Interface Struct

public interface Struct

JDBC 2.0

The standard mapping for an SQL structured type. A Struct object contains a value for each attribute of the SQL structured type that it represents. By default, an instance ofStruct is valid as long as the application has a reference to it.

Method Summary

Object[]	getAttributes() Produces the ordered values of the attributes of the SQL structurec type that this Struct object represents.
Object[]	getAttributes(Map map) Produces the ordered values of the attributes of the SQL structurec type that this Struct object represents.
String	getSQLTypeName() Retrieves the SQL type name of the SQL structured type that this Struct object represents.

Method Detail

getSQLTypeName

public String getSQLTypeName()
                      throws SQLException

Retrieves the SQL type name of the SQL structured type that this Struct object represents.

Throws:

SQLException - if a database access error occurs

getAttributes

public Object[] getAttributes()
                       throws SQLException

Produces the ordered values of the attributes of the SQL structurec type that this Struct object represents. This method uses the type map associated with the connection for customizations of the type mappings. If there is no entry in the connection's type map that matches the structured type that this Struct object represents, the driver uses the standard mapping.

Conceptually, this method calls the method getObject on each attribute of the structured type and returns a Java array containing the result.

Returns:

an array containing the ordered attribute values

Throws:

SQLException - if a database access error occurs

getAttributes

public Object[] getAttributes(Map map)
                       throws SQLException

Produces the ordered values of the attributes of the SQL structurec type that this Struct object represents. This method uses the given type map for customizations of the type mappings. If there is no entry in the given type map that matches the structured type that this Struct object represents, the driver uses the standard mapping.

Conceptually, this method calls the method getObject on each attribute of the structured type and returns a Java array containing the result.

Parameters:

map - a mapping of SQL type names to Java classes

Returns:

an array containing the ordered attribute values

Throws:

SQLException - if a database access error occurs
