title: Sequelize - Join with multiple column
body: <p>I like to convert the following query into sequelize code</p>
  
  <pre><code>select * from table_a 
  inner join table_b 
  on table_a.column_1 = table_b.column_1
  and table_a.column_2 = table_b.column_2
  </code></pre>
  
  <p>I have tried many approaches and followed many provided solution but I am unable to achieve the desired query from sequelize code.</p>
  
  <p>The max I achieve is following :</p>
  
  <pre><code>select * from table_a 
  inner join table_b 
  on table_a.column_1 = table_b.column_1
  </code></pre>
  
  <p>I want the second condition also.</p>
  
  <pre><code>and table_a.column_2 = table_b.column_2
  </code></pre>
  
  <p>any proper way to achieve it?</p>
