Solr 数据导入处理程序中文档的静态字段 [英] Static field for document in Data Import Handlerfor Solr

问题描述

我通过以下方式从 db 中在 solr 中创建索引:

Im making an index in solr from db in the following way:

<document name="Index">  

<entity name="c" query="SELECT * FROM C">  

  <field column="Name" name="name"/>  

</entity>  

<entity name="p" query="SELECT * FROM P">  

  <field column="Name" name="name"/>  

</entity>  

</document>  

是否可以为每一行设置一个静态字段来表示返回给客户端的类型，以便可以根据来自 json 结果的信息调用正确的数据库表?

Is it possible to have a static field that is set for each row that signify what type is returned to client so that one can make a call to the right database table based on that information from the json result?

那个是表中没有列的字段

That is a field that has no column in the table

<field name="id" value="1"/> 

或者有其他方法可以解决这个问题吗?

Or is there another way to solve this?

推荐答案

<document name="Index">  
<entity name="c" transformer="TemplateTransformer" query="SELECT * FROM C">  
  <field column="Name" name="name"/>  
  <field column="id" template="1"/>  
</entity>  
<entity name="p" transformer="TemplateTransformer" query="SELECT * FROM P">  
  <field column="Name" name="name"/>  
  <field column="id" template="1"/>  
</entity>  
</document>
