In general, parameter values remain in force for repeated use of a

value. However, in some cases it is useful to immediately release the
resources used by the current parameter values; this can be done by
calling the method clearParameters
.

PreparedStatement
object, which may be any kind of SQL statement. Some prepared statements
return multiple results; the execute
method handles these
complex statements as well as the simpler form of statements handled by
the methods executeQuery
and executeUpdate
.
The execute
method returns a boolean
to
indicate the form of the first result. You must call either the method
getResultSet
or getUpdateCount
to retrieve
the result; you must call getMoreResults
to move to any
subsequent result(s).

object that
will be returned when this PreparedStatement

Because a PreparedStatement
object is precompiled, it is
possible to know about the ResultSet
object that it will
return without having to execute it. Consequently, it is possible to
invoke the method getMetaData
on a
PreparedStatement
object rather than waiting to execute it
and then invoking the ResultSet.getMetaData
method on the
ResultSet
object that is returned.
NOTE: Using this method may be expensive for some drivers due to the lack of underlying DBMS support.

of the method setNull
should be used for user-defined
types and REF type parameters. Examples of user-defined types include:
STRUCT, DISTINCT, JAVA_OBJECT, and named array types.
Note: To be portable, applications must give the SQL type code and the fully-qualified SQL type name when specifying a NULL user-defined or REF parameter. In the case of a user-defined type the name is the type name of the parameter itself. For a REF parameter, the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it. Although it is intended for user-defined and Ref parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-defined or REF type, the given typeName is ignored.

SQLException
- if a database access error occurspublic void setObject(int parameterIndex, Object x) throws SQLException
Sets the value of the designated parameter using the given object. The
second parameter must be of type Object
; therefore, the
java.lang
equivalent objects should be used for built-in
types.
The JDBC specification specifies a standard mapping from Java
Object
types to SQL types. The given argument will be
converted to the corresponding SQL type before being sent to the
database.
Note that this method may be used to pass datatabase- specific abstract
data types, by using a driver-specific Java type. If the object is of a
class implementing the interface SQLData
, the JDBC driver
should call the method SQLData.writeSQL
to write it to the
SQL data stream. If, on the other hand, the object is of a class
implementing Ref
, Blob
, Clob
,
Struct
, or Array
, the driver should pass
it to the database as a value of the corresponding SQL type.
This method throws an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of the interfaces named above.

Sets the value of the designated parameter with the given object. The
second argument must be an object type; for integral values, the
java.lang
equivalent objects should be used.
The given Java object will be converted to the given targetSqlType before
being sent to the database. If the object has a custom mapping (is of a
class implementing the interface SQLData
), the JDBC
driver should call the method SQLData.writeSQL
to write it
to the SQL data stream. If, on the other hand, the object is of a class
implementing Ref

elements of the array that is returned are ordered to
correspond to the commands in the batch, which are ordered according to
the order in which they were added to the batch. The elements in the
array returned by the method executeBatch
may be one of
the following:
SUCCESS_NO_INFO
-- indicates that the
command was processed successfully but that the number of rows affected
is unknown
If one of the commands in a batch update fails to execute properly, this
method throws a BatchUpdateException
, and a JDBC driver
may or may not continue to process the remaining commands in the batch.
However, the driver's behavior must be consistent with a particular DBMS,
either always continuing to process commands or never continuing to
process commands. If the driver continues processing after a failure, the
array returned by the method
BatchUpdateException.getUpdateCounts
will contain as many
elements as there are commands in the batch, and at least one of the
elements will be the following:
EXECUTE_FAILED
-- indicates that the
command failed to execute successfully and occurs only if a driver
continues to process commands after a command fails
A driver is not required to implement this method. The possible
implementations and return values have been modified in the Java 2 SDK,
Standard Edition, version 1.3 to accommodate the option of continuing to
proccess commands in a batch update after a
BatchUpdateException
obejct has been thrown.
