Jialin Qiao created IOTDB-2203:
----------------------------------

             Summary: Support data query by Tags
                 Key: IOTDB-2203
                 URL: https://issues.apache.org/jira/browse/IOTDB-2203
             Project: Apache IoTDB
          Issue Type: New Feature
            Reporter: Jialin Qiao


Currently, we only support query timeseries schema by tags.  

Howerver, some users want to query data by tags, such as:  

select * from root.* where tag(Name1) =  a1 and tag(Name2) =  b1  

 

We need to design the SQL for tag query
