Use the % wildcard character to represent any string of zero or more characters. For example, to find all the phone numbers in the authors table that begin with the 415 area code:
select phone from authors where phone like "415%"
To find names that have the characters “en” in them (Bennet, Green, McBadden):
select au_lname from authors where au_lname like "%en%"
Trailing blanks following “%” in a like clause are truncated to a single trailing blank. For example, “%” followed by two spaces matches “X ”(one space); “X ” (two spaces); “X ” (three spaces), or any number of trailing spaces.
