             Summary: Infinite loop when retrieving decimal value with scale = -1
                 Key: DRILL-6713
                 URL: https://issues.apache.org/jira/browse/DRILL-6713
             Project: Apache Drill
          Issue Type: Bug
          Components: Client - C++
    Affects Versions: 1.14.0
            Reporter: Rob Wu


 

The server returns scale value of -1 for this query

select cast('999999999999999999' as decimal(18,0)) + cast('9999999999999999999999999999999999999' as decimal(38,0)) from (values(1))

 

The getValueAt() function did not take into account of the possibility of -1 scale and will go into infinite loop of appending 0 to the string buffer.

This can be reproduced query submitter.
