- 只复制一个表结构,不复制数据
select top 0 * into [t1] from [t2]
或者 select * into a from b where 1=2;
2.获取数据库中某个对象的创建脚本
if exists(select 1 from sysobjects where id=object_id('fgetscript') and objectproperty(id,'IsInlineFunction')=0)
drop function fgetscript
go
create function fgetscript(
@servername varchar(50) --服务器名
,@userid varchar(50)='sa' --用户名,如果为nt验证方式,则为空
,@password varchar(50)='' --密码
,@databasename varchar(50) --数据库名称
,@objectname varchar(250) --对象名
) returns varchar(8000)
as
begin
declare @re varchar(8000) --返回脚本
declare @srvid int,@dbsid int --定义服务器、数据库集id
declare @dbid int,@tbid int --数据库、表id
declare @err int,@src varchar(255), @desc varchar(255) --错误处理变量
--创建sqldmo对象
exec @err=sp_oacreate 'sqldmo.sqlserver',@srvid output
if @err<>0 goto lberr
--连接服务器
if isnull(@userid,'')='' --如果是 Nt验证方式
begin
exec @err=sp_oasetproperty @srvid,'loginsecure',1
if @err<>0 goto lberr
exec @err=sp_oamethod @srvid,'connect',null,@servername
end
else
exec @err=sp_oamethod @srvid,'connect',null,@servername,@userid,@password
if @err<>0 goto lberr
--获取数据库集
exec @err=sp_oagetproperty @srvid,'databases',@dbsid output
if @err<>0 goto lberr
--获取要取得脚本的数据库id
exec @err=sp_oamethod @dbsid,'item',@dbid output,@databasename
if @err<>0 goto lberr
--获取要取得脚本的对象id
exec @err=sp_oamethod @dbid,'getobjectbyname',@tbid output,@objectname
if @err<>0 goto lberr
--取得脚本
exec @err=sp_oamethod @tbid,'script',@re output
if @err<>0 goto lberr
--print @re
return(@re)
lberr:
exec sp_oageterrorinfo NULL, @src out, @desc out
declare @errb varbinary(4)
set @errb=cast(@err as varbinary(4))
exec master..xp_varbintohexstr @errb,@re out
set @re='错误号: '+@re
+char(13)+'错误源: '+@src
+char(13)+'错误描述: '+@desc
return(@re)
end
go
先执行上述脚本
print dbo.fgetscript('服务器名','用户名','密码','数据库名','表名或其它对象名')
然后按上语句执行即可。。
3. 获取所有数据库里所有对象的脚本
declare @name varchar(250)
declare #aa cursor for
select name from sysobjects where xtype not in('S','PK','D','X','L')
open #aa
fetch next from #aa into @name
while @@fetch_status=0
begin
print dbo.fgetscript('onlytiancai','sa','sa','database',@name)
fetch next from #aa into @name
end
close #aa
deallocate #aa
4.怎样获取一个表中所有的字段信息
Create view fielddesc
as
select o.name as table_name,c.name as field_name,t.name as type,c.length as
length,c.isnullable as isnullable,convert(varchar(30),p.value) as desp
from syscolumns c
join systypes t on c.xtype = t.xusertype
join sysobjects o on o.id=c.id
left join sysproperties p on p.smallid=c.colid and p.id=o.id
where o.xtype='U'
先执行上述SQL语句
Select * from fielddesc where table_name = '你的表名'
然后按上述的方法操作即可。。
5。当前数据库所有表的字段信息
SELECT
(case when a.colorder=1 then d.name else '' end) N'表名',
a.colorder N'字段序号',
a.name N'字段名',
(case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end) N'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) N'主键',
b.name N'类型',
a.length N'占用字节数',
COLUMNPROPERTY(a.id,a.name,'PRECISION') as N'长度',
isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0) as N'小数位数',
(case when a.isnullable=1 then '√'else '' end) N'允许空',
isnull(e.text,'') N'默认值',
isnull(g.[value],'') AS N'字段说明'
--into ##tx
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 sysproperties g
on a.id=g.id AND a.colid = g.smallid
order by object_name(a.id),a.colorder
