Data metric functions

MIN (system data metric function)

Returns the minimum value for the specified column in a table.

The MIN system data metric function is optimized to calculate the minimum value for a single column and provides greater performance when compared to calling the MIN function.

This topic provides the syntax for calling the function directly. To learn how to associate the function with a table or view so it runs at regular intervals, see Associate a DMF to automate data quality checks.

Syntax

SNOWFLAKE.CORE.MIN(<query>)
Copy

Arguments

query

Specifies a SQL query that projects a single column.

Allowed data types

The column projected by the query must have one of the following data types:

  • FLOAT

  • NUMBER

Returns

The function returns either a NUMBER or FLOAT value.

Example

Measure the minimum value for the SALARY column in a table:

SELECT SNOWFLAKE.CORE.MIN(
  SELECT
    salary
  FROM hr.tables.empl_info
);
Copy
+------------------------------------------------------------+
| SNOWFLAKE.CORE.MIN(SELECT salary FROM hr.tables.empl_info) |
+------------------------------------------------------------+
| 60000                                                      |
