Fetch rows

The program uses the FETCH statement to retrieve each row of output. This statement names a cursor and can also name the host variables that receive the data. The following example shows the completed code:
EXEC SQL DECLARE the_item CURSOR FOR
   SELECT order_num, item_num, stock_num
      INTO :o_num, :i_num, :s_num
      FROM items;
EXEC SQL OPEN the_item;
while(SQLCODE == 0)
{
   EXEC SQL FETCH the_item;
   if(SQLCODE == 0)
      printf("%d, %d, %d", o_num, i_num, s_num);
}
