【中文标题】UNION ALL 有 4 张桌子【英文标题】:UNION ALL with 4 tables 【发布时间】:2020-12-30 05:23:12 【问题描述】: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 下面的代码是我有 4 个表的存储过程,我得到了错误
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 列名“GiveSavings”无效
这是我的代码,我想实现 Loan Give to a person, Loan Received from a person,
从某人那里获得的储蓄和给予在同一天进行交易的人的储蓄
MemberId
是我要贷款并将储蓄提供给的人,UserId
是希望将贷款提供给会员并获得/提供储蓄给同一个人的人
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
【问题讨论】:
错误消息声称您使用的是 MS SQL aka SQL Server,而不是 mysql。该问题已重新标记。 我遇到错误在 UNION 中,输出行集的名称取自第一个子查询,所有其他子查询的名称/别名都被忽略。 请确认是MySQL还是SQL Server,并相应更新您的问题(第一句和标签)。 它是 SQL Server @Akina 我还有一个问题你能帮我吗? ***.com/questions/65918586/… 【参考方案1】:ALTER PROCEDURE [dbo].[USP_GetLoanSavingsDetailsByLoanTakerId]
