One Row to Many

KNIME Data Generation version 4.2.0.v202002251753 by KNIME AG, Zurich, Switzerland

Each row is multiplied depending on the number in the integer column. (E.g. you can use this node to create the items in a shopping basket, if you only have the number of items per baskets and then continue with the multiplied rows.)


The integer column containing the number the given row should be printed. If the number is smaller than one, the row is not displayed afterwards. (E.g. the number of items in one shopping basket.)
The prefix for the new RowKey. The new RowKey is subsequently oldrowkey + prefix + counter, where the counter is a number from 1 to the number of new rows.
