1、權限問題
alter routine 編輯或刪除存儲過程
create routine 建立存儲過程
execute 創建存儲過程
2、存儲過程相關的一些命令
show procedure status\G 查看數據庫中有哪些存儲過程
show procedure status where db = 'db_name'\G 查看指定數據庫（db_name）中有哪些存儲過程
select name from mysql.proc where db = 'db_name'; 查看指定數據庫（db_name）中有哪些存儲過程
select routine_name from information_schema.routines where routine_schema = 'db_name'; 查看指定數據庫（db_name）中有哪些存儲過程
show create procedure dbname.sp_delete_bakhistory_new \G 查看存儲過程的詳細內容
3、MySQL 存儲過程刪除大表
delimiter //
CREATE PROCEDURE `sp_delete_bigtable_60`( )
BEGIN
declare v_id int;
declare stopflag int;
declare v_num int;
declare cursor_id cursor for select id from bigtable where gmt_created<now()-interval 60 day;
declare continue handler for not found set stopflag=1;
open cursor_id;
repeat
fetch cursor_id into v_id;
begin
delete from bigtable where id =v_id;
end;
set v_num=v_num+1;
if mod(v_num,100)=0 then
commit;
BEGIN
declare v_id int;
declare stopflag int;
declare v_num int;
declare cursor_id cursor for select id from bigtable where gmt_created<now()-interval 60 day;
declare continue handler for not found set stopflag=1;
open cursor_id;
repeat
fetch cursor_id into v_id;
begin
delete from bigtable where id =v_id;
end;
set v_num=v_num+1;
if mod(v_num,100)=0 then
commit;
end if;
until stopflag = 1
end repeat;
close cursor_id;
END;
until stopflag = 1
end repeat;
close cursor_id;
END;
//

需要注意的是DELIMITER //和DELIMITER ;兩句，DELIMITER是分割符的意思，因為MySQL默認以";"為分隔符，如果我們沒有聲明分割符，那么編譯器會把存儲過程當成SQL語句進行處理，則存儲過程的編譯過程會報錯，所以要事先用DELIMITER關鍵字申明當前段分隔符，這樣MySQL才會將";"當做存儲過程中的代碼，不會執行這些代碼，用完了之后要把分隔符還原。
如果是用MySQL的Administrator管理工具時，可以直接創建，不再需要聲明。
