我有两个测试查询
CREATE (a:TEST)
DELETE a
WITH a
WHERE a <> NULL
RETURN (a:TEST)
回传
Added 1 label, created 1 node, deleted 1 node, statement completed in 0 ms.
和
CREATE (a:TEST)
DELETE a
WITH a
WHERE a IS NOT NULL
RETURN (a:TEST)
回传
Node with id 1738 has been deleted in this transaction
根据,"<&g
procedure p(x : integer);
begin
a := 5;
x := x + 2;
end
在执行以下代码后,写下变量a的值:
a := 10;
p(a);
对于下列每个参数传递机制:
(i)按价值调用。a. 7,10
(ii)以提述方式提出要求。a. 12,12
(iii)按价值-结果调用。a. 7,7
下周有一次考试,我已经得到了模拟试卷的答案,但我很困惑X是如何分配给程序调用中的一个的。帮助是很棒的
谢谢
