I am working on a search
functionality.
I have created a search form in which user can search an Application based on Type
,ope
& Formate
.
I have used a subquery in my join query to get the desired result.
I have tested my query in MySQL Workbench
nad it's working fine.
But when I tried that same query in Codeigniter using query builder technique then I am facing a problem.
Here is the query which is worked fine in workbench:
SELECT (*)
FROM `App`
LEFT JOIN `App_type`
ON `App_type`.`app_id` = `App`.`id`
LEFT JOIN `App_formate`
ON `App_formate`.`app_id` = `App`.`id`
WHERE `App`.`id` IN(select app_id FROM App_type WHERE type_id in (3,2,6) group by app_id HAVING COUNT(*) = 3)
AND `App_formate`.`formate_id` IN('1', '3')
AND `jobs`.`ope_min` <= '3'
AND `jobs`.`ope_max` >= '3'
GROUP BY `jobs`.`id`;
This is the join query which I use:
$subquery = "select app_id FROM App_type WHERE type_id in ($selected_type) group by app_id HAVING COUNT(*) = $type_count";
$search_app_query = $this->db
->select('*')
->from('App')
->join('App_type', 'App_type.app_id = App.id', 'left outer')
->join('App_formate', 'App_formate.app_id = App.id', 'left outer')
->where_in('App.id',$subquery) //<-- Here is the problem
->where_in('App_formate.formate_id',$data['selected_formates'])
->where('App.ope_min <=',$data['ope_value'])
->where('App.ope_max >=',$data['ope_value'])
->group_by("App.id", "desc")
->get();
While I am debugging this problem it shows the
I have found the problem is in this part of the query:
"WHERE `App`.`id` IN('select app_id
FROM App_type
WHERE type_id in (3,2,6)
group by app_id HAVING COUNT(*) = 3')"
that single quote in this subquery is creating a problem.
What I have tried so far:
To remove this single quote I have tried
-
REPLACE($subquery, '''', '')
->where_in('App.id',trim($subquery,"'"))
-
$subquery_improved = substr($subquery, 1, -1);
But all this solution is not working. They are not removing the single quote.
Note: I am aware of $this->db->query()
but do not want to use that.
