We need to find the names of columns (table metadata) that have particular values.
"select * from table where anycolumn like/equal newyork"
and then see the column definition/name where it occurs.
Kindly let us know whether it is possible

do you mean to say you want to say "select * from table where

definition/name where it occurs ?
