如何檢索並存儲這些指導以備後用？

Question

我具有由

CREATE TABLE Partners ( 
    id UNIQUEIDENTIFIER NOT NULL DEFAULT NEWID(), 
    name NVARCHAR(50) NOT NULL, 
    email NVARCHAR(254) NOT NULL, -- 254 is optimal length according to http://stackoverflow.com/questions/1199190/what-is-the-optimal-length-for-an-email-address-in-a-database 
    PRIMARY KEY (id) 
); 

，並在一個存儲過程一個嘗試用於插入行並返回插入行的id生成的表Partners：

CREATE PROCEDURE AddPartner 
    @name NVARCHAR(50), @email NVARCHAR(254) 
AS 
BEGIN 
    SET NOCOUNT ON 
    INSERT INTO Partners (name,email) 
    OUTPUT INSERTED.id INTO @new_guid 
    VALUES (@name,@email) 
    SELECT @new_guid 
END 

假設我要（1）呼叫AddPartner與(name,email)等於('some dude','dude192@gmail.com）並返回id（稱爲dude_id），這樣我可以在以後插入另一行時使用它：

INSERT INTO Answers (question_id,partner_id,val) VALUES (1,dude_id,24); 

我到底該怎麼做？ （1）和（2）之間會有GO聲明破壞一切嗎？

添加Output Parameter到你的過程

CREATE PROCEDURE Addpartner (@name  NVARCHAR(50), 
          @email NVARCHAR(254), 
          @new_guid UNIQUEIDENTIFIER output) 
AS 
    BEGIN 
     SET NOCOUNT ON 
     INSERT INTO Partners 
        (name,email) 
     OUTPUT INSERTED.id INTO @new_guid 
     VALUES  (@name,@email) 
    END 


DECLARE @new_guid AS UNIQUEIDENTIFIER 

EXEC Addpartner 'some dude', 'dude192@gmail.com', @new_guid output 

INSERT INTO Answers 
      (question_id,partner_id,val) 
VALUES  (@output_identity,'dude_id',24);
