UNION ALL 有 4 张桌子

如何解决UNION ALL 有 4 张桌子

我对 MSSQL 和全栈开发非常陌生，我想用 4 个不同的表执行 UNION ALL 用于贷款储蓄管理系统 以下代码是我对 4 个表的存储过程，我收到错误

消息 207，级别 16，状态 1，程序 USP_GetLoanSavingsDetailsByLoanTakerId，第 13 行 列名“GetSavings”无效。

消息 207，级别 16，状态 1，程序 USP_GetLoanSavingsDetailsByLoanTakerId，第 13 行 无效的列名“GiveSavings”

这是我的代码，我想实现贷款给一个人，贷款从一个人那里收到， 从一个人那里获得的储蓄和在同一天提供给维持交易的人的储蓄 MemberId 是我接受贷款并向其提供储蓄的人，UserId 是希望向会员提供贷款并获得/向同一个人提供储蓄的人

ALTER PROCEDURE [dbo].[USP_GetLoanSavingsDetailsByLoanTakerId]
(
    @MemberId bigint,@UserId bigint
)
AS
BEGIN
    
    --EXEC USP_GetLoanSavingsDetailsByLoanTakerId 5,26


SELECT EntryDate,SUM(LoanGiven) AS LoanGiven,SUM(LoanReceived) AS LoanReceived,SUM(GetSavings) AS GetSavings,SUM(GiveSavings) AS GiveSavings
FROM(  
    SELECT EntryDate,TotalAmount as LoanGiven,0 as LoanReceived
    FROM tblGiveLoan 
    WHERE UserId = @UserId and MemberId = @MemberId
    UNION ALL   
    SELECT EntryDate,0 as LoanGiven,Amount as LoanReceived
    FROM tblReceiveLoan
    WHERE UserId = @UserId and MemberId = @MemberId
    UNION ALL
    SELECT EntryDate,TotalAmount as GetSavings,0 as GiveSavings
    FROM tblGetSavings 
    WHERE UserId = @UserId and MemberId = @MemberId
    UNION ALL   
    SELECT EntryDate,0 as GetSavings,TotalAmount as GiveSavings
    FROM tblGiveSavings
    WHERE UserId = @UserId and MemberId = @MemberId
) t
GROUP BY EntryDate
ORDER BY EntryDate ASC  
 END

解决方法

ALTER PROCEDURE [dbo].[USP_GetLoanSavingsDetailsByLoanTakerId]
(
    @MemberId bigint,@UserId bigint
)
AS
BEGIN
    
    --EXEC USP_GetLoanSavingsDetailsByLoanTakerId 5,26


SELECT EntryDate,SUM(LoanGiven) AS LoanGiven,SUM(LoanReceived) AS LoanReceived,SUM(GetSavings) AS GetSavings,SUM(GiveSavings) AS GiveSavings
FROM(  
        SELECT EntryDate,TotalAmount as LoanGiven,0 as LoanReceived,0 as GetSavings,0 as GiveSavings
        FROM tblGiveLoan 
        WHERE UserId = @UserId and MemberId = @MemberId
    UNION ALL   
        SELECT EntryDate,Amount,0
        FROM tblReceiveLoan
        WHERE UserId = @UserId and MemberId = @MemberId
    UNION ALL
        SELECT EntryDate,TotalAmount,0
        FROM tblGetSavings 
        WHERE UserId = @UserId and MemberId = @MemberId
    UNION ALL   
        SELECT EntryDate,TotalAmount
        FROM tblGiveSavings
        WHERE UserId = @UserId and MemberId = @MemberId
    ) t
GROUP BY EntryDate
ORDER BY EntryDate ASC  
END
