Returns
true if byte columns are handled as BLOBs
internally. |

materializeObject(CallableStatement cs,
int index,
int type)
Reads an object from a stored procedure OUT parameter, converting it to class
returned by 'getClassName' method.
|

materializeObject(ResultSet rs,
int index,
int type)
Reads an object from JDBC ResultSet column, converting it to class returned by
'getClassName' method.

String |
toString(byte[] value)
Converts value of the supported type to a human-readable String representation.
|
static byte[] |
trimBytes(byte[] bytes)
Strips null bytes from the byte array, returning a potentially smaller
array that contains no trailing zero bytes.
