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. If the parameter does not have a user-defined or REF type, the given typeName is ignored.

for integral values, the java.lang equivalent objects should be used.
If the second argument is an InputStream then the stream must contain the number of bytes specified

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,
NClob, Struct, java.net.URL, or Array, the driver should pass
it to the database as a value of the corresponding SQL 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 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, 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
implementing more than one of the interfaces named above.
