> Convert and cast are too sensitive/strict when dealing with empty values
> ------------------------------------------------------------------------
>
> Key: DRILL-3513
> URL: https://issues.apache.org/jira/browse/DRILL-3513
> Project: Apache Drill
> Issue Type: Bug
> Components: Functions - Drill
> Affects Versions: 1.1.0
> Reporter: Stefán Baxter
> Assignee: Daniel Barclay (Drill)
>
> Working with slightly imperfect data is a hassle in drill unless one gives up
> and stores all data as strings.
> CONVERT_TO and CAST both throw exception if one is trying to convert empty
> string into numbers. These functions should return null value if the input is
> essentially a null value (or a pure string representation there off).
