If you want to use LIKE 'abc%' type queries with indexes you need to declare your index like this: CREATE INDEX myindex ON mytable(myfield text_pattern_ops); This changes the ordering so LIKE queries work, doesn't matter what locale. > => Does this mean that through JDBC I can not use ANSI_SQL implying I > can not use indexes in 'LIKE' queries?
