Method Detail

free

public void free()
          throws SQLException
This method will free the internal memory that this object holds.

Specified by:
free in interface Array
Throws:
SQLException

getBaseTypeName

public String getBaseTypeName()
                       throws SQLException
Retrieves the SQL type name of the elements in the array designated by this 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.

Specified by:
getBaseTypeName in interface Array
Returns:
database-specific name for a built-in base type; or the fully-qualified SQL type name for a base type that is a UDT
Throws:
SQLException - if an error occurs while attempting to access the type name

getBaseType

public int getBaseType()
                throws SQLException
Retrieves the JDBC type of the elements in the array designated by this Array object.

Specified by:
getBaseType in interface Array
Returns:
a constant from the class Types that is the type code for the elements in the array designated by this Array object
Throws:
SQLException - if an error occurs while attempting to access the base type

getArray

public Object getArray()
                throws SQLException
Retrieves the contents of the SQL 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.

Specified by:
getArray in interface Array
Returns:
an array in the Java programming language that contains the ordered elements of the SQL ARRAY value designated by this Array object
Throws:
SQLException - if an error occurs while attempting to access the array

getArray

public Object getArray(long index,
                       int count)
                throws SQLException
Retrieves a slice of the SQL 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.

Specified by:
getArray in interface Array
Parameters:
index - the array index of the first element to retrieve; the first element is at index 1
count - the number of successive SQL array elements to retrieve
Returns:
an array containing up to count consecutive elements of the SQL array, beginning with element index
Throws:
SQLException - if an error occurs while attempting to access the array

getResultSet

public ResultSet getResultSet()
                       throws SQLException
Retrieves Array ResultSet that contains the elements of the SQL ARRAY value designated by this Array object. 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.

Specified by:
getResultSet in interface Array
Returns:
an Array ResultSet object containing one row for each of the elements in the array designated by this Array object, with the rows in ascending order based on the indices.
Throws:
SQLException - if an error occurs while attempting to access the array

getResultSet

public ResultSet getResultSet(long index,
                              int count)
                       throws SQLException
Retrieves a result set holding the elements of the subarray that starts at index index and contains up to count successive elements. This method uses the connection's type map to map the elements of the array if the map contains an entry for the base type. Otherwise, the standard mapping is used.

The result set has one row for each element of the SQL array designated by this object, with the first row containing the element at index index. The result set has up to count rows in ascending order based on the indices. Each row has two columns: The second column stores the element value; the first column stores the index into the array for that element.

Specified by:
getResultSet in interface Array
Parameters:
index - the array index of the first element to retrieve; the first element is at index 1
count - the number of successive SQL array elements to retrieve
Returns:
a ResultSet object containing up to count consecutive elements of the SQL array designated by this Array object, starting at index index.
Throws:
SQLException - if an error occurs while attempting to access the array

getArray

public Object getArray(Map map)
                throws SQLException
Retrieves a result set that contains the elements of the SQL 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 getResultSet uses either the given type map or the standard mapping; it never uses the type map associated with the connection.

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.

Specified by:
getArray in interface Array
Parameters:
map - contains the mapping of SQL user-defined types to classes in the Java programming language
Returns:
a ResultSet object containing one row for each of the elements in the array designated by this Array object, with the rows in ascending order based on the indices.
Throws:
SQLException - if an error occurs while attempting to access the array

getArray

public Object getArray(long index,
                       int count,
                       Map map)
                throws SQLException
Retreives a slice of the SQL 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 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.

Specified by:
getArray in interface Array
Parameters:
index - the array index of the first element to retrieve; the first element is at index 1

Returns:
an array containing up to count consecutive elements of the SQL ARRAY value designated by this Array object, beginning with element index
Throws:
SQLException - if an error occurs while attempting to access the array

Retrieves a result set that contains the elements of the SQL 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 getResultSet uses either the given type map or the standard mapping; it never uses the type map associated with the connection.

The result set contains one row for each array element, with two columns in each row.

                       throws SQLException
Retrieves a result set holding the elements of the subarray that starts at index index and contains up to count successive elements. 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 getResultSet uses either the given type map or the standard mapping; it never uses the type map associated with the connection.

The result set has one row for each element of the SQL array designated by this object, with the first row containing the element at index index.

Specified by:
getResultSet in interface Array
Parameters:
