# MIN OVER

Returns the minimum value within the requested window.

For more information on usage, please refer to [Window Functions](/reference-sql/functions-reference/window).

## Syntax

```sql theme={"theme":{"light":"css-variables","dark":"css-variables"}}
MIN( <expression> ) OVER ( [ PARTITION BY <partition_by> ] )
```

## Parameters

| Parameter        | Description                                       | Supported input types |
| :--------------- | :------------------------------------------------ | :-------------------- |
| `<expression>`   | A value used for the `MIN` function               | Any                   |
| `<partition_by>` | An expression used for the `PARTITION BY` clause. | Any                   |

## Example

The example below shows each player's score alongside the lowest score in their level. Unlike a regular `MIN()` aggregation, the window function keeps one row per player while also showing the partition minimum.

<div className="query-window">
  ```
  SELECT
      nickname,
      level,
      current_score,
      MIN(current_score) OVER (PARTITION BY level) AS lowest_score
  FROM
      (VALUES
          ('kennethpark', 9, 76),
          ('sabrina21', 9, 90),
          ('burchdenise', 10, 79),
          ('ymatthews', 10, 85),
          ('rileyjon', 10, 80)
      ) AS t(nickname, level, current_score)
  ORDER BY level, nickname;
  ```
