Considering the tree below, I have a question.
A
B c
D E F G
H I J K
So, I was wondering if there is any way to do a SELECT, where I bring all the IDS that are to the left of A. Because getting left the right side follows the same logic.
The program enrolls people. So person A put 'B' and 'C' in their network. B to the left C to the right. Then B put D and E, and there goes the tree. My question is, can I do a Select where I search all from the left side of A.
I thank you for your attention right away, Eric Augusto.
