Select … where … OR

Question

Is there a way to select data where any one of multiple conditions occur on the same field?

Example: I would typically write a statement such as:

select          


        

Answer 1

while in is a shortcut for or and I wasn't sure how I could combine in with and, I did it this way

 SELECT * FROM table
 WHERE column1='x' AND (column2='y' OR column2='z');
