• Alphabetical zip codes. select zip from screwy_address where regexp_substr(zip,'^[A-Z]+$') is not null;
• Zip contains letters select zip from screwy_address where regexp_substr(zip,'[A-Z]+') is not null;
• Zip contains only numbers select zip from screwy_address where regexp_substr(zip,'^\d+$') is not null;

This is fairly unlikely to work with Oracle versions <= 9.2.
