sqlserver有什么语句或函数我不太清楚,我自己写了一个,你可以试试,不过只能在2000上使用,7.0上得去掉字段的描述属性。select rtrim(b.name) as colname
,case when h.id is not null then 'PK' else '' end as primarykey
,type_name(b.xusertype) + case when b.colstat & 1 = 1 then '[ID(' + convert(varchar,ident_seed(a.name)) + ',' + convert(varchar,ident_incr(a.name)) + ')]' else '' end as type
,b.length
,case b.isnullable when 0 then 'N' else 'Y' end as [isnull]
,isnull(e.text,'') as [default]
,isnull(c.value,'') as descript
from sysobjects a,syscolumns b
left outer join sysproperties c on b.id = c.id and b.colid = c.smallid
left outer join syscomments e on b.cdefault = e.id
left outer join (select g.id,g.colid from sysindexes f,sysindexkeys g where f.id = g.id and f.indid = g.indid and f.indid > 0 and f.indid < 255 and (f.status & 2048)<>0) h on b.id = h.id and b.colid = h.colid
where a.id = b.id
and a.id = object_id('tablename') --tablename改成你要导出的表的名称
order by b.colid
,case when h.id is not null then 'PK' else '' end as primarykey
,type_name(b.xusertype) + case when b.colstat & 1 = 1 then '[ID(' + convert(varchar,ident_seed(a.name)) + ',' + convert(varchar,ident_incr(a.name)) + ')]' else '' end as type
,b.length

还有“识别字”是什么属性值?怎么我不知道还有这个属性,能不能说得明白点!
竹兄的取得表结构的存储过程真是精品,运行就能得到创建该表的语句,我已经收藏了。
不过对于“请问怎样得到up_getTableStruct的表结构的值?”这个问题,真是不知道怎么回答好。
我想怎么导入存储过程的问题,其实也应该是怎么创建这个存储过程吧!直接把“up_getTableStruct過程如下:”之后的sql语句拷到sqlserver的查询分析器中,运行就行了。
之后再在查询分析器中输入up_getTableStruct 'yourtable'就能得到表yourtable的表结构了。
在SQL Server中建好該存儲過程.
然後在VB中調用不就可以了???
比如用VB导出某个表的SQL语句(注意要在VB中引用SQLDMO):
Dim oSQLSERVER As New SQLDMO.SQLServer
oSQLSERVER.Connect "myserver", "sa", ""
Dim oTable As New SQLDMO.Table
Set oTable= bbb.Tables("t_bill")
oTable.Script SQLDMOScript_Default, "c:\abc.sql", "", SQLDMOScript2_UnicodeFile
set oTable=nothing
oSQLSERVER.close
set oSQLSERVER=nothing不知道你是不是要这个?上面的方法也很好,存储过程是在数据库里建好了的。你用时只需调用就行了。
Dim oSQLSERVER As New SQLDMO.SQLServer
oSQLSERVER.Connect "myserver", "sa", ""
Dim oTable As New SQLDMO.Table
Set oTable= oSQLSERVER.Tables("t_bill")
oTable.Script SQLDMOScript_Default, "c:\abc.sql", "", SQLDMOScript2_UnicodeFile
set oTable=nothing
oSQLSERVER.close
set oSQLSERVER=nothing
