Remove rows from the top dataset with key values that are present in the lower dataset.



Subtract from the top dataset all the records with ids in the bottom dataset:


how to subtract rows from a dataset with ids in another dataset example






The output depends on the vertical (Y-axis) position of the inputs.

Select Top key column for the column you want to match in the top input dataset.

Select Bottom key column for the column you want to match in the bottom input dataset.

Check case sensitive to use case sensitive matching for keys.



If there are 10k rows or less in both datasets, Easy Data Transform will try to guess sensible default values for Top key column and Bottom key column based on column header names and contents.

If the first input has a header, this will be used for the output.

All values are treated as text and comparisons are whitespace sensitive. You can use Whitespace to remove whitespace before the subtract.

All rows in the top dataset with a given key value are removed if that key value occurs 1 or more times in the bottom dataset.

You can use Concat Cols to join several columns together (e.g. 'first name' and 'last name' columns) to form a key column.

You can use Row Num to create a unique key column.
