Indexing abstract values - Take the CHALLENGE !
Posted by: james brooks

im trying to make sort of an unusual logic for my table X

the values i write to the corresponding field in table X are masked, those of you who know subnetting will probably understand this easier:

ID - Value
1 - A
2 - B
4 - C
8 - D
16 - E
32 - F
64 - G

These are some values that can be stored in the field, yet they are not stored as shown above, all the ID get added together building 1 number.

What i want to acomplish is, that it should be possible indexing the table sothat i can look for - lets say - value B or value C and D etc without having to loop through the whole table..

one idea i had was forming additional groups A (val A-C), B (val D-F) etc - as for egsample B would have to be in group A, and C & E would be in groups A and B etc so in the end the groups could be indexed.. but there shud b a better way =/

any ideas?

thank you!
