NOT_WEEKDAY_COUNT (system data metric function)¶

Returns the count of non-NULL column values that fall on a Saturday or a Sunday.

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.

Syntax¶

SNOWFLAKE.CORE.NOT_WEEKDAY_COUNT(<query>)

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:

DATE
TIMESTAMP_LTZ
TIMESTAMP_TZ

Returns¶

The function returns a NUMBER value. NULL values are not counted.

Usage notes¶

The day of the week is determined with DAYOFWEEKISO, so the result does not depend on the WEEK_START session parameter.
For a TIMESTAMP_LTZ value, the day is determined in the session time zone. For a TIMESTAMP_TZ value, the day is determined from the value’s own time zone offset.

Example¶

Measure the number of weekend dates in the trade_date column:

SELECT SNOWFLAKE.CORE.NOT_WEEKDAY_COUNT(
  SELECT
    trade_date
  FROM finance.tables.trades
);
