title: How can I design the query to properly select from the database
body: <p>The way I try to select:
  <code>SELECT * FROM products_translate WHERE (category IN(10)) AND .....</code></p>
  
  <p>The contents of the field in the database:
  category - 7, 10</p>
  
  <p>This structured query only shows products that are only categorized by category 10 but not those that contain another category. 
  For example 7, 10</p>
  
  <p>How can I properly structure the query?</p>
  
  <p>Database structure:</p>
  
  <pre><code>TABLE `products_translate` (
    `id` int(11) NOT NULL,
    `uniqueID` int(11) NOT NULL,
    `title` varchar(255) NOT NULL,
    `category` varchar(255) NOT NULL
  )
  </code></pre>
  
  <p>Accordingly, the category field may contain:
  <code>(1, 3, 7, 10)</code></p>
  
  <p>One of the records in the database
  <code>(109, 109, 'title', '7, 10')</code></p>
  
  <p>My purpose is to select 7, 10 database requests to output all the entries they contain in the category 7 or 10 field.</p>
