Is This What A View Is For?
Mar 31, 2006
I've never worked with views before though I have a vaugue idea what they're for :)
I have a table that is quite large and growing fast and my primary use for the data is to run lots of aggregate functions on it.
See my previous post for an example:
http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=63748
Queries like that are taking 10 seconds to run.
So what I'm looking for is a way to store the results of a query like that, run the actual query maybe once an hour, and any time a user needs that data they get the results of the last run.
My first thought was to just have "summary" tables that get updated by a Stored Procudure that runs on a schedule under "Jobs". Is there a better way?
Thanks!
Edit: Some of the "summary" data would be based on date, so the summarized data would only need to be processed once. Don't know if that is something to consider.

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
ON Vendors.VendorID = Invoices.VendorID
[code]...

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 compared view query plan with query plan if I run the same statementfrom view definition and get different results. View plan is moreexpensive and runs longer. View contains 4 inner joins, statisticsupdated for all tables. Any ideas?

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.

I have this view in SQL server:
CREATE VIEW dbo.vwFeat
AS
SELECT dbo.Lk_Feat.Descr, dbo.Lk_Feat.Price, dbo.Lk_Feat.Code, dbo.SubFeat.SubNmbr
FROM dbo.Lk_Feat INNER JOIN
dbo.SubFeat ON dbo.Lk_Feat.Idf = dbo.SubFeat.Idt
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.
Thanks for help

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

When I ran this SQL Query, I got an unexpected result.
//Sql Query
Code:
SELECT distinct Year FROM vw_EMD_Options_Pricing WHERE (Year >= '2003') AND (Year <= '2008')
The view is the "vw_EMD_Options_Pricing". The request I got is the year that go from 1981 to 2008. This is for MS-SQL 2000. Why does the SQL Query does that?

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

1030712008FLO
1030712008FPO
1030712008FSO
LO ,PO and SO are constant.
How should I do that?

I have tried Books online and have queried this forum for assistance in creating a SQL view and have spent much time trying to solve on my own.
I am working with only one table:
Sales: SOP10200
SOPTYPE ITEMNMBR ITEMDESC QUANTITY
3 Widget special 4
3 Widget special 7
2 Gadget special 1
2 Widget special 12
3 Gadget special 5
I want to create a view that summarizes the data based upon SOPTYPE and ITEMNMBR as follows:
ITEM_NUMBER ITEM_DESC QTY_INVOICED QTY_ORDERED
Widget special 11 12
Gadget special 5 1
I am struggling whether to use a select statement or a CASE statement.
I am able to summarize one SOPTYPE as follows:
CREATE VIEW [dbo].[Tec_SOP10200_INVOICE_Qty]
AS
SELECT ITEMNMBR as ITEM_NUMBER, ITEMDESC as ITEM_DESC, SUM(QUANTITY) AS QTY_INVOICED
FROM SOP10200
WHERE SOPTYPE = 3
GROUP BY ITEMNMBR, ITEMDESC
But I need more than one soptype in same view
I tried this CASE statement -
Create tec_sales_view
as
SELECT SOP10200.ITEMNMBR as ITEM_NUMBER
, SOP10200.ITEMDESC as ITEM_DESC
, SOP10200.QTY1 'QTY_INVOICED'
, SOP10200.QTY2 'QTY_ORDERED'
, (CASE
WHEN SOP10200.SOPTYPE = 3 THEN SUM(QUANTITY) QTY1 ELSE 0)
(CASE
WHEN SOP10200.SOPTYPE = 2 THEN SUM(QUANTITY) QTY2 ELSE 0)
END as QTY_Type
FROM SOP10200
GROUP BYITEMNMBR, ITEMDESC, QTY1, QTY2
But I get error message doesn't recognize QTY1 (invalid column name)
Thank you in advance for any assistance.......
