3个SQL视图搞定所有SqlServer数据库字典

　　网上有很多SQL Server数据库字典的SQL语句，七零八落，我在工作整理了一下思路，总结SQL代码如下，只在SQLSERVER2000中测试通过，希望对大家有帮助。

　　1. SqlServer数据库字典--表结构.sql

　　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 = so.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 LEFT OUTER JOIN

　　dbo.sysproperties f ON d.id = f.id AND f.smallid = 0

　　ORDER BY d.name, a.colorder

　　2. SqlServer数据库字典--索引.sql

　　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. SqlServer数据库字典--主键.外键.约束.视图.函数.存储过程.触发器.sql

　　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
