Direct Query unnecessary CAST

Hi Anonymous ,
Sorry, I am not using DQ often, but I thought that Power BI only has type text type and if any text-like would automatically type-defined, it would be converted to this type.

Something like SELECT CAST(25.65 AS varchar). Did you try this?
Kind regards,
