Hal's Occasional Newsletter of July 2000 covered the BitAnd function nicely.
But I need something that has more than 1, 2, 4, 8, 16 as options, and is
extensible.
About the only solution I've come up with is a list, where possible list
members (attributes) are: 0,1,2...9,A,B,...,Z,AA,BB,......., etc.
Then Record 23 could have a list of attributes like 1,A,Z,9,R that is
stored in one column (VARCHAR).
For various reasons I don't want to use a small table to list the
attributes for a given record, such as for Record 23:
ID Attribute
23 1
23 A
23 Z
23 9
23 R
Do you have a better solution than a list?
best, paul
