Using The Same View Repeatedly
Jul 23, 2005
Hi.
A question I have is with regard to the use of views with SQL2000. If
I have a view called "A_view" and used in the following manner;
----------------
SELECT ...
FROM A_View
WHERE ....
UNION
SELECT ....
FROM A_View
WHERE .....
-----------------
is the view computed twice? Ideally if the view is computationally
expensive I would rather it was only computed once.
Also this would be preferred for data consistency.
Is there a way to ensure the view is only computes once?
Regards JC.......

Hey all. right now I've been spinning my wheels for almost 2 days on a problem with c# 1.1/sqlserv 2005...
I have a dataset that's filled with data that I'm trying to write to a database, I've ensured that the dataset is fine.
I do a transaction to write the code to the table,
an insert command, and an update command.
then commit the transaction
Everything seems to work fine, but when I go look at the table, it doesn't actually write any rows!
The weird thing is deletion of the rows works fine on the same table.
I look at the sqlserver tracer and watch it do the deletion on the table, skip right over the insert statements (ie: no insert statements show up whatsoever in the tracer) then commit the transaction.
If anyone has ever heard of something like this happening i would really appreciate some advice. I'm trying to be as specific as I can about the problem, and I've been spinning my wheels for almost 2 days without avail.
I've tried making other tables and writing to them, getting the same results. I think it's somehow not referencing everything correctly but again, everything seems like it's fine.
Thanks

Hi all,
I've been handed a SQL Server that is used as an MIS source. There are 4 databases that carry out the task of importing data from various sources, then manipulting that data, and offering the data for reporting purposes.
The vendor has also created several other databases (of which there are also 4), but no-one in my company seems to know the purpose of these dbs.
In the logs, there are approximately 8/9 messages per second - not every second, but numberous seconds per minute - stating....
Starting up database 'db_name'.
... each time, all 4 of the mysterious dbs appear.
I've checked the spid that is running this job this morning, and it seems to be NT AUTHORITYSYSTEM connected to one of the original 4 report databases.
Does this have any affect on the performance of the server, or the specific db attached to the user?
Thanks in advance.

I have a table with 3 columns , let say (PatientID int, AppointmentDate date, PatientName varchar(30))
My source data looks in below way..
PatientID AppointmentDate PatientName
1 01/01/2012 Tom
2 01/10/2012 Sam
3 02/15/2012 John
I need output in below way..
PatientID AppointmentDate PatientName
1 01/01/2012 Tom (actual patient record)
null 01/10/2012 Tom
null 02/15/2012 Tom
null 01/01/2012 Sam
2 01/10/2012 Sam (actual patient record)
null 02/15/2012 Sam
null 01/01/2012 John
null 01/10/2012 John
3 02/15/2012 John (actual patient record)
I need t-sql to get above output. Basically the appointment dates are repeatedly assigned to each patient but only difference is patientid will be not null for actual patient record.
Create table sample (PatientID int null, AppointmentDate date null, PatientName varchar(30) null)
Insert sample values (1,'01/01/2012' ,'Tom'),
(2,'01/10/2012','Sam'),
(3,'02/15/2012','John')

Hi,
Here is my query which lists all orders for products supplied by Supplier-3.
A typical Query on the Northwind database i wrote is like this..
Select * FROM [Order Details] WHERE ProductID in
(Select ProductID From Products where SupplierID = 3)
The subquery in Red was used in multiple places in one of my Stored Procedures..
So what i thought was - use a temp table to store the resultset from this subquery, and then use the temp table instead of querying the Products table everywhere..
My Query looked something like this..
Declare @ProductIDs TABLE
(ProductID int)
INSERT INTO @ProductIDs
Select ProductID From Products where SupplierID = 3
Select * FROM [Order Details] WHERE ProductID in
(Select ProductID FROM @ProductIDs)
Well, I expected an increase in performance with the latter approach, but seems my Stored Procedure is taking more time with the second solution..
Would be glad to see ne explanation on this behavior..
Thanks in Advance..

I am using the SqlDependency to notify me of data changes in a table. However, as soon as I start it, the OnChange event fires over and over even though no data has changed.
Essentially All I want to do is be notified when records are inserted into a table. I am able to get another example to work using a Service Broker Queue and a sql query of WAITFOR ( RECEIVE CONVERT(int, message_body) AS msg FROM QueueMailReceiveQueue ) However I would prefer not to use a queue for once my messages have been read they are taken off the queue and I would rather control that manually.
Any help with getting SqlDependency to notify my app when records are added and not over and over when the data has changed would be great.
Here is my code:
Code Snippet
public partial class Form1 : Form {
public static event OnChangeEventHandler OnChange;
string _strConnString = "Data Source=localhost;Integrated Security=SSPI;Initial Catalog=email_queue;Pooling=False;";
string _strSql = "SELECT email_id from email where isprocessed = 0";
private DataSet dataToWatch = null;
private SqlConnection connection = null;
private SqlCommand command = null;
SqlDependency dependency = null;
SqlDataReader sdr = null;
public Form1() {
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e) {
SqlDependency.Stop(_strConnString);
SqlDependency.Start(_strConnString);
if (connection == null) {
connection = new SqlConnection(_strConnString);
connection.Open();
}
if (command == null) {
command = new SqlCommand(_strSql, connection);
}
if (dataToWatch == null) {
dataToWatch = new DataSet();
}
GetData();
}
private void GetData() {
dataToWatch.Clear();
command.Notification = null;
dependency = new SqlDependency(command);
dependency.OnChange += new OnChangeEventHandler(dependency_OnChange);
command.CommandTimeout = 400;
using (SqlDataAdapter adapter = new SqlDataAdapter(command)) {
adapter.Fill(dataToWatch, "email");
}
}
private void dependency_OnChange(object sender, SqlNotificationEventArgs e) {
ISynchronizeInvoke i = (ISynchronizeInvoke)this;
if (i.InvokeRequired) {
OnChangeEventHandler tempDelegate = new OnChangeEventHandler(dependency_OnChange);
object[] args = { sender, e };
i.BeginInvoke(tempDelegate, args);
return;
}
dependency = (SqlDependency)sender;
dependency.OnChange -= dependency_OnChange;
this.Text = DateTime.Now.ToString();
GetData();
}
private void Form1_FormClosed(object sender, FormClosedEventArgs e) {
SqlDependency.Stop(_strConnString);
if (connection != null) {
connection.Close();
}
}
}

SQL 2005 SP2 Failes repeatedly - SQLServer2005SP2-KB921896-x86-ENU
Failed install on several Win 2003 Ent Ed., 32bit servers both named and default instances, both upgrades and direct installed versions. Why would MS put out such a riddle?
Error Message is " A recently applied update, KB921892, failed to install.
Also, confoundingly, the error log for the hotfix indicates
""9.00.3042.00 while the update version is: 9.00.2047.00."
But the version display on the properties of one of the servers is:
"Microsoft SQL Server 2005 - 9.00.1399.06 (Intel X86) Oct 14 2005 00:33:37 Copyright (c) 1988-2005 Microsoft Corporation Enterprise Edition on Windows NT 5.2 (Build 3790: Service Pack 2) "
Any help or comments are deeply appreciated, as the seems to be impacting DB Maintenance Plans, etc...

I'm having many many issues installing sql server management tools. i had visual studio 2005 installed first, but uninstalled and sql related things before trying to install sql server management tools again - i also deleted the program files/microsoft sql server/ folder so there are no references.
Firstly the system configuration check gives me a warning that the system doesn't meet the recommended hardware requirements - this is wrong... i've got 2.33Ghz dual core + 1gb of ram...
I select just management tools + client connectivity to install and click next -> the setup support files/native client/owc11 etc all install fine but workstation components etc fail and the setup log appears to either be empty and not available
and MSXML6 fails... after clicking finish the installer appears to crash - : "Microsoft SQL Server 2005 Setup has encountered a problem and needs to close. We are sorry for the inconvenience"... I have tried all sorts of variations on this install and have had no problems in the past - please help!

I am looking to create a constraint on a table that allows multiplenulls but all non-nulls must be unique.I found the following scripthttp://www.windowsitpro.com/Files/0.../Listing_01.txtthat works fine, but the following lineCREATE UNIQUE CLUSTERED INDEX idx1 ON v_multinulls(a)appears to use indexed views. I have run this on a version of SQLStandard edition and this line works fine. I was of the understandingthat you could only create indexed views on SQL Enterprise Edition?

Write a CREATE VIEW statement that defines a view named Invoice Basic that returns three columns: VendorName, InvoiceNumber, and InvoiceTotal. Then, write a SELECT statement that returns all of the columns in the view, sorted by VendorName, where the first letter of the vendor name is N, O, or P.
This is what I have so far,
CREATE VIEW InvoiceBasic AS
SELECT VendorName, InvoiceNumber, InvoiceTotal
From Vendors JOIN Invoices

Hi guys 'n gals,
I created a query, which makes use of a temp table, and I need the results to be displayed in a View. Unfortunately, Views do not support temp tables, as far as I know, so I put my code in a stored procedure, with the hope I could call it from a View....
I tried:
CREATE VIEW [qryMyView]
AS
EXEC pr_MyProc
and unfortunately, it does not let this run.
Anybody able to help me out please?
Cheers!

I had given one of our developers create view permissions, but he wants to also modify views that are not owned by him, they are owned by dbo.
I ran a profiler trace and determined that when he tries to modify a view using query designer in SQLem or right clicks in SQLem on the view and goes to properties, it is performing a ALTER VIEW. It does the same for dbo in a trace (an ALTER View). He gets a call failed and a permission error that he doesn't have create view permissions, object is owned by dbo, using both methods.
If it is doing an alter view how can I set permissions for that and why does it give a create view error when its really doing an alter view? Very confusing.

When ever I open using SQL Entreprise manager to edit it by adding or removing a field i inserts Expr1,2.. and I don t want that. The result I get is:
SELECT dbo.Lk_Feat.Descr AS Expr1, dbo.Lk_Feat.Price AS Expr2, dbo.Lk_Feat.Code AS Expr3, dbo.SubFeat.SubNmbr AS Expr4
FROM dbo.Lk_Feat INNER JOIN
dbo.SubFeat ON dbo.Lk_Feat.Idf = dbo.SubFeat.Idt
I don t want Entreprise manager to generate the Expr fields since I use the real fields in my application.

I was looking through our vendors views, searching for something Ineeded for our Datawarehouse and I came across something I do notunderstand: I found a view that lists data when I use it in t-sql,however when I try to use the statement when I modified the view (viaMS SQL Server Management Studio) I can not execute the statement. I getThe column prefix 'dbo.tbl_5001_NumericAudit' does not match with atable name or alias name used in the query.Upon closer inspection, I found two ON for the inner join, which I dontthink is correct.So, how can the view work, but not the SQL that defines the view?SQL Server 2000, up to date patches:SELECT dbo.tbl_5001_NumericAudit.aEventID,dbo.tbl_5001_NumericAudit.nParentEventID,dbo.tbl_5001_NumericAudit.nUserID,dbo.tbl_5001_NumericAudit.nColumnID,dbo.tbl_5001_NumericAudit.nKeyID,dbo.tbl_5001_NumericAudit.dChangeTime,CAST(dbo.tbl_5001_NumericAudit.vToValue ASnVarchar(512)) AS vToValue, dbo.tbl_5001_NumericAudit.nChangeMode,dbo.tbl_5001_NumericAudit.tChildEventText, CASEWHEN nConstraintType = 3 THEN 5 ELSE tblColumnMain.nDataType END ASnDataType,dbo.tbl_5001_NumericAudit.nID,CAST(dbo.tbl_5001_NumericAudit.vFromValue AS nVarchar(512)) ASvFromValueFROM dbo.tbl_5001_NumericAudit WITH (NOLOCK) LEFT OUTER JOINdbo.tblColumnMain WITH (NoLock) INNER JOIN---- Posters comment: here is the double ON--dbo.tblCustomField WITH (NoLock) ONdbo.tblColumnMain.aColumnID = dbo.tbl_5001_NumericAudit.nColumnID ONdbo.tbl_5001_NumericAudit.nColumnID =dbo.tblCustomField.nColumnID LEFT OUTER JOINdbo.tblConstraint WITH (NOLOCK) ONdbo.tblCustomField.nConstraintID = dbo.tblConstraint.aConstraintID AND(dbo.tblConstraint.nConstraintType = 4 ORdbo.tblConstraint.nConstraintType = 9 ORdbo.tblConstraint.nConstraintType = 3)UNION ALLSELECT aEventID, nParentEventID, nUserID, nColumnID, nKeyID,dChangeTime, CAST(CAST(vToValue AS decimal(19, 6)) AS nVarchar(512)) ASvToValue,nChangeMode, tChildEventText, 5 AS nDataType,nID, CAST(CAST(vFromValue AS decimal(19, 6)) AS nVarchar(512)) ASvFromValueFROM dbo.tbl_5001_FloatAudit WITH (NOLOCK)UNION ALLSELECT aEventID, nParentEventID, nUserID, nColumnID, nKeyID,dChangeTime, CAST(vToValue AS nVarchar(512)) AS vToValue, nChangeMode,tChildEventText, 2 AS nDataType, nID,CAST(vFromValue AS nVarchar(512)) AS vFromValueFROM dbo.tbl_5001_StringAudit WITH (NOLOCK)UNION ALLSELECT aEventID, nParentEventID, nUserID, nColumnID, nKeyID,dChangeTime, CONVERT(nVarchar(512), vToValue, 121) AS vToValue,nChangeMode,tChildEventText, 3 AS nDataType, nID,CONVERT(nVarchar(512), vFromValue, 121) AS vFromValueFROM dbo.tbl_5001_DateAudit WITH (NOLOCK)

A colleague of mine has a view that returns approx 100000 rows in about 60 seconds.
He wants to use the data returned from that view in an OLE DB Source component.
When he selects the view from the drop-down list of available tables then SSIS seems to hang without any data being returned (he waited for about 15 mins).
He then changed the OLE DB Source component to use a SQL statement and the SQL statement was: SELECT * FROM <viewname>
In this instance all the data was returned in approx 60 seconds (as expected).
This makes no sense. One would think that selecting a view from the drop-down and doing a SELECT *... from that view would be exactly the same. Evidently that isn't the case.
Can anyone explain why?
Thanks

How do I set up a sql statement to use as a view?
I want to use two tables but they are both from different databases.
From the Offices database I want to use a table called Office Code and only the Name column
The other database is called Library and I want to use a table called Requestors and join it to others.
I've set the stored procedure up that I want to use to get most of the data besides the data in the offices database.
Create view GetDataview
select requestors.officeCode, requestors.Fname + ' ' + requestors.Lname as [Name], Titles.title as Title from requestors
join libraryrequest on libraryrequest.requestorid = requestors.requestoridjoin Titles on Titles.Titleid = libraryrequest.Titleidwhere officecode <> 0order by OfficecodeGO How do I add the database offices, table officecodes to this view to use the Name column?
I hope this makes sense

I have a database with a view to another table in another database which I created a form out of. I was wondering when if this rule applies
"Data Entry" property of the form is set to True. The default value for this property is "False" which means that Access opens the form and shows the existing records. However, if set to True, the Data Entry property of the form specifies that the form will only show a blank record.
The reason I am asking is because you cant see the records after you close the form and reopen it again.

Hi,
I have a view in my database which returns:
ID Date Area
1010712008F
1020712008F
1030712008F
I should change this view’s output in such a way that for each Id I should have 3 record:
IDDateAreaType
1010712008FLO
1010712008FPO
1010712008FSO
1020712008FLO
1020712008FPO
1020712008FSO
1030712008FLO
1030712008FPO
1030712008FSO
LO ,PO and SO are constant.
How should I do that?
Thanks.
