What are you trying to get? Column values or (TABLE,COLUMN) combination? You could probably use a function like this:
create or replace function trickery(T varchar2,C varchar2, V number) return number deterministic as qry varchar2(2048); cnt number:=0; begin qry='select count(*) from '||T||' where '||C||'='||V; execute immediate qry into cnt; return(cnt); end; /
The rest is simply using this function in a query against dba_tab_columns.
