在不使用输出参数的情况下存储存储过程的结果 [英] Store the result of a stored procedure without using an output parameter

问题描述

我有 2 个存储过程:up_proc1 和 up_proc2.

I have 2 stored procedures: up_proc1 and up_proc2.

这是 up_proc2(的简化版本):

This is (a simplified version of) up_proc2:

CREATE PROCEDURE dbo.up_proc2 
    @id_campaign uniqueidentifier, @id_subcampaign uniqueidentifier, 
    @id_lead uniqueidentifier, @offer NVARCHAR(1000) = NULL
AS  
   SET NOCOUNT ON

   DECLARE @id UNIQUEIDENTIFIER

   SELECT @id = id FROM prospects WHERE id_lead = @id_lead 
        AND id_campaign = @id_campaign AND id_subcampaign = @id_subcampaign
   IF @id IS NULL
   BEGIN
           SET @id = newid ()
           INSERT INTO prospects (id, id_campaign, id_subcampaign, id_lead, offer) 
             values (@id, @id_campaign, @id_subcampaign, @id_lead, @offer)
   END
   ELSE
   BEGIN
           UPDATE prospects set offer = @offer WHERE id=@id
   END

   SELECT @id AS ID
GO

我从 up_proc1 调用 up_proc2.我想要实现的是将 up_proc2 的 @id 存储在 up_proc1 中声明的变量中.这可能不使用输出参数吗?

From up_proc1 I call up_proc2. What I would like to achieve is to store the @id of up_proc2 in a variable declared in up_proc1. Is this possible without using an output parameter?

这是 up_proc1 的样子:

This is how up_proc1 looks like:

CREATE PROCEDURE dbo.up_proc1
AS  
   SET NOCOUNT ON

   DECLARE @fromProc2 UNIQUEIDENTIFIER

   -- NOT WORKING
   -- select @fromProc2 = exec up_insertProspects [snip]

   -- ALSO NOT WORKING
   -- exec @fromProc2 = up_insertProspects [snip]

推荐答案

您可以做的是将输出存储到表变量中:

What you could do is store the output into a table variable:

DECLARE @tmpTable TABLE (ID UNIQUEIDENTIFIER)

INSERT INTO @tmpTable
   EXEC dbo.up_proc2 ..........

然后从那里开始，稍后使用该表变量.

and then go from there and use that table variable later on.
