Daniel Barclay (Drill) commented on DRILL-2836:
-----------------------------------------------
We've recently added, as an internal (unsupported) diagnostic feature, a proxy
JDBC driver that traces calls made through it to another JDBC driver.
Using it should show the query that SquirreL is issuing and that is yielding
that no-such-column error (or show which call to a JDBC-API method is
internally yielding the query that yields that error).
To use the tracing proxy:
- reconfigure the JDBC client (e.g., Squirrel) to use a driver class of
{{org.apache.drill.jbdbc.proxy.TracingProxyDriver}},
- use a connection URL that consists of
"{{jdbc:proxy:org.apache.drill.jdbc.Driver:}}" prepended to the original URL
(e.g., "{{jdbc:drill:zk=local}}"),
- open a connection to that URL,
- use that connection (e.g., perform whatever steps let to the no-such-column
error), and
- look wherever stderr (the standard error output stream; Java's
{{System.err}}) is configured to be sent (e.g., your terminal, a SquirreL, log
file, etc.). (There should be lots of lines about JDBC method calls and
returns.)

> Project: Apache Drill
> Issue Type: Bug
> Components: Client - JDBC
> Affects Versions: 0.9.0
> Environment: Ubuntu 14.04 64 bits. Java "1.7.0_75". Latest SquirreL
> FX. Latest Netbeans
> Reporter: Mariano Ruiz
> Assignee: Daniel Barclay (Drill)
> Priority: Minor
> Fix For: 1.2.0

>
> I'm trying with latest build from Git repo, commit
> {{#be8d953935461ee6567b0c4d96c503e8b04469d2}}, I run a single node correctly
> with {{drillbit.sh}} and login with {{sqline}} through "Zookeeper" without
> problems.
> Also I developed a small Java main app and I was able to consume a MongoDB
> database with basics SQL queries without problem.
> But when I try to explore the databases from an advance SQL client like
> "SquirreL" (following the steps in the official
> [guide|https://cwiki.apache.org/confluence/display/DRILL/Using+JDBC+to+Access+Apache+Drill+from+SQuirreL]),
> or with the Netbeans Database Explorer, I cant connect with Apache Drill.
> In SQuirreL, I get this:
