min

Returns the minimum value for the records within <expr>. NULL values are ignored unless all the records are NULL, in which case a NULL value is returned.

If <n> is specified, MIN returns the N minimum values from a column, which is the same results as the regular query FROM ... ORDER BY ... LIMIT n but as a variant list.

Syntax

min( <expr> )
min( <expr>, <n> )

Arguments

Required:

<expr>

A column name, which can be a qualified name (for example, database.schema.table.column_name).

<n> (named) (optional)

The number of minimum values to return.

Returns

• If <n> is not specified, MIN returns the same as the data type of the input values.
• If <n> is specified, MIN returns an ARRAY that contains all the <n> minimum values.

Examples

Get the minimum value:

VALUES (1), (1), (1), (4), (5), (6), (7), (8), (9), (10)
AGGREGATE min($0);

+---------+
| MIN($0) |
+---------+
| 1       |
+---------+

Get the minimum N value:

VALUES (1), (1), (1), (4), (5), (6), (7), (8), (9), (10)
AGGREGATE min($0, 5);

+-------------+
| MIN($0, 5)  |
+-------------+
| [1,1,1,4,5] |
+-------------+

Alternatively, use the named argument syntax:

VALUES (1), (1), (1), (4), (5), (6), (7), (8), (9), (10)
AGGREGATE min($0, n => 5);

+-----------------+
| MIN($0, n => 5) |
+-----------------+
| [1,1,1,4,5]     |
+-----------------+
