查看SQL表的详细信息

给大家分享个查看sqlserver数据库中表的详细信息的sql语句（语句来自动软），虽然没有很复杂的技术，但是在sqlserver数据库中能够非常方便的看表的详细结构；结果图如下：

我把它写成了存储过程，调用存储过程时，参数是表名，这样在开发中会给我们一定的帮助

另说明：本方法使用与SQL2000数据库

create proc getTable

@tabName varchar(50) =null

as

SELECT 

    表名=case a.colorder when 1 then d.name else '' end,

    序号=a.colorder,

    列名=a.name,

    类型=b.name, 

    长度=CASE WHEN b.name='nchar' THEN a.length/2 WHEN b.name='nvarchar' THEN a.length/2 ELSE a.length END,

    精度=COLUMNPROPERTY(a.id,a.name,'PRECISION'), 

    小数=isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0), 

    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 name in (SELECT name FROM sysindexes WHERE indid in( SELECT indid FROM sysindexkeys WHERE id = a.id AND colid=a.colid ))) then '√' else '' end, 

    允许空=case when a.isnullable=1 then '√'else '' end, 

    默认值=isnull(e.text,''), 

    列说明=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' or d.xtype='V') 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 

where d.name=@tabName or @tabName is null

order by d.name,a.colorder

相信大家都会使用的吧
