> 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"
