title: Writing SQL where clause to exclude rows based on two conditions
body: <p>Hi there I have a database where I would like Select all rows, but excluding records where two conditions are both met. I can't work out how to write the where clause that does this.</p>
  
  <p>To give an example the table is:</p>
  
  <pre><code>Name | Date | Country
  </code></pre>
  
  <p>I want to select all rows except rows where the Name is Dave and the Date is > 20180101. So rows where the Name is Dave but the Date is &lt;= 20180201 should be included as should rows where the date is > 20180101 and the name is anything but Dave.</p>
