Module mysql.commands
Use a DB via plain SQL statements.
Commands that are expected to return a result set - queries - have distinctive
methods that are enforced. That is it will be an error to call such a method
with an SQL command that does not produce a result set. So for commands like
SELECT, use the query functions. For other commands, like
INSERT/UPDATE/CREATE/etc, use exec.
