如何将函数结果分配给 SELECT 的 WITH 子句中的名称?
How can I assign a function result to a name in the WITH clause of a SELECT?
如何将函数结果分配给 WITH 子句中的名称?
尝试过:
with
has_perm as ( has_perm(:user) )
select * from my_table where has_perm = 'Y'
这是你想要的吗?
with has_perm as (
select has_perm(:user) as has_perm
from dual
)
select *
from my_table
where 'Y' = (select has_perm from has_perm);
为什么不在没有 CTE 的情况下写这个?
select *
from my_table
where has_perm(:user) = 'Y';
