Filtering changing examples
Hallo everybody
i got a data set with about 200000 rows und i want to use a specific filter.
Example:
Row1 Old Name1
Row2 New Name1
Row3 Old Name2
Row4 New Name2
Row5 Old Name1
Row6 New Name3
Row7 Old Name3
Row8 New Name3
A filter operator (or an other) shall filter by "Name1". If this Name changes (here: to "Name3" in Row6) the filter should filter by "Name3" and so on. Finally i wanna have all the rows (In this case: Row 1,2,5,6,7 and 8). In the end the whole data set should be grouped.
Anybody an idea? Thank you so much.
