Question

我正面临这个问题，尽管我也设置了@output变量，但我的存储过程始终返回NULL。我想从表中获取最后插入的作用域ID。

有人在我错了的地方帮我吗？

   ALTER PROC spAddOrUpdateMember

     @pMemberId INT =  0 ,
     @pFirstName VARCHAR(50) = 'aa',
     @pLastName VARCHAR(50)='aa' ,
     @pMemberCode VARCHAR(15) = '12312',
     @pDOB DATE = '03/10/2019',
     @pGrade INT = 2 , 
     @pCNIC VARCHAR(14) = '3423434',
     @pFatherName VARCHAR(50) = 'asdasd' , 
     @pCurrentAddress VARCHAR(MAX) = 'asds' , 
     @pPermanentAddress VARCHAR(MAX) = 'fgdf',
     @pEmploymentAddress VARCHAR(MAX) = 'ytuyu' ,
     @pNationality INT =2
     @output int = 0 output    

AS

    BEGIN   
            IF @pMemberId > 0
                BEGIN
                        ---UPDATE ME
                            UPDATE [dbo].[QC_Member_Profile]
                           SET 
                              [FirstName] = @pFirstName
                              ,[LastName] = @pLastName
                              ,[DOB] = @pDOB
                              ,[CNIC] = @pCNIC
                              ,[FatherName] = @pFatherName
                              ,[CurrentAddress] = @pCurrentAddress
                              ,[PermanentAddress] = @pPermanentAddress
                              ,[Nationality] = @pNationality
                              ,[MemberTypeId] =@pMemberTypeId

                         WHERE MemberId  = @pMemberId

                END
            ELSE 
                BEGIN
                    ---INSERT ME
                    INSERT INTO QC_Member_Profile VALUES(
                                                         dbo.PIdentityKey(0),
                                                         @pFirstName,

我猜到了您的ID列的名称，但是应该可以。如果ID列的名称不为MemberID或不具有数据类型int，则需要修改ID列的名称：

ALTER PROC spAddOrUpdateMember @pMemberId int = 0,
                               @pFirstName varchar(50) = 'aa',
                               @pLastName varchar(50) = 'aa',
                               @pMemberCode varchar(15) = '12312',
                               @pDOB date = '03/10/2019',
                               @pGrade int = 2,
                               @pCNIC varchar(14) = '3423434',
                               @pFatherName varchar(50) = 'asdasd',
                               @pCurrentAddress varchar(MAX) = 'asds',
                               @pPermanentAddress varchar(MAX) = 'fgdf',
                               @pEmploymentAddress varchar(MAX) = 'ytuyu',
                               @pNationality int = 2,
                               @output int = 0 OUTPUT
AS
BEGIN
    IF @pMemberId > 0
    BEGIN

        UPDATE [dbo].[QC_Member_Profile]
        SET [FirstName] = @pFirstName,
            [LastName] = @pLastName,
            [DOB] = @pDOB,
            [CNIC] = @pCNIC,
            [FatherName] = @pFatherName,
            [CurrentAddress] = @pCurrentAddress,
            [PermanentAddress] = @pPermanentAddress,
            [Nationality] = @pNationality,
            [MemberTypeId] = @pMemberTypeId
        WHERE MemberId = @pMemberId;

    END;
    ELSE
    BEGIN

        DECLARE @ins table (OutputID int);
        INSERT INTO QC_Member_Profile
        OUTPUT Inserted.MemberID --guessed name
        INTO @Ins
        VALUES (dbo.PIdentityKey(0), @pFirstName, @pLastName, @pDOB, @pCNIC, @pFatherName, @pCurrentAddress, @pPermanentAddress, @pNationality);

        SELECT @output = OutputID 
        FROM @ins;
        SELECT @Output;
    END;


END;

我还修复了您原始问题中的语法错误。

SQL Scope_Identity（）返回空值吗？
