Consider one table tbl1 with ID and Name.
A table-valued parameter params with ID.

I need to duplicate the rows in tbl1 which have the ID contained in params.
I am trying to insert like this

insert into tbl1(Name,somevalues..) 
   select tbl1.Name, tbl1.somevalues..
   from @params p 
   inner join tbl1 on tbl1.ID=p.ID  -- here ID is identity (PK).

But after insertion, it is found that the order of insertion is different. If I am running the select query alone, it will display the ID based on @params (TVP). But the same query when I used after insert will perform in a different way.

order in TVP / Select Query – A
order when insert using Select Query – B

 A       B 
370294  370294
368702  368702
369157  368504
368914  368505
368505  368914
368504  369157
368508  368506
368506  368507
368507  368508
368912  368637
368637  368638
368638  368639
368639  368912
368915  368915
368641  368641

There some ID’s which are different in order.

What will be the issue for different order?

How can I insert values in the same order as in my TVP ?

Thanks in advance.

    Always: ORDER is arbitrary without an ORDER BY.

    This means that even if you did use ORDER BY for the INSERT, then a later SELECT isn’t guaranteed to return with this order unless you use ORDER BY on the SELECT.

    In other words: there is no implied or natural order to a table or view.

    You can only have a defined order with ORDER BY

    Edit

    However. it should be noted that INNER JOINs are both commutative and associative. That is, you get the same results. You’re asking about ORDER which I answered above
