Output Table Schema
The table has a row for each source vertex. The reachable target vertices exclude the source vertex itself; that is, the function does not calculate the closeness and k-degree scores for loops.
Column | Data Type | Description |
---|---|---|
inv_sum_dist | DOUBLE PRECISION | Inverse of sum of shortest distances to all reachable target vertices. NULL if there are no reachable target vertices. |
inv_avg_dist | DOUBLE PRECISION | Inverse of average shortest distances to all reachable target vertices. NULL if there are no reachable target vertices. |
sum_inv_dist | DOUBLE PRECISION | Sum of inverse distances to all reachable target vertices. NULL if there are no reachable target vertices. |
kdegree | DOUBLE PRECISION | Total number of reachable target vertices. 0 if there are no reachable target vertices. |
accumulate_column | Same as in Vertices table | [Column appears once for each specified accumulate_column.] Column copied from Vertices table. These columns enable you to identify different closeness scores. |
