ASF GitHub Bot commented on DRILL-3510:
---------------------------------------
Github user vdiravka commented on the issue:
https://github.com/apache/drill/pull/520
@laurentgo The branch is updated to master drill-1.11.0-SNAPSHOT.
Quoting_identifiers metadata is left without handling direct session
changes.
Also I found one issue, when tried to connect to drillbit by SQuirrel via
jdbc:
`java.lang.NoClassDefFoundError: javax/validation/constraints/NotNull
at
org.apache.drill.jdbc.impl.DrillMetaImpl.drillFieldMetaData(DrillMetaImpl.java:263)`.
This annotation was added in DRILL-5301.
I decided to add a new dependency for jdbc module in the context of this PR.

> Currently Drill's SQL parser uses backtick as identifier quotes, the same as
> what MySQL does. However, this is different from ANSI SQL specification,
> where double quote is used as identifier quotes.
> MySQL has an option "ANSI_QUOTES", which could be switched on/off by user.
> Drill should follow the same way, so that Drill users do not have to rewrite
> their existing queries, if their queries use double quotes.
> {code}
> SET sql_mode='ANSI_QUOTES';
> {code}
