I know that, but: what have you done to compare these random numbers with database?

So your question is not how to generate random number but it's how to compare random number with database. So all you have to do is assign that random number to a variable and connect to database and run a query to compare the two. Best is if you show us what have you done so far and where exactly are you stuck.

Can you explain a little bit more about your db table. Which field do you want to compare the random number with?

Two questions:
(1) are you trying to compare your generated value with all records in your table to, for example, try to select one record randomly?
Or,
(2) are you trying to check the values from the random function, itself?

If the first of these is similar to your needs, what SQL have you tried to use to check for this record?
