Api.JetIntersectIndexes method

Computes the intersection between multiple sets of index entries from different secondary indices over the same table. This operation is useful for finding the set of records in a table that match two or more criteria that can be expressed using index ranges. Also see IntersectIndexes(JET_SESID, []).

Parameters

• sesid
  Type: Microsoft.Isam.Esent.Interop.JET_SESID

  The session to use.

• ranges
  Type: []

  An the index ranges to intersect. The tableids in the ranges must have index ranges set on them. Use JetSetIndexRange(JET_SESID, JET_TABLEID, SetIndexRangeGrbit) to create an index range.

• numRanges
  Type: System.Int32

  The number of index ranges.

• recordlist
  Type: Microsoft.Isam.Esent.Interop.JET_RECORDLIST

  Returns information about the temporary table containing the intersection results.

• grbit
  Type: Microsoft.Isam.Esent.Interop.IntersectIndexesGrbit

  Intersection options.
