@alamb this is how we create expressions:
```rust
/// Parse a string predicate into an `Expr`
pub(crate) fn parse_predicate_expression(
schema: &DFSchema,
expr: impl AsRef<str>,
df_state: &SessionState,
) -> DeltaResult<Expr> {
let dialect = &GenericDialect {};
let mut tokenizer = Tokenizer::new(dialect, expr.as_ref());
let tokens = tokenizer
.tokenize()
.map_err(|err| DeltaTableError::GenericError {
source: Box::new(err),
})?;
let sql = Parser::new(dialect)
.with_tokens(tokens)
.parse_expr()
.map_err(|err| DeltaTableError::GenericError {
source: Box::new(err),
})?;
let context_provider = DeltaContextProvider { state: df_state };
let sql_to_rel =
SqlToRel::new_with_options(&context_provider,
DeltaParserOptions::default().into());
Ok(sql_to_rel.sql_to_expr(sql, schema, &mut Default::default())?)
}
```
