INVALID_LONGITUDE_COUNT (system data metric function)¶

Returns the count of column values that are not a valid longitude: values outside the range -180 to 180.

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.INVALID_LONGITUDE_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:

FLOAT
NUMBER

Returns¶

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

Usage notes¶

The range is inclusive, so -180 and 180 are valid.

Example¶

Measure the number of invalid longitude values in the longitude column:

SELECT SNOWFLAKE.CORE.INVALID_LONGITUDE_COUNT(
  SELECT
    longitude
  FROM geo.tables.locations
);
