title: Returning rows with same key when searching only one of them
body: <p>I have a query that is returning results:</p>
  
  <pre><code>DECLARE @VALUE_LIST varchar(1000) = 'B1'
  select * from mfr_attr 
  where attr_val like '%' + @VALUE_LIST + '%' and field_id = 90
  </code></pre>
  
  <p><a href="https://i.stack.imgur.com/McUkY.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/McUkY.png" alt="enter image description here"></a></p>
  
  <p>I want the 'like' statement to evaluate only on field_id = 90 but return all other rows too.</p>
  
  <p>Above I think what is wrong is that by using where  field_id = 90 it doesn't return the other field_id's but I need it the like statement to only evaluate against field_id = 90.</p>
