获取SQLServer的最完整数据字典的SQL语句

其实网上已经流传了很多关于获取SQLServer的数据字典的版本，不过我相信这个应该是最全的了，本语句包括了表、字段、字段类型、字段长度、是否为空、是否递增字段、索引名称、索引的定位、索引类型、主键、外键等；通过合理的裁剪可以很方便的生成相应的数据字典。

SELECT

sysobjects.name AS 表名称,
--sysproperties.[value] AS 表说明,
syscolumns.name AS 字段名称,
--properties.[value] AS 字段说明,
systypes.name AS 字段类型,
syscolumns.length AS 字段长度,
ISNULL(COLUMNPROPERTY(syscolumns.id, syscolumns.name,'Scale'), 0) AS 小数位数,

CASE WHEN syscolumns.isnullable=0
THEN ''
ELSE '√'
END AS 是否为空,
CASE WHEN syscomments.text IS NULL
THEN '' ELSE syscomments.text
END AS 缺省值,
CASE WHEN COLUMNPROPERTY(syscolumns.id, syscolumns.name, 'IsIdentity')= 1
THEN '√' ELSE ''
END AS 递增字段,
CASE WHEN sysindexes.name IS NULL
THEN ''
ELSE sysindexes.name
END AS 索引名称,
CASE WHEN sysindexkeys.keyno IS NULL
THEN ''
ELSE CONVERT(VARCHAR(10),sysindexkeys.keyno )
END AS 索引位置,
CASE WHEN sysindexes.indid=1
THEN '聚集索引'
WHEN sysindexes.indid>1 AND sysindexes.indid<>255
THEN '非聚集索引'
WHEN sysindexes.indid IS NULL
THEN ''
ELSE
'其他'
END AS 索引类型,
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,
CASE WHEN sysforeignkeys.constid IS NULL
THEN ''
ELSE '√'
END AS 外健
FROM syscolumns                             --数据表字段

LEFT OUTER JOIN sysproperties                 --表属性信息

order by sysobjects.id,syscolumns.colid
