   > @cgivre, yes, it is a good idea. I've noticed that we have a lot of common 
test cases for different databases. It would be good to refactor those tests to 
avoid copying them.
   
   How did you have in mind?  When I wrote the JDBC reader, I added tests for 
Postgres and one other.  I duplicated all the writer tests for a bunch of 
databases.  Is there a more efficient way?

> In MS SQL Server, ORDER BY is mandatory for using OFFSET and FETCH clauses.  
> Drill (or Calcite) does not include an ORDER BY clause in the SQL it
