Hi,
I assume you are using this mysql package
http://code.dlang.org/packages/mysql-native.
(If not please check wheter the package you are using is vibe-d
compliant.)
The mysql package uses Variant from Phobos for storing values.
For your example, you could write
```res.writeBody(row[0].toString());```
Kind regards
Andre
