How to count number of deleted rows from one table in delete + join structure?
I use the following query, to delete the rows from two tables
delete
itc, ic
from
incoming_tours ic
join
incoming_tours_cities itc on itc.id_parrent = ic.id
where
ic.sale = '5'
How can i get the number of affected rows from ic table? (mysql_affected_rows returns t开发者_如何学运维he total count, i need only from one table). (I use MyISAM engines in my tables, that is why i don't use foreign keys here)
Thanks much
Count the rows beforehand.
select count(*) as sale_rows from ic where ic.sale = '5'
Do it in a transaction to make sure the table does not change between the SELECT and DELETE commands.
You can't use affected_rows for this. I think you can use a session variable in an after delete trigger on ic to count deleted rows.
