Hi, For the following implementations:
1) storing boolean strings in fields X and Y separately 2) storing the same info in a field XY as 3 enums: X, Y, B, N meaning only X is True, only Y is True, both are True or both are False Is there significant performance gain when we substitute "X:T OR Y:T" by "XY:B", while significant loss in "X:T" by "XY:X OR XY:B"? Or are they negligible? Thanks! Tea --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
