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:

to send it via a java.io.Reader object. The data will be read from the stream as needed until
end-of-file is reached. The JDBC driver will do any necessary conversion from UNICODE to the database char
format.
Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

ResultSetMetaData object that contains information about the columns of the
ResultSet object that will be returned when this PreparedStatement object is executed.
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.

NULL. 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.

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.

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 interfaceSQLData, 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, NClob,
Struct, java.net.URL, RowId, SQLXML or Array,
the driver should pass it to the database as a value of the corresponding SQL type.
Note: Not all databases allow for a non-typed Null to be sent to the backend. For maximum portability, the
setNull or the setObject(int parameterIndex, Object x, int sqlType) method should be
used instead of setObject(int parameterIndex, Object x).
Note: This method throws an exception if there is an ambiguity, for example, if the object is of a class
