Loop End
Node at the end of a loop. It is used to mark the end of a workflow loop and collects the
intermediate results by row-wise concatenation of the incoming tables. The start of the loop is defined by the
loop start node, in which you can define how often the loop should be executed (either fixed or
derived from data, e.g. the "group loop start"). All nodes in between are executed that many times.
Dialog Options
- Add iteration column
- Allows you to add a column containing the iteration number to the output table.
- Uniquify row IDs
- If set, the iteration number is added to each row ID from the incoming table, thus making
the row IDs unique over all iterations. If unset, the incoming row keys are not altered. In this case you
have to make sure that there are not duplicate row IDs in different iterations. Otherwise an error occurs.
- Ignore empty input tables
-
If this option is checked empty input tables and there structure are ignored and will not cause the node to fail.
- Allow variable column types
-
If checked, the loop does not fail when the column types between different table iterations change.
