创建存储过程之前我们必须修改mysql语句默认结束符 ; 要不然我们无法创建成功
使用delimiter可以修改执行符号DELIMITER是分割符的意思，因为MySQL默认以";"为分隔符，如果我们没有声明分割符，那么编译器会把存储过程当成SQL语句进行处理，则存储过程的编译过程会报错，所以要事先用DELIMITER关键字声明当前段分隔符，这样MySQL才会将";"当做存储过程中的代码，不会执行这些代码，用完了之后要把分隔符还原。
修改操作
mysql> delimiter %;
创建
mysql> create procedure zrd ()
-> begin
-> select * from emp;
-> end%
Query OK, 0 rows affected (0.00 sec)
mysql> delimiter ;
调用
mysql> call zrd; +-------+------------+-----------+------+---------------------+---------+---------+--------+ | empmo | ename | job | mgr | hiredate | sal | comm | deptno | +-------+------------+-----------+------+---------------------+---------+---------+--------+ | 7369 | SMITH | CLERK | 7902 | 1980-12-17 00:00:00 | 800.00 | NULL | 20 | | 7499 | ALLEN | SALESMAN | 7698 | 1981-02-20 00:00:00 | 1600.00 | 300.00 | 30 | | 7521 | WARD | SALESMAN | 7698 | 1981-02-22 00:00:00 | 1250.00 | 500.00 | 30 | | 7566 | JONES | MANAGER | 7839 | 1981-04-02 00:00:00 | 2975.00 | NULL | 20 | | 7654 | MARTIN | SALESMAN | 7698 | 1981-09-28 00:00:00 | 1250.00 | 1400.00 | 30 | | 7698 | BLAKE | MANAGER | 7839 | 1981-05-01 00:00:00 | 2850.00 | NULL | 30 | | 7782 | CLARK | MANAGER | 7839 | 1981-06-09 00:00:00 | 2450.00 | NULL | 10 | | 7788 | SCOTT | ANALYST | 7566 | 1982-12-09 00:00:00 | 3000.00 | NULL | 20 | | 7839 | KING | PRESIDENT | NULL | 1981-11-17 00:00:00 | 5000.00 | NULL | 10 | | 7844 | TURNER | SALESMAN | 7698 | 1981-09-08 00:00:00 | 1500.00 | 0.00 | 30 | | 7876 | ADAMS | CLERK | 7788 | 1983-01-12 00:00:00 | 1100.00 | NULL | 20 | | 7900 | JAMES | CLERK | 7698 | 1981-12-03 00:00:00 | 950.00 | NULL | 30 | | 7902 | FORD | ANALYST | 7566 | 1981-12-03 00:00:00 | 3000.00 | NULL | 20 | | 7934 | MILLER | CLERK | 7782 | 1982-01-23 00:00:00 | 1300.00 | NULL | 10 | | 7777 | zhang | NULL | NULL | NULL | 2356.54 | 234.45 | NULL | +-------+------------+-----------+------+---------------------+---------+---------+--------+ 15 rows in set (0.00 sec) Query OK, 0 rows affected (0.00 sec)
