What are some examples of Signed Data types in Oracle? Anyone know ? because there is a field in a table in my database that is called Base-Pay and the type is "SIGNED" so I really dunno what would go in there . Is that just a type for decimals ?

Don't think there is a PL/SQL data type that's just called "signed". What tool are you using to look at table schema?
