How to store historical records in a history table in SQL Server

Question

I have 2 tables, Table-A and Table-A-History.

• Table-A contains current data rows.
• Table-A-History c

Answer 1

You can simply create procedure or job to overcome this issue like this:

 create procedure [dbo].[sp_LoadNewData]
 AS
INSERT INTO [dbo].[Table-A-History]
 (
 [1.Column Name], [2.Column Name], [3.Column Name], [4.Column Name]
 )    
 SELECT [1.Column Name], [2.Column Name], [3.Column Name], [4.Column Name]
 FROM dbo.[Table-A] S

 WHERE NOT EXISTS
 (
 SELECT  * FROM [dbo].[Table-A-History] D WHERE D.[1.Column Name] =S.[1.Column Name]
 )

Note: [1.Column Name] is common column for the tables.
