Question

我有以下查询，但无效

with mag_re as(
    select a as "A", b as "B"
    from table1 
    where 'condition'

    union all

    select a as "A", b as "B"
    from table2
    where 'condition'
)
select t.a as "A", t.b as "B", M.b as "BB"
from table3 t, mag_re M
where t.a = M.A

union all

select t.a as "A", t.b as "B", M.b as "BB"
from table4 t, mag_re M
where t.a = M.A

它不起作用，我的查询与上面相同。我只想运行一些查询并存储到该动态表中。通过使用该动态表，我想获得一些数据。

您发布的真实代码并未执行原始简化代码所显示的内容。你实际上做的更像是：

with mag_re as(
    select a as "A", b as "B"
    from table1 
    where 'condition' = 'x'
    union all
    select a as "A", b as "B"
    from table2
    where 'condition' = 'x'
)
select t.a as "A", t.b as "B", M.b as "BB"
from table3 t, mag_re M
where t.a = M.A
union all
with mag_re as(
    select a as "A", b as "B"
    from table1 
    where 'condition' = 'x'
    union all
    select a as "A", b as "B"
    from table2
    where 'condition' = 'x'
)
select t.a as "A", t.b as "B", M.b as "BB"
from table4 t, mag_re M
where t.a = M.A;

SQL Error: ORA-32034: unsupported use of WITH clause
32034. 00000 -  "unsupported use of WITH clause"
*Cause:    Inproper use of WITH clause because one of the following two reasons
           1. nesting of WITH clause within WITH clause not supported yet
           2. For a set query, WITH clause can't be specified for a branch.
           3. WITH clause cannot be specified within parenthesis.
*Action:   correct query and retry

您在主联盟的每一半中重复了with子句，这是不正确的并且导致错误。子查询因子分解的一部分是阻止你重复代码。所以（具有讽刺意味）你的初始简化代码实际上很好，因为with 不重复：

with mag_re as(
    select a as "A", b as "B"
    from table1 
    where 'condition' = 'x'
    union all
    select a as "A", b as "B"
    from table2
    where 'condition' = 'x'
)
select t.a as "A", t.b as "B", M.b as "BB"
from table3 t, mag_re M
where t.a = M.A
union all
select t.a as "A", t.b as "B", M.b as "BB"
from table4 t, mag_re M
where t.a = M.A;

对于您的真实代码，只需删除第二个with子句：

使用union的SQL查询中的动态表
