Get the number of affected rows in a MySQL update statement?

Question

I have stored procedure in MySQL, something like the below:

create procedure SP_Test (input1 varchar(20))
begin
update Table1 set Val1=\'Val\' where country=         


        

Answer 1

Use ROW_COUNT():

SELECT ROW_COUNT();

Answer 2

Try the following code:

int mysql_affected_rows ([ resource $link_identifier = NULL ] )

Answer 3

one way, not very optimal is to simply do a select before you do the update.

select count(*) from table1 where country = 'country1'
