DBPROP_CANSCROLLBACKWARDS

Property group: Rowset

Property set: DBPROPSET_ROWSET

Column? N

Type: VT_BOOL

Typical R/W: R/W

Description: Scroll Backwards

Indicates whether the rowset can scroll backward.

Value Meaning
VARIANT_TRUE lRowsOffset in IRowset::GetNextRows or IRowsetLocate::GetRowsAt can be negative.
VARIANT_FALSE lRowsOffset must be non-negative.

If the rowset supports IRowsetLocate, the value of this property is VARIANT_TRUE because this method supports backward scrolling by definition.
