我创建了一个在 select 子句中有不同的视图。
当我尝试使用“select * from view”选择所有记录时,出现以下错误:
ORA-01446: cannot select ROWID from view with DISTINCT, GROUP BY, etc.
我正在寻找为什么会发生这种情况并得出了这个结论:
您试图创建一个在 SELECT 语句中包含 ROWID 以及 DISTINCT 或 GROUP BY 等子句的视图。这是不允许的。参考
这很尴尬,因为视图中的 select 语句没有选择 rowid,并且没有在任何其他子句(where、order 等)中使用。
对此有任何想法吗?
更新
我无法发布查询本身,但我发布了一个类似的。这里是:
SELECT DISTINCT t1.c1 TABLE1_C1,
t1.c2 TABLE1_C2,
t1.c3 TABLE1_C3,
t1.c4 TABLE1_C4,
t1.c4 TABLE1_C4,
t1.c5 TABLE1_C5,
t1.c6 TABLE1_C6,
t1.c7 TABLE1_C7,
t1.c8 TABLE1_C8,
t2.c1 TABLE2_C1,
t2.c2 TABLE2_C2,
t2.c3 TABLE2_C3,
t2.c4 TABLE2_C4,
t2.c5 TABLE2_C5,
t3.c1 TABLE3_C1,
t2.c6 TABLE2_C6,
t4.c1 TABLE4_C1,
t4.c2 TABLE4_C2,
t4.c3 TABLE4_C3
FROM table1 t1
LEFT JOIN table2 t2
ON t1.c1 = t2.c7
left JOIN table4 t4
ON t4.c4 = t2.c1
LEFT JOIN table3 t3
ON (t2.c1 = t3.c2
AND t2.c8 = t3.c3
AND t2.c9 = t3.c4)
WHERE (t2.cp5 = 0 or t2.cp5 is null)
AND (t2.c3 =
(SELECT MAX(c3)
FROM table2 s_t2
WHERE s_t2.c3 LIKE t2.c3
AND s_t2.c7 = t1.c1
) or t2.c3 is null)
