I analysis some errors and I think if we fix the way we parse sql, we can
find an optimal type for the literal easily
```
External error: statement failed: DataFusion error: Arrow error: Cast error:

External error: query failed: DataFusion error: Error during planning:
Internal error: Expect TypeSignatureClass::Native(LogicalType(Native(String),
String)) but received NativeType::Int64, DataType: Int64.
This was likely caused by a bug in DataFusion's code and we would welcome
that you file an bug report in our issue tracker No function matches the given
name and argument types 'ascii(Int64)'. You might need to add explicit type
casts.

String))))
