示例1: clearParameters

/**
 * In general, parameter values remain in force for repeated used 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 clearParameters
 * 
 * @exception SQLException
 *                if a database access error occurs
 */
