在SQL中插入表A时如何更新表B的一列

Question

我有两个表 Tbl_Appointment 和 Tbl_AppointmentRequest。 Tbl_AppointmentRequest 中的数据来自移动应用程序，在 UI 中有一个按钮批准，单击它会用 Tbl_AppointmentRequest 的数据填充文本框、下拉列表等，然后有一个称为提交的按钮，当我提交它时，它会将数据插入 Tbl_Appointment 并插入时Tbl_AppointmentRequest 中有一个列 isappconfirm 应该更新为 1。 以下是我的查询，我可以插入但无法将 isappconfirm 列更新为 1。

ALTER Proc [dbo].[Sp_Save_Appointment]
(@AppointmentID nvarchar(50),
@PatientID nvarchar(50),
@PatientName nvarchar(500),
--@PackageID nvarchar(50),
@PackageName nvarchar(500),
@Date nvarchar(50),
@Time nvarchar(50),
@DoctorID nvarchar(50),
@DoctorName nvarchar(500),
@HospitalName nvarchar(500),
@Address nvarchar(500),
@Price nvarchar(500),
@Latitude nvarchar(50),
@Longitude nvarchar(50),
@EscortName nvarchar(500),
@Createdby nvarchar(50),
@CreatedbyName nvarchar(500),
@Modifiedby nvarchar(50),
@ModifiedbyName nvarchar(500))
as begin
if(@AppointmentID='')
begin
Insert into Tbl_Appointment(PatientID,PatientName,PackageName,Date,Time,DoctorID,DoctorName,HospitalName,
Address,Price,Latitude,Longitude,EscortName,Createdby,CreatedbyName,CreatedDate)
values(@PatientID,(Select Top(1)PatientName from Tbl_Patientinfo where PatientID=@PatientID),
@PackageName,
@Date,@Time,@DoctorID,(Select Top(1) DoctorName from Tbl_DoctorInfo where DoctorID=@DoctorID),
@HospitalName,@Address,@Price,@Latitude,@Longitude,@EscortName,
@Createdby,(Select Top(1)UserName from Tbl_UserInfo where UserId=@Createdby),
convert(datetime,SWITCHOFFSET(SYSDATETIMEOFFSET(), '+05:30')))
Declare @id nvarchar(20) set @id=@@identity
select @id as message
end

else
begin
Update Tbl_Appointment Set PatientID=@PatientID,@PatientName=(Select Top(1)PatientName from Tbl_Patientinfo where PatientID=@PatientID),
PackageName=@PackageName,
Date=@Date,Time=@Time,DoctorID=@DoctorID,DoctorName=(Select Top(1) DoctorName from Tbl_DoctorInfo where DoctorID=@DoctorID),

Modifiedby=@Modifiedby,ModifiedbyName=@ModifiedbyName,ModifiedDate=convert(datetime,SWITCHOFFSET(SYSDATETIMEOFFSET(), '+05:30'))
Where AppointmentID=@AppointmentID
Select '1' as message

declare @isappconfirm nvarchar(50)
set @isappconfirm=(select top(1) isappconfirm from Tbl_AppointmentRequest where AppointmentReqID=@AppointmentID order by AppointmentReqID desc)
if(@isappconfirm='')
begin
update Tbl_AppointmentRequest set isappconfirm='1' where AppointmentReqID=@AppointmentID
end


end
end

Answer 1

您正在 Tbl_Appointment 中插入数据。

所以，您将获得在 Tbl_AppointmentRequest 中不可用的新身份密钥（new AppointmentID）。 这就是为什么这不起作用。

为此，您还必须在 Tbl_AppointmentRequest 上添加与 inserted AppointmentID 相关的 new entry 并设置 isappconfirm=1强>。 因此，新条目将在 Tbl_AppointmentRequest 中添加 isappconfirm=1 插入。 就是这样。

Answer 2

我很惊讶人们为什么无法回答如此简单的问题，并在他们无法回答并为错误答案投票时指出和反对投票。

这很简单只需传递@AppointmentReqID 并在声明@isappconfirm 然后在哪里条件AppointmentReqID=@AppointmentReqID

ALTER Proc [dbo].[Sp_Save_AppointmentRequest]

@PatientID nvarchar(50),
@PatientName nvarchar(500),

@DoctorName nvarchar(500),
@HospitalName nvarchar(500),
@Address nvarchar(500),
@Price nvarchar(500),
@Latitude nvarchar(50),
@Longitude nvarchar(50),
@EscortName nvarchar(500),
@Createdby nvarchar(50),
@CreatedbyName nvarchar(500),
@Modifiedby nvarchar(50),
@ModifiedbyName nvarchar(500),
@AppointmentReqID nvarchar(50))
as begin
if(@AppointmentID='')
begin


Insert into Tbl_Appointment(PatientID,PatientName,PackageName,Date,Time,DoctorID,DoctorName,HospitalName,
Address,Price,Latitude,Longitude,EscortName,Createdby,CreatedbyName,CreatedDate)

@Createdby,(Select Top(1)UserName from Tbl_UserInfo where UserId=@Createdby),
convert(datetime,SWITCHOFFSET(SYSDATETIMEOFFSET(), '+05:30')))
Declare @id nvarchar(20) set @id=@@identity



declare @isappconfirm nvarchar(50)
set @isappconfirm=(select top(1) isappconfirm from Tbl_AppointmentRequest where AppointmentReqID=@AppointmentReqID order by AppointmentReqID desc)
if(@isappconfirm='NULL')
begin
update Tbl_AppointmentRequest set isappconfirm='1' where AppointmentReqID=@AppointmentReqID
end
select @id as message
end

else
begin

Update Tbl_Appointment Set PatientID=@PatientID,@PatientName=(Select Top(1)PatientName from Tbl_Patientinfo where PatientID=@PatientID),

Select '1' as message


end
