Use the a_v4_extfn_orderby_list structure to describe the ORDER BY property of a table.
typedef struct a_v4_extfn_orderby_list { a_sql_uint32 number_of_elements; a_v4_extfn_order_el order_elements[1]; // there are number_of_elements entries } a_v4_extfn_orderby_list;
Data Member | Data Type | Description |

number_of_elements | a_sql_uint32 | The number of entries |
order_elements[1] | a_v4_extfn_order_el | The order of the elements |
There are number_of_elements entries, each with a flag indicating whether the element is ascending or descending, and a column index indicating the appropriate column in the associated table.
