Question

我需要一些帮助，我对SQL有点新手。我有一个存储过程，从另一个应用程序作为智能对象执行。更改之前的代码看起来像第1节中的代码。我根据第2节更改了代码，以便存储过程首先查看Sales ID类型实际上是3与存储过程的表成员资格中的成员资格数比较然后在members表中执行相同的操作。如果查询是3，其中包含会员编号，我希望它在成员表中使用到期日期而不是

部分

SELECT @ExpiryDate = DATEADD（YEAR，1，DATEADD（d，-1，DATEADD（m，0，@ ManagingDate）））

该woudl将364天添加到当前日期

Answer 1

请尝试这样做，因为您没有包含所有列，因此很难完成此答案。

   SELECT @ExpiryDate = M.MembershipExpiry From Memberships M WHERE M.MembershipNumber = @MembershipNumber AND M.SalesTypeId = 3 AND M.[Enabled] =1

        IF @ExpiryDate IS NULL
        BEGIN
           SELECT @ExpiryDate = DATEADD(YEAR, 1, DATEADD(d, -1, DATEADD(m, 0, @CreatedDate)))
        end

Answer 2

将代码更改为

BEGIN SELECT @ExpiryDate = MembershipExpiry来自会员M WHERE M.MembershipNumber = @MembershipNumber
成员资格MS WHERE M.MembershipNumber = @MembershipNumber AND SalesTypeId = 3 AND MS。[Enabled] = 1

    IF @ExpiryDate IS NULL
            SELECT @ExpiryDate = DATEADD(YEAR, 1, DATEADD(d, -1, DATEADD(m, 0, @CreatedDate)))
END

使用IF的存储过程
