各位用户为了找寻关于获取MSSQL 表结构中字段的备注、主键等信息的sql的资料费劲了很多周折。这里教程网为您整理了关于获取MSSQL 表结构中字段的备注、主键等信息的sql的相关资料,仅供查阅,以下为您介绍关于获取MSSQL 表结构中字段的备注、主键等信息的sql的详细内容

1、MSSQL2000 

代码如下:

SELECT  表名 = case when a.colorder=1 then d.name else '' end,  表说明 = case when a.colorder=1 then isnull(f.value,'') else '' end,  字段序号 = a.colorder,  字段名 = a.name,  标识 = case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end,  主键 = 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,  类型 = b.name,  占用字节数 = a.length,  长度 = COLUMNPROPERTY(a.id,a.name,'PRECISION'),  小数位数 = isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0),  允许空 = case when a.isnullable=1 then '√'else '' end,  默认值 = isnull(e.text,''),  字段说明 = 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  sysproperties g  on  a.id=g.id and a.colid=g.smallid  left join  sysproperties f  on  d.id=f.id and f.smallid=0  where  d.name='FI_dept' --如果只查询指定表,加上此条件  order by  a.id,a.colorder 

2、MSSQL2005  use test--数据库  go  --2005实现字段属性统计(2000里的系统表sysproperties描述表、字段不存在,2005里用sys.extended_properties视图替代)  select  [表名]=c.Name,  [表说明]=isnull(f.[value],''),  [列名]=a.Name,  [列序号]=a.Column_id,  [标识]=case when is_identity=1 then '√' else '' end,  [主键]=case when exists(select 1 from sys.objects where parent_object_id=a.object_id and type=N'PK' and name in  (select Name from sys.indexes where index_id in  (select indid from sysindexkeys where and colid=a.column_id)))  then '√' else '' end,  [类型]=b.Name,  [字节数]=case when a.[max_length]=-1 and b.Name!='xml' then 'max/2G'  when b.Name='xml' then ' 2^31-1字节/2G'  else rtrim(a.[max_length]) end,  [长度]=ColumnProperty(a.object_id,a.Name,'Precision'),  [小数]=isnull(ColumnProperty(a.object_id,a.Name,'Scale'),0),  [是否為空]=case when a.is_nullable=1 then '√' else '' end,  [列说明]=isnull(e.[value],''),  [默认值]=isnull(d.text,'')  from  sys.columns a  left join  sys.types b on a.user_type_id=b.user_type_id  inner join  sys.objects c on a.object_id=c.object_id and c.Type='U'  left join  syscomments d on a.default_object_id=d.ID  left join  sys.extended_properties e on e.major_id=c.object_id and e.minor_id=a.Column_id and e.class=1  left join  sys.extended_properties f on f.major_id=c.object_id and f.minor_id=0 and f.class=1  [/code]  结果:
