CountEmp ('James',out_value); dbms_output.put_line(out_value); end; 七、维护存储过程 • 修改存储过程:与创建的语法相同,使用REPLACE替换即可。 • 删除存储过程:drop procedure [schema.]过程名
存储过程(Stored Procedure),就是一组用于完成特定数据库功能的SQL语句集,该SQL语句集经过编译后存储在数据库系统中。这篇文章主要介绍了oracle中print_table存储过程介绍,需要的朋友可以参考下 定义 所谓存储过程(Stored Procedure),就是一组用于完成特定数据库功能的SQL语句集,该SQL语句集经过 编译后存储在数据库系统...
