MySQL Programming Question:

There are a number of special characters that needs to be escaped (protected), if you want to include them in a character string. Here are some basic character escaping rules:

► The escape character () needs to be escaped as ().
► The single quote (') needs to be escaped as (') or ('') in single-quote quoted strings.
► The double quote (") needs to be escaped as (") or ("") in double-quote quoted strings.
► The wild card character for a single character (_) needs to be escaped as (_).
► The wild card character for multiple characters (%) needs to be escaped as (%).
► The tab character needs to be escaped as ( ).
► The new line character needs to be escaped as ( ).
► The carriage return character needs to be escaped as ( ).

Here are some examples of how to include special characters:

SELECT 'It''s Sunday!' FROM DUAL;
It's Sunday!

SELECT 'Allo, C'est moi.' FROM DUAL;
Allo, C'est moi.

SELECT 'Mon Tue Wed Thu Fri' FROM DUAL;
<pre> Mon Tue Wed Thu Fri</pre>
