[support] dbtng question

[a.sanchez75 at gmail.com]

Hello,

Sorry but I have a dummy question, is like a mistery for me. When I
run this sql query

$query = db_select('system', 'n');
$query->fields('n',array('type'))->condition('name', 'book');
$result =   $query->execute()->fetchAssoc();

I get results, but when I get (I replace 'contexthelp' string instead
of 'book' string)

$query = db_select('system', 'n');
$query->fields('n',array('type'))->condition('name', 'contexthelp');
$result =   $query->execute()->fetchAssoc();

I get empty results when I should get one row at least.
Just in case I have checked out the string contexthelp and is stored
in my system table.

Someone has any idea why I get this behavior?

Thanks in advance
