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 \'WithoutBook.com\' LIKE \'%center%\' FROM DUAL;
1
SELECT \'WithoutBook.com\' LIKE \'%CENTER%\' FROM DUAL;
1
-- Case insensitive by default
SELECT \'WithoutBook.com\' LIKE \'%CENTER_com\' FROM DUAL;
