The result is returned as multiple record parcels (one per interval, including the master record) consisting of multiple fields whose values retain the underlying data type of the column on which statistics were collected. The summary set of information across all intervals is repeated for each interval. This information is reported by the following attributes:
- Date of statistics collection
- Time of statistics collection
- Number of rows on which statistics were collected for the specified column set
- Number of rows having at least one null in the specified column set
- Number of rows having all nulls in the specified column set
- Number of AMPs from which statistics were collected
- Overall average AMP rows per value
- Estimated cardinality of the table based on a single-AMP sample.
- Estimated cardinality of the table based on an all-AMP sample.
- Number of statistical intervals in the histogram
