1. What did you do?

use test;
drop table if exists t;
create table t(a int, b int);
insert into t values(1,2),(1,3),(2,3),(-1,1),(-1,-1);
prepare stmt from "select sum(b) over w, nth_value(b, ?) over w from t window w as (partition by a)";
set @a=1;
execute stmt using @a;

2. What did you expect to see?

mysql>  execute stmt using @a;
+---------------+------------------------+
| sum(b) over w | nth_value(b, ?) over w |
+---------------+------------------------+
|             0 |                      1 |
|             0 |                      1 |
|             5 |                      2 |
|             5 |                      2 |
|             3 |                      3 |
+---------------+------------------------+
5 rows in set (0.00 sec)

3. What did you see instead?

mysql>  execute stmt using @a;
ERROR 1210 (HY000): Incorrect arguments to nth_value
