Another question : Is there a way to do a request without using a variable to store the result ?
When I write
```val result = database.runQuery {
	QueryDsl.insert(Tables.user).single(User(username = request.username, password = request.password))
}```
If I remove the `val result =`  I get a `Type mismatch. Required: Query&lt;Unit&gt; Found: EntityInsertSingleQuery&lt;User&gt;` error, but I currently don't need to use the result

I use the db.runQuery(...) (not the lambda version), and I don't seem to have that problem?

Maybe you're using `fun someFunction() = db.runQuery { .. }` ? If so, try `fun someFunction() { db.runQuery { .. } }` ...

I assume that the code is probably being executed in a lambda function whose return value is Unit.
Try one of the following:
```database.runQuery { ... }.run {}```
or:
```database.runQuery { ... }.let {}```
or:
```database.runQuery { ... }
Unit```
