Also, a select count(*) on this table returns 32104 rows, i.e. select count(*) from DataIndex where searchKey like 'a%' - gives 32104 as its result Am I doing something wrong here? Given that the searched column is indexed, shouldn't it examine way less rows? LIKE does not benefit from keys! signature.asc Description: OpenPGP digital signature

It does if the wildcard is not at the front, as indicated at http://dev.mysql.com/tech-resources/presentations/presentation-oscon2000-2719/ ... *When MySQL uses indexes* ... When you use a LIKE that doesn't start with a wildcard. SELECT * FROM table_name WHERE key_part1 LIKE 'jani%' ... PB -
