类名称：QueryBuilder
方法名：prepare

QueryBuilder.prepare介绍

[英]Build and return a prepared query that can be used by Dao#query(PreparedQuery) or Dao#iterator(PreparedQuery) methods. If you change the where or make other calls you will need to re-call this method to re-prepare the statement for execution.
[中]构建并返回可由Dao#查询（PreparedQuery）或Dao#迭代器（PreparedQuery）方法使用的准备好的查询。如果更改where或进行其他调用，则需要重新调用此方法以重新准备要执行的语句。
