```shell
/*DML*/CREATE TABLE t41(v0 DOUBLE, v1 BOOLEAN, v2 STRING, v3 STRING);
/*DML*/INSERT INTO t41(v0, v2) VALUES ('NaN'::Double, 'd殪s7'), (0.4097890978398071, '顼)j');
> SELECT NTH_VALUE(tt0.v0, NULL) OVER (PARTITION BY tt0.v2 ORDER BY tt0.v0) FROM t41 AS tt0;
thread 'main' panicked at /Users/yongting/Desktop/code/my_datafusion/arrow-datafusion/datafusion/physical-expr/src/window/nth_value.rs:195:63:

D /*DML*/INSERT INTO t41(v0, v2) VALUES ('NaN'::Double, 'd殪s7'), (0.4097890978398071, '顼)j');
D SELECT NTH_VALUE(tt0.v0, NULL) OVER (PARTITION BY tt0.v2 ORDER BY tt0.v0) FROM t41 AS tt0;
┌────────────────────────────────────────────────────────────────────┐
│ nth_value(tt0.v0, NULL) OVER (PARTITION BY tt0.v2 ORDER BY tt0.v0) │
