DB Active record bug in CI 1.7.x

[eluser]KeyStroke[/eluser]
Hi,

After upgrading the database files in CI to 1.7.x, I've noticed that, when using active records, and when I don't add spaces around the equal sign in the "where" clause like this:

Code:

$this->db->select('*')->from('user,city')->where('user.city_id=city.id')->get();

I get the following error:

A Database Error Occurred

Error Number: 1054

Unknown column ‘user.city_id=city.id’ in ‘where clause’

SELECT * FROM (`user`, `city`) WHERE `user`.`city_id=city`.`id`

A workaround has been posted within this thread:
