SQL 2005 字段备注获取

　　实际开发中经常为数据字段备注而烦恼，为此写了如下存储过程，一方便查看数据库备注信息.

 1  

 2 create proc [dbo].[GenerateDataDictionaryByTableName]

 3 @tableName  nvarchar(255)

 4 as

 5 begin

 6 --获取数据表名

 7 declare  @tableid int

 8 declare mycursor Cursor

 9 for select object_id from sys.objects where type='U' and  name<>'dtproperties' and name LIKE '%'+ @tableName+'%'

10 --获取字段名称、标识、字段序号、占用字节数、小数位数、允许空等

11 open mycursor

12 fetch next from mycursor into @tableid

13 while(@@fetch_status=0) 

14 begin 

15     SELECT object_name(@tableid) AS 表名,VALUE AS 表说明 FROM sys.extended_properties 

16     WHERE NAME='MS_Description' AND MAJOR_ID=@tableid AND MINOR_ID=0;

17     select 

18         col.colorder 字段序号,

19         col.name 字段名,

20         t.name 类型,

21         col.length 占用字节数,

22         COLUMNPROPERTY(col.id,col.name,'PRECISION') as 长度,

23         isnull(COLUMNPROPERTY(col.id,col.name,'Scale'),0) as 小数位数,

24         (case when 

25             (SELECT count(*)

26                 FROM sysobjects

27                 WHERE (name in

28                     (SELECT name

29                         FROM sysindexes

30                         WHERE (id = col.id) 

31                             AND (indid in

32                                     (SELECT indid

33                                      FROM sysindexkeys

34                                      WHERE (id = col.id) AND (colid in

35                                             ( SELECT colid

36                                               FROM syscolumns

37                                               WHERE (id = col.id)

38                                                     AND (name = col.name)

39                                               ))

40                                      )

41                                   )

42                    )) AND

43                    (xtype = 'PK')

44               )>0 

45          then '√' else '' end) 主键,

46         (case when COLUMNPROPERTY(col.id,col.name,'IsIdentity')=1 then '√'else '' end) 标识,

47         (case when col.isnullable=1 then '√'else '' end) 允许空,

48         isnull(expro.[value],'') AS 字段说明

49     from sys.syscolumns as col

50     left join sys.systypes as t on col.xtype = t.xusertype

51     left join sys.extended_properties as expro on col.id=expro.major_id AND col.colid = expro.minor_id

52     where id = @tableid 

53     fetch next from mycursor into @tableid

54 end

55 close mycursor

56 deallocate mycursor 

57 end

　　在需要查看指定表描述时，输入如下语句：

exec [GenerateDataDictionaryByTableName] N'T_INTE_'

该存储过程会搜索当前数据库中表名包含传入的参数字符串，并返回符合条件的所有表的备注信息。如下返回形如：
