  • Many databases have field names that are deliberately case insensitive. Depending on the database you're liable to get your field names back in either upper or lower case. Which one you get depends on the database you have.

    If you quote your field names then you will always get them back in the case you sent them as. This is much more convenient for an automated system.

    • You could also use NAME_lc and friends to specify whether names should be returned as lower or upper case.
      • And now the framework has to translate from the canonical case back to the original case that the programmer specified and is expecting. (Ruby is case sensitive, just like Perl is.)

        While there are other ways to work around it, the simplest way is just to quote the field name and watch problems disappear on you.
