I've been thinking about something more like this:

conn.exec("INSERT INTO table_name VALUES (", i, s, ")");

What I like about this, is that a real SQL insert can have lots of 
fields. Getting them all straight can be a pain in the ass, especially 
if you are inserting a couple somewhere.

But if the SQL library rearranges this for us, so we can put the data 
where it should be, it would be much nicer.

The one wrinkle that makes this difficult is strings that should be 
parameters. Are they parameters or SQL statement? I suppose you could 
wrap the statement strings into something, or the string values into 
something.

String interpolation would be really useful here. e.g.:
