Either of the bookmarks can be a standard OLE DB-defined standard bookmark (DBBMK_FIRST, DBBMK_LAST, or DBBMK_INVALID). The value returned in pComparison indicates the relationship between the two bookmarks:

• DBCOMPARE_LT (cbBookmark1 is before cbBookmark2.)

• DBCOMPARE_EQ (cbBookmark1 is equal to cbBookmark2.)

• DBCOMPARE_GT (cbBookmark1 is after cbBookmark2.)

• DBCOMPARE_NE (The bookmarks are equal and not ordered.)

• DBCOMPARE_NOTCOMPARABLE (The bookmarks cannot be compared.)
