> The error appears to be specific to an expression involving a decimal type within a case
expression. If the math expressions are projected on their own the error is not thrown.
> Assignment conversion not possible from type "org.apache.drill.exec.expr.holders.NullableDecimal28SparseHolder"
to type "org.apache.drill.exec.expr.holders.NullableDecimal38SparseHolder"
> select                      
> CASE when 'A' = 'A' THEN FIN_FINANCE_FACT.AMOUNT_MONTH * - 1 ELSE FIN_FINANCE_FACT.AMOUNT_MONTH
 * 1 END  AS STMT_MONTH, 
> CASE WHEN 'A' = 'A'  THEN FIN_FINANCE_FACT.AMOUNT_YEAR_TO_DATE * - 1 ELSE FIN_FINANCE_FACT.AMOUNT_YEAR_TO_DATE
 * 1 END AS STMT_YEAR
> FROM         dfs.gosalesdw1021p.FIN_FINANCE_FACT
