Kevin Liew created PHOENIX-3306:

             Summary: SQL_DATA_TYPE and SQL_DATETIME_SUB is always NULL
                 Key: PHOENIX-3306
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 4.7.0
         Environment: HDP 2.5
            Reporter: Kevin Liew
            Assignee: Kevin Liew

This column is the same as the DATA_TYPE column, except for interval and 
datetime data types.
For interval and datetime data types, the SQL_DATA_TYPE field in the result set 
will return SQL_INTERVAL or SQL_DATETIME, and the SQL_DATETIME_SUB field will 
return the subcode for the specific interval or datetime data type. (See 
Appendix D: Data Types.)

BI tools or SDKs may use this metadata field to do type conversion.
