使用SQL存储过程将我的GUID选择为变量？

Question

我在SQL Server 2008中有一个存储过程,我想将我选择的GUID存储到本地变量中以供进一步使用.我正在尝试如下(以及其他几个变体),但在"@myvars"附近收到语法错误...

DECLARE @myvars uniqueidentifier;
SELECT ID 
INTO @myvars
FROM Device
WHERE DeviceID=@DeviceID

任何帮助表示赞赏.谢谢!

尝试:

DECLARE @myvars uniqueidentifier --declare the local variable to store value in

SELECT @myvars=ID                --assign's the ID column into the variable
FROM Device
WHERE DeviceID=@DeviceID

快速测试:

DECLARE @myvars uniqueidentifier --declare the local variable to store value in
declare @x table (id uniqueidentifier, valueOf varchar(4))

insert @x values (NEWID (),'aa')
insert @x values (NEWID (),'bb')
insert @x values (NEWID (),'cc')

SELECT @myvars=ID                --assign's the ID column into the variable
FROM @x
WHERE valueOf='bb'

SELECT @myvars
select * from @x
