C++
__property bool KeyExclusive = {read=GetKeyExclusive, write=SetKeyExclusive, nodefault};
Description
Controls the exclusion of the upper and lower boundaries of a range.
Use KeyExclusive to get or set the flag that controls whether a range should include or exclude the records that exactly match the starting and ending range values. By default, KeyExclusive is False, meaning that exact matching values are included.
To restrict a range to those records that are greater than the specified starting value and less than the specified ending value, set KeyExclusive to True. Setting KeyExclusive is possible only in dsSetKeyMode.
The property has meaning only for non-expressional indexes.
