Mit WHERE filtert man nach Zeilen aus einer Tabelle, die bestimmte Kriterien
erfüllen. Auf diese Weise kann man die Zeilen auf die Zeilen beschränken,
an der man interessiert ist. Auf diesen Klausel folgt eine Bedingung, die
entweder «true» oder «false» zurückgibt.
SELECT *
FROM customer
WHERE ID = 10;
