Great!

Last week I needed the same and had to use somethin like:

declare @a int
declare @b int

select @a = count(ID) from table_1
select @b = count(ID) from table_b

select @a, @b

This one is much better.

This is not correct, the new MySQL protocol (version 10) allows you to have multiple queries running concurrently over the same connection. Each is assigned a uniqe statement_id by the server.

This is described in the prepared statement API part of the “MySQL Internals” document.

(But okay, most of the MySQL drivers has per default disabled use of the prepared statement API. Apparently there are some unresolved bugs in the server when using it.)
