MySQL Programming Question:

A LIKE condition is also called pattern patch. There are 3 main rules on using LIKE condition:

* '_' is used in the pattern to match any one character.
* '%' is used in the pattern to match any zero or more characters.
* ESCAPE clause is used to provide the escape character in the pattern.

The following tutorial exercise provides you some good pattern matching examples:

SELECT 'GlobalGuideLine.com' LIKE '%center%' FROM DUAL;
1

SELECT 'GlobalGuideLine.com' LIKE '%CENTER%' FROM DUAL;
1
-- Case insensitive by default

SELECT 'GlobalGuideLine.com' LIKE '%CENTER_com' FROM DUAL;
1
