（1）查询SQLServer2005中某个数据库中的表结构
SELECT TOP 100 PERCENT --a.id,
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 dbo.sysindexes si INNER JOIN
dbo.sysindexkeys sik ON si.id = sik.id AND si.indid = sik.indid INNER JOIN
dbo.syscolumns sc ON sc.id = sik.id AND sc.colid = sik.colid INNER JOIN
dbo.sysobjects so ON so.name = si.name AND so.xtype = 'PK'
WHERE sc.id = a.id AND sc.colid = a.colid) THEN '√' ELSE '' END AS 主键,
b.name AS 类型, a.length AS 长度, COLUMNPROPERTY(a.id, a.name, 'PRECISION')
AS 精度, 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, d.crdate AS 创建时间,
CASE WHEN a.colorder = 1 THEN d.refdate ELSE NULL END AS 更改时间
FROM dbo.syscolumns a LEFT OUTER JOIN
dbo.systypes b ON a.xtype = b.xusertype INNER JOIN
dbo.sysobjects d ON a.id = d.id AND d.xtype = 'U' AND
d.status >= 0 LEFT OUTER JOIN
dbo.syscomments e ON a.cdefault = e.id LEFT OUTER JOIN
dbo.sysproperties g ON a.id = g.id AND a.colid = g.smallid AND
g.name = 'MS_Description' LEFT OUTER JOIN
dbo.sysproperties f ON d.id = f.id AND f.smallid = 0 AND
f.name = 'MS_Description'
ORDER BY d.name, a.colorder
PS：如若有的数据库中不存在dbo.sysproperties表，那么只需要将与之相关的注释掉即可。
最简单的查询用户表的SQL如下：
select * from sys.tables
（2）查询SQLServer2005中某个数据库中的索引
SELECT TOP 100 PERCENT --a.id,
CASE WHEN b.keyno = 1 THEN c.name ELSE '' END AS 表名,
CASE WHEN b.keyno = 1 THEN a.name ELSE '' END AS 索引名称, d.name AS 列名,
b.keyno AS 索引顺序, CASE indexkey_property(c.id, b.indid, b.keyno, 'isdescending')
WHEN 1 THEN '降序' WHEN 0 THEN '升序' END AS 排序, CASE WHEN p.id IS NULL
THEN '' ELSE '√' END AS 主键, CASE INDEXPROPERTY(c.id, a.name, 'IsClustered')
WHEN 1 THEN '√' WHEN 0 THEN '' END AS 聚集, CASE INDEXPROPERTY(c.id,
a.name, 'IsUnique') WHEN 1 THEN '√' WHEN 0 THEN '' END AS 唯一,
CASE WHEN e.id IS NULL THEN '' ELSE '√' END AS 唯一约束,
a.OrigFillFactor AS 填充因子, c.crdate AS 创建时间, c.refdate AS 更改时间
FROM dbo.sysindexes a INNER JOIN
dbo.sysindexkeys b ON a.id = b.id AND a.indid = b.indid INNER JOIN
dbo.syscolumns d ON b.id = d.id AND b.colid = d.colid INNER JOIN
dbo.sysobjects c ON a.id = c.id AND c.xtype = 'U' LEFT OUTER JOIN
dbo.sysobjects e ON e.name = a.name AND e.xtype = 'UQ' LEFT OUTER JOIN
dbo.sysobjects p ON p.name = a.name AND p.xtype = 'PK'
WHERE (OBJECTPROPERTY(a.id, N'IsUserTable') = 1) AND (OBJECTPROPERTY(a.id,
N'IsMSShipped') = 0) AND (INDEXPROPERTY(a.id, a.name, 'IsAutoStatistics') = 0)
ORDER BY c.name, a.name, b.keyno
（3）查询SQLServer2005中某个数据库中的主键、外键、约束、视图、存储过程、触发器以及自定义函数
SELECT DISTINCT
TOP 100 PERCENT o.xtype,
CASE o.xtype WHEN 'X' THEN '扩展存储过程' WHEN 'TR' THEN '触发器' WHEN 'PK' THEN
'主键' WHEN 'F' THEN '外键' WHEN 'C' THEN '约束' WHEN 'V' THEN '视图' WHEN 'FN'
THEN '函数-标量' WHEN 'IF' THEN '函数-内嵌' WHEN 'TF' THEN '函数-表值' ELSE '存储过程'
END AS 类型, o.name AS 对象名, o.crdate AS 创建时间, o.refdate AS 更改时间,
c.text AS 声明语句
FROM dbo.sysobjects o LEFT OUTER JOIN
dbo.syscomments c ON o.id = c.id
WHERE (o.xtype IN ('X', 'TR', 'C', 'V', 'F', 'IF', 'TF', 'FN', 'P', 'PK')) AND
(OBJECTPROPERTY(o.id, N'IsMSShipped') = 0)
ORDER BY CASE o.xtype WHEN 'X' THEN '扩展存储过程' WHEN 'TR' THEN '触发器' WHEN
'PK' THEN '主键' WHEN 'F' THEN '外键' WHEN 'C' THEN '约束' WHEN 'V' THEN '视图'
WHEN 'FN' THEN '函数-标量' WHEN 'IF' THEN '函数-内嵌' WHEN 'TF' THEN '函数-表值'
ELSE '存储过程' END DESC
（4）查询SQLServer2005中某个数据库中的所有关系图
select * from dbo.sysdiagrams
（5）查询SQLServer2005中某个数据库中的所有对象
select * from sys.sysobjects
不同的对象用xtype来标识。
C = CHECK 约束
D = 默认值或 DEFAULT 约束
F = FOREIGN KEY 约束
L = 日志
FN = 标量函数
IF = 内嵌表函数
P = 存储过程
PK = PRIMARY KEY 约束（类型是 K）
RF = 复制筛选存储过程
S = 系统表
TF = 表函数
TR = 触发器
U = 用户表
UQ = UNIQUE 约束（类型是 K）
V = 视图
X = 扩展存储过程
这些信息可以通过联机丛书->索引->sysobjects->xtype来查看。
