<p>Stream insertion operator for String objects. </p>
<p>This doesn't have anything to do with the automatic quoting and escaping you get when using SQLTypeAdapter with Query. The need to use String with Query should be rare, since String generally comes in result sets; it should only go back out as queries when using result data in a new query. Since SQLTypeAdapter has a conversion ctor for String, this shouldn't be a problem. It's just trading simplicity for a tiny bit of inefficiency in a rare case. And since String and SQLTypeAdapter can share a buffer, it's not all that inefficient anyway. </p>
