INVALID_LONGITUDE_PERCENT (system data metric function)¶

Returns the percentage of column values that are not a valid longitude: values outside the range -180 to 180. The percentage is computed over the total row count, including NULL values in the denominator.

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_PERCENT(<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 FLOAT value.

Usage notes¶

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

Example¶

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

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