title: How to make row bind with more than 2 tables using prosql in SAS
body: <p>I have multiple tables like <code>Table1</code> <code>Table2</code> <code>Table3</code>, <code>Table4</code>
  They have the same columns in the same order. I want to bind them vertically
  I have no idea of how to make it.
  I tried this code:</p>
  <pre><code>PROC SQL; 
  
      create table Table_final AS
  
      ( 
  
      select * from Table1 
  
      union all
  
      select * Table2 
      
      union all
  
      select * Table3 
    
      union all
  
      select * Table4 
  
      ); 
  
      QUIT;
  </code></pre>
  <p>But it doesn't work</p>
