jdye64 opened a new issue, #5793:
URL: https://github.com/apache/arrow-datafusion/issues/5793
### Describe the bug
Invoking `OwnedTableReference::from("schema.1table")` produces an invalid
`TableReference` if the "table name" starts with a number. In this example the
result would be
```
Bare { table: "schema.1table" }
```
when in fact the correct result should be
```
Partial { schema: "schema", table: "1table" }
```
### To Reproduce
A simple test can be added to `datafusion/common/src/utils.rs` to reproduce
the bug.
```
#[test]
fn test_split_names() -> Result<()> {
let result = parse_identifiers_normalized("schema.1table");
assert_eq!(result.len(), 2);
Ok(())
}
```
### Expected behavior
Invoking `OwnedTableReference::from("schema.1table")` should produce the
result
```
Partial { schema: "schema", table: "1table" }
```
### Additional context
I have traced the issue to `sqlparser-rs` returning a `Token::Word` rather
than expected `Token::Period` at
https://github.com/apache/arrow-datafusion/blob/main/datafusion/common/src/utils.rs#L200
My main question is should be be handled in DataFusion or sqlparser-rs?
