--------------------------------------

             Summary: Datafusion queries involving a column name that begins with a number produces unexpected results
                 Key: ARROW-10329
                 URL: https://issues.apache.org/jira/browse/ARROW-10329
             Project: Apache Arrow
          Issue Type: Bug
          Components: Rust - DataFusion
            Reporter: Morgan Cassels


This bug can be worked around by wrapping column names in quotes.

Example:

{{let query = "SELECT 16_20mph, 21_25mph FROM foo;"}}

{{let logical_plan = ctx.create_logical_plan(query)?;}}

{{logical_plan.schema().fields() }}now has fields: {{_20mph, _25mph}}

The resulting table produced by this query looks like:
||{{_20mph}}||{{_25mph}}||
|16|21|
|16|21|

Every row is identical, where the column value is equal to the initial number that appears in the column name.
