Question

我想编写一个存储过程来循环遍历具有成员资格ID和人员ID详细信息的表，并将其作为变量传递给存储过程。

关于如何做的任何想法。任何帮助都非常感谢。

    DECLARE @membership NUMERIC(9)
DECLARE @person_id NUMERIC(9)
DECLARE @id_num INT 
WHILE (
set @id_num=id_num+1
SELECT membership_id,person_id FROM [dbo].[reb] WHERE id_num <1160


EXEC p_get_details @membership_id, person_id

Answer 1

您有两种选择。第一个是将两个参数传递给过程p_get_details，每个参数都是comma separated string，包含membership_id和person_id列的连接值。

其他方法是将SELECT查询的整个结果集作为Table Valued Parameter传递给过程。

Answer 2

如果你需要一次又一次地为不同的表值调用proc，那么你可以创建一个包含所有成员资格和人员的临时表

请参阅此代码是否适合您： -

DECLARE @membership_id NUMERIC(9)
DECLARE @person_id NUMERIC(9)


if(OBJECT_ID('tempdb..#tempids') is not null)      
drop table #tempids      

SELECT membership_id,person_id
into #tempids
FROM [dbo].[reb]
WHERE id_num <1160

while exists(select 1 from #tempids)
begin
-- select 1 row which will be called by proc

select top 1 @membership_id=membership_id
@person_id =person_id
from #tempids

EXEC p_get_details @membership_id, @person_id

--delete the ids which have been called by proc
delete from #tempids
where 
membership_id=@membership_id
person_id =@person_id


end

while循环获取两个变量到存储过程
