-----------------------------------
Summary: Auto wrapping with LIMIT query should not apply to
non-select queries
Key: DRILL-6960
URL: https://issues.apache.org/jira/browse/DRILL-6960
Project: Apache Drill
Issue Type: Bug
Components: Web Server
Affects Versions: 1.16.0
Reporter: Kunal Khatua
Assignee: Kunal Khatua
Fix For: 1.16.0
[~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.
