> You can try this: select (a + b) as c, count(*) from Table_A group by 1
```rust
#[test]
fn push_down_filter_groupby_expr_contains_alias() {
let sql = "SELECT (col_int32 + col_uint32) AS c, count(*) from test
group by 1";
let plan = test_sql(sql).unwrap();
let expected = "Projection: test.col_int32 + test.col_uint32 AS c,
COUNT(UInt8(1))\
\n Aggregate: groupBy=[[test.col_int32 + CAST(test.col_uint32 AS
Int32)]], aggr=[[COUNT(UInt8(1))]]\
\n TableScan: test projection=[col_int32, col_uint32]";
assert_eq!(expected, format!("{:?}", plan));
}
```
current implementation will put alias into projection expr
