Question

Hi I’m starting to query my database in codeigniter and everything is working fine on a basic select statement but after I added my sql functions everything turns down. Well basically I have a function to Propercase text in mysql which supposed to work like this:

SELECT proper(foo_bar) as foo from foo;

this one should return something like this:

|Foo    |
|Foo Bar|

Now applying the active records I expected it to be like this:

$this->db->select('proper(foo_bar)');
$query = $this->db->get('foo');

Well I still don’t know the part of aliasing but I need to solve this one for now but yes there is no return after this query. I think the CI read it as

Select 'proper(foo_bar)' from foo

which is obviously totally wrong.
And by the way, as much as possible I don’t want to manually key in my query like this:

 $query = $this->db->query("SELECT proper(foo_bar) as foo from foo");  

that would be impractical in my opinion. Any way to solve this? Thanks!

As stated by doc you should pass a second parameter to avoid field protection with backticks.

$this->db->select('proper(foo_bar) AS propfoo',FALSE);
