[jira] [Created] (IOTDB-2100) Change current result set format of disable align to four columns
Yuan Tian created IOTDB-2100:
--------------------------------
Summary: Change current result set format of disable align to four columns
Key: IOTDB-2100
URL: https://issues.apache.org/jira/browse/IOTDB-2100
Project: Apache IoTDB
Issue Type: New Feature
Components: Core/Query
Reporter: Yuan Tian
Currently, if we use disable align keyword, we will get a resultset with 2 * n columns(n is the number of the sensors), like:
Time, root.sg1.d1.s1, Time, root.sg1.d1.s2, Time, root.sg1.d1.s3
1 1 2 2.0 3 "3"
After some user survey, we decide to change the result format to fixed four columns, like:
Time, senser_id, value, data_type
1 root.sg1.d1.s1 1 INT32
2 root.sg1.d1.s2 2.0 FLOAT
3 root.sg1.d1.s3. "3" TEXT
