Views Across Databases On The Same Server
Apr 25, 2000
I have two databases on my Server - database1 and database2.
Database1 has a view on tables on database2 :
create view myview as select * from database2.dbo.tablename
(because all tables in database2 are owned by dbo)
and myview on database1 is owned by dbo.
when a user on database1 - lets say user1 tries to select rows from myview,
we get an error saying that user1 is not a valid user on database2.
it only allows user1 to select rows from myview if i make user1 a user on database2
as well, which is not what i want.
Can someone please point me in the right direction.
i would like to be able to select rows from a view which is based on tables in another database.
thanks

Hi,I am trying to locate documentation on using views across databases.We have serveral databases broken down by application, some shareddatabases and some location specific databases supporting multiplefacilities using the applications. The DBA for our client is the onethat set up the topology of these databases but I don't understand theperformance considerations of having views in an applictation databasereferencing tables in the shared databases. Is the enitre tablecopied to tempdb when the view is referenced? How does indexing inthe containing database affect access through the view? These aresome of the questions I would like see documenation on.Thanks,Jim

Hi,
We are migrating to SQL Server 2005 from 2000 and we have a view created in many of our databases. That view must be changed after the migration because it uses system tables and does not return the correct information in SQL Server 2005.
To do that, I want to create an SSIS-package that loops through all the databases on a particular server. If that view exists in the database, I want to run a script that change the view.
What I try to do:
Set up a For Each Loop container with Foreach SMO Enumerator
Set the connection to my server
Set the Enumerate property to "SMOEnumObj[@Name='Databases']/SMOEnumType[@Name='Names']"
On the Variable Mapping page, place Index 0 in Variable User::dbName
In the For Each Loop, place a script task to msgbox the value of User::dbName
This all works good. The problem comes when I try to nest the For Each Loop
Inside the "For Each Database Loop", place a new For Each Loop container with Foreach SMO Enumerator
I connect the Msgbox Script Task with the new For each loop
Use the same connection
Set the EnumURN property in the Expression Builder to "Database[@Name='" + @[User::dbName] +"']/SMOEnumObj[@Name='Views']/SMOEnumType[@Name='Names']"
On the Variable Mapping page, place index 0 in Variable User::tabName
In the For Each Loop, place a script task to msgbox the value of User::tabName
When I try to run the package now, it does not at all.
In my Progress tab I see that Validation has started and completed for each task, but I see now errors. Nothing has run.
Test 1: I change the DelayValidation for the Inner Loop to True
Now the package runs, but I never get to the script task in the inner loop.
Question 1: What's the problem?
Question 2: Is there another way to do this?
Regards
Magnus

Hi everybody.
I need to find all the views that depend on a table in a different database, in order to refresh them once the table is altered.
In the BOL I found the following script that is very useful, but I can't use it if the view and the table are in different database.
Where can I find the dependencies in this case?
Thank you very much.

I am moving a fairly large app from Access 2003 to C#/SQL Server 2005.
The app has one front end mde, but it has two backend data mdbs, one is used in the US and one in the UK.
The two backend mdb's are identical in structure, but of course the data is different. There are 150 tables or so, and we plan to maintain separate databases after the upgrade.
Now, of course, all of the queries are in the front end, the backend db's contain only tables.
In the new world, I do not want to have to maintain the same views and stored procs in two different SQL Server databases.
Is there a way to have all views and stored procs in one database, but have them draw on the data in the two other databases. There must should be a way to deal with this scenario in SQL Server.
Many thanks
Mike Thomas

Fellow database developers,I would like to draw on your experience with views. I have a databasethat includes many views. Sometimes, views contains other views, andthose views in turn may contain views. In fact, I have some views inmy database that are a product of nested views of up to 6 levels deep!The reason we did this was.1. Object-oriented in nature. Makes it easy to work with them.2. Changing an underlying view (adding new fields, removing etc),automatically the higher up views inherit this new information. Thismake maintenance very easy.3. These nested views are only ever used for the reporting side of ourapplication, not for the day-to-day database use by the application.We use Crystal Reports and Crystal is smart enough (can't believe Ijust said that about Crystal) to only pull back the fields that arebeing accessed by the report. In other words, Crystal will issue aSelect field1, field2, field3 from ReportingView Where .... eventhough "ReportingView" contains a long list of fields.Problems I can see.1. Parent views generally use "Select * From childview". This meansthat we have to execute a "sp_refreshview" command against all viewswhenever child views are altered.2. Parent views return a lot of information that isn't necessarilyused.3. Makes it harder to track down exactly where the information iscoming from. You have to drill right through to the child view to seethe raw table joins etc.Does anyone have any comments on this database design? I would love tohear your opinions and tales from the trenches.Best regards,Rod.

Which is more efficient? One large view that joins >=10 tables, or a few smaller views that join only the tables needed for individual pages?

Hello.
Newbie here. I've only been using SQL for about a year now and have some minor questions about sql objects that reference other objects.
We have some views which reference other views in the joins. I will call one the primary view and the one being referenced in the joins as the secondary view.
Recently we made changes to the secondary view.
After which the primary views which referenced it would not work because of this change and had to be 'refreshed' by using drop/create scripts which essentially just dropped it and recreated the exact same view. I do not recall the exact error message that was returned other than it seemed to suggest that it could no longer see the secondary view since it had been changed. Nothing in the primary view was changed in any way, just the secondary.
Some here where I work have suggested off hand that this was a recompile of the primary view because the contents of the secondary changed.
My questions are:
1. Exactly why did this happen and is there a proper name for it when it does?
2. The same problem does not seem to occur when we have stored procedures referencing views in the joins which had just been changed. Why is that?
Thanks for any help on the matter. I greatly appreciate it.

Hello,
to make a report easier I'm developing it using a view of joined views of joined views.
Is there any significant performance penalty as opposed to just having one big select?

Hi,
I've been using stored procedures to do queries including inner joins etc. I have always known about views but don't understand why they are used, what is there purpose, they seem the same as sql queries, is that true?
Is it more effiicient to use views rather than stored procedures to do your queries?
Really I just want to know why I would ever want to use views instead of stored procedures to do my queries?
Thanks in advance.

Need a Clarification in SQL Server 2000.
I would like to know if its possible to create a view of a table residing in a SQL server which is not the one in which we r currently working in
Desc:
1) Say i have 2 SQL servers( different Boxes) A & B
I am working in ' B ', can i have a view of a table residing in SQL server 'A' in my system( Server 'B')
2) Leaving out the network uncertainities, will such a setup give any performance issue when the view is for a table that captures daily transactions running into several
thousands of records
3) Is ther any other Alternative to access tables in another SQL sever without going for Views?
Plz find out and reply ASAP.

Hi there,First thing off, I'd like to know what Views are useful for? I thing it can speeds select query containing multiple join, but I'm not even sure if that's true.Second, assuming that Views speeds thing up for SELECT query, can it be used by NHibernate when restoring object from their persistence store (in this case, SQL 2k5) ? If not, can they be (views) of any use if we use NHibernate?Third, would it be better to create our crystal report using Views to improve performance?Thanks for anyone who participates in this thread! :-)

Hi There,
Is it possible to make views which takes Data from Multiple Servers?
NOTE: The view is very complex because it uses FOUR Diff. statements
joined together with UNION clause.
One more Q.
If my Query Analizer Displays following on execution of query.
" Internal Query Processor Error: The query processor could not produce a query plan."
What should be my approach to rectify the problem.
Any help would really be appreciated.

Be careful when implementing views (from SQL Server 97/2K). SQL Serverstores the metadata on the view at creation (or the last time it wassaved). This means if you have:SELECT * FROM table1it will put all the fields of table1 in the view's metadata. If youthen change table1 and add (for example) another field, this fieldwill not be visible in the view until you open it in design view andclick save (to update it).

hi all,
i had a view in my project, i am inserting a record in to that view(View contains a identity key for a column), with in stored procedure i am inserting a record i am not passing the identity key value to the insert statement. The record is getting inserted,Based on the identity key(i am getting the identity key value with Scope_Identity()) and with that value i am inserting records into another two tables.In this scenario every thing is working fine.
but now i am trying to place a trigger(instead of insert trigger) on the view, when i placed,it is not inserting record into first table,so i am not able to get the identity value of that record and process failed.
how can this achived, let me know.

Hi,
I have two servers that i want to create a SQL RS report on.
On one server there is an HR database with our staff details, on the other server there is a database of assets.
In order to report on the assets assigned to each user i am thinking that i will have to :
1) link the servers
2) create a view in the HR database exposing the fields needed
3) create a view in the assets database exposing the assets information joined to the view from the other server
4) create my reports on the view on the assets server.
is this right or am i barking up the wrong tree?

Please help.
I created a linked server with Oracle Provider for OLE DB to Oracle Database from SQL Server 2000 SP 4. Afterwards I created Views from this linked server and granted SQL Server users "select" access to the Views.
Unfortunately when they try to access the views the following error message was generated (see the attached image - error.gif).
Can someone please explain to me what is wrong?

Thanks in advance in reading this post ! I'm facing a situation in sql server 2000 sp4 with partitioned views.
I have a partition views that joins about 10 tables, in each table there is a check constraint.
For example, if a exec a select count(*) from VIEW where col1 = '20080101' , it goes for the table that has data for '20080101' .
If I exec a select col1,col2,col3,col4 from VIEW where col1='20080101', it goes to all tables and make an index seek.
I want the beaviour of query 1, beause it is just looking on 1 table and not one the 10.
Thanks in advance !

Do not trust values returned by materialized views under SQL Serverwithout frequently checking underlying tables!!!I already posted this message under microsoft.public.sqlserver.serverand I'm amazed nobody from Microsoft answered about this problem. Byinserting lots of data into our two main tables for about 30 minutes,we can fail our materialized view that performs a count_big on thosetwo tables.Executing (after of course having stopped inserting rows in our twotables)[color=blue]> SELECT SUM(field1+field2+field3) FROM MatView option(expand views)[/color]DOES NOT RETURN the same value than:[color=blue]> SELECT SUM(field1+field2+field3) FROM MatView with (noexpand)[/color]The second call - using the materialized view - returns a smallernumber (as if counts were lost during our bulk insert)As our data has to be accurate, we cannot use Materialized viewsanymore. This problem does not occur when the amount of data insertedis smaller. Rebuilding the clustered index on the view fixes theproblem; do we have to constantly be rebuilding the index to keep theview synchronize !?!!?!Is there a way to tell that our view is not synchronized? Justcomparing values returned by our view does not work for us as data isconstantly been inserted.System: SQL server 2000 SP3 Enterprise EditionVincent LIDOU

Hi,
I read that views can't be published with SQL Server 2005 replication. Is this planned for the future? If not what alternatives are there for this?
Simple collecting the data needed in a new table ain't a solution for us (memory consuming). And joining the data on the PPC ain't a good solution either (memory and time consuming). We only want to pull the data.

SQL 2005 SP2 in Managemrnt Studio...
I have a linked server set-up pointing to an instance that has several databases. In one catalog I have no tables or views being listed for the catalog. So I select a view, add the permissions that should allow the view to show in the list but it does not. And I did refresh and I did even restart management studio.
BTW: I can exec the view using a 4 part name.
Any one have an idea why the view don't show in the list?
Thanks much

This oracle db is managed by a third party , I have been given 10 views from oracle so I can extarct information I need. How should I design my SSIS package? Do I have to have 10 different data flows or there is an eaier way to run my 10 select statements from these views?
Is there any article that can give me some ideas on how to design SSIS packages to extract information from oracle?

Cordial greetings,
Again i need help with a couple of issues in migrating from Oracle to SQL Server 2005. I need the equivalent sentence in SQL Server of the following sentence:
CREATE OR REPLACE VIEW IBA_MPDATOSGENERALES AS (
SELECT IBA_MPPROCEDXLOC.IDPROCEDENCIALOCALIZACION, IBA_MPREQUERIMIENTOS.APLAZADOREQ, IBA_MPACCIONESXREQ.FECHAFINALAXR, IBA_USUARIOS.NOMBREUSU

AND IBA_MPACCIONESXREQ.USERNAME = IBA_USUARIOS.USERNAME
AND IBA_MPACCIONESXREQ.TIPOACCIONAXR = 'S'
AND IBA_MPACCIONESXREQ.CERRADAAXR = 'N'
AND NOT IBA_MPACCIONESXREQ.FECHAFINALAXR IS NULL
UNION

AND IBA_MPACCIONESXREQ.USERNAME = IBA_USUARIOS.USERNAME
AND (IBA_MPACCIONESXREQ.CERRADAAXR = 'S'
OR (IBA_MPACCIONESXREQ.CERRADAAXR = 'N' AND ((IBA_MPACCIONESXREQ.TIPOACCIONAXR = 'N' AND IBA_MPACCIONESXREQ.FECHAPROXEJECUCIONAXR IS NULL) OR (IBA_MPACCIONESXREQ.TIPOACCIONAXR = 'S' AND IBA_MPACCIONESXREQ.FECHAFINALAXR IS NULL))))
)
I know that (+) is for outer joins (left or right). I also know that UNION may mean FULL OUTER JOIN. but this query? The real query is a lot more complex, well actually there are just more fields needed from more tables but with this exmple is enough. The bottom line is that i need data from various tables, most of them involved in a JOIN clause. Also check out that in SQL Server doesnt exists the REPLACE word or does it?
Thank you in advance,

I wonder if anyone can help me -
I am trying to write a little application which recompiles any views dependent on a given view.
I have a script which will identify any views containing a given text string, but I now need a way to force SQL Server to refresh its cache info (or recompile) the views.
I have to admit that I am unclear on exactly how the caching works; i have tried using sp_recompile, but this does not seem to do the job.
Does anyone have any ideas?
