RND将继续返回相同的随机数，直到更改种子为止.尝试在调用中使用GETDATE之类的函数来更改此种子.

RND will continue to return the same random number until the seed is changed. Try to use a function like GETDATE in your call to change this seed.

SELECT RAND( (DATEPART(mm, GETDATE()) * 100000 )<br />
           + (DATEPART(ss, GETDATE()) * 1000 )<br />
           + DATEPART(ms, GETDATE()) );

知道了！我用

Got it!! I use

unsigned char* query = "SELECT TOP 1 WordID FROM Word WHERE Level=''Easy'' ORDER BY Rnd(-10000000*TimeValue(Now())*[WordID]);";

很棒！！！
