Data comparison between two tables

Hi,

I have a requirement to compare data between two tables in SQL Server.

What is the fastest way to do it using SSIS? There are approx 6~7 millions of records in each table.

My solution: Read both the tables and store the data in Object Type variable. Then run an except query. But I am stuck at except query part. How do I implement it?

Any other solution using SSIS is also welcome which can serve the purpose.

Regards,

Ayush
