Parttern matching in mnesia

[Vladimir Ulogov]

Hello folks,
Can somebody submit the samples for strings lookup in the mnesia table
which will perform similar to 'LIKE' operator in SQL. Another word, how
to construct operator like 'SELECT * FROM table WHERE str_field LIKE
"%abc%' (lookup all str_filed which _contain_ "abc") using
Mnesia/Mnemosyne
