Array
class provides static methods to dynamically create and access Java arrays. Array
permits widening conversions to occur during a get or set operation, but throws an IllegalArgumentException
if a narrowing conversion would occur.

ARRAY
. By default, an Array
value is a transaction-duration reference to an SQL ARRAY
value. By default, an Array
object is implemented using an SQL LOCATOR(array) internally, which means that an Array
object contains a logical pointer to the data in the SQL ARRAY
value rather than containing the ARRAY
value's data. The Array
interface provides methods for bringing an SQL ARRAY
value's data to the client as either an array or a ResultSet
object. If the elements of the SQL ARRAY
are a UDT, they may be custom mapped. To create a custom mapping, a programmer must do two things:
Class
object for the class implementing SQLData
When a type map with an entry for the base type is supplied to the methods getArray
and getResultSet
, the mapping it contains will be used to map the elements of the ARRAY
value. If no type map is supplied, which would typically be the case, the connection's type map is used by default. If the connection's type map or a type map supplied to a method has no entry for the base type, the elements are mapped according to the standard mapping.
All methods on the Array
interface must be fully implemented if the JDBC driver supports the data type.
