Generates the count of non-null values for rows in each group that meet a specific condition. |
NOTE: When added to a transformation, 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. Transformations 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.
countaif(entries, entryValidation == 'Ok') |
Output: Returns the count of non-null values in the entries column when the entryValidation value is 'Ok'.
countaif(col_ref, test_expression) [group:group_col_ref] [limit:limit_count] |
