This whole process strikes me as very inefficient. There is no
mechanism to prevent your do-while loop from checking the same value
an infinite number of times (unless you log each random value and
check the next random value against the log AND the db).
I don't know what the purpose of the random value is in your app, but
I would suggest an entirely different approach. If you need random
values in the range of "min" through "max," you could generate a table
ahead of time consisting of the fields id and random_number, with max-
min+1 rows. (There are many random number generator sites available,
and you might be able to access one of their APIs as needed.)
It seems to me that it would be easier to generate these unique values
in some random order ahead of time, and then just associate the
random_numbers table with your current table through a 1-1
relationship. This process would make it easy to identify the next
random number to be assigned, and when the random numbers have been
exhausted.
Just a thought.
