To create a new database in MySQL Workbench, just go to “File -> Create Schema.” From there, you can begin building your new database. MySQL Workbench isn’t necessarily faster than MySQL. It just gives you a visual interface through which you can administer all your data. The command...

A database in MySQL is implemented as a directory containing files that correspond to tables in the database. Because there are no tables in a database when it is initially created, theCREATE DATABASEstatement creates only a directory under the MySQL data directory and thedb.optfile. Rules ...

MySQL数据系统与其它关系数据库一样,在需要使用该数据库之前,必须先创建数据库。之前已经提出过一个概念,就是任何程序都是四种语句状态:新增、查找、修改、删除。创建数据库当然属于第一种“新增”的语句状态。让我们先用 HELP ‘CREATE DATABASE’; 命令查看一下该语句的结构。
mysql> CREATE DATABASE test_db; Query OK, 1 row affected (0.12 sec); “Query OK, 1 row affected (0.12 sec);”提示中,“Query OK”表示上面的命令执行成功,“1 row affected”表示操作只影响了数据库中一行的记录,“0.12 sec”则记录了操作执行的时间。
数据库可以看作是一个专门存储数据对象的容器,这里的数据对象包括表、视图、触发器、存储过程等,其中表是最基本的数据对象。在MySQL数据库中创建数据对象之前,先要创建好数据库。 在MySQL 中,可以使用CREATE DATABASE语句创建数据库,语法格式如下: CREATE DATABASE [IF NOT EXISTS] <数据库名>[[DEFAULT] CHARACTER...
