【MySQL】调用储存过程显示 ERROR 1305 (42000): PROCEDURE test.sp1 does not exist

问题描述：

        1.在MySQL中创建了一个简单的查询存储过程：

mysql> CREATE PROCEDURE spl() SELECT VERSION();
Query OK, 0 rows affected (0.01 sec)

         2.然后用CALL调用此存储过程，报错 ERROR 1305 (42000): PROCEDURE test.sp1 does not exist：

mysql> CALL sp1;
ERROR 1305 (42000): PROCEDURE test.sp1 does not exist

 问题排查：

         1.首先考虑是否是此储存过程当真不在，查看当前存储过程，发现存储过程存在：

mysql> SHOW PROCEDURE STATUS;
+------+------+-----------+----------------+---------------------+---------------------+---------------+---------+----------------------+----------------------+--------------------+
| Db   | Name | Type      | Definer        | Modified            | Created             | Security_type | Comment | character_set_client | collation_connection | Database Collation |
+------+------+-----------+----------------+---------------------+---------------------+---------------+---------+----------------------+----------------------+--------------------+
| test | spl  | PROCEDURE | root@localhost | 2019-02-28 13:00:02 | 2019-02-28 13:00:02 | DEFINER       |         | utf8                 | utf8_general_ci      | utf8_general_ci    |
+------+------+-----------+----------------+---------------------+---------------------+---------------+---------+----------------------+----------------------+--------------------+
1 row in set (0.01 sec)

          2.此时想到是用户没有当前存储过程的调用权限，赋予存储过程权限给当前用户，此时又出现了一个错误：

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%';
ERROR 1133 (42000): Can't find any matching row in the user table

           通过查询资料发现，需要先将当前的存储过程刷新，再执行授权语句：

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

mysql> GRANT ALL  PRIVILEGES ON test.*  TO 'root'@localhost;
Query OK, 0 rows affected (0.00 sec)

         3.再执行调用此存储过程，显示成功调用：

mysql> SHOW PROCEDURE STATUS;
+------+------+-----------+----------------+---------------------+---------------------+---------------+---------+----------------------+----------------------+--------------------+
| Db   | Name | Type      | Definer        | Modified            | Created             | Security_type | Comment | character_set_client | collation_connection | Database Collation |
+------+------+-----------+----------------+---------------------+---------------------+---------------+---------+----------------------+----------------------+--------------------+
| test | spl  | PROCEDURE | root@localhost | 2019-02-28 13:11:23 | 2019-02-28 13:11:23 | DEFINER       |         | utf8                 | utf8_general_ci      | utf8_general_ci    |
+------+------+-----------+----------------+---------------------+---------------------+---------------+---------+----------------------+----------------------+--------------------+
1 row in set (0.01 sec)

mysql> CALL spl;
