Passing Table Valued parameter to stored procedure across different databases

Question

I\'m using SQL Server 2008.

How can I pass Table Valued parameter to a Stored procedure across different D

Answer 1

Table UDTs are only valid for stored procs within the same database.

So yes you would have to create the type on each server and reference it in the stored procs - e.g. just run the first part of this example in both DBs http://msdn.microsoft.com/en-us/library/bb510489.aspx.

If you don't need the efficency you can always use other methods - i.e. pass an xml document parameter or have the s.p. expect a temp table with the input data.

Edit: added example

create database Test1
create database Test2
go
use Test1
create type PersonalMessage as TABLE
(Message varchar(50))
go
create proc InsertPersonalMessage @Message PersonalMessage READONLY AS
  select * from @Message
go
use Test2
create type PersonalMessage as TABLE
(Message varchar(50))
go
create proc InsertPersonalMessage @Message PersonalMessage READONLY AS
  select * from @Message
go
use Test1
declare @mymsg PersonalMessage
insert @mymsg select 'oh noes'
exec InsertPersonalMessage @mymsg 
go
use Test2
declare @mymsg2 PersonalMessage
insert @mymsg2 select 'oh noes'
exec InsertPersonalMessage @mymsg2 

Disadvantage is that there are two copies of the data. But you would be able to run the batch against each database simultaneously. Whether this is any better than using a table table is really down to what processing/data sizes you have - btw to use a temp table from an s.p. you just access it from the s.p. code (and it fails if it doesn't exist).
