Object name=SYS_LE_7_0   
RECURSIVE EXECUTION  Object name=SYS_LE_7_1   
RECURSIVE EXECUTION  Object name=SYS_LE_7_2   
RECURSIVE EXECUTION  Object name=SYS_LE_7_3 

就看到一个TEMP TABLE TRANSFORMATION，这个比较少见哦。另外一个类似SQL：

   SELECT   (CASE
                WHEN fjname IS NULL
                   THEN ''''全局''''
                ELSE fjname
             END) fjname,
            (CASE
                WHEN cust_type IS NULL
                   THEN ''''总计''''
                ELSE cust_type
             END
            ) cust_type,
            curr_user
       FROM (SELECT fjname, (CASE WHEN cust_type IS NULL THEN ''''公免等'''' ELSE cust_type END) cust_type,
                    SUM(CASE state WHEN ''''正常'''' THEN 1 ELSE 0 END) curr_user
               FROM tmp_tj0507001
              WHERE fjname IS NOT NULL AND state = ''''正常''''
              GROUP BY ROLLUP (fjname, (CASE WHEN cust_type IS NULL THEN ''''公免等'''' ELSE cust_type END)))
   ORDER BY fjname, cust_type;

执行计划：

SELECT STATEMENT, GOAL = CHOOSE   Cost=3021 Cardinality=43 Bytes=1376
 SORT ORDER BY   Cost=3021 Cardinality=43 Bytes=1376
  VIEW Object owner=YAOYP  Cost=3020 Cardinality=43 Bytes=1376
   SORT GROUP BY ROLLUP   Cost=3020 Cardinality=43 Bytes=989
    INDEX FAST FULL SCAN Object owner=YAOYP Object name=SYS_IOT_TOP_62350 Cost=367 Cardinality=1132418 Bytes=26045614

没有TEMP TABLE TRANSFORMATION了。看来要避免这个执行路径，想了半天也没办法，开始还怀疑是参数STAR_TRANSFORMATION_ENABLED问题，后来一看是FALSE的。只能到Metalink上找了，结果又是一个Bug，最近简直是一出问题就是Bug，以前怎么就不觉得呢？
