儲存過程在主從庫上的測試
儲存過程在主從庫上的測試：
結論：
從理論上來講，從庫可以不存在procedure, 主庫上執行的procedure，會在binlog中轉換為相應的sql語句，而不是呼叫procedure,
所以從庫上可以不存在這個procedure， 依然可以於主庫資料同步。
但是實際環境中，從庫上還是要有這個procedure的， 畢竟主庫down了之後，從轉為主的話，沒有相應的procedure，對於應用來說是錯誤 的。
--在主庫上
MariaDB [test]> create table test_pro(id int);
Query OK, 0 rows affected (0.09 sec)
MariaDB [test]> delimiter //
MariaDB [test]> create procedure insert_test_pro()
-> begin
-> declare i int;
-> set i=0;
-> while i<10 do
-> insert into test_pro values (i);
-> set i=i+1;
-> end while;
-> end;
-> //
delimiter ;
Query OK, 0 rows affected (0.33 sec)
MariaDB [test]> delimiter ;
MariaDB [test]> show master status;

-- 從庫上沒有建這個儲存過程：實際上從庫上是同步建了這個procedure的：

在從庫上檢視：
