Mihai Budiu closed CALCITE-6868.
--------------------------------
Resolution: Invalid
It looks like this issue comes from our type system, which also specifies a
max_scale of 10.
Under these constraints, this is the correct solution.
I apologize for the noise produced.
> SqlTypeFactoryImpl.leastRestrictive produces incorrect results for DECIMAL
