The first thing to check is whether blob and text can be distinguished from each other. I think they are advertised as blobs.
https://dev.mysql.com/doc/internals/en/com-query-response.html#column-type
If that's the case then using a DB.mapping could be an option.
Or, in order to use ResultSet#read(T) you a TextBlob type could be defined to add an overload that will handle that conversion and return String.
Or the String overload could handle reading from blobs.
In crystal, strings are utf-8 valid sequence only. For binary data a Slice need to be used.
