I did not know why this branch returns an empty String column.

Maybe we should cast the column into String column in previous.

// Null/Primitive array can cast into String column.
let column = columns[0].cast_with_type(DataType::String);
let column = column.string()?;

match column {
   Constant => {},
   Array(x) => {}
}

[sundy-li]

  if args[0].is_numeric() || args[0] == DataType::String || args[0] == DataType::Null {
            Ok(DataType::String)
        } else {
            Err(ErrorCode::IllegalDataType(format!(
                "Expected string/numeric, but got {}",
                args[0]
            )))
        }
