CASE_FORMAT_VIOLATION_COUNT (system data metric function)¶

Returns the count of non-NULL column values that have inconsistent casing. A value is considered a violation if it is not entirely uppercase, not entirely lowercase, and not title-case. Use this function to validate casing conventions in codes, status fields, or identifiers.

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.CASE_FORMAT_VIOLATION_COUNT(<query>)

Arguments¶

query: Specifies a SQL query that projects a single column.

Allowed data types¶

The column projected by the query must have the VARCHAR data type.

Returns¶

The function returns a NUMBER value. NULL values are excluded from the count.

Example¶

Measure the number of values in the status column with inconsistent casing:

SELECT SNOWFLAKE.CORE.CASE_FORMAT_VIOLATION_COUNT(
  SELECT
    status
  FROM orders.tables.events
);
