velvia opened a new pull request #8815:
URL: https://github.com/apache/arrow/pull/8815
Currently, DataFusion SQL statements that compare negative numbers result in
an exception, as negative numbers are incorrectly parsed. The error thrown is
`InternalError("SQL binary operator cannot be interpreted as a unary operator")`
This PR adds a quick fix in SQL planner.rs, to parse SQL of the form `
UnaryOp { op: Minus, expr: Value(Number("1")) } } ` etc from SQL such as `WHERE
col1 >= -1` to allow proper evaluation of the above SQL as a literal number.
