I spent some time on tracing code but found unable to fix it.
Maybe we need to change some code in `sqlparser`, correct me if I am wrong.
<details open>
<summary>Detail</summary>
To be specific, I run following with debugger attached
<pre>
let df = ctx.sql("SELECT 1 as col0").await?;
let expr = df.parse_sql_expr("1 + 3 * col0 as new_col0")?;
</pre>
And found [this
line](https://github.com/apache/datafusion/blob/1e31093fc96d70f27d79935f616af31f1994b2e1/datafusion/sql/src/parser.rs#L388),
whose value return from `sqlparser` to be following.
> It doesn't contain `new_col0`.
<pre>
BinaryOp { left: Value(Number("1", false)), op: Plus, right: BinaryOp {
left: Value(Number("3", false)), op: Multiply, right: Identifier(Ident { value:
"col0", quote_style: None }) } }
</pre>
