title: Trouble creating view with concat(first_name, ' ', last_name)
body: <p>I have created the following SQL and I keep getting:
  ERROR 1583 (42000): Incorrect parameters in the call to native function 'CONCAT'. I am sure it is something simple but I have been staring at this so long I decided to ask you kind folks what I am doing wrong.</p>
  
  <pre><code>CREATE VIEW customer_info AS
    SELECT CONCAT(first_name, ‘ ‘, last_name) AS full_name,
      customer_id,
      street_address,
      city,
      state,
      zip,
      home_phone,
      mobile_phone,
      other_phone
  FROM customers;
  </code></pre>
