R7.16 Schleifen in T-SQL verwenden
Aufgabe
Sollen Recordsets auf dem Server durchsucht/verarbeitet werden, bietet sich dafür eine Schleifenanweisung an.
Lösung
Verwenden Sie eine WHILE-Schleife, die solange ausgeführt wird, wie eine bestimmte Bedingung erfüllt ist.
Hinweis
In Verbindung mit WHILE werden in der Regel zwei weitere Anweisungen verwendet: BREAK und CONTINUE. Mit BREAK brechen Sie die Bearbeitung der Schleife ab, mit CONTINUE wird die Schleife neu gestartet.
Derartige Schleifen werden meist im Zusammenhang mit der zeilenweisen Bearbeitung von Datensätzen auf dem Server eingesetzt (Cursor-Programmierung).
