How Do I Refresh A View?
Jun 25, 2007You know how I mentioned before that I was working with a database with a (bunch of) view(s) that are defined like this...
CREATE VIEW MyView AS
SELECT * FROM ExampleTable
Well, after altering the underlying table I noticed that the view is not picking up the new columns which leads me to believe I need to refresh the view.
Is this possible, if so, how?

T-SQL (SS2K8) :: Hierarchical Update Dataset - Refresh Datatable After Delete
Feb 5, 2015Imagine the following scenario: two tables (say, "requests" and "details") are joined in a 1:n relationship on MSSQL 2008. Both tables contain an ID (autoincrement field) and a timestamp field for proper concurrency management. Data access in the frontend is provided by a typed dataset in VS 2010. There are SPs on the server which select, update, insert or delete data in each of the two tables (so, 8 SPs alltogether: uspRequestsSelect, uspDetailsInsert etc.). These SPs are used for data access in the dataset. The GUI is a Windows form with 2 datagridviews, one for request datatable and one for the child-relation-based datatable FK_request_details. So, each request shows its details. The form works well so far.
Now, trouble strikes. A business rule says: "the first details row of a request (=row with lowest ID) always has a 0 in column "additional fee". For additional detail rows, this field has to be set to constant value 45". In short: the first detail row of each request is free, second and later details are charged 45 €.
So, I created a SP "uspRequestFeeManager", which recalculates all (!) detail rows of a request. This SP is called in uspDetailsInsert, uspDetailsUpdate and uspDetailsDelete, as each of this cases causes the additional fee to be recalculated for all rows (as rowcount can change). In Management Studio, this works as well!
But: as the uspRequestFeeManager changes data even for rows the user did NOT touch, there's a concurrency exception in my frontend in the following case:
In a request with 2 detail rows (first row has fee = 0, second = 45), the user deletes the row with fee = 0. Committing via TableAdapterManager calls uspDetailsDelete, which calls uspRequestFeeManager, which sets the remaining single details row to a fee value of 0 (which is correct!). This causes TableAdapterManager.UpdateAll to fail ("concurrency exception; delete command has handled 0 of 1 expected records"), as uspRequestFeeManager has "edited" a row which the user didn't touch, and thus updated its timestamp as well. So, the list is out of sync.
The uspRequestFeeManager looked like a good idea... but it seems not to be.
Approach would be: instead of calling the uspRequestFeeManager from within the SP, call it programmatically after TableAfterManager.UpdateAll, and after that, 're-fill' the details datatable with the updated data. But that would transfer business logic from server to client. I don't like that...
Does A View Refresh Itself When I Reference It? (was Question On Views)
Feb 24, 2006guys, ive never worked with Views before so forgive me.
i know how to create one, and that it creates a virtual table in memory, but i've got one small question.
if i create a view:
CREATE view dbo.myView
as
select Distinct FirstName,LastName from SomeTable
When ever i reference that view, such as
Select FirstName,LastName
from myView
where LastName like 'Jo%'
does that View Refresh itself??
in other words does it run each time i Reference it??? or is it static from when i created it.
Wouldnt it be easier just to use a #TempTable or some other Table thats used to hold a few values?
thanks for any help

T-SQL (SS2K8) :: Pulling Errors From A Linked Server?
Jan 28, 2013I've got a linked server to an attomix database. When i send an erroneous statements to the server an error message is returned to the Message pane is SSMS as below:-
OLE DB provider "MSDASQL" for linked server "noble" returned message "[Noble Systems Corp.][ATOMIX ODBC Driver]Atomix error - (-217)Column (crap) not found in any table in the query.
".Msg 7215, Level 17, State 1, Line 5, Could not execute statement on remote server 'noble'.
I'm trying to store this error using the ERROR_MESSAGE() function but i only get the second statement ('Could not execute statement on remote server 'noble'.') rather than the real error in the first line. The first line statement is displayed in black as a message rather than red for an error.
how i can access the first error?
T-SQL (SS2K8) :: CTE With Linked Server - Multipart Identifier Could Not Be Bound

This ran fine for almost 20 hours and then dies with a multipart identifier could not be bound error (exact error below CTE).

T-SQL (SS2K8) :: Errors When Inserting Rows From A Linked Server
Aug 14, 2015I have a script that inserts rows from a linked server. It basically looks like this:
use mydb;
go
insert into my.table (col1, col2, ...)
select col1, col2, ...
from LinkedServer.db.my.table;
The DDL for both tables is identical: 550 columns (de-normalized from a data warehouse), of which 548 are varchar(max). The remaining two are varchar(255). (not my design! but unchangeable at the moment).
Running my query raises an error:
Cannot create a row of size 9948 which is greater than the allowable maximum row size of 8060.
The statement has been terminated.
Now, inserting rows on the table on the LinkedServer has never been an issue. (Since most columns are varchar(max), SQL has the option to store the data off-row.) The data is there, intact and whole. However, when pulling it into my target server using a LinkedServer (4-part naming), I get the error.
Three pairs of eyes have confirmed that the table definitions are identical on both source and target.

View 1 Replies View RelatedHow Does A View And SP Over A Linked Server Worked...
Feb 7, 2008
I am working with Two Server €˜X€™ and €˜Z€™
In €˜X€™ server, I have a linked server named €˜CustSrv€™ which is connecting to €˜Z€™ server
In the €˜Z€™ server I have a Database named €˜SalesDB€™
I have a view name vw_CusgtomerData in my €˜X€™ server which is selecting data from SALESDB..Customer_Tbl from the €˜Z€™ server through that linked server (€˜CustSrv€™)
The View is simple selecting data from Customer_Tbl from SalesDB
SELECT * FROM CustSrv.SalesDB.dbo.CUSTOMER_Tbl
[Note here using * for all columns?? Is it ok for performance aspects]
Now I have some Application which are using that view through some stored procedure.Few of them passing some parameters like Cust_Id etc
Now my query is that.. Am I fulfilling all performance issues?
Or
What is the suggestive way to fetch data from that remote (Linked Server) server to get good performance benefit?
In my opinion we can fetch data 4 different way from that linked server€¦
A.SELECT * FROM CustSrv.SalesDB.dbo.CUSTOMER_Tbl
B.exec GetCustomerData 65
[Sp_GetCustomerData is a Storedprocedure which is passing a parameter 65 that is Customer_ID and the procedure is selecting data from the view vw_CusgtomerData]
C.SELECT cu_customer_id, cu_customer_name FROM vw_CusgtomerData ORDER BY cu_customer_name
Or
SELECT * FROM vw_CusgtomerData where Customer_ID=65
D.select * FROM OPENQUERY
(CustSrv,'SELECT Customer_ID,cu_customer_name FROM SalesDB.dbo. CUSTOMER_Tbl ORDER BY cu_customer_name ')
Am I bypass the concept of view and fetch data directly in the stored procedure through the linked server ??
T-SQL (SS2K8) :: Extracting Large Tables From Offsite Linked Server
Oct 1, 2014I work in Healthcare IS for Company A, but Company B is hosting one of our EMR programs for us. This was done on purpose, so that whether a patient is seen at one or the other, their medical history is more complete. However, this puts all of the data that I need to get to on a server across town that I can only access via Sql Server Management Studio as a linked server.
Now, in some ways, the performance has been better than I expected, but sometimes it behaves very erratically. I am using OPENQUERY to handle all of the pulls, and am not joining to any local tables, in order to maximize efficiency.
Here is some of the code I run, and what happens:
SELECT *
FROM
OPENQUERY([linkedservername],
'
SELECT *
FROM Encounter_ItemChild
[Code] ....
***The above query was programmatically generated by taking the IDs from the second query, and packing as many into the IN condition as possible. Each statement could hold only about 900 IDs, so around 70 queries get built...however, each one returns the records in question in 1-2 seconds.
My main question is...if the second query pulls all IDs from Encounter in a few seconds, and that query is used in the first query's WHERE clause, why does it spin and spin, while manually throwing the IDs in instead runs almost instantly?
How To Refresh A Data Source View And Autogenerate/Re-Deploy The Corresponding Report Model
Jan 9, 2007Hi everyone!,
Our team is new to SSRS and we are trying to figure out how to refresh the data source view, autogenerate the corressponding report model and Re-Deploy the Report Model (rewrite existing Report Model) on the server on a periodoc basis or trigger the whole action whenever there is a change in the database on some specific tables.
We prefer to do this action through a Agent job ( a diff approach is also welcome).
Are there any stored procs out there?

SQL Server 2008 :: View Creation Using XML Column On Linked / Distributed Server?
Sep 4, 2015A recent SharePoint upgrade has rendered several views obsolete. I am redefining them so that our upper level executive reports show valid data.(yes, I know that doing anything to sharepoint could cause MS to deny support, having said that, this is something I've inherited and need to fix, pronto) The old view was created like so:
USE [AHMC]
GO
/****** Object: View [dbo].[vwSurgicalVolumes] Script Date: 09/04/2015 09:28:03 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE VIEW [dbo].[vwSurgicalVolumes] AS
SELECT
[code]....
As I said, this view is used in a report showing surgical minutes.SharePoint is now on a new server, which is linked differently (distributed?) I've used OPENQUERY to get my 'new' query to work;
SELECT *
FROM OPENQUERY ([PORTALWEBDB], 'SELECT
--AllLists
AL.tp_ID AS ALtpID
,AL.tp_WebID as altpwebid
,AL.tp_Title AS ALTitle
[code]....
My data (ie surgical minutes, etc) seems to be in the XML column, AUD.tp_ColumnSet . So I need to parse it out and convert it to INT to maintain consistency with the previous view. How do I do this within the context of the view definition?Here is a representation of the new and old view data copied to excel :
<datetime1>2014-08-14T04:00:00</datetime1><float1>2.000000000000000e+000</float1><float2>4.190000000000000e+002</float2><float3>1.600000000000000e+001</float3><float4>8.110000000000000e+002</float4><sql_variant1 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:sqltypes="http://schemas.microsoft.com/sqlserver/2004/sqltypes"
[Code] ....
can't format it to make it look decent. InHouseCases =2, InHouseMinutes=419, OutPatientCases =16, OutPatientMinutes=1230. This corresponds to the new data I can see in the XML column; 2.000000000000000e+000 is indeed 2 and 4.190000000000000e_002 is indeed 419.

Slow MDB Linked View
Jul 23, 2005I previously posted re. this, but thought I'd try again with a summary offacts.I have an Access 2000 MDB with a SQL Server 7 back end. There is a view thatis linked to the database via ODBC and has been in place for several yearswithout any performance problems.Recently I added a couple of fields to the output of the view, and it becamevery slow when scrolling. When just opened in the database window, thelinked view takes about a second to scroll down one screen. When opened inthe form (in Continuous Form view), it takes about 2-3 seconds. It used toscroll just about instantaneously.I tried removing the few fields I added to restore the view to its previousform, but it had no effect. The view was still much slower than it had been.The total number of records returned from the view is about 1300, so it'snot a large number of records. The view has about 25 fields.I found that when I link the view in the MDB without specifying a uniqueindex, it scrolls very quickly -- almost instantaneously. But when I specifythe unique index, it is slow. Since the view needs to be edited, it needsthe unique index defined.As noted, it's been in place for years, with a unique index defined, yetwithout the slowness. Any ideas as to what might have caused this and whatmight be done would be appreciated.

I have a main tablewith 50,000 records; and I have a selections table with 50,000 records foreach machine that uses the database (about 25-50). This allows each user tohave their own set of selections.The selections table has three fields: ID (int), Sel (bit), MachName(varchar). ID and MachName comprise the primary key.I have a view that combines the main table and the entries for theselections table for the current machine (SQL below). The view works finewhen opened in EM and QA. And if I create a pass-through query from myAccess MDB file, the results are displayed fine.However, if I link the view to the Access MDB file, I get "#Deleted" inevery field of every record (which seems to indicate that the records werethere and then they were gone). However, if I hard-code the machine nameinto the same view instead of using HOST_NAME and then relink the view tothe MDB file, the linked view opens fine. Only when I use HOST_NAME as aparameter in the view is there a problem with it.Anyone have any idea what's going on here, or have heard of any issues withHOST_NAME and ODBC linked objects?

The higher thedialect level, the more operations SQL Server can delegate to theprovider.Note The SQL Server dialect level is used when the providercorresponds to a SQL Server linked server.Each dialect level is a superset of the lower levels. Therefore, if anoperation is delegated to a particular level, then Queries involvingthe following are never delegated to a provider and are always it isalso delegated to all higher levels.evaluated locally:•bit•uniqueidentifier================================================This suggests to me that any query having where criteria applied to adatatype uniqueidentifier will have the where criteria applied AFTERdata is returned from the linked server.Any ideas on the root problem, and a better solution to get the queryand all the where criteria applied on the remoted linked server?Thanks,Bernie

DB Engine :: How To Point Linked Server To Specific Database / Rename Linked Server
Apr 24, 2015I am using Linked Server in SQL Server 2008R2 connecting to a couple of Linked Servers.
I was able to connect Linked Servers, but I cannot point to a specific database in a Linked Server, also, I cannot rename Linked Server's name.
How to point the linked server to a specific database? How to rename the Linked Server?
The following is the code that I am using right now:
USE [master]
GO
EXEC master.dbo.sp_addlinkedserver
   @server = N'Machine123Instance456',
   @srvproduct=N'SQL Server' ;
GO
EXEC sp_addlinkedsrvlogin 'Machine123Instance456', 'false', NULL, 'username', 'password'Â Â
Scripting Stored Procedure Add With Linked Server Reference When Linked Server Is Not Available
Jul 18, 2006Is there a way to bypass the syntax checking when adding a stored procedure via a script?
I have a script that has a LINKed server reference (see below) .
INSERT
INTO ACTDMSLINKED.ACTDMS.DBO.COILS ..etc.
ACTDMSLINKED does not exist at the time I need to add the stored procedure that references it.
PLEASE to not tell me to add the LINK and then run the script. This is not an option in this scenerio.
Thanks,
