FROM behavior;

The output of the above code is as follows:

But my personal understanding is as follows:

Let's take the line dt = '20230214' and ORDER BY specifies that the value comparison field is score, that is, the current value is 4:

UNBOUNDED PRECEDING AND 1 PRECEDING indicates the range (-∞, 3] . The result of s1 should be [1, 2, 3] . But the result is [1,2] is not expected
3 PRECEDING AND 1 PRECEDING indicates the range is [1, 3] , s2 should be [1, 2, 3] ,
1 FOLLOWING AND 2 FOLLOWING indicates the range UNBOUNDED PRECEDING AND 1 PRECEDING 0, s3 should be UNBOUNDED PRECEDING AND 1 PRECEDING 1,
UNBOUNDED PRECEDING AND 1 PRECEDING 3 indicates the range UNBOUNDED PRECEDING AND 1 PRECEDING 4, s4 should be UNBOUNDED PRECEDING AND 1 PRECEDING 1, But the result is UNBOUNDED PRECEDING AND 1 PRECEDING 2 does not meet expectations
