早上好!帮个忙吧!

Question

请帮帮我,写个例子说明daysbetween涵数的用法!

Answer 1

i:int;
Datetime1,Datetime2 :Datetime;
i := daysbetween(Datetime1,Datetime2);

Answer 2

between #2002-1-1# and  #2003-1-1#

Answer 3

好像写错了一个地方：
Datetime1,Datetime2 :Datetime;
改为
Datetime1,Datetime2 :TDatetime;
好像！

Answer 4

i:integer;
Datetime1,Datetime2 :TDatetime;
i := daysbetween(Datetime1,Datetime2);

Answer 5

呵呵 daysbetween函数返回的是两个日期之间的整数天数；譬如；
 函数daysbetween('2003-01-02 01:23:22','2003-01-03 01:23:20')的返回值就是0；
