    Method
    Description
    protected Hashtable
    Return the mapping of class types to database types for the schema framework.
    INTERNAL We support more primitive than JDBC does so we must do conversion before printing or binding.
    int
    INTERNAL: returns the maximum number of characters that can be used in a field name on this platform.
    Most database support a syntax.
    boolean
     
    Builds a table of minimum numeric values keyed on java class.
    Builds a table of minimum numeric values keyed on java class.
    void
    Append the receiver's field 'NOT NULL' constraint clause to a writer.

    setParameterValueInDatabaseCall(Object parameter, CallableStatement statement, String name, org.eclipse.persistence.internal.sessions.AbstractSession session)
    INTERNAL: DBase does not support Time/Timestamp so we must map to strings.
