title: Query exceeded resource limits when merging data from two tables
body: <p>I have two tables t1 &amp; t2.  I want to take everything From t1, and only Hour column from t2. My query is as below:
  SELECT t1.*,t2.Hour FROM t1, t2</p>
  <p>It shows me the query exceeded resource limits. What is the best way to do this?
