以表格形式获取多选查询值答案

【问题描述】：

我正在使用一个存储过程，其中我使用了多个 select 语句，但是这些语句将值作为多个结果集返回，但我希望在单个结果集中返回值。

这是我的程序：

Create Proc GetRequestDetail
As
Begin
    Select Count(ReceiverId) As GetInvitation 
    From Requests 
    Where ReceiverId = 1044 

    Select Count(SenderId) As GetSendInvitation 
    From Requests 
    Where SenderId = 10

    Select Count(ID) As GetAcceptedRequest 
    From Requests 
    Where ReceiverId = 7 And Status = 2735

    Select Count(ID) As GetRejectedRequest 
    From Requests 
    Where ReceiverId = 2182 And Status = 2736

    Select Count(ID) As GetAcceptRequest 
    From Requests 
    Where SenderId = 10 And status = 1255

    Select Count(ID) As GetrejectRequest 
    From Requests 
    Where SenderId = 10 And status = 1256
end

【解决方案1】：

如果所有结果都需要在同一行：

ALTER PROCEDURE GetRequestDetail
as
begin

    SELECT
        GetInvitation = (Select Count(ReceiverId)  from Requests Where ReceiverId = 1044 ),
        GetSendInvitation = (Select Count(SenderId)  from Requests Where SenderId = 10),
        GetAcceptedRequest = (Select Count(ID)  from Requests where ReceiverId = 7 and Status = 2735),
        GetRejectedRequest = (Select Count(ID) as GetRejectedRequest from Requests where ReceiverId = 2182 and Status = 2736),
        GetAcceptRequest = (Select Count(ID) as GetAcceptRequest from Requests where SenderId = 10 and status = 1255),
        GetrejectRequest = (Select Count(ID) as GetrejectRequest from Requests where SenderId = 10 and status = 1256)

end

附带说明，您似乎缺少 SP 的参数（可能接收搜索到的 ID 作为参数？）。可能类似于以下内容：

ALTER PROCEDURE GetRequestDetail
    @ReceivedID INT,
    @SenderID INT
as
begin

    SELECT
        GetInvitation = (Select Count(ReceiverId)  from Requests Where ReceiverId = @ReceivedID ),
        GetSendInvitation = (Select Count(SenderId)  from Requests Where SenderId = @SenderID),
        GetAcceptedRequest = (Select Count(ID)  from Requests where ReceiverId = @ReceivedID and Status = 2735),
        GetRejectedRequest = (Select Count(ID) as GetRejectedRequest from Requests where ReceiverId = @ReceivedID and Status = 2736),
        GetAcceptRequest = (Select Count(ID) as GetAcceptRequest from Requests where SenderId = @SenderID and status = 1255),
        GetrejectRequest = (Select Count(ID) as GetrejectRequest from Requests where SenderId = @SenderID and status = 1256)

end
