邹建的代码sql2000可运行sql2005运行失败
------解决方案--------------------
SQL2005中應該用：sys.extended_properties
如：
SELECT
表名 = CASE WHEN A.COLORDER=1 THEN D.NAME ELSE ' ' END,
表說明 = CASE WHEN A.COLORDER=1 THEN ISNULL(F.VALUE, ' ') ELSE ' ' END,
欄位序號 = A.COLORDER,
欄位名 = A.NAME,
標識 = CASE WHEN COLUMNPROPERTY( A.ID,A.NAME, 'ISIDENTITY ')=1 THEN '√ 'ELSE ' ' END,
主鍵 = 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,
類型 = B.NAME,
佔用位元組數 = A.LENGTH,
長度 = COLUMNPROPERTY(A.ID,A.NAME, 'PRECISION '),
小數位數 = ISNULL(COLUMNPROPERTY(A.ID,A.NAME, 'SCALE '),0),
允許空 = CASE WHEN A.ISNULLABLE=1 THEN '√ 'ELSE ' ' END,
預設值 = ISNULL(E.TEXT, ' '),
欄位說明 = ISNULL(G.[VALUE], ' ')
FROM
SYSCOLUMNS A
LEFT JOIN
SYSTYPES B
ON
A.XUSERTYPE=B.XUSERTYPE
INNER JOIN
SYSOBJECTS D
ON
A.ID=D.ID AND D.XTYPE= 'U ' AND D.NAME <> 'DTPROPERTIES '
LEFT JOIN
SYSCOMMENTS E
ON
A.CDEFAULT=E.ID
LEFT JOIN
sys.extended_properties G
ON
A.ID=G.major_id AND A.COLID=G.minor_id
LEFT JOIN
sys.extended_properties F
ON
D.ID=F.major_id AND F.minor_id=0
ORDER BY
A.ID,A.COLORDER
