title: How to insert Spaces in long Credit Card Number every X characters in T-SQL?
body: <p>I seem to have some kind of lapsus...</p>
  
  <p>How can I format a continuous credit card number to have blank space after every 4 digits in T-SQL?</p>
  
  <pre><code>TableName     | Cards                    |
  ColumnName    | CardNumber               |
  ExampleInput  | 80756201005803400471     | varchar(20)
  
  ExampleOutput | 8075 6201 0058 0340 0471 | varchar(25)
  </code></pre>
  
  <p>I whish to have <code>ExampleOutput</code> in a <code>SELECT</code> statement, performance is irrelevant.</p>
