MCOL-5943: MCOL-4740 update rows counter for multi-table update (#3555)
* fix(plugin): MCOL-4740: This fixes update rows counter for multi-table update For UPDATEs involving a single table, the server call to handler::direct_update_rows() is used to correctly set the count for the number of updated rows in the UPDATE statement. However, for UPDATEs involving multi-tables, the server does not call handler::direct_update_rows(). This patch adds support to correctly report the number of updated rows to the client by setting multi_update::updated and multi_update::found in handler::rnd_end(). * fix(plugin): MCOL-4740: this is to addres the original patch QA found in the original patch --------- Co-authored-by: Roman Nozdrin <rnozdrin@mariadb.com> Co-authored-by: drrtuy <roman.nozdrin@mariadb.com>
