SQL Server trigger - select random ID

Question

I am going to write a trigger which inserts a row into a table. The insert statement includes an ID column. I want my trigger to randomly choose one out of three IDs to insert, is it possible?

Answer 1

You can use the RAND function to generate a random number such that i <= x < j .

 FLOOR(i + RAND() * (j – i))

Here you can find the documentation on the RAND function.
