Hi all,
Has anyone built any rules that compare data across two tables? How best did you accomplish this?
In a database, you would run two UNION queries (A-B and B-A) to find data that does not align across both tables.
To compare two systems, I built two Data Insight rules using the EXISTS syntax. This works really quickly, although to only compare current active records between two systems I will need to extend my initial design by building two custom DI views (one for each system with active records) to compare both ways. The rules are very simple but it does not look like the EXISTS can use any other parameters (eg status = 'Active') as part of the test (hence the DI views).
Any ideas on how a two-way comparison could be built in Data Insight?
regards
Adrian
