SQL SERVER 查看表说明，字段属性

查询表字段属性，说明等：

 1 SELECT
 2 表名=case when a.colorder=1 then d.name else '' end,
 3 表说明=case when a.colorder=1 then isnull(f.value,'') else '' end,
 4 字段序号=a.colorder,
 5 字段名=a.name,
 6 标识=case when COLUMNPROPERTY(a.id,a.name,'IsIdentity')=1 then '√'else '' end,
 7 主键=case when exists(SELECT 1 FROM sysobjects where xtype='PK' and name in (
 8   SELECT name FROM sysindexes WHERE indid in(
 9    SELECT indid FROM sysindexkeys WHERE id = a.id AND colid=a.colid
10    ))) then '√' else '' end,
11 类型=b.name,
12 占用字节数=a.length,
13 长度=COLUMNPROPERTY(a.id,a.name,'PRECISION'),
14 小数位数=isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0),
15 允许空=case when a.isnullable=1 then '√'else '' end,
16 默认值=isnull(e.text,''),
17 字段说明=isnull(g.[value],'')
18 FROM syscolumns a
19 left join systypes b on a.xtype=b.xusertype
20 inner join sysobjects d on a.id=d.id and d.xtype='U' and d.name<>'dtproperties'
21 left join syscomments e on a.cdefault=e.id
22 left join sys.extended_properties g on a.id=g.major_id and a.colid=g.minor_id
23 left join sys.extended_properties f on d.id=f.major_id and f.minor_id =0
24 where d.name='表名' --表名
25 order by a.id,a.colorder

只查询表字段说明：

 1 SELECT
 2     表名 = OBJECT_NAME(c.object_id),
 3     字段名称 = c.name,
 4     字段说明 = ex.value
 5 FROM
 6     sys.columns c
 7 LEFT OUTER JOIN
 8     sys.extended_properties ex
 9 ON
10     ex.major_id = c.object_id
11     AND ex.minor_id = c.column_id
12     AND ex.name = 'MS_Description'
13 WHERE
14     OBJECTPROPERTY(c.object_id, 'IsMsShipped')=0
15      AND OBJECT_NAME(c.object_id) = 'table_1'  -- 这里加上你的表名字

查询表在那个数据库：

1 exec sp_MSforeachdb @command1='USE ? if exists(SELECT 1 from sysobjects where id=object_id(''MemberInfo'')) PRINT ''?'''

查询字段在那些表：

1 select
2 sysobjects.name as tablename,
3 syscolumns.name as columnname
4 from syscolumns
5  join sysobjects on sysobjects.id = syscolumns.id
6 where syscolumns.name like '%ProductEntryId%'

查询字段在那些存储过程中：

1 SELECT obj.Name 存储过程名,
2  sc.TEXT 存储过程内容
3 FROM syscomments sc
4 INNER JOIN sysobjects obj ON sc.Id = obj.ID
5 WHERE sc.TEXT LIKE '%' + '字段名' + '%'
6 AND TYPE = 'P'
