Error running crypto functions on Dictionary arrays such as md5 #13444
Description
Describe the bug
A regression appears to have been introduced in
T
To Reproduce
This used to work in DataFusion 42.0.0 but doesn't in DataFusion 43.0.0:
DataFusion CLI v43.0.0
> create table t as values (arrow_cast('Foo', 'Dictionary(Int32, LargeUtf8)'));
0 row(s) fetched.
Elapsed 0.013 seconds.
> select md5(column1) from t;
Arrow error: Compute error: Internal Error: Cannot cast Utf8View to StringArray of expected type
Expected behavior
Query should complete
Additional context
I found this while writing tests in #13443 -- Feel free to take those tests to work on this issue
Those tests fail like this:
External error: query failed: DataFusion error: Arrow error: Invalid argument error: column types must match schema types, expected LargeUtf8 but found Utf8 at column index 0
[SQL] select md5(ascii_1) from test_basic_operator;
