将选择结果作为存储过程的参数传递 [英] Pass select result as parameter of stored procedure

问题描述

我有一个带有以下参数的T-SQL存储过程

I have a T-SQL stored procedure with the following parameters

CREATE PROCEDURE [dbo].[SaveData]
-- Add the parameters for the stored procedure here
    @UserID varchar(50),
    @ServiceID varchar(50),
    @param1 varchar(50),
    @param2 varchar(50),
    @endDate datetime
AS BEGIN
    . 
    .
    -- my code --

我想知道是否可以将select的结果作为参数传递

I want know if it is possible to pass a result of select as parameter:

    exec SaveDate (SELECT player.UserID,player.ServiceID, 'no','no',GETDATE()
           FROM player)

我尝试了类似的方法，但是它不起作用.

I tried something like this, but it does not work.

推荐答案

您在示例中编写的SELECT查询可能会带回多行(您的SELECT不具有WHERE子句或TOP(n)).如果您打算让过程使用一组表格"参数，那么从SQL Server 2008开始，您可以使用表值参数.

The SELECT query you wrote in your example would probably bring back multiple rows (your SELECT does not feature a WHERE clause or a TOP(n)). If your intention is to be able to have your procedure engage a "tabular" set of parameters, from SQL Server 2008, you are able to use table valued parameters.

这涉及到创建用户定义的表表，并且无疑将意味着调整存储过程内部的逻辑.

This involves creating a user defined table table and will almost undoubtedly mean adjusting the logic inside the stored procedure.

希望这会有所帮助:)
