Dataset Functions
Functions that return metadata and statistics about the current dataset, such as the dataset name, row count, file information, and auto-detected column mappings.
These functions describe the dataset itself rather than individual events, so ProcessMind resolves them while it evaluates the expression in the app, for example in the Expression Editor preview. They are not available in the dataset processing pipeline, which translates expressions into database queries: a calculated attribute or dataset filter that uses one of them fails to process.
lastDataUpdate
()Returns the timestamp of the most recent data upload or update.
| Returns | date |
| Examples | lastDataUpdate() → Timestamp of last update |
lastDateInData
()Returns the timestamp of the last event in the dataset.
| Returns | date |
| Examples | lastDateInData() → Timestamp of the last event in the data |
datasetName
()Returns the dataset's display name.
| Returns | string |
| Examples | datasetName() → Sales Orders |
datasetRows
()Returns the total number of rows, or events, in the dataset.
| Returns | number |
| Examples | datasetRows() → 15000 |
dataFreshnessDays
()Returns the number of days since the last data update.
| Returns | number |
| Examples | dataFreshnessDays() → 3 |
dataFileName
()Returns the original file name of the uploaded data.
| Returns | string |
