If you have a pattern that is too complex for LIKE to handle, you can use the regular expression pattern patch function: REGEXP_LIKE().
The following script provides you some good examples:
SELECT CASE WHEN REGEXP_LIKE ('FYICenter.com', '.*fyi.*',
'i') THEN 'TRUE' ELSE 'FALSE' END FROM DUAL;
TRUE
SELECT CASE WHEN REGEXP_LIKE ('FYICenter.com', '.*com$',
'i') THEN 'TRUE' ELSE 'FALSE' END FROM DUAL;
TRUE
SELECT CASE WHEN REGEXP_LIKE ('FYICenter.com', '^F.*','i')
THEN 'TRUE' ELSE 'FALSE' END FROM DUAL;
TRUE
