[jira] [Updated] (DRILL-1100) Returning NULL instead of
array-index-out-of-bound error in CSV files
[ https://issues.apache.org/jira/browse/DRILL-1100?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alexander Zarei updated DRILL-1100:
-----------------------------------
Summary: Returning NULL instead of array-index-out-of-bound error in CSV files (was: Returning NULL instead of array-index-out-of-bound error)
> Returning NULL instead of array-index-out-of-bound error in CSV files
> ---------------------------------------------------------------------
>
> Key: DRILL-1100
> URL: https://issues.apache.org/jira/browse/DRILL-1100
> Project: Apache Drill
> Issue Type: Bug
> Components: Client - JDBC, Client - ODBC
> Environment: SqlLine in Linux and C# in Windows
> Reporter: Alexander Zarei
> Priority: Minor
>
> When an out of bound column is queried, for example,
> SELECT columns[12] as column_12 FROM `dfs`.`root`.`./sneaky.csv`;
> the result is a column with all null values:
> +------------+
> | column_12 |
> +------------+
> | null |
> | null |
> | null |
> | null |
> | null |
> +------------+
> However, it makes more sense to return an error instead.
> The file content:
> someDirectoryFoo,true,false,false,100,root,root,"2013-10-11T14:31:58.000-0700","2013-10-11T14:31:58.000-0700","-rw-r--r--."
> someDirectoryBar,true,false,false,100,root,root,"2013-10-11T14:31:58.000-0700","2013-10-11T14:31:58.000-0700","-rw-r--r--."
> aFile,false,true,false,1234,root,root,"2013-10-11T14:31:58.000-0700","2013-10-11T14:31:58.000-0700","-rw-r--r--."
> anotherFile,false,true,false,2345,root,root,"2012-11-11T14:31:58.000-0700","2012-11-11T14:31:58.000-0700","-rw-r--r--."
