an_extfn_result_set_info structure

Facilitates the return of result sets to the calling SQL environment.

typedef struct an_extfn_result_set_info {
    a_sql_uint32                        number_of_columns;
    an_extfn_result_set_column_info     *column_infos;
    an_extfn_result_set_column_data     *column_data_values;
} an_extfn_result_set_info;

The following code fragment shows how to set the properties for objects of this type.

int columns = 2;
an_extfn_result_set_info    rs_info;

an_extfn_result_set_column_info *col_info =
    (an_extfn_result_set_column_info *)
    malloc( columns * sizeof(an_extfn_result_set_column_info) );

an_extfn_result_set_column_data *col_data =
    (an_extfn_result_set_column_data *)
    malloc( columns * sizeof(an_extfn_result_set_column_data) );

rs_info.number_of_columns   = columns;
rs_info.column_infos        = col_info;
rs_info.column_data_values  = col_data;
