Happy 2014 for everyone!
Here is my first problem of the year: I got a product table with "coded" hierarchy, like this:
| 1 | Level |
| 11 | Level |
| 111 | Level |
| 1111 | Level |
| 11111 | Product |
| 11112 | Product |
| 11113 | Product |
| 1112 | Level |
| 11121 | Product |
| 112 | Level |
| 1121 | Level |
| 11211 | Level |
| 112111 | Product |
| 112112 | Product |
| 112113 | Product |
How should I go about to create an hierarchy from this table? Keeping in mind that products could be in different levels.
Any ideas please?
Thanks very much!
