OrmLite SQL Data Types - Lightweight Java ORM

The following types show the mapping between ORMLite enum, Java types, ResultSet get method, java.sql.Types integer values, ORMLite base database type class, and any overrides that the various databases have. For each of the primitive types, there is also an Object version (ex. BYTE_OBJ) which generates the same SQL but converts to/from Objects.

For more information about the types, see the online docs on the persisted data types. Please contact the author if your database is not included in this list.

I've used the Castor type mapping page a lot during this process. Although I've had to diverge from it once and a while, it's been the best reference I've found.
