本文主要介绍了一个获取SQL Server数据字典的经典SQL语句，大家可以根据各自的实际情况对这段语句进行相应的修改。

以下为引用的内容：
SELECT sysobjects.name AS [table], sysproperties.[value] AS 表说明,
syscolumns.name AS field, properties.[value] AS 字段说明,
systypes.name AS type,
syscolumns.length, ISNULL(COLUMNPROPERTY(syscolumns.id,
syscolumns.name,
'Scale'), 0) AS 小数位数, syscolumns.isnullable AS isnull,
CASE WHEN syscomments.text IS NULL
THEN '' ELSE syscomments.text END AS [Default],
CASE WHEN COLUMNPROPERTY(syscolumns.id, syscolumns.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 = syscolumns.id AND colid = syscolumns.colid)))
THEN '√' ELSE '' END AS 主键
FROM syscolumns INNER JOIN
sysobjects ON sysobjects.id = syscolumns.id INNER JOIN
systypes ON syscolumns.xtype = systypes.xtype LEFT OUTER JOIN
sysproperties properties ON syscolumns.id = properties.id AND
syscolumns.colid = properties.smallid LEFT OUTER JOIN
sysproperties ON sysobjects.id = sysproperties.id AND
sysproperties.smallid = 0 LEFT OUTER JOIN
syscomments ON syscolumns.cdefault = syscomments.id
WHERE (sysobjects.xtype = 'U')
