Subject [jira] [Created] (DRILL-1134) CompilationException for 2 or more Filters on an array type
Date Fri, 11 Jul 2014 21:50:05 GMT
Aman Sinha created DRILL-1134:
---------------------------------

             Summary: CompilationException for 2 or more Filters on an array type 
                 Key: DRILL-1134
                 URL: https://issues.apache.org/jira/browse/DRILL-1134
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Codegen
            Reporter: Aman Sinha
            Assignee: Jinfeng Ni


The following query's generated code for the Filter consists of the doEval() block which has
redefinition of variable isNull which causes a compilation failure.  Note that isNull is not
even referenced in the generated code. 

SELECT columns[0] 
  FROM dfs.`/Users/asinha/data/regions.csv` 
WHERE cast(columns[0] as int) > 1 
  ANDcast(columns[1] as varchar(20))='ASIA';

}
 ] < CompileException:[ Line 82, Column 28: Redefinition of local variable "isNull"  ]"

I also get a Deadbuf access for this query, but that could be a separate issue.
