-------------------------------------
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.
