I had the following idea: Allow any SQL statement. If the statement
starts off

SELECT xxx ....

then examine "xxx". If it contains only letters, digits and underscores,
then assume that a single data value is going to be returned and just
pass back that value. Otherwise, assume multiple values and return them
in the key=value format, searching for multiple rows as well.

Does this seem plausible?
