推荐答案

最简单的方法是创建一个存储过程，该存储过程创建一个Transaction，然后同时执行更新和Commits，如果它们都起作用，否则它会回滚到确保数据库完整性.

Google将为您找到很多例子.

Easiest way is to create a Stored Procedure which creates a Transaction, then does both updates and Commits if they both work - otherwise it does a Rollback to ensure DB integrity.

Google will find you many, many examples.

使用所需的输入类型字段创建存储过程，并将数据同时插入两个表中. 例如

Create a stored procedure with desired input type fields and insert the data into both the tables simultaneously.
e.g

CREATE PROCEDURE [dbo].[spMyInsertData]
(@name nvarchar(50), @address nvarchar(max), @emailAddress nvarchar(max), @mobile bigint )
as 
declare @insertQuery nvarchar(max)
Begin
	Begin Try
		set @insertQuery = ''INSERT INTO table1(name,address,emailaddress)
                values(''+@name+'',''+@address+'',''+@emailAddress+'')''
		set @insertQuery = @insertQuery+'' INSERT INTO table2(mobile,EmailAddress)
                values(''+@mobile+'',''+@emailAddress+'')''
		print @insertQuery;
		exec sp_executeSql @insertQuery;
	End Try
	Begin Catch
		print @@error
	End Catch
End
