MySql and Oracle Data Type Mappings

the default settings used by SQL Developer to convert data types from MySQL to Oracle. SQL Developer enables you to 

change the default setting for certain data types by specifying an alternative type. For information about changing the default data type mappings, see the SQL Developer online help.
