  • SQL Server查询表结构

    SELECT (case when a.colorder=1 then d.name else null end) 表名,  
    a.colorder 字段序号,a.name 字段名,
    (case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then ''else '' end) 标识, 
    (case when (SELECT count(*) FROM sysobjects  
    WHERE (name in (SELECT name FROM sysindexes  
    WHERE (id = a.id) AND (indid in  
    (SELECT indid FROM sysindexkeys  
    WHERE (id = a.id) AND (colid in  
    (SELECT colid FROM syscolumns WHERE (id = a.id) AND (name = a.name)))))))  
    AND (xtype = 'PK'))>0 then '' else '' end) 主键,b.name 类型,a.length 占用字节数,  
    COLUMNPROPERTY(a.id,a.name,'PRECISION') as 长度,  
    isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0) as 小数位数,(case when a.isnullable=1 then ''else '' end) 允许空,  
    isnull(e.text,'') 默认值,isnull(g.[value], ' ') AS [说明]
    FROM  syscolumns a 
    left join systypes b on a.xtype=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.class and f.minor_id=0
    WHERE d.name='BUS_TransitSite' --如果只查询指定表,加上此条件
    order by a.id,a.colorder
