Function PreparedImpl.queryRowTuple
Execute a prepared SQL SELECT command where you only want the first Row, and place result values into a set of D variables.
This method will throw if any column type is incompatible with the corresponding D variable.
Unlike the other query functions, queryRowTuple will throw
mysql if the result set is empty
(and thus the reference variables passed in cannot be filled).
If the SQL command does not produce a result set (such as INSERT/CREATE/etc),
then mysql will be thrown. Use
exec instead for such commands.
Prototype
void queryRowTuple(T...)(
ref T args
);

| args | A tuple of D variables to receive the results. |
