sql - Insert Into 使用 WITH 子句 (CTE) 导致 ORA-00928

Question

我正在尝试做一个本质上非常简单的任务，结果是:

ORA-00928: missing SELECT keyword

我要做的就是将 periods 的结果保存到表 globalTable 中。选择工作正常(我返回行)但是一旦我用 Insert 替换它我就会收到上述错误。

create global temporary table globalTable
(
    ids number(11)
);

with periods as
(
select cl.id uniqueId
from inv_mpan_hh_con_lines cl
left join invoice_vat_lines vl on
                 cl.invoice_id = VL.INVOICE_ID
where rownum < 4
)

--//Issue occurs at insert keyword.  If I comment it and uncomment select it works as expected//--
--select uniqueId
insert into globalTable
from periods;

非常感谢任何指点。

试试这个:

insert into globalTable
with periods as
(
select cl.id uniqueId
from inv_mpan_hh_con_lines cl
left join invoice_vat_lines vl
  on cl.invoice_id = VL.INVOICE_ID
where rownum < 4
)
select uniqueId
  from periods;

CTE (WITH-clause) 是 SELECT 语句的一部分，根据 INSERT 语法，您可以指定值或 SELECT 语句
