Queries that uses different databases, uses different protocol versions

However, @code{FOUND ROWS()} will return the correct value,

Queries that don't use any tables are not cached.
Queries that don't use any tables or if the user has a column privilege for
any of the involved tables are not cached.
Before a query is fetched from the query cache, MySQL will check that
the user has SELECT privilege to all the involved databases and
tables. If this is not the case, the cached result will not be used.
