| Hi all, I need some help designing a SQL statement. I am building a customer segmentation module where I can take a group of customers and split them n-ways by percentage. For example, my count comes back with 2500 and I would like to split that 3 ways (25%, 35% and 40%). I also must make sure that this is done dynamically (no temp tables)and I do not replicate customers across the 3 split groups. The results are populated onto the screen,one split group at time. I am having problems with the SQL/algorithm to make sure that all 3 splits always add up to the number above - 2500 in this case. Any ideas?Thanks.Alex. |
