Active Records and comma char

[eluser]WanWizard[/eluser]
No, the manual states:

If you set it to FALSE, CodeIgniter will not try to protect your field or table names with backticks. This is useful if you need a compound select statement.

This works, and is not the problem. The bug is that the code interprets the comma as a field separator. It splits the string to check for table names so it can add a table prefix. This breaks the CONCAT.
