> I am using MSSQL to fetch the records with max rows defined and distinct as true also for the select clause as following -
> Query q = new Query().from(table).selectDistinct().select(column).setMaxRows(20);
> So it is throwing Incorrect syntax near the keyword 'DISTINCT' error.
> I debugged the code and found that in SQLServerQueryRewriter.rewriteSelectClause(), we are appending TOP 20 after the select keyword so with distinct it becomes select TOP 20 DISTINCT <rest query> which is not correct.
> It should be select DISTINCT TOP 20 <rest query>.
