I want to retrieve over 20 millions of record from SQL server database. Query which is written in existing project is taking 10-15 minutes to generate output. I want to achieve it in few seconds.
So is there any way or query to achieve that?? or what else i have to do in database so that i can get all the records as fast as possible.

Have you any idea what you are going to do with 20 million records? Display them on the screen for some poor user to try and find the one item he/she is interested in?

20 Million records are surely larger than 1 Gigbyte (that's merely 50 bytes per record - do you think such a low number is enough)? Who has such a fast internet connection (look at the tag: ASP.NET) to transfer that within a few seconds? Hardly a company has a Gigabit network internally.
