String getBaseTypeName() throws SQLException
Array
object.
If the elements are a built-in type, it returns
the database-specific type name of the elements.
If the elements are a user-defined type (UDT),
this method returns the fully-qualified SQL type name.
String
that is the database-specific
name for a built-in base type; or the fully-qualified SQL type
name for a base type that is a UDT
SQLException
- if an error occurs while attempting
to access the type name
SQLFeatureNotSupportedException
- if the JDBC driver does not support
this methodint getBaseType() throws SQLException

object.

the type code for the elements in the array designated by this

this methodObject getArray() throws SQLException
ARRAY
value designated
by this
Array
object in the form of an array in the Java
programming language. This version of the method getArray
uses the type map associated with the connection for customizations of
the type mappings.
Note: When getArray
is used to materialize
a base type that maps to a primitive data type, then it is
implementation-defined whether the array returned is an array of
that primitive data type or an array of Object
.

this methodObject getArray(Map<String,Class<?>> map) throws SQLException
ARRAY
value designated by this
Array
object.
This method uses
the specified map
for type map customizations
unless the base type of the array does not match a user-defined
type in map
, in which case it
uses the standard mapping. This version of the method
getArray
uses either the given type map or the standard mapping;
it never uses the type map associated with the connection.
Note: When getArray
is used to materialize
a base type that maps to a primitive data type, then it is
implementation-defined whether the array returned is an array of
that primitive data type or an array of Object
.
map
- a java.util.Map
object that contains mappings
of SQL type names to classes in the Java programming language
SQLException

- if the JDBC driver does not support
this methodObject getArray(long index, int count) throws SQLException
ARRAY
value designated by this Array
object, beginning with the
specified index
and containing up to count
successive elements of the SQL array. This method uses the type map
associated with the connection for customizations of the type mappings.
Note: When getArray
is used to materialize
a base type that maps to a primitive data type, then it is
implementation-defined whether the array returned is an array of
that primitive data type or an array of Object

ARRAY
value
designated by this Array
object. If appropriate,
the elements of the array are mapped using the connection's type
map; otherwise, the standard mapping is used.
The result set contains one row for each array element, with two columns in each row. The second column stores the element value; the first column stores the index into the array for that element (with the first array element being at index 1). The rows are in ascending order corresponding to the order of the indices.

this methodvoid free() throws SQLException
Array
object and releases the resources that
it holds. The object is invalid once the free
method is called.
After free
has been called, any attempt to invoke a
method other than free
will result in a SQLException
being thrown. If free
is called multiple times, the subsequent
calls to free
are treated as a no-op.
