三、测试

a) Mysql>select memc_servers_set(‘127.0.0.1 11211’);

b) Mysql>use test;

c) Mysql>create table t_1(id int ,name varchar(20));

d) Mysql>create trigger trigger_t_1add after insert on t_1 for each row set @tmp=memc_set(NEW.id,NEW.name);

e) Mysql>create trigger trigger_t_1update after update on t_1 for each row set @tmp=memc_set(NEW.id,NEW.name);

f) Mysql>Create trigger trigger_t_1del before delete on t_1 for each row set @tmp=memc_delete(OLD.id)

g) Mysql>Insert into t_1 values(7,’555555’),(3,’33333333’) ,(8,’ 888888888’) ,(9,’ 99999999999’);

h) Mysql>update t_1 set name=’update’ where id=1

i) Mysql>delete from t_1 where id=1;

j) Mysql>exit

k) telnet 127.0.0.1 1121

get 8
