cetra3 opened a new issue, #22053: URL: https://github.com/apache/datafusion/issues/22053
### Describe the bug The Unparser doesn't support `IS DISTINCT FROM` in statements. This break things, especially with the new `array_has` null semantics (https://github.com/apache/datafusion/pull/21743) and optimizer passes. I.e, the following fails outright in the unparser: ```sql SELECT value IS DISTINCT FROM 1 FROM t ``` The following fails after an optimization pass: ```sql SELECT CASE WHEN value > 0 THEN true ELSE false END FROM t ``` ### To Reproduce Simple to fail: ```rust #[tokio::test] async fn unparse_is_distinct_from() -> Result<()> { let ctx = SessionContext::new(); let schema = Arc::new(Schema::new(vec![Field::new( "value", DataType::Int32, true, )])); ctx.register_table("t", Arc::new(MemTable::try_new(schema, vec![vec![]])?))?; let df = ctx .sql("SELECT value IS DISTINCT FROM 1 FROM t") .await?; let sql = plan_to_sql(df.logical_plan())?; Ok(()) } ``` ### Expected behavior _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
