Subject [jira] [Created] (DRILL-3513) Convert and cast are too sensitive for empty values
Date Sat, 18 Jul 2015 14:36:04 GMT
Stefán Baxter created DRILL-3513:
------------------------------------

             Summary: Convert and cast are too sensitive for 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).
