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. You can try them in the Expression Editor with a free trial.
