Closeness Example: Weighted, Bounded Graph, MaxDistance=12 - Teradata Vantage

Input

Input tables are from AllPairsShortestPath Example: Unweighted, Unbounded Graph:

• Vertices: callers
• Edges: calls

SQL Call

SELECT * FROM Closeness (
  ON callers AS Vertices PARTITION BY callerid
  ON calls AS Edges PARTITION BY callerfrom
  USING
  TargetKey ('callerto')
  EdgeWeight ('calls')
  MaxDistance (12)
  Accumulate ('callerid', 'callername')
) AS dt ORDER BY callerid;

Output

 callerid callername inv_sum_dist        inv_avg_dist       sum_inv_dist        kdegree
