Codeigniter Mysql column with comma seperated values

Question

I wnat to test a field with multiple values against single value, my SQL is like .

 WHERE id (1); 

Database values are like

 id --- 1,2 2,3 1,3,4 

codeigniter

 $this->db->select('*'); $this->db->from('content'); $this->db->where('name', $name); $this->db->where('id', $id); 

I tried

 $this->db->where_in('id', explode(',', $id)); 

but its not working.Please help me to solve this.

Answer 1

To find the values from a given set you can use FIND_IN_SET

$this->db->where("FIND_IN_SET(".$id.",id) >", 0);

Note: This type of design is considered as a bad design and you should normalize your structure, I suggest you to have a look at Database Normalization

Answer 2

What if you use like() instead of where()

$this->db->like('id', $id);
// Produces: WHERE `id` LIKE '%2%' ESCAPE '!'

Note: If 2 is the value 2 , 22 , 222 will pass through this

Answer 3

Please try this one:

$this->db->select('*')->from('table_name')
       ->where("column_name LIKE '%$key_values%'")->get();
