Difference between revisions of "Drop Duplicate Rows"

Revision as of 15:47, 22 June 2010

The Drop Duplicate Rows Node performs the equivalent to a "Select DISTINCT" operation on the current Data Table. Rows that are considered to be duplicates of other rows are removed. A duplicate row is one that contains identical values as another row.

Please see the example below, of a Data Table before and after executing a Drop Duplicate Rows Node (rows which will be deleted are marked with a red cross).
