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 b.name is not null
--WHERE d.name=‘要查询的表‘ --如果只查询指定表,加上此条件
order by a.id,a.colorder

sqlserver没有这样的功能,但你可以用powerdesigner等工具去建表,这个可以实现你要的,然后你在导到sqlserver就ok了热心网友 时间:2022-04-08 06:23
