【oracle】oracle表结构导出到Word

因为需要写数据库文档，所以需要把数据库里边的表结构在word中用表格列出来，之前一直用powerdesigner，感觉有些麻烦，后来在网上找到了一段sql语句，经测试完全符合我的需求，不敢独享，语句如下： 

SELECT t1.Table_Name AS "表名称",
t3.comments AS "表说明", 
t1.Column_Name AS "字段名称",
t1.Data_Type AS "数据类型",
t1.Data_Length AS "长度",
t1.NullAble AS "是否为空",
t2.Comments AS "字段说明",
t1.Data_Default "默认值"
FROM cols t1 left join user_col_comments t2
on t1.Table_name=t2.Table_name and t1.Column_Name=t2.Column_Name
left join user_tab_comments t3 
on t1.Table_name=t3.Table_name 
WHERE NOT EXISTS ( SELECT t4.Object_Name FROM User_objects t4
WHERE t4.Object_Type='TABLE' 
AND t4.Temporary='Y' 
AND t4.Object_Name=t1.Table_Name )
ORDER BY t1.Table_Name, t1.Column_ID;

查询完成后，粘贴指定的列即可
