master数据库里的哪个表存储了用户表的数据结构

请问：master数据库里的哪个表存储了用户表的数据结构？
如果可以的话，请把master数据库里的所有表里存储的什么内容都告诉我。
谢谢！！

Answer 1

sysobjects 存储的是表和各种对象信息。
syscolumns 存储的是字段信息。
两个表联合就能得到表结构信息了。

select a.name,b.name, a.*,b.* from sysobjects a , syscolumns b
where a.type = 'u'
and a.id = b.id
order by a.id , b.colid

Answer 2

表名:sysobjects

例:
SELECT CASE WHEN a.colorder = 1 THEN d.name ELSE '' END AS 表名,
CASE WHEN a.colorder = 1 THEN isnull(f.value, '') ELSE '' END AS 表说明,
a.colorder AS 字段序号, a.name AS 字段名, CASE WHEN COLUMNPROPERTY(a.id,
a.name, 'IsIdentity') = 1 THEN '√' ELSE '' END AS 标识,
CASE WHEN EXISTS
(SELECT 1
FROM sysobjects
WHERE xtype = 'PK' AND name IN
(SELECT name
FROM sysindexes
WHERE indid IN
(SELECT indid
FROM sysindexkeys
WHERE id = a.id AND colid = a.colid)))
THEN '√' ELSE '' END AS 主键, b.name AS 类型, a.length AS 占用字节数,
COLUMNPROPERTY(a.id, a.name, 'PRECISION') AS 长度,
ISNULL(COLUMNPROPERTY(a.id, a.name, 'Scale'), 0) AS 小数位数,
CASE WHEN a.isnullable = 1 THEN '√' ELSE '' END AS 允许空, ISNULL(e.text, '')
AS 默认值, ISNULL(g.[value], '') AS 字段说明
FROM syscolumns a LEFT OUTER JOIN
systypes b ON a.xtype = b.xusertype INNER JOIN
sysobjects d ON a.id = d.id AND d.xtype = 'U' AND
d.name <> 'dtproperties' LEFT OUTER JOIN
syscomments e ON a.cdefault = e.id LEFT OUTER JOIN
sysproperties g ON a.id = g.id AND a.colid = g.smallid LEFT OUTER JOIN
sysproperties f ON d.id = f.id AND f.smallid = 0
ORDER BY a.id, a.colorder
