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.
