摘要:获取表字段相关信息
SELECT 表名=case when a.colorder=1 then d.name else '' end,
字段序号=a.colorder,
字段名=a.name,
数据类型=b.name+'('+CONVERT(varchar(50),a.length)+')',
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,
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,''),
字段注释 = ex.value
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 OUTER JOIN sys.extended_properties ex on ex.major_id = a.id AND ex.minor_id = a.colid AND ex.name = 'MS_Description'
where d.name='green_ratio'
Order by a.id,a.colorder;
--其中,green_ratio为表名示例
执行结果如图:
