D toc
Excerpt

Generates the count of non-null values for rows in each group that meet a specific condition.

Info

NOTE: When added to a transform, this function is applied to the current sample. If you change your sample or run the job, the computed values for this function are updated. Transforms that change the number of rows in subsequent recipe steps do not affect the values computed for this step.

To perform a simple counting of non-nulls without conditionals, use the COUNTA function. See COUNTA Function.

snippetBasic

D code

pivot value: COUNTAIF(entries, entryValidation == 'Ok') group:City limit:1

Output: Generates a two-column table containing the unique values for City and the count of non-null values in the entries column for that City value when the entryValidation value is 'Ok'. The limit parameter defines the maximum number of output columns.
