Been pulling my hair out with this one for some time now ... hope someone out there can help :)
I have a database view which is an aggregated view of a number of tables. Trouble is I need to create what would effectively be a primary key for the view.
Can anyone suggest a sound way of doing this other than moving to Oracle :)
I am wondering if there is such thing as primary key for a view? Assuming, that my view is based on a single table and it's just a subset of columns (some of them renamed) including PK of the table it's based on.
The reason for my question is this - we're using Reverse POCO generator which automatically generates C# Model class and Configuration file for our tables and views. For the view is lists all the columns as a key and therefore I obviously can not use normal way of updating that view. I posted that as an issue here [URL] .... but I am thinking there is no such thing as the "primary key" for a view.
The query used to generate the classes is extremely complex already but may be it can be modified to get the PK ?
SELECT [Extent1].[SchemaName],
[Extent1].[Name] AS TableName,
[Extent1].[TABLE_TYPE] AS TableType,
[UnionAll1].[Ordinal],
[UnionAll1].[Name] AS ColumnName,
[UnionAll1].[IsNullable],
[UnionAll1].[TypeName],
ISNULL([UnionAll1].[MaxLength],0) AS MaxLength,
[Code] ......
I made a quick Google search and found this [URL] ....
It sounds as an interesting idea to try although I am not sure it will work with POCO Generator. But I'm going to try it now anyway.
Hi All,
I have created a table using VIEWS in SQL server 2005, now i want to be ablle to edit it in a datagrid but i cannot do so as i there is no primary key!
now does anybody know how to set a primary key constraint so i can set one of the fields as a primary key to identify the row?
many thanks
I have the following fields in table A:
GL_ID|GL_Name_VC | Amount |Period_TI|Year_SI
===================================================
1000| Inventory| 8,000.00 | 01 | 2005
===================================================
1000| Inventory| -3,000.00 | 02 | 2005
===================================================
1000| Inventory| 5,000.00 | 02 | 2005
===================================================
the fields above have the following datatype:
Fields | Datatype
===================================
GL_ID | Integer
GL_Name_VC | Variable Character
Amount | Integer
Period_TI | TinyInteger
Year_SI | SmallInteger
The above database is running on Microsoft SQL Server 2000 and i would like to query
for a report that looks something as below:
GL_ID | GL_Name_VC |Op Bal|Period_Dr|Period_Cr|Period Bal|Closing Bal
======================================================================
1000 | Inventory |8,000 | 5,000 | -3,000 | 2,000 |10,000
The above report has an Op Bal column which is the sum of all amount in Period 01 in
Year 2005 carried forward as opening balance in Period 02, Period_Dr Column would contain
all positive amount in Period 02 & Period_Cr Column would contain all negative amount
in Period 02. Period Bal is the summation of both Period_Dr & Period_Cr and Closing Bal
column is the summation of Op Bal + Period Bal.
Guys, hope someone out there can help me with the sql command for the above report?
Hi,
the query below (from Adventure Works) displays the sales amount for three products and a custom member "aggregation" which is the aggregate of these three products, and it cross joins with the attribute "colour".
Code Snippet
with member [Product].[Product Categories].[Subcategory].&[31].[aggregation] as 'AGGREGATE({ [Product].[Product Categories].[Product].&[214], [Product].[Product Categories].[Product].&[215], [Product].[Product Categories].[Product].&[220] })'
SELECT { [Date].[Calendar].[All Periods] } ON COLUMNS ,
NON EMPTY { { { [Product].[Product Categories].[Product].&[214], [Product].[Product Categories].[Product].&[215], [Product].[Product Categories].[Product].&[220],[Product].[Product Categories].[Subcategory].&[31].[aggregation] } * { [Product].[Color].[All Products].CHILDREN } } } ON ROWS
FROM [Adventure Works]
WHERE ( [Measures].[Reseller Sales Amount] )
Can someone please explain me why I'm getting this result:
All Periods

instead of something like this:

and also if anyone knows of a possible way of getting the second type of result?
please note that if I create a custom member that aggregates members of any other level of the Product Category hierarchy, the problem doesn't exist (see code and results below)
Code Snippet
WITH MEMBER [Product].[Product Categories].[Category].&[4].[Aggregation] as

I'd like to have all distinct recordIDs with relevant text associated with them. Each record has 3 text boxes in different languages. Each text in different language is defined by an AttributeDefinitionID. This is my query:
Select a.entryID, g.GroupName, c.CategoryName as ExperienceType,
e.AttributeValue as EnglishWording,
e1.AttributeValue as GermanWording,
e2.AttributeValue as RussianWording,
From Entry as a
inner join entrycategory as b on b.entryid = a.entryid
[Code] ....
but in the results I get additional rows for each record even if the record doesnt have all three text boxes populated and there is only EnglishText for example.
EntryID GrouPName EnglishWording GermanWording RussianWording
1586 Red abc NULL NULL
1586 Red NULL NULL NULL
3566 Yellow NULL Hallo Welt NULL
3566 Yellow NULL NULL NULL
3566 Yellow Hello world NULL NULL
3566 Yellow Hello world Hallo Welt NULL
1586 should only return the first line with English wording.
3566 should return the last line that shows both English and German wording populated
Hello,In my table, I have two columns - ForecastSales and ActualSales. I needto write a query that returns me just one aggregate value (one row andone column). If sum(ActualSales - ForecastSales) is negative, I need toreturn "red." Otherwise, I need to return green.I looked at CASE statement. However, I could not figure out anefficient way to build this query. I would appreciate your help.Thank you in advance for your help.Pradeep
View 3 Replies View RelatedHi,
I have a question about how to best make a comparison of two aggregated SELECT€™s. I'm using SQL Server 2005 on a Windows XP machine.
I€™m doing a comparison between donor/gift information from one table and donor/gift information from another table. I have a difference of 7 records/gifts between the two tables. For whatever reason one table is supposedly Header level data and the other is Line level data and they are supposed to have the same number of records/gifts (not an issue here).
The aggregated SELECT€™s, which will show the donor and the number of gifts each made, are listed below:
SELECT
[Account Number]
,count(*) as [Count]
FROM
Zk_HeaderMulti
GROUP BY
[Account Number]
--
SELECT
[Account Number]
,count(*) as [Count]
FROM
Zk_LineMulti
GROUP BY
[Account Number]
Is there a more efficient way to do this than the below listed method in which I use temp tables, join them and find the donor(s) with differing number of gifts between the header table and the line table?
=================================================
SELECT
[Account Number] as Line_Donor
,count(*) as LineGift_Num
INTO
#Line
FROM
Zk_LineMulti
GROUP BY
[Account Number]
--
SELECT
[Account Number] as Head_Donor
,count(*) as HeadGift_Num
INTO
#Header
FROM
Zk_HeaderMulti
GROUP BY
[Account Number]
--
SELECT
Line_Donor
,LineGift_Num
,Head_Donor
,HeadGift_Num
FROM
#Line A
JOIN
#Header Z
ON a.Line_Donor=z.Head_Donor
WHERE
LineGift_Num<>HeadGift_Num
==================================================
I thought I might be able to try and do it in a single query that doesn€™t require two temp tables, but took the easy way out. Any suggestions?

I would like to use the following SQL statement to get the latest
comments for all products.
Code Block
SELECT PRODUCT_ID, COMMENT, UPDATED_ON
FROM PRODUCT_COMMENT
GROUP BY PRODUCT_ID
HAVING UPDATED_ON = MAX(UPDATED_ON)
But this leads to the following error:

Column 'PRODUCT_COMMENT.UPDATED_ON' is invalid in the HAVING clause
because it is not contained in either an aggregate function or the
GROUP BY clause.
Is there a way to do that?

I have a datasource view DSV1. It points to a datasource DS1 that is considered the "primary".
I have created a Report Model that uses DSV1 (and thus uses DS1)
I created a new datasource, DS2 that I would like to use instead of DS1. (I can't just modify DS1 because if I modify it, it will overwrite it when we go to our Production environment and break that datasource)
So, I can go into DSV1 and change all the references from DS1 to DS2.
But that's where the problem lies.
When I try to build, I get the following error:
"The Table property of the Entity "E1" refers to the Table "dbo_View", which is not in the primary data source."
Somehow, the entity is tied to the "primary" datasource. When I change it back to DS1, everything works fine. Any thoughts? What can I do?

Hi all,

Hi,
I have recently been looking at a database and wondered if anyone can tell me what the advantages are supporting a unique collumn, which can essentially be seen as the primary key, with an identity seed integer primary key.
For example:
id [unique integer auto incremented primary key - not null],
ClientCode [unique index varchar - not null],
name [varchar null],
surname [varchar null]
isn't it just better to use ClientCode as the primary key straight of because when one references the above table, it can be done easier with the ClientCode since you dont have to do a lookup on the ClientCode everytime.
Regards
Mike
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?

I have the following table
CREATE TABLE [dbo].[property_instance] (
[property_instance_id] [int] IDENTITY (1, 1) NOT NULL ,
[application_id] [int] NOT NULL ,
[owner_id] [nvarchar] (100) NOT NULL ,

[owner_type_id] [int] NOT NULL ,
[property_value] [ntext] NOT NULL ,
[date_created] [datetime] NOT NULL ,
[date_modified] [datetime] NULL
)
I have created an 'artificial' primary key, property_instance_id. The 'true' primary key is application_id, owner_id, property_id and owner_type_id
In this specific instance
- property_instance_id will never be a foreign key into another table
- queries will generally use application_id, owner_id, property_id and owner_type_id in the WHERE clause when searching for a particular row
- Once inserted, none of the application_id, owner_id, property_id or owner_type_id columns will ever be modified
I generally like to create artificial primary keys whenever the primary key would otherwise consist of more than 2 columns.
What do people think the advantages and disadvantages of each technique are? Do you recommend I go with the existing model, or should I remove the artificial primary key column and just go with a 4 column primary key for this table?
Thanks Matt
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.

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

View 1 Replies View RelatedA 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?

Hello all,I'm taking over a project from another developer and i've run into a bit of a problem. This developer had a bad habit of not using primary keys when designing various databases used by his programs. So now i've got approx 1000 tables all of which do not have primary keys assigned.

Hi..
I'm going to build database of university, but I have problem with primaru key,
This is the situation:
there are many faculities and each one has many departments,
each department has many courses,
each course has many sections..
The problem:
I want to make those fields in the same table and make the primary key generate from other fields,
(i.e)
I want the faculity be integer from 4 digit "Example the first faculity start with 1000 the second 2000 and so on" and the the department of each faculity will generate its value from the faculity number+interger number from 3digit "Example the department of the first faculity start with 1100 and the second on will be 1200 and so on "
the same thing will repeate for courses and sections so the sectionsID will be the primary key.
Do you know hoew this idea can be implement by SQL server 2005?
Please help me as soon as possible.

I am setting up some tables where I used to have an identity column as the primary key. I changed it so the primary key is not a char field length of 20.
Is there going to be a big performance hit for this? I didn't like the identity field because every time I referenced a table I had to do a join to get the name of object.

This is a very basic example, but you get the idea of what I am referring to.
Any thoughts?

I need to create my own primary key, how do I go about doing that?? In the database I am working in usually has a primary key that looks like this VL0008
the V is for Vendors, thats basically their number. Some of these Vendors need to be licensed and some dont, the ones that are not licensed dont get a number but I am to use that as the Primary/Index key I need to create one for those particual vendors. How can I go about doing that??? I was wanting to make it TL888 something like that.
