  • 【数据操作】查看SqlServer数据表结构

    简单型:
    Select * from Syscolumns  Where ID=OBJECT_ID(N'Ebs_AdCustomer')

    列表型:
    sp_help 表

    详细型:
    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&nbsp; and d.xtype='U' and&nbsp; 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&nbsp;
    left join sysproperties f on d.id=f.id and f.smallid=0
    --where d.name='要查询的表'&nbsp; &nbsp; --如果只查询指定表,加上此条件
    order by a.id,a.colorder
