CONTAINS_ SPACES_ COUNT (system data metric function)¶
Returns the count of non-NULL column values that contain at least one space, tab, or no-break space.
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¶
Arguments¶
querySpecifies 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 not counted.

- To count only values with leading or trailing whitespace, use UNTRIMMED_STRING_COUNT.
Example¶
