We've released a new 6-part video series covering every Rollup function in Tadabase, with simple examples showing how each one works in a Data Table.
The series covers everything from basic calculations to running totals, rankings, previous and next values, and more:
- Rollup Basics — Sum, Count, Average, Min, Max, Concatenate, and conditions
- Running Totals & Averages — Including restarting calculations for each group
- Rank, Row Number & Groups — Including how ties are handled
- Previous & Next Value — Compare each record to the one before or after it
- First, Last & Nth Value — Find values like a customer's first purchase or latest status
- Standard Deviation & Variance — See how these calculations work with visual examples
Each video is just 3–5 minutes and includes important rules and considerations, including how Order By affects your results and how ties are handled.
