sql - 如何在 SQL 中组合 WITH 语句和 INSERT INTO

Question

我有一个带有 with 子句的 sql 语句，我想用 insert into 将结果写入一个表中。我尝试过的 with 和 insert into 的任何组合都会给我一条错误消息。我想做的最小例子：

create table temp as (quarter decimal(5));

insert into temp (
with bla as (select 2021 as year from dummy)
select 10*year + 1 as quarter from bla
) 

将 with 语句放在 insert into 之外也不起作用。

对于 Oracle，您需要以下语法：

insert into temp (quarter)
with bla (year) as (
  select 2021 as year from dual
)
select 10*year + 1 as quarter from bla;

你的CREATE TABLE陈述应该是：

create table temp (quarter decimal(5));
