wangxiaoying opened a new issue, #2225:
URL: https://github.com/apache/arrow-datafusion/issues/2225
**Describe the bug**
The `sql` function will throw an error: ` Plan("'LargeUtf8 = Utf8' can't be
evaluated because there isn't a common type to coerce the types to")` when
filtering on a `LargeUtf8` column.
**To Reproduce**
```Rust
fn main() {
let id_array = Int32Array::from(vec![1, 2, 3, 4, 5]);
let lrgstr_array = LargeStringArray::from(vec!["1", "2", "3", "4", "5"]);
let schema = Schema::new(vec![
Field::new("id", DataType::Int32, false),
Field::new("lrgstr", DataType::LargeUtf8, false),
]);
let batch = RecordBatch::try_new(
Arc::new(schema),
vec![
Arc::new(id_array),
Arc::new(lrgstr_array),
],
)
.unwrap();
let mut ctx = ExecutionContext::new();
let db1 = MemTable::try_new(batch.schema(), vec![vec![batch]]).unwrap();
let sql = "select * from t1 where lrgstr = '1'";
ctx.register_table("t1", Arc::new(db1)).unwrap();
let rt = Arc::new(tokio::runtime::Runtime::new().expect("Failed to
create runtime"));
let df = rt.block_on(ctx.sql(sql)).unwrap();
}
```
**Expected behavior**
No error.
