MySQL列中的随机数 [英] Random Number in MySQL column

问题描述

我正在尝试在我的数据库列之一中添加随机数，称为喜欢"，其中包含约5000行.目前，我已经尝试过像下面这样将随机数从10改为50.

I am trying to add random number in one of my database column called likes which have about 5000 row in it. currently I have tried like below to get random number from 10 to 50.

$randomnumberlike = (rand(10,50));

但这是在所有行中设置相同的数字...相反，我希望在行中设置不同的数字...任何人都可以建议我该怎么做?

but this is setting same number in all row...instead I want different number in row...anyone can please suggest how can I do it ?

谢谢

推荐答案

尝试:UPDATE Table SET fieldName = ((rand() * 1000) % 40) + 10;

由于在变量中对其进行预设时，所有内容都相同...

Because when you preset it in a variable, it'll be the same for all...
