A table UDF or TPF can use row block structures to produce data.
The
a_v4_extfn_row_block row block has three fields:
- max_rows – How many table rows the row block can store in a piece of memory.
- num_rows – The number of rows actually produced or available for consumption. Cannot be larger than max_rows.
- row_data – The array of rows produced or available for consumption. Each row is an a_v4_extfn_row structure.
