samuelcolvin opened a new issue, #10180: URL: https://github.com/apache/datafusion/issues/10180
### Describe the bug See https://github.com/datafusion-contrib/datafusion-functions-json/pull/3 I have a union defined by ```rs DataType::Union( UnionFields::new( vec![0, 1, 2, 3, 4, 5, 6], vec![ Field::new("null", DataType::Boolean, true), Field::new("bool", DataType::Boolean, false), Field::new("int", DataType::Int64, false), Field::new("float", DataType::Float64, false), Field::new("string", DataType::Utf8, false), Field::new("array", DataType::Utf8, false), Field::new("object", DataType::Utf8, false), ] ), UnionMode::Sparse, ) ``` When I try to compare it to an integer with `json_get(json_data, 'foo')=123`, I get the error: ``` called `Result::unwrap()` on an `Err` value: Plan("Cannot infer common argument type for comparison operation Union([(0, Field { name: \"null\", data_type: Boolean, nullable: true, dict_id: 0, dict_is_ordered: false, metadata: {} }), (1, Field { name: \"bool\", data_type: Boolean, nullable: false, dict_id: 0, dict_is_ordered: false, metadata: {} }), (2, Field { name: \"int\", data_type: Int64, nullable: false, dict_id: 0, dict_is_ordered: false, metadata: {} }), (3, Field { name: \"float\", data_type: Float64, nullable: false, dict_id: 0, dict_is_ordered: false, metadata: {} }), (4, Field { name: \"string\", data_type: Utf8, nullable: false, dict_id: 0, dict_is_ordered: false, metadata: {} }), (5, Field { name: \"array\", data_type: Utf8, nullable: false, dict_id: 0, dict_is_ordered: false, metadata: {} }), (6, Field { name: \"object\", data_type: Utf8, nullable: false, dict_id: 0, dict_is_ordered: false, metadata: {} })], Sparse) = Int64") ``` Is there any way to rewire the logic plan to tell datafusion how to implement these comparisons? If not, I might have to abandon the `json_get` method, and instead implemtn `json_get_str`, `json_get_int` etc., which would be unfortunate. ### To Reproduce see tests in https://github.com/datafusion-contrib/datafusion-functions-json/pull/3 ### Expected behavior _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
