If you intend to include ‘s in your SQL, you need to escape it:

There are several ways to include
quote characters within a string:

• A “’” inside a string quoted with “’” may be written as “””.
• A “”” inside a string quoted with “”” may be written as “”””
• Precede the quote character by an escape character (“\”)
• A “’” inside a string quoted with “”” needs no special treatment and
  need not be doubled or escaped. In the
  same way, “”” inside a string quoted
  with “’” needs no special treatment.

Additionally, if you are constructing the SQL in a program, you should strongly consider escaping variables that go into SQL queries by using mysql_real_escape_string or its equivalent in your programming language. Failure to do so will make your application vulnerable to SQL injection attacks by whomever controls the data source for said variables (probably your users; keep in mind that “your users” can mean “the whole internet” depending on circumstances).

Edit: Quoted the dev.mysql.com instructions above.
