耿建玲视频看完了,个人认为其中讲的内容主要分为三大块,如下图所示:
首先是SQL SERVER 2000 的简介,包括SQL SERVER 2000的特点,版本,工具和实用程序(企业管理器,服务管理器,查询分析器,客户端网络使用工具,事件探查器,服务器网络使用工具,导入和导出数据,联机帮助文档),还有SQL SERVER 2000的安装,配置和升级,登录认证,对象,语句权限,数据的备份和恢复等。
其次就是表,视图,存储过程,索引,触发器,缺省值,规则,用户,图表等数据库对象利用企业管理器或T-SQL语句的增,删,改,查。
在进行增,删,改,查是所用到的T-SQL语句是我想说的第三部分,视频中介绍了T-SQL的语句,语法,数据类型,函数,全局和局部变量,运算符,控制流程,游标和事务等,还有子查询,联接查询,嵌套查询三种查询过程等.

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2.
