optimizing LIKE '%2345' queries

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Is there any way to create a reverse index on string columns so that
queries of the form:

where column like '%2345';

can use an index and perform as fast as searching with like '2345%'?

Is the only way to create a reverse function and create an index using
the reverse function and modify queries to use:

where reverse(column) like reverse('%2345') ?

thanks
