想要多次调用过程并从查询中发送值作为参数

Question

伙计我想多次调用一个过程，输出多个行值作为过程的参数。我的查询是这样的：

select RoomID from tbWalkInRooms where WID =@ID

现在这个查询正在返回多个roomid，我每次都必须发送一个不同的roomid作为参数。

Answer 1

我理解你的问题，你可以通过使用游标来实现：

declare @room_id int

declare room_id_cursor cursor for select RoomID from tbWalkInRooms where WID =@ID
open room_id_cursor
fetch next from room_id_cursor into @room_id
while @@fetch_status = 0
begin
  exec your_procedure @room_id
  fetch next from room_id_cursor into @room_id
end
close room_id_cursor
deallocate room_id_cursor
