我有一个无限循环的光标:
DECLARE
CURSOR cursor_ab IS
SELECT num_ab FROM abonne;
BEGIN
OPEN cursor_ab;
LOOP
FETCH cursor_ab INTO numeroAb;
dbms_output.put_line(numeroAb);
END LOOP;
CLOSE cursor_ab;
END;
/
你有什么想法吗?
感谢,
答案 0 :(得分:3)
你需要退出: 当cursor_ab%NOTFOUND;
时退出HTH
答案 1 :(得分:2)
正如已经指出的那样,当以这种方式编写循环时,您需要指定退出条件:
DECLARE
CURSOR cursor_ab IS
SELECT num_ab FROM abonne;
BEGIN
FOR numeroab IN cursor_ab LOOP
DBMS_OUTPUT.put_line (numeroab.num_ab);
END LOOP;
END;
/
但是,您可以通过让循环管理游标来完成PL / SQL中的相同操作:
Dim ctrl As Control
For Each ctrl In Me.Controls
If (ctrl.GetType() Is GetType(TextBox)) Then
If(ctrl.Name.StartsWith("textBoxArray") Then
'your code here
End If
End If
Next
