advice on querying large tables

I have to deal with a new database with a number of tables with 100,000+
records. Can anybody give me any advice on the different methods of
querying large tables as opposed to small tables?
Cheers,
Mike

Learn to use the WHERE clause.
Learn how indexes work (in depth) and then build them appropriately for your
queries. Take a look at the index tuning wizard for additional help there.
Only ask for the data you actually need.
This should get you started..
