Advances a cursor to the next row of its result table and
    retrieves the values from that row. When used with a list
    cursor, the FETCH statement places the cursor on a specified
    position within a list and retrieves a portion of that list.
    When embedded in precompiled host language programs, the FETCH
    statement assigns the values from the row to host parameters. In
    interactive SQL, the FETCH statement displays the value of the
    row on the terminal screen.
