sql - Mysql - Multiple OR condition -

-

I am surprised that it is possible to transfer this code 

  SELECT foo from the bar WHERE Baz = 3 or falcon = 4 or falcon = 5

in something like this 

  Choose where foo where falcon = 3,4,5 Use the   
 
 
  IN  operator. 
 
  IN  operator allows you to specify more than one value in the  WHERE  section. 
 
 Query 
 
  Select the bar foo where to baz IN (3,4,5);
