> [C++] CSV empty quoted string is treated as NULL
> ------------------------------------------------
>
> Key: ARROW-10115
> URL: https://issues.apache.org/jira/browse/ARROW-10115
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Affects Versions: 1.0.1
> Reporter: Maciej
> Assignee: Antoine Pitrou
> Priority: Major
> Labels: pull-request-available

> When parsing my CSV I have set
> {color:#267f99}ConvertOptions{color}::s{color:#001080}trings_can_be_null{color}
> to true.
> Now as I have values:
> {code:java}
> 1234,"",345
> {code}
> the string value which is an empty string is treated as NULL.
> I've checked default valeus of
> {color:#267f99}ConvertOptions{color}::{color:#001080}null_values{color} and
> there is empty string considered null, but here we have empty quoted string
> which shouldn't be treated as NULL in my opinion. Similar behavior we have in
> Postgresql, empty quoted string is not treated as a NULL:
> https://www.postgresql.org/docs/12/sql-copy.html
