1. 打开 Navicat, 新建查询, 执行下列语句查询 MySQ L数据库表结构信息,复制到 Excel, 后续你可以自己处理分组:
SELECTCONCAT_WS(' : ',t.table_name,t.table_comment) AS '表名',sc.column_name AS '字段名称',sc.column_type AS '数据类型',sc.data_type AS '字段类型',sc.character_maximum_length AS '长度',sc.is_nullable AS '是否为空',sc.column_default AS '默认值',sc.column_comment AS '备注',sc.column_key AS '约束',c.referenced_table_name AS '父表名称',c.referenced_column_name AS '父表字段',c.constraint_name AS '约束名'FROMinformation_schema.COLUMNS sc JOIN information_schema.TABLES t ON sc.table_name = t.TABLE_NAME JOIN information_schema.KEY_COLUMN_USAGE c ON t.TABLE_NAME = c.table_nameWHEREsc.table_schema = '数据库名称'
2. 也可以开启mysql导入与导出的目录权限, 打开f配置文件,改为:
secure-file-priv = '/tmp/目录'
如果没有 my.conf ,终端登录管理员,
vim /private/etc/f写入:[mysqld]secure_file_priv='/tmp/mysql_out'
secure_file_prive说明:
secure_file_prive=null， //不允许导入导出
secure_file_priv=目录，//只能在指定目录下导入导出
secure_file_priv=' '，//不对导入导出做限制
另外mac下要把目录设在'tmp'下, 不然MySQL要么报错要么无法重启,
还要给mysql 用户写入权限,
例如 :
f 设置目录: secure-file-priv = '/tmp/mysql_out'
赋权: chown _mysql:_mysql /private/tmp/mysql_out
然后系统偏好设置里重启 MySQL 之后, 执行:
SHOW VARIABLES LIKE "secure_file_priv";
看到设置目录即为成功
然后执行下列语句即可 直接导出 xls
SELECTCONCAT_WS(' : ',t.table_name,t.table_comment) AS '表名',sc.column_name AS '字段名称',sc.column_type AS '数据类型',sc.data_type AS '字段类型',sc.character_maximum_length AS '长度',sc.is_nullable AS '是否为空',sc.column_default AS '默认值',sc.column_comment AS '备注',sc.column_key AS '约束',c.referenced_table_name AS '父表名称',c.referenced_column_name AS '父表字段',c.constraint_name AS '约束名'FROMinformation_schema.COLUMNS sc JOIN information_schema.TABLES t ON sc.table_name = t.TABLE_NAME JOIN information_schema.KEY_COLUMN_USAGE c ON t.TABLE_NAME = c.table_nameWHEREsc.table_schema = 'meditation' INTO OUTFILE '导出到哪个目录/XXX.xls'
