     本文主要介绍了三个实用的SQL Server数据库字典SQL语句,数据库字典主要包括表结构(分为SQL Server 2000和SQL Server 2005)、索引和主键. 外键.约束.视图.函数.存储过程.触发器。你可以在查询分析器、企业管理器中简单执行后,快速的查出SQL Server 2000及SQL Server 2005的全部数据字典。

1. SQL Server 2000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 = 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

◆SQL Server 2005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 = 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
