/**
 * 在有些单据查询的时候，查询模板要查询的表不是固定的，是通过用户输入的条件动态决定的。
 * 这样的话就没有办法把查询模板跟某个元数据组件进行绑定，那么在平台生成sql的时候由于
 * 没有任何元数据信息，所有sql的from部分没有办法拼接，因为无法知道表之间的关联关系。
 * where部分的sql也只提供了单个条件的sql。这个类就是专门用来处理这种非元数据查询模板的
 * sql加工的

 * 使用这个工具的时候，在业务根据用户输入的信息明确要查那个实体时传入以下信息：
 * 
一个map：所有字段在查询模板中定义的fieldcode和该字段在所查实体中的元数据路径的一个映射，
 * 逻辑条件不需要映射，在后面拼sql的时候会检查，如果map中不存在该字段就把它当逻辑条件，
 * 拼sql的时候不会处理。因为非元数据查询模板大部分是在转单的时候使用的，在转单时这个map由查询模板的提供方构造。
 * 
待查主实体对应的vo class
 * 
查询方案Query Scheme
 * 

 * 加工sql的方式和元数据查询非常的相似：在拼固定条件的时候sql片段还是业务组自己来拼，
 * 但是业务组可能没有相关表的别名信息，提供{@link #getTableAliasOfFieldCode(String)}方法获取别名
 * 业务组的代码应该按照下面的方式写，和
 * {@link nc.vo.pubapp.query2.sql.process.QuerySchemeProcessor}的使用方式类似：
 * 

 * 
 * NonMetaQuerySchemeProcessor qrySchemeProcessor=new
 * NonMetaQuerySchemeProcessor(map,voclass,queryScheme);
 * String alias=qrySchemeProcessor.getTableAliasOfFieldCode
 * ("pu_order_b.pk_org");
