step 3: 在CloneServer 上创建执行克隆任务的存储过程
create procedure tableClone
@table nvarchar(1000)
As
begin
declare @sql nvarchar(4000);
declare @cols nvarchar(4000);
set @cols=''
execute [SarahCla].master.dbo.SP_GET_TABLE_INFO @table, @sql output, @cols output;
--SarahCla记得改成自己的linkserver name
--master 改成自己要克隆的表所在库的名称
execute sp_executesql @sql;
set @sql = ' set identity_insert tb3 on; insert into ' + @table + '(' + @cols + ')
select ' + @cols + ' From [SarahCla\Sarahcla2008].master.dbo.' + @table + ' set identity_insert ' + @table + ' off '
execute sp_executesql @sql;
end
step 4: 克隆表
例如:要克隆 tb3
execute tableClone 'tb3'
,如果要克隆所有表,遍历sysobjects执行哈,这里就不写了。。。(懒人一个)
