Rob Wu created DRILL-6713:
-----------------------------
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.
