>             Project: Apache Drill
>          Issue Type: Bug
>          Components: Web Server
>    Affects Versions: 1.16.0
>            Reporter: Kunal Khatua
>            Assignee: Kunal Khatua
>            Priority: Major
>              Labels: user-experience

>   Original Estimate: 168h
>  Remaining Estimate: 168h

> [~IhorHuzenko] pointed out that DRILL-6050 can cause submission of queries with incorrect syntax. 
> For example, when user enters {{SHOW DATABASES}}' and after limitation wrapping {{SELECT * FROM (SHOW DATABASES) LIMIT 10}} will be posted. 
> This results into parsing errors, like:
> {{Query Failed: An Error Occurred org.apache.drill.common.exceptions.UserRemoteException: PARSE ERROR: Encountered "( show" at line 2, column 15. Was expecting one of: <IDENTIFIER> ... }}.
> The fix should involve a javascript check for all non-select queries and not apply the LIMIT wrap for those queries.
