数据库链接执行含ROLLUP的SQL的Bug

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？

55不过我还是觉得是  TEMP TABLE TRANSFORMATION  问题，没理由第2个SQL里的ROLLUP就没问题哦。唉，放弃ROLLUP咯。关于上面这个执行路径资料好少，有办法避免么？</bug:2419335></bug:2836690>
