hoe n rijen te selecteren

MySQL/Postgres gebruiken:

  SELECT t.name,
         t.price,
         t.change
    FROM TABLE t
ORDER BY t.change DESC
   LIMIT 5

LIMIT clausule:

• MySQL-documentatie
• Postgres-documentatie

SQL Server gebruiken:

  SELECT TOP 5
         t.name,
         t.price,
         t.change
    FROM TABLE t
ORDER BY t.change DESC

TOP wordt minstens ondersteund op SQL Server 2000+

SELECT x.*
  FROM (SELECT t.name,
               t.price,
               t.change
          FROM TABLE t
      ORDER BY t.change DESC) x
 WHERE ROWNUM <= 5
