Class PreparedBatch

All Implemented Interfaces:
Closeable, AutoCloseable, Configurable<PreparedBatch>, ResultBearing

public class PreparedBatch extends SqlStatement<PreparedBatch> implements ResultBearing
Represents a prepared batch statement. Multiple bindings are added to the compiled statement and then executed in a single operation. This is, generally, a very efficient way to execute large numbers of the same statement where the statement only varies by the arguments bound to it. The statement starts with an empty binding. You bind a single batch of parameters with the usual SqlStatement binding methods, and then call add() to add the current binding as a batch and then clear it. An entire batch can be bound and added in one go with add(Map) or add(Object...).
