IRowsetLocateImpl::Compare

Compares two bookmarks.

Syntax

  
      STDMETHOD ( Compare )(  
   HCHAPTER /* hReserved */,  
   DBBKMARK cbBookmark1,  
   const BYTE* pBookmark1,  
   DBBKMARK cbBookmark2,  
   const BYTE* pBookmark2,  
   DBCOMPARE* pComparison   
);

Parameters

See IRowsetLocate::Compare in the OLE DB Programmer's Reference.

Remarks

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.)
