For positive test, enter a number above 09 above the "Result" column. It may not be exact science, but I believe its somewhere in the ballpark. A universally unique identifier (UUID) is a 128-bit label used for information in computer systems. To create a random decimal number between two values (range), you can use the following formula: SELECT RAND ()* (b-a)+a; Where a is the smallest number and b is the largest number that you want to generate a random number for. For example, suppose we want to generate a public-key cryptography system for a user with the initials "ABC". Random number generators can be hardware based. You could populate the table by looping through the number of integers you want to provide. We can easily convert this varbinary data to an integer based value.
