Tried my best to find a title, but not sure how to post it exactly... So...
I have a table 1
| Name | ID |
| John | 1 |
| George | 2 |
| Jim | 3 |
| Bill | 4 |
and I have another table 2
| Name | ID |
| Chris | 1 |
| Patric | 2 |
| Francois | 3 |
I want to always keep the second table, and put on the beginning of the second table the first one and adjust the ID accordingly.
Preferably I would like to do that with collections..
The result I want is :
| John | 1 |
| George | 2 |
| Jim | 3 |
| Bill | 4 |
| Chris | 5 |
| Patric | 6 |
| Francois | 7 |
Hope you understood the needed result!
Thank you in advance 🙂
