If you want the query to return only the first 5 rows, you can use the LIMIT clause, which takes one parameter as the maximum number of rows to return. The following statement returns the first 5 rows from the fyi_links:

mysql> SELECT id, url, counts, tag FROM fyi_links 
   ORDER BY counts DESC LIMIT 5;
+-----+-------------------+--------+------+
| id  | url               | counts | tag  |
