Sets the designated parameter to a Reader object. The reader must contain the number of characters specified by length otherwise a SQLException will be generated when the PreparedStatement is executed. This method differs from the setCharacterStream (int, Reader, int) method because it informs the driver that the parameter value should be sent to the server as a CLOB. When the setCharacterStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGVARCHAR or a CLOB

Parameters:

parameterIndex		index of the first parameter is 1, the second is 2, ...
reader		An object that contains the data to set the parameter value to.
length		the number of characters in the parameter data.

Exceptions:

SQLException		if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs; this method is called on a closed PreparedStatement or if the length specified is less than zero.
SQLFeatureNotSupportedException		if the JDBC driver does not support this method
