Hi guys,
I've been asked to re-write a sql view. The view itself contains
several calls to other views (embedded). Is there a way to get around
using embedded views. I've written the same query up using temp.
tables but obviously temp. tables can't be used in views?
Is there any special things I should be looking for?

I created a view V1 that uses an outer join with a table and calls a sub-view VS1 (ds_proj_report_date) which uses an inner join) and does an inner join with VS1. I also created another view V2 that uses inner join but does not call the sub-view VS1.
When I run the two views as below it works fine
Select * from V1
Union
Select * from V2
I then created another view V3 of the above union as
Create view V3
As
Select * from V1
Union
Select * from V2
Now when I run select * from V3, I get the following error.
Joined tables cannot be specified in a query containing outer join operators. View or function 'ds_proj_report_date' contains joined tables
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.
View 15 Replies View RelatedThis one's kind of hard to explain, so I've opted to post a simplifiedversion of our view that prompted me to ask this question: Thequestion is re-asked after the view...create view MainView (PrimaryKeyID,SubTotal1,SubTotal2,GrandTotal)asselect t.PrimaryKeyID,sum(t1.Total),sum(t2.Total),sum(t1.Total) + sum(t2.Total)from SomeTable tjoin CalculationTable t1 on ...join AnotherCalculationTable t2 on ...Notice in the 3rd column called "GrandTotal" how it calls the function"sum" two more times. Common sense tells me that this is notnecessary. in our case it's orders of magnitude worse... Is the queryoptimizer smart enough to only call these sums once per row in"SomeTable"? Common sense tells me that if we were to break the viewsapart into two views it would avoid this ineffeciency:create view InnerView (PrimaryKeyID,SubTotal1,SubTotal2)asselect t.PrimaryKeyID,sum(t1.Total),sum(t2.Total)from SomeTable tjoin CalculationTable t1 on ...join AnotherCalculationTable t2 on ...create view OuterView (PrimaryKeyID,SubTotal1,SutTotal2,GrandTotal)asselect iv.PrimaryKeyID,iv.Total1,iv.Total2,iv.Total1 + iv.Total2from InnerViewNotice how it appears that we've tricked the optimizer into thinkingthere are less operations. So my question is how does views handlethis situation? Does the optimizer treat both version the same? Or isone faster than the other? Or is there another, faster way? Doesadding levels of views slow down things, or are views simply likemacros and get removed when compiled (I think I've read the latter istrue actually)Thanks,Dave
View 1 Replies View RelatedHi,
doing my first steps in SSIS I wanted to copy data from 2 different SQL 2000 database servers to a SQL 2005 Data warehouse. For not having to deploy additional views and procedures to the individual systems I chose to create a Data Source View to create an abstract view on the different data sources. I found out that I can have named queries pointing to the two different data sources in the same view.
1 Project, 2 Data Sources, 1 Data Source View with 3 Named Queries
When I now add a Data Flow Task to the Control Flow how can I specify my DSV as Source for Transformations? I even added both OLEDB Connections to the Connection Manager but the Named Queries from my DSV do not appear at all. I even tried "SELECT from [myNamedQueryFromDSV]" but without success.
The description available at http://msdn2.microsoft.com/en-us/ms403395.aspx is bullshit. There is nothing to expand about the "Connection Manager" in the Data Flow Window. I can add a OLEDB Source as described in the above HOWTO and double click it. But the dropdown field for Connection Manager does offer only the two OLEDB Connections and nothing more. Among the items of the access mode "Tables and Views" the named queries not appear. It does not even work with a homogeneous Data Source View.
How can I make it work? Ain't there a better (working) HOWTO out there on how to enable DSV als Data Flow Task data sources? Do I have to wait for SP2 to solve the problem or is it not possible by intention?

Frank

What specific permissions do you need to be able to view information_schema views? I thought public role had permissions to select on these views, but this is not the case? What do I do?
my developers have db_reader, db_writer, and db_ddladmin. They do not have db_owner. If I make them Sysadmin in sql they can view them, but that doens't fit in our security setup we have. THoughts?
Thanks,
OK,
I have two data tables where depending on the time line item it is, it needs a different join.
So, it's like this:
Table Credit Card
Table Memo
If Credit Card is VISA, join on column A
If Credit Card is MA, join on column B
So, I created two views. One view has all the info joined on column A. The other view has all the info joined on column B.
How do I create a third view that will output all the data from View A and View B without making it into a cartesian product?
I can't change the table structure due to legacy application/data issues.
Thanks!
Everytime i try to insert into my database it rounds all my decimals to ints. In design view they are decimals. Here is the code:cmd.Parameters.Add("@B_NetProceeds", SqlDbType.Decimal).Value = B_Proceeds;In Database i get 859Label1.Text = B_Proceeds.ToString() gives me 858.67 Why does it keep rounding? Also my float works fine. Its just the decimal.
View 7 Replies View Relatedguys, 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

I have 2 views which contain the following fields:
EVENT,
WEEK,
SUBSCRIPTION,
QTY,
GROSS_AMOUNT,

The 2 views differ by SEASON. I'm attempting to combine the 2 views in to a single view or table grouping by EVENT, WEEK and SUBSCRIPTION:
EVENT,
WEEK,
SUBSCRIPTION,
Q6 (qty of season 1),
A6 (gross_amount of season 1),
Q7 (qty of season 2),
A7 (gross_amount of season 2)
Below is my select command:
------
SELECT TOP 100 PERCENT
dbo.vw_SEASON06.EVENT,
SUM(dbo.vw_SEASON06.QTY) AS Q6, SUM(dbo.vw_SEASON06.GROSS_AMOUNT) AS A6,
SUM(dbo.vw_SEASON07.QTY) AS Q7, SUM(dbo.vw_SEASON07.GROSS_AMOUNT) AS A7,
dbo.vw_SEASON06.WEEK,
dbo.vw_SEASON06.SUBSCRIPTION

dbo.vw_SEASON06.EVENT = dbo.vw_SEASON07.EVENT
GROUP BY
dbo.vw_SEASON06.EVENT,
dbo.vw_SEASON06.WEEK,
dbo.vw_SEASON06.SUBSCRIPTION
ORDER BY
dbo.vw_SEASON06.EVENT
-----
This creates the view but there are some issues. If an 'EVENT' exists in dbo.vw_SEASON07.EVENT and doesn't exist in dbo.vw_SEASON06.EVENT the value of the field 'EVENT' is set to NULL because the 'EVENT' name is returned from dbo.vw_SEASON06.EVENT. The same issue exists for 'SUBSCRIPTIONS' and 'WEEK'.
How can I create a single view/table that will include all the data from these 2 views without the NULL values in EVENT or SUBSCRIPTION?
Any help is appreciated!

This is my first post, so if i have not posted things in the best manner please lemme know how to be more informative,clear, so that i can learn.
So i have made a view with the following command

,b.AppraisalID_C
FROM dbo.Appraisal_C AS a
INNER JOIN dbo.AppraisalLineItem_C AS b ON a.AppraisalID_C = b.AppraisalID_C
---------------------------------------------------------------------------------------
the program im working on creates the SQL call to read from this view and creates
the following query
SELECT A.[AppraisalDate_C], A.[AppraisalID_C], A.[AppraisalLineItemID_C], A.[Customer_C], A.[Employee_C], A.[Notes_C], A.[TypeID_C], A.[Value_C]
FROM AppraisalView_C A
WHERE [AppraisalView_C].[AppraisalID_C] = 'APP-000006'
but I end up getting the dreaded "Msg 4104, Level 16, State 1, Line 1 The multi-part identifier "AppraisalView_C.AppraisalID_C" could not be bound." error....
I cant change the Query that is called, but i can change the view, what is wrong?
I am using BCP utility to export data from a view to text file. I get the following error

Hallo
I got a Link Server (IBMDASQL) and a view. And I am wondering how a view works.
If I try:
select * from [myView] where [myView].A = @A
Dos the Link Server retrieve the complete table and the SQL server applies the where condition?
Or
Does the Link Server use the where condition and retrieve just the requested records?
Hi!
There is a view in our replicated SQL-2000 database, that returns all user tables and views with replication state (0 if not included into publication, 1 if included):
Code Snippet
CREATE VIEW [dbo].[ViewREPL_PublishedObjects]
AS
SELECT TOP 100 PERCENT
CASE [xtype]
WHEN 'U' THEN 'Table'
WHEN 'V' THEN 'View'
ELSE NULL END AS [Object Type],
[name] AS [Object Name],
CASE WHEN [replinfo] = 0
THEN 0 ELSE 1
END AS [Replicated]
FROM [sysobjects]
WHERE
[xtype] in ('U', 'V')
AND [status] > 0
ORDER BY
(CASE [xtype]
WHEN 'U' THEN 1
WHEN 'V' THEN 2
ELSE 10
END),
[name]
Now we need to upgrade our database to SQL-2005, but [sysobjects] table have been changed, so neither Replicated state could be determined according on [replinfo] column value, nor User/System object according on [status].
So, I need a view with same functionality, that will work under SQL-2005 and 2008.
Please, help!

Hi
I have been asked to move our entire system over from SQL2000 to SQL2005, i eventually got our database and Cubes over to 2005 and converted all my reports to 2005 and deployed them successfully on RS2005
All the subscriptions have been made and they seem to work when i click to view them. Although when i create a DDS for all my reports to run then they fail. Now i've got over 5000 reports to build and i'm definately not going to create each report manually. My SQL Reports huild successfully, it just seems to be the MDX Reports with a problem, i;ve checked my stored procs and they seem fine, i've even seen the [Clients].&[All.Clients] difference from SQL2005 ---->&<------ that is not in SQL2000.
If someone has, or has had the same problem before would you please help me. Any advice or suggestions would be more than welcome.

Consider following code:
SELECT e1.EntityIdentity as CompanyID
FROM dbo.Entitye1 --company
JOIN dbo.EntityAssociationea
ON e1.EntityID = ea.EntityID1
JOIN dbo.Entitye2 --user
ON ea.EntityID2 = e2.EntityID
This query occurs as a sub-query in many stored procedures where exists a WHERE clause that includes CompanyID IN (above query).
Since dbo.Entity and dbo.EntityAssociation change infrequently I thought that an indexed view would really improve performance. But I've found one of the seemingly undocumented Microsoft features when trying to create the clustered index and get the following error msg:
Msg 1947, Level 16, State 1, Line 1
Cannot create index on view "ROICore.dbo.vEntityEntityAssociation_CompanyUser". The view contains a self join on "ROICore.dbo.Entity".
I really need to improve performance on this subquery. Entity currently has over 20m rows and EntityAssociation over 35m rows and both are growing.
How to improve performance? Indexes on both tables for the most part give index seeks, but I thought my saviour might be the index view. Obviously this will not work.
Good morning all,
I have searched everywhere for this and I can't find any information on it. When I use the Query Builder, in the top pane, the Filter pane, there are five columnsimension, Hierarchy, Operator, Filter Expession and Parameters.
In the dropdown for Operator, one of the choices is MDX. I cannot find any documentation on how to use this operator. I want to limit my filter to SELF_AND_AFTER, and I am hoping that this is possible using this operator. I know how to hand code it, but I have a ton of other tweaks to make to the query, so I want to use the Query Designer as much as I can.
Does anyone have any links to documentation on how to use this operator?
Thanks,
Kathryn
Hi,
It appears to work fine on my end however on my clients end, whenever they try to print a report that displays perfectly within the report viewer to their printer by selecting the printer button in the report it never ends up printing.., however if they go into printer setup and change the page range to print from all pages to just maybe one page and then select the print button it seems to print fine..
The printer seems to receive the information as the light flashes but no page kick out when all pages is selected to print..
Any help would be greatly appreciated..

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?
Cheers.
Why is using an embedded SELECT statement faster than using an embedded UDF that has the same exact SQL code within?
Example (not syntax corrected)
Ex1:
SELECT myValue1, myValue2 FROM myTable WHERE aValue = (SELECT Value FROM someTable WHERE myIndex = 800)
is much faster than something like
Ex2:
SELECT myValue1, myValue2 FROM myTable WHERE aValue = (dbo.FN_myUDF(@vmyIndex))
Given that dbo.FN_myUDF has the same code as the embedded select in the first example.
TIA,

I'm looking into a problem a friend is having, and I'll say right offthe bat that I work with with php and MySQL, and not MS SQL.What he is attempting to do (in MS SQL) is take two database fieldsfrom a table (string fields), multiply them together, and put them intoa third field. This third column in the table has not yet been createdthe time of running the query.If it needs to be multiple queries, that is fine. My first thought isto use a simple ALTER query to add the column to the table, then tocall a UPDATE function which uses a select statement inside of it. I'mnot sure if something like this can even be done.// ------------ Suggested queryUPDATE chrisslu SET 'discquantity' = '(SELECTchrisslu.quantity*chrisslu.nr_of_discFROM chrissluWHERE (str(period,6)>=? AND str(period,6)<=?))' WHERE(str(period,6)>=?Andstr(period,6)<=?)// ------------ End Suggested queryIt starts with an UPDATE, but replaces the value to be set with aSELECT statement. I honestly don't even think this query issyntactically correct, I'm just trying to get the general concept down:).So, question the first: Is this type of query possible? The reasonI'm doing this is because I was told MS SQL has no way of storingtemporary variables... otherwise I would just call a SELECT statement,store the variable, and UPDATE the new field from the variable afterthe ALTER statement.Second question: If it is possible, am I on the right track, or doesit need to be entered in completely different than what I have?Third: Regarding the 'type'. Do I need to do any kind of typecastingor conversion of the fields? Both chrisslu.quantity andchrisslu.nr_of_disc are string fields (that is what I was told, theymay be varchar of some kind). In order to use them in a mathstatement, do they have to be floats, or doubles, or something similar?I appreciate any response, I know this was a long winded question.Chris
