>                 Key: DRILL-4436
>                 URL: https://issues.apache.org/jira/browse/DRILL-4436
>             Project: Apache Drill
>          Issue Type: Bug
>          Components: Storage - JDBC
>    Affects Versions: 1.5.0
>         Environment: Drill 1.5.0 with Zookeeper on CentOS 7.0 
>            Reporter: Vincent Uribe
>            Assignee: Serge Harnyk

> We have two tables in a MySQL database:
> CREATE TABLE `Gender` (
>   `genderId` bigint(20) NOT NULL AUTO_INCREMENT,
>   `label` varchar(15) NOT NULL,
>   PRIMARY KEY (`genderId`)
> ) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=latin1;
> CREATE TABLE `Civility` (
>   `civilityId` bigint(20) NOT NULL AUTO_INCREMENT,
>   `abbreviation` varchar(15) NOT NULL,
>   `label` varchar(60) DEFAULT NULL
>   PRIMARY KEY (`civilityId`)
> ) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=latin1;
> With a query on these two tables with Gender.label as 'gender' and Civility.label as
'civility', we obtain, depending of the query :
> * gender in civility
> * civility in the gender
> * NULL in the other column (gender or civility)
> if we drop the table Gender and recreate it with like this:
> CREATE TABLE `Gender` (
>   `genderId` bigint(20) NOT NULL AUTO_INCREMENT,
>   `label2` varchar(15) NOT NULL,
>   PRIMARY KEY (`genderId`)select * from Gender
> ) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=latin1;
> Everything is fine.
> I guess something is wrong with the metadata...
