while others have said "dynamic sql" -- I'll offer a different approach -- one that is bind variable friendly (no one should be surprised by that by now ;)

http://asktom.oracle.com/pls/ask/f?p=4950:8:::::F4950_P8_DISPLAYID:110612348061

Also, if you do the dynamic sql approach, please add:

execute immediate 'alter session set cursor_sharing=force'; open ref_cursor for query_string;
execute immediate 'alter session set cursor_sharing=exact';

to the code -- to permit bind variables to be used!
