SQL Injection: What is safe?

I'm writing a web application and ofcourse it has to be safe, so what is safe? Since SQL Injection is a upcoming trend I need make sure my app is 100% safe from SQL Injection attacks. I don't believe you can prevent a succesfull Injection by just escape your data with mysql_real_escape_string() (PHP). What is your advice?

mysql_real_escape_string() is supposed to do a pretty good job. If magic_quotes_gpc is enabled, first apply stripslashes() to the data. Using this function on data which has already been escaped will escape the data twice. Also note mysql_real_escape_string() does not escape % and _. These are wildcards in MySQL if combined with LIKE, GRANT, or REVOKE.

Also, ensure that all user input is limited to a set length. Choose the characters that are allowed for input and manually ensure, server side, that those are the only ones that are accepted.

I think that would cover it pretty well. Correct me if I'm wrong.
