title: Better way SQL insert query
body: <p>Actually, I don't know what is different the following query?</p>
  
  <p>Which one is better(performance, etc...)? Btw, I use SQL Server.</p>
  
  <p>Query 1 : </p>
  
  <pre><code>INSERT INTO PERSON (ID, NAME, ADDRESS) VALUES('001', 'Smit', 'London');
  INSERT INTO PERSON (ID, NAME, ADDRESS) VALUES('002', 'Jhon', 'London');
  </code></pre>
  
  <p>Query 2 : I never saw before</p>
  
  <pre><code>INSERT INTO PERSON (ID, NAME, ADDRESS)
  SELECT '001', 'Smit', 'London' UNION ALL
  SELECT '002', 'Jhon', 'London'
  </code></pre>
