In the range function, if step is a negative number, since the parameter is specified as usize, step=-1 is converted to 18446744073709551614, which leads to incorrect results. https://github.com/apache/arrow-datafusion/blob/9619f02db79c794212437415b1e6a53b44eef4c9/datafusion/physical-expr/src/array_expressions.rs#L749C50-L749C51 Therefore, we need to specially handle the case where step is a negative number.
run :
select range(1, 10, -2) result is [1]
select range(1, 10, -2)
[1]
As a comparison: duckdb {width=40px height=30px}
