public abstract void clearParameters () throws SQLException

Clears the current parameter values immediately.

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.

Exceptions:
SQLException    if a database access error occurs or this method is called on a closed PreparedStatement
