I am trying the return with a new column named count. Here is my query. $userid is the paramter to pass in
$select = $this->db->select()
->from('myfriend')
->where('fromid=?', $userid)
->join('user', 'user.userid = friends.toid')
->columns( new Zend_Db_Expr('Select count(*) where friends.toid = $userid as count'))
->order("id desc")
->limit(20);
I want to return a new column called count. where it will display number of rows where friends.toid = userid.
Seems to have some syntax error.
You must use double quotes, not single quotes, so php can eval $userid
, like "Select count(*) where friends.toid = $userid as count"
If you want to debug your query, you can always use:
echo $select->__toString()
