看一下这个很酷的视图，zj写的，问一下，表的说明在哪里维护？

CREATE VIEW dbo.dbInfo
AS
SELECT TOP 100 PERCENT 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 sysobjects
WHERE xtype = 'PK' AND parent_obj = a.id AND name IN
(SELECT name
FROM sysindexes
WHERE indid IN
(SELECT indid
FROM sysindexkeys
WHERE id = a.id AND colid = a.colid)))
THEN '√' ELSE '' END AS 主键, b.name AS 类型, a.length AS 占用字节数,
COLUMNPROPERTY(a.id, a.name, 'PRECISION') AS 长度,
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
FROM dbo.syscolumns a LEFT OUTER JOIN
dbo.systypes b ON a.xusertype = b.xusertype INNER JOIN
dbo.sysobjects d ON a.id = d.id AND d.xtype = 'U' AND
d.name <> 'dtproperties' 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.id, a.colorder
