title: compare two columns from two different tables in oracle sql for differences
body: <p>Hi first time posting for SQL,</p>
  
  <p>I need to compare two different columns from two different tables in SQL.</p>
  
  <p>For example there is two tables and each have one column in them and I need to compare them.</p>
  
  <p>Column1 is in table1 and column2 is in table2.</p>
  
  <p>I need to compare column1 and column2 for differences, I have looked online but was unable to find a query that would be able to help.</p>
  
  <p>Essentially I need to find the inconsistencies in the two columns from two different tables.</p>
