[fw-general] Strange Problem with $select->where in Zend_Db_Table_Abstract::_fetch()

[Kjell Bublitz]

Hello, i am using 1.02.

Here is the method from a my User model:
  function exists($field, $value) {
    return $this->fetchAll(array($field => $value))->exists();
  }

This is what i set as $where (params for the above method):

  array(1) {
    ["user_name"] => string(7) "carzaib"
  }

In the class Zend_Db_Table_Abstract:

This is what actually goes to $select->where($key, $val);

  string(9) "user_name"
  string(7) "carzaib"

A snippet from the Abstract.php

  // $key is the condition with placeholder,
  // and $val is quoted into the condition
  $select->where($key, $val);

And here comes the final query:

SELECT `users`.`user_id`, `users`.`user_name`, `users`.`user_pass`, 
`users`.`user_mail`, `users`.`created_on` FROM `users` WHERE (user_name)

The where-clause is not complete.

What am i missing?
