--- title: Min/Max description: Compute the min/max value of a field canonical: https://docs.paradedb.com/documentation/aggregates/metrics/minmax --- `min` and `max` return the smallest and largest values of a column, respectively. ```sql Min SELECT pdb.agg('{"min": {"field": "rating"}}') FROM mock_items WHERE id @@@ pdb.all(); ``` ```sql Max SELECT pdb.agg('{"max": {"field": "rating"}}') FROM mock_items WHERE id @@@ pdb.all(); ``` ```ini Expected Response (Min) agg ---------------- {"value": 1.0} (1 row) ``` ```ini Expected Response (Max) agg ---------------- {"value": 5.0} (1 row) ``` See the [Tantivy documentation](https://docs.rs/tantivy/latest/tantivy/aggregation/metric/struct.MinAggregation.html) for all available options. ## SQL Min/Max Syntax SQL's `MIN`/`MAX` syntax is supported in beta. To enable it, first run ```sql SET paradedb.enable_aggregate_custom_scan TO on; ``` With this feature enabled, the following query is equivalent to the above and is executed in the same way. ```sql Min SELECT MIN(rating) FROM mock_items WHERE id @@@ pdb.all(); ``` ```sql Max SELECT MAX(rating) FROM mock_items WHERE id @@@ pdb.all(); ``` By default, `MIN`/`MAX` ignore null values. Use `COALESCE` to include them in the final sum: ```sql SELECT MIN(COALESCE(rating, 0)) FROM mock_items WHERE id @@@ pdb.all(); ```
