One Row to Many

Each row is duplicated according to the number in the specified integer column. For example, you can use this node to create individual items in a shopping basket if you only have the number of items per basket, and then continue processing the duplicated rows.

Options

Prefix

The prefix for the new RowID. The new RowID is subsequently oldRowID + prefix + counter, where the counter is a number from 1 to the number of new rows.

Amounts

The integer column defining how many times the corresponding row is included in the output (e.g., the number of items in a shopping basket.) Rows with a value smaller than 1 are omitted.
