title: Why is this error message for date in mysql arriving?
body: <p>I can't insert date here. My table was:</p>
  
  <pre><code>CREATE TABLE salary
  (
      emp_id int NOT NULL,
      basic int,
      net_salary double,
      salary_date date,
      FOREIGN KEY(emp_id) REFERENCES employee(emp_id)
  )
  </code></pre>
  
  <p>When I give:</p>
  
  <pre><code>INSERT INTO `salary`(`emp_id`, `basic`, `net_salary`, `salary_date`) 
  VALUES (121,5000,,20190-06-21)
  </code></pre>
  
  <p>it shows an error message:</p>
  
  <blockquote>
