Hi Shubham, I had similar requirement long back. if you are dealing with large data then i would suggest you to create a stored proc to handle all db tasks like update , insert and delete.

Thanks Naresh, Do you have sample query to compare data from two tables. This would be really helpful.

Hi,

First you need to save this date in temp staging table, then you need to query staging table and your transitional table and compare your data with your transactional table before writing. If the data already exist do wrote this data to transactional table other wise write to your table.

Note: After you process your date delete data from staging table since you no longer need that data
