用Navicat生成数据字典的方法

SELECT
t.TABLE_NAME AS 表名,
t.COLUMN_NAME AS 字段名,
t.COLUMN_TYPE AS 数据类型,
CASE IFNULL(t.COLUMN_DEFAULT,'Null')
WHEN '' THEN '空字符串'
WHEN 'Null' THEN 'NULL'
ELSE t.COLUMN_DEFAULT END AS 默认值,
CASE t.IS_NULLABLE WHEN 'YES' THEN '是' ELSE '否' END AS 是否允许为空,
t.COLUMN_COMMENT AS 字段说明
FROM information_schema.COLUMNS t
WHERE t.TABLE_SCHEMA='youlu_evaluate' AND t.TABLE_NAME='eva_question';

查询出相应的结果，直接导出为相应的格式即可。如Excel,CSV等
