Gary Gregory commented on CSV-168:
----------------------------------
I'm not sure about changing the behavior. What if you do want it escaped? I'm
not sure there is a case for that... What about adding a escapeNull boolean
setting?
> CsvFormat.nullString should not be escaped

> Key: CSV-168
> URL: https://issues.apache.org/jira/browse/CSV-168
> Project: Commons CSV
> Issue Type: Bug
> Components: Parser
> Affects Versions: 1.2
> Reporter: cornel creanga
> Priority: Minor
>
> Hello,
> Use case: I'm generating MySQL dump files (text format) - for more details
> check this - http://dev.mysql.com/doc/refman/5.7/en/select-into.html.
> Issue: The value null is represented as "\N". Also by default the escape char
> is '\N'. The CsvPrinter.printAndEscape method will convert this value into
> "\\N".
> I suggest to modify the CsvPrinter in order to not escape the nullString
> value - it should be written as it is. I can create a pull request if you
> want.
> I consider it a minor issue because it can be mitigated by making sure that
> the escape character is not a part of the nullString - however in my case it
> means that the LOAD commands should be modified accordingly.
