Rand() help needed

Posted on 16th Feb 2014 07:03 pm by admin

Hi all,

Can someone explain and give me a quick example of how I would go about this?

I have 100 values in a database with colum headings of t_val and t_name. If I wanted to update all 100 of these with a rand number how would I do this?

Would I do something like this?
Code: [Select]t_val1 = rand(1,10);

What I want to do is have different variances in the rand as well. So ten would be rand(1,10) and the next ten would be rand(5,20) for example?

Many Thanks
