选择并设置多个vars sql 2008

Question

如何在insert语句之前设置多个值？以下不起作用。

declare @foo int
declare @bar int
set (select @foo=foo, @bar=bar from Foobar where id=123);

insert into ...
select @foo, 3, @bar

Answer 1

使用此 -

declare @foo int
declare @bar int
select @foo=foo, @bar=bar from Foobar where id=123;

insert into ...
select @foo, 3, @bar

Answer 2

您可以使用SELECT：

分配变量

select @foo=foo, @bar=bar from Foobar where id=123;

或者，只需跳过变量并合并SELECT and INSERT：

insert into ...
select foo, bar
from Foobar
where id = 123;
