In addition to the methods described in the above table, a decomposable aggregate function contains these additional methods:
SqlmrErrorH (*getPartialRow)(
SqlmrTaskContextH taskContext,
void* customContext,
SqlmrRowViewH* output
) SQLMR_ERROR_RESULT;
SqlmrErrorH (*aggregatePartialRow)(
SqlmrTaskContextH taskContext,
void* customContext,
SqlmrRowViewH input
) SQLMR_ERROR_RESULT;
This table describes the member methods:
| Method | Description |
|---|---|
| getPartialRow | Gets the partial form of the aggregated value. |
| aggregatePartialRow | Aggregates a partial row computed by aggregateRow with in function instance. |
