--------------------------------------
Summary: Decimal type scale and precision are being flipped
sometime during a cast
Key: DRILL-1737
URL: https://issues.apache.org/jira/browse/DRILL-1737
Project: Apache Drill
Issue Type: Bug
Reporter: Jason Altekruse
Running this query I was trying to test the behavior of the test framework to
allow checking a baseline file, without providing type information for each
column in a csv. The idea is that the types that come out of the test query can
drive the interpretation of the baseline where strict type checking isn't
necessary. Unfortunately I ran into a bug when I was trying to make sure
decimal scale and precision could be retrieved from a result set with a decimal
column. It appears that the two values are being switched somewhere in the
process of running a cast. I plan on fixing this soon, but wanted to create a
JIRA to track the issue so I can post the patch for the test framework for
review.
To replicate:
select cast(dec_col as decimal(38,2)) dec_col from
cp.`testframework/decimal_test.json`
The file need only contain a single decimal in a field called dec_col in the
input file. I used a value of "3.7"
