Thanks

You can see the statistics by running dbcc show_statistics (you can read about it BOL which is the help that is installed when you install SQL Server’s client tools). As much as I know you can only see the statistics or use UPDATE STATISTICS statement (again, you can see details about it in BOL) to update the statistics on a table or view, but you can not insert your own statistics that were taken from a different server.

Thanks Adi for your reply.

I don't want to transfer the statistics number but just the definition on the ones created with the "create statistics" command. Some statistics were create and I would like to replicate the definition on another database.

Thanks

create view dbo.v_stat as

select c.name as ColumnName, sc.stats_column_id, s.name as StatName, OBJECT_NAME(sc.object_id) as TblName

from sys.stats_columns sc

inner join sys.columns c on sc.column_id = c.column_id and sc.object_id = c.object_id

inner join sys.stats s on s.stats_id = sc.stats_id and sc.object_id = s.object_id

left outer join sys.indexes i on i.index_id = s.stats_id and i.object_id = s.object_id

where i.name is null

go

select distinct 'CREATE STATISTICS [' + v.StatName + '] on dbo.' + v.TblName + '(' + a.Fields + ');'

from dbo.v_stat v

join (select Fields = replace ((select ColumnName as 'data()'

from dbo.v_stat where StatName = s.StatName

for xml path('')), ' ',','),

s.StatName

from dbo.v_stat s

group by s.StatName) as a on a.StatName = v.StatName;

Rem,

I guess I understood your question. You want to create a statistics only database right?

That means, you don't want to worry about the underlying data but just the statistics so that you

could simulate a similar database environment.

Well, if you are looking for this, this is possible and some people refer to it as database cloning.

For more details, you could refer this link below, which is very useful.

http://support.microsoft.com/default.aspx?scid=kb;EN-US;914288

With this, we could clone a database without having to worry about the data. We would be able to simulate the same conditions as in the original database. The prerequisite is you need to have atleast SQL Server 2005 SP2 and above.
