Which RDBMS are you using?

mySQL knows LIMIT

SELECT clicks FROM clicktable ORDER BY clicks DESC LIMIT 1,3


SQLServer for example has the TOP keyword

SELECT TOP 3 clicks FROM clicktable ORDER BY clicks DESC

Do you want a SQL solution or a PHP one?

SQL: have a look at aggregat functions for Strings like SUBSTRING
$text100=PHP substr($text,0,100);
