Are random number generators security holes?

If I retrieve a random number from a database (e.g. RAND() in SQL Server) or using a programming language and send this in some form back to a client machine, is there an economic chance I will be sending an indicator of what’s in my server’s memory that might form a security problem (like revealing my schema, etc)?

Generate unique integer from two integers with algorithm

I am currently trying to come up with an algoritm which would take at least two numbers
(say user IDs) and then come up with an unique number which is generated based on these two numbers. Each integer can be as big as an INT(11) in a Database (a number with 11 digits)
