Hi Preetam

Although I can't help you as mysql is not my thing, I also doubt anyone can unless you give them a bit more information e.g. what information are you wanting to fetch?

You can use the Moodle database functions from lib/datalib.php...

Example:

get_record('onetable','field',value);

will return the first record from a table where field = value.

That's because '1' is an unlikely username. If you want to look up by userid, use something like get_record('mdl_user','id',1); or (better still) use some of the builtin functions for getting userdata.

Try experimenting with different functions. Use phpmyadmin to discover which fields are used in Moodle's database. It takes sometime to find out what different functions are for.
