java.sql.Struct |
Known Indirect Subclasses |
The standard mapping in the Java programming language 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.
All methods on the Struct
interface must be fully implemented if the
JDBC driver supports the data type.
Public Methods | |||||||||||

Produces the ordered values of the attributes of the SQL

Produces the ordered values of the attributes of the SQL

Struct object represents. | |||||||||||
Retrieves the SQL type name of the SQL structured type
that this
Struct object represents. |
Produces the ordered values of the attributes of the SQL
structured type that this Struct
object represents.
As individual attributes are processed, 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 an attribute 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.

SQLFeatureNotSupportedException | if the JDBC driver does not support this method |
Produces the ordered values of the attributes of the SQL
structured type that this Struct
object represents.
As individual attrbutes are proccessed, 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 an attribute represents,
the driver uses the standard mapping. This method never
uses the type map associated with the connection.
Conceptually, this method calls the method
getObject
on each attribute
of the structured type and returns a Java array containing
the result.
