For the following stored procedures, the table structure is as follows: -- ------------------------------ Table structure for person-- ----------------------------DROP TABLE IF EXISTS `person`;CREATE TABLE `person` ( `id` int(11) NOT NULL AUTO_INCREMENT, `username` varchar(255) DEFAULT NULL, `age` int(11) DEFAULT NULL, `password` varchar(255) DEFAULT NULL, PRIMARY KEY (`id`)) ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8;-- ---------------

You can use exec or call to call a written stored procedure in Oracle data, but you can only use call to call the stored procedure in db2. Pay attention to parameter issues and parameter issues. Exec proc_pay_idv ('20140901 ',?); The execution reports an error. exec

① Why should stored procedures be used?Because it is faster than SQL statement execution. ② What is a stored procedure?Combine a bunch of SQL statements and execute SQL statements without passing through the conditions.

that the code of the program becomes smaller and easier to understand. Another advantage of stored procedures is that SQL can be pre-compiled, which increases the speed of the program. Because stored procedures contain program logic, more processing can be performed on the database server. Similarly, when an n-tier program is executed, the stored
