i just need to use stars only?no need to give the table name....it'll automatically fetch records from all tables??????

yes.it will check all the columns of all the tables of any database

SELECT * FROM * WHERE * LIKE '%your_search_string%'

first * is for all the fields
second for all the tables
third for all the columns of the tables on which you want to apply search criteria. In other words, it will give you results from all the database. Try it.

Cheers
