java.lang.Object tyrex.resource.jdbc.xa.TyrexStatementImpl tyrex.resource.jdbc.xa.TyrexPreparedStatementImpl
This class implements java.sql.Statement so that it returned
when prepareStatement is called on TyrexConnection

The reason for this class is for the method java.sql.Statement#getConnection to return the correct connection.
This class is thread safe.

In general, parameter values remain in force for repeated use of a
statement. Setting a parameter value automatically clears its
previous 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
.

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, Blob, Clob, Struct,
or Array, the driver should pass it to the database as a value of the
corresponding SQL type.
Note that this method may be used to pass datatabase- specific abstract data types.

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, then 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.

This version 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.

java.sql.SQLException
- if a database access error occurspublic final void close() throws java.sql.SQLException
Statement

this to happen when it is automatically closed.
It is generally good practice to release resources as soon as
you are finished with them to avoid tying up database
resources.
Note: A Statement
object is automatically closed when it is
garbage collected. When a Statement
object is closed, its current
ResultSet
object, if one exists, is also closed.

This name can then be
used in SQL positioned update/delete statements to identify the
current row in the ResultSet
object generated by this statement. If
the database doesn't support positioned update/delete, this
method is a noop. To insure that a cursor has the proper isolation
level to support updates, the cursor's SELECT
statement should be
of the form 'select for update ...'. If the 'for update' phrase is
omitted, positioned updates may fail.
Note: By definition, positioned update/delete
execution must be done by a different Statement
object than the one
which generated the ResultSet
object being used for positioning. Also,
cursor names must be unique within a connection.

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:
-2
-- 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:
-3
-- 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.
