Accessors

OLE DB Programmer's Reference

Accessors used with IRowsetIndex::SetRange and IRowsetIndex::Seek for an integrated index follow the same restrictions as accessors used with these methods for a separate index:

  • For each key column bound in the accessor, all more-significant key columns must also be bound.
  • Key columns must be bound in order from most significant to least significant.
  • If the accessor binds any non-key columns, key columns must be bound first.

Accessors used with IRowsetIndex::SetRange and IRowsetIndex::Seek for an integrated index can also be used with other methods, such as IRowset::GetData, and vice versa.

Because the order of significance of columns can change for each index, it is usually necessary to define a different accessor to be used on SetRange or Seek calls for each index.
