34  * A class that maps JDBC types to their corresponding
35  * Java object types, and Java native types. Used
36  * by Column.java to perform object/native mappings.
37  *
38  * These are the official SQL type to Java type mappings.
39  * These don't quite correspond to the way the peer
40  * system works so we'll have to make some adjustments.

42  * -------------------------------------------------------
43  * SQL Type | Java Type | Peer Type
44  * -------------------------------------------------------
45  * CHAR | String | String
46  * VARCHAR | String | String
47  * LONGVARCHAR | String | String
48  * NUMERIC | java.math.BigDecimal | java.math.BigDecimal
49  * DECIMAL | java.math.BigDecimal | java.math.BigDecimal
50  * BIT | boolean OR Boolean | Boolean
51  * TINYINT | byte OR Byte | Byte
52  * SMALLINT | short OR Short | Short
53  * INTEGER | int OR Integer | Integer
54  * BIGINT | long OR Long | Long
55  * REAL | float OR Float | Float
56  * FLOAT | double OR Double | Double
57  * DOUBLE | double OR Double | Double
58  * BINARY | byte[] | ?
