Workench 是官发发布的 Mysql 客户端,下载地址:http://cdn.mysql.com//Downloads/MySQLGUITools/mysql-workbench-community-6.3.8-1.el7.x86_64.rpm

Workench 安装

rpm -ivh mysql-workbench-community-6.3.8-1.el7.x86_64.rpm

# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

  • tinyxml 需要配置 EPEL
yum install epel-release.noarch
  • 安装 tinyxml
yum install tinyxml
  • 安装 libzippython-paramikoproj
yum install libzip python-paramiko proj.x86_64
  • 安装 unixODBC 解决 libodbc.so.2libodbcinst.so.2 依赖问题
yum install unixODBC
rpm -ivh postgresql-libs-9.3.4-1.el7.x86_64.rpm
  • 安装 Workench 成功
rpm -ivh mysql-workbench-community-6.3.8-1.el7.x86_64.rpm
  • Workench 建表的基本字段类型标识
标识 名称 说明
PK primary key 主键
NN not null 非空
UQ unique 唯一索引
BIN binary 二进制数据(比 text 更大)
UN unsigned 无符号(非负数)
ZF zero fill 填充 0,字段内容是 1 int(4),内容显示为0001。
AI auto increment 自增
G Generated 函数索引
  • Generated 函数索引

Generated ColumnMySQL 5.7 引入的新特性,这一列由其他列计算而得。例如:已知直角三角形的两条直角边,要求斜边的长度。斜边的长度可以通过两条直角边计算而得,在数据库中只存放直角边,斜边使用 Generated ColumnGenerated Column 分为 Virtual ColumnStored Column,默认为 Virtual Column,前者只将 Generated Column 保存在数据字典中(表的元数据),并不会将这一列数据持久化到磁盘上;后者会将 Generated Column 持久化到磁盘上,而不是每次读取的时候计算所得。后者存放了可以通过已有数据计算而得的数据,需要更多的磁盘空间。

  • Generated 函数索引的限制

    • 不能给 virtual column 插入数据。
    • 聚集索引不能包含 virtual column
    • 不能在 Virtual Column 上创建全文索引和空间索引。
    • Virtual Column 不能作为外键。
    • 创建 Generated Column (包括 Virtual Column 和 Stored Column)时不能使用非确定性的(不可重复的)函数。
    • Generated Column 定义为 x列 / 0,插入数据报错(ERROR 1365 (22012): Division by 0)。
    • Generated Column 定义为 x列 / y列,插入恶意数据,y列为 0,报错(ERROR 1365 (22012): Division by 0)。
    • Generated Column 定义为 x列 / y列,删除源列 x 或 y,报错(ERROR 3108 (HY000): Column 'x' has a generated column dependency.)
