SQL SERVER中查看一个数据库的表结构及字段

例如查看SQL Server自带的数据库ReportServer

  •  
  • SQL 代码   复制
  • 
    use ReportServer
    go
    
    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  
    sys.extended_properties   g   
    on  
        a.id=G.major_id and a.colid=g.minor_id   
    left join  
      
    sys.extended_properties f   
    on  
        d.id=f.major_id and f.minor_id=0   
    -- where d.name='C_PARTY_SPREADER'    --如果只查询指定表,加上此条件   
    order by  
        a.id,a.colorder
