D toc

Excerpt

Generates the count of rows in each group that meet a specific condition. Generated value is of Integer type. 

Info

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 count of rows without conditionals, use the COUNT function. See COUNT Function.
