             Summary: Update to_number function to be consistent with CAST function
                 Key: DRILL-6817
                 URL: https://issues.apache.org/jira/browse/DRILL-6817
             Project: Apache Drill
          Issue Type: Improvement
            Reporter: Bohdan Kazydub
            Assignee: Bohdan Kazydub


{{In case when `drill.exec.functions.cast_empty_string_to_null` is enabled casting empty string ('') to numeric types will return NULL. If `to_number` is used to convert empty string to a number, UnsupportedOperationException will be thrown.}}

The aim is to make these functions (CASTs and `to_number`) work consistently as is done for date/time functions.
