使用Navicat導出數據字典

1.打開navicat，Ctrl+q快捷鍵新建查詢並執行

USE information_schema;

SELECT
	C.TABLE_SCHEMA AS '數據庫名',
	C.TABLE_NAME AS '表名',
	C.COLUMN_NAME AS '字段名',
	C.COLUMN_TYPE AS '數據類型',
	C.IS_NULLABLE AS '允許爲空',
	C.COLUMN_COMMENT AS '字段說明'
FROM
	COLUMNS C
INNER JOIN TABLES T ON C.TABLE_SCHEMA = T.TABLE_SCHEMA
AND C.TABLE_NAME = T.TABLE_NAME
WHERE
	T.TABLE_SCHEMA = 'xxx'
--and T.TABLE_NAME='tableName' 
--xxx這裏爲數據庫名
