Using A Sub Query To Return Relational Data
Jan 19, 2008
Hi i am trying to use this query to pull all the publications stored in the database and all the authors contributing to that publication (1 to many relationship). I am trying to use a sub query so that i can display the results on one row of a gridview (including a consecutive list of all the authors). However i am recieving this error: Incorrect keyword near the word SET. ?
Maybe i need to add a temp column in the sub query to pull all the related authors for a single publication - but i dont know the sql for this? can anyone help?
Thanks
SELECT ISNULL(Publication.month, '')+ ' ' + ISNULL(convert(nvarchar, Publication.year), '') as SingleColumn, Publication.publicationID, Publication.title FROM Publication WHERE Publication.publicationID IN (SELECT (convert(nvarchar, Authors.authorName)) FROM Authors INNER JOIN PublicationAuthors ON Authors.authorID = PublicationAuthors.authorID) AND Publication.typeID IN (SELECT PublicationType.typeName FROM PublicationType INNER JOIN PublicationType ON Publication.typeID = PublicationType.typeID

Hi all,
I am trying to create a diagram for our database, during the creating, I create some of the relationships which were not there(basically our original database is not relational database, that's why I am doing it)
So sometimes I have to chage data type in order to create a relationship for the coloumns in different tables. i.e. change char(16) to varchar(7) (I checked the field that make sure all the data in this field is <= 7 characters)
But when I saved the diagram, there is an error message that state:
Errors were encountered during the save process. Some of your database objects are not saved on your diagram.
'agent' table saved successfully
'VisitUSA' table
- Unable to create relationship 'FK_VisitUSA_agent'.
ODBC error: [Microsoft][ODBC SQL Server Driver][SQL Server]ALTER TABLE statement conflicted with COLUMN FOREIGN KEY constraint 'FK_VisitUSA_agent'. The conflict occurred in database 'CMC', table 'agent', column 'AgentCode'.
What does that mean? is it caused by some of the agentcode data in VisitUSA table which is not in agent table?
Thanks!

Hi all! I am working on a piece of SQL at the moment and I'm getting a little confused. I have 3 tables: Items, Attributes and a table linking them. I have 5 attributes and an item can have any of the 5 attributes. So my linking table holds the ItemID and the AttributeID and there can be 1-5 entries for each Item. A user can search for items based on Attributes; so they can tick 5 checkboxes that represent the 5 Attributes. So I need to build a query based on their choices. At the moment I'm using:Select * FROM ItemsINNER JOIN linking on Link_ItemID = Item_IDWHERE Link_AttributeID IN (10, 13, 17)But this brings out the Item that have either AttributeID of 10 or 13 or 17 whereas I need it to pull out ONLY items that have a AttributeID of 10 AND 13 AND 17.Can anyone help with this query? Sorry if this is badly worded. The solutions is prolly something really simple I have overlooked... :SI've also tried:Select * FROM ItemsINNER JOIN linking on Link_ItemID = Item_IDWHERE Link_AttributeID = 10 AND AttributeID = 13 etcBut obviously that won't work! :s

I have a few questions for you guys. I have a client
application that can be offline or online. While offline, records can be added and need to be later synced to production.
I will use rda to pull the table down, and this is working fine. Now what if I
have multiple tables where I want a foreign key relationship?
With rda I can only pull down one table at a time from
everything I've read. Now say create a constraint after pulling the two or more tables down. While in offline mode I create a new record on two seperate tables with foreign key/primary key relationship.
When I do the push to the server will it automatically
update the foreign key reference (locally) to the right one on the production
server? Or will I get a duplicate primary key error? On the production server the primary key will be different because of the identity. This is very important because I will have multiple clients.
Thanks in advance

I am just now starting the switch from .NET 1.1 to .NET 2.0. I really like the new way of using the SQLDataSource and setting up Views declaratively as opposed to doing it all in code, which brings me to my question.In some of my applications I have a single Stored Procedure return multiple result sets to a single DataSet where I have a DataRelation set up. Then I can have nested DataGrids that use the GetChildRows() method to filter the results to display the hierarchical data. I would like to do something similar with the SQLDataSource and GridViews but haven't found a way to get multiple result sets.One thought I had was to create a Strongly Typed Dataset and then use the ObjectDataSource object, but I still didn't see a way to get child rows out of the datasource. I've seen an example that uses a <FilterParameter> to get nested data, but there is an extra trip made to the server for each parent item as it just put an extra parameter in the WHERE clause of the query.

I have cubes that hold quite a few calculations and so creating Excel pivot table views from it take a long time. This is even true for Excel 2007.
Now I wonder if it would be possible to write back all the calculation results to a relational table - maybe one that exactly matches the report format - so creating another report would be much faster?
SSRS seems to be a way to go but it does not speed up my Excel case.
I read about write-back in ROLAP and MOLAP but I don't think any of these concepts help me to really speed up my reports.
The closest thing I was able to find so far, which besides seems to do exactly what I want is Microsoft's new PerformancePoint 2007. It's just it seems overkill for my projects and the price is at $20K.
Any suggestions are appreciated.

Hello everyone, this is my first post here so hopefully I am not asking a common question.
I am trying to create a flat dataset in SQL 2005. Basically I run a query and I get multiple rows for the same primary key. The query I am running is quite large and has several different tables connected to it, here is a small sample of what it looks like...
Typeid(Primary Key) Individual Address
1 Sam 912 Ave. J
1 Sam 913 Ave. Q
1 Sam 914 Ave. R
2 Mike 1000 Ave. O
3 Jill 1001 Ave. O
I want it to kind of look like this
TypeID Individual Address_1 Address_2 Address_3
1 Sam 912 Ave. J 913 Ave. Q 914 Ave. R
2 Mike 1000 Ave. O
3 Jill 1001 Ave. O
As I said before, this query is pretty big, and has several variables like Address where multiple rows are being taken by one Primary Key.
If it is not possible to do this in SQL 2005, is there a program that may be able to? Right now we are using SPSS as sort of a bandaid... we run the query in small portions like the one in the sample and then restructure the in sections but this takes several hours.
Anyways, thanks for any help that you may be able to provide.

I am searching for a way to fast load relation data. I know how to load data fast but how can i store relation data fast.
For example :
Table1 ( tabel1Id int identity , name varchar(255) )
Table2 ( tabel2Id int identity , table2Id , name varchar(255))
When i insert 50 records into Table1 i can't get the 50 identity fields back, to insert the related data into Table2.
I think one of the solutions could be returning a selection of
Table1 joined with syslockinfo, but i have no idea how to do it.
Does anyone have an idea?

Hi,
I have played around with SSIS in addition to reading an SSIS book front to back, but I am still a little confused as to how to import an Xml file with relational data.
The Xml file is structured as follows:
<products>
<product>
<name>
<id>
<category>
<name>
<id>
</category>
<fields>
<field>
<name>
<value>
</field>
<field>
<name>
<value>
</field>
</fields>
</product>
</products>
Basically I want to import the Xml data into three tables: categories, products and fields. A product can belong to one or more categories and has one or more fields which store information about the product.
Using the Xml Source component I can load the Xml from the file, but I can only output one section (category, product or field) at a time. Since the relationship is infered from the hierarchical structure of the Xml (e.g. the fields don't store an ID of the product they belong to), I am not sure how to import the relationships into my tables.
If anyone has any tips on how I can go about that, then it would be most appreciated :)
Thanks!

I believe saving prediction query results to relational tables is possible (the BI studio does it!). I am not clear on how to do this w/o the BI studio, which means if I write a DMX query and want to store its output to a relational table, how do I do it?
Tips, anyone?

Ok, I have a page on my website where we can add products to our database. We are a music store, and most products have different versions or colors. I've created 2 tables, Products and Subproducts. The products table may hold info like Fender Stratocaster, and the subproducts would hold colors (Blue, Sunburst, etc). The subproducts table has an integer field called MainProductID, which is linked to the mainproducts table field RecordID. So far the page uses a wizard where if first creates the main product using an sql datasource. After the data has been added to the main products table, my page gives you the opportunity to add different sub products. The problem I am having is actually feeding in the RecordID from the main products table to my insert parameter on the sub products data source. This is what I have tried so far: There is a formview on the page that is bound to the main products table, after the entry is created I can physically see the info on my screen, so I know the data is there at my disposal SubProductsDataSource.InsertParameters.Add("@MainProductID", Formview1.datakey.item("RecordID"))SubProductsDataSource.Insert()Using this adds the data to the table, but the MainProductID is nullalso is there a cheap little way to refresh a page, because when I upload the product images I have it go to the next step where you are supposed to be able to see the images you uploaded, I don't see them which makes me think that the page is loading faster than the images are uploading. Thanks

Problem:
I am working on a price comparison system which matches the best prices for a purchase (or an order) from exisiting purchase data.
The order is stored in multiple tables including order details (stores major items purchased: e.g., PC) and order sub-details (optional items purchased with the major items: e.g., speakers, backup device, webcam etc.).
There could be a number of major items in an order and each major item could have multiple related sub items. The other variables that affect the price include trade-ins if any, sales going on at the time of order, number of units etc.
Now, for any new configuration (major items/related sub items), the system should be able to return a list of previous purchases made with similar configurations, and similar variables (quatities, trade-ins etc). Even if the same model is not present, similar pcs by the same vendor should be considered. etc etc.
Questions:
Is this possible using Data mining?
If yes, which algorithm is recommended?
Also, can I assign/modify any kind of weights to certain variables (if same model: .6 ; if same model not available but pcs made by same manufacturer available: .3 ; by other manufacturers: .1)?
Any help will be greatly appreciated.
Thanks,
Jojy

I have two tables that share a common identity row. I need to build a query where data that exists in one table does not contain data in the other table. For example, table 1 has columns of Owner_ID, LastName, FirstName and table 2 has columns Auto_ID, Owner_ID, AutoMake. Both tables are joined by the Owner_ID column. I need a query that provides all owners from table 1 who do not have an entry in table 2.
Thanks in advance,

I'm having a bit of a trouble explaining what I'm trying to do here.
I have 3 "source" tables and a "connecting" table that I'm going to use
tblContacts - with contactID, ContactName etc
tblGroups - with GroupID, GroupName
tblSubGroups - with SubGroupID, GroupID and SubGroupName (groupID is the ID for the parent Group from tblGroups)
They are related in a table called
tblContactsGroupConnection - with ContactID, GroupID and SubGroupID
One contact can be related to many subgroups.
What I want is a list of all contacts, with their IDs, names and what groups they are related to:
ContactID, ContactName, [SubGroupName1, SubGroupName2, SubGroupName3]
ContactID, ContactName, [SubGroupName1, SubGroupName3]
ContactID, ContactName, [SubGroupName3]
I'm sure there's a simple solution to this, but I can't find it. Any help appreciated. :)

Hi ! I have a textbox and a Search button. When the user inputs a value and press the button, i want a datagrid to be filled.
The following code runs:
Dim connect As New Data.SqlClient.SqlConnection( _
"Server=SrvnameSQLEXPRESS;Integrated Security=True; UID= ;password= ; database=dtbsname")
connect.Open()
Dim cmd As New SqlCommand
Dim valor As New SqlParameter("@valor", SqlDbType.VarChar, 50)
cmd.CommandText = "Ver_Contactos_Reducido"
cmd.CommandType = CommandType.StoredProcedure
cmd.Connection = connect
cmd.Parameters.Add(valor)
cmd.Parameters("@valor").Value = texto
Dim adapter As New SqlDataAdapter(cmd)
Dim ds As New System.Data.DataSet()
adapter.Fill(ds)
GridViewContactos.DataSource = ds
GridViewContactos.DataBind()
connect.Close()
I drag a datagrid on the page and only changed its Id.
Into the SQL database the stored procedure is the following:
ALTER PROCEDURE [dbo].[Ver_Contactos_Reducido]
(@Valor VARCHAR(100))
AS
BEGIN
SET NOCOUNT ON;
SELECT NombreRazonSocial, Nombre, Apellido,TelefonoLaboral,
Interno, TelefonoCelular, Email1, Organizacion
FROM CONTACTOS
WHERE NombreRazonSocial = @Valor OR Nombre = @Valor OR Apellido = @Valor OR TelefonoLaboral = @Valor OR Interno = @Valor OR
TelefonoCelular =@Valor OR Email1 = @Valor OR Organizacion= @Valor
END
When i run the page i can't see the datagrid, and after i enter a text and press the button, nothing happens. What am i doing wrong??
Thks!!

Hi,
I got a problem.
I installed Microsoft SQL Server Management Studio Express 2005 version.
And I created a Compact database.
I created an connection in SSMSE to connect the database and opened a query form.
then, i run the following sql:
Select * from Table1
It returned 3 records to me.
After that, I used program to insert record into this table.
Then i ran this sql again, it still show me 3 records.
I closed the query form, and re-created a new query form, then run the sql, it returned 4 records to me.
Why? It's very strange and difficult to operate, right?
Is there anyone know how to make the SSMSE to return whole records without any close query form and re-create query form operation?
Thanks a lot!
And Merry X'max!!!

How can I make sure that the record is deleted so that I can proceed with other jobs? How can I catch it in the program like from VB? Is there any return like true or false in SQL? :(

This has got to be a simple one, but I could not find out how
I have this simple proc for test purposes only...
ALTER PROCEDURE dbo.RotoTest( @strSSN VARCHAR(11), @blnUseACHDate BIT = 0, @intInvestorId int = 0)ASreturn 5
Thats right it does nothing but return 5 and thats because I removed all the real code to simplify my question.
When I hit this proc in SQL Query Analyzer..
exec RotoTest '123-45-6789', 0, 1 No return value is displayed in Query Analyzer.
When I try something like this
exec RotoTest '123-45-6789', 0, 1, intRetValue Output (in this situation I get wrong number of arguments)
How can I get a return value displayed on my screen in SQL QUERY ANALYZER with out modifying the proc? I do not want to modify the proc in anyway (because I can't), I just want to display the return value

Hi
I have written a query for viewing the results of an on-line survey. I have three tables involved in this query: answers, answerpossibilities and users. So I use a few joins and made this query:
ALTER PROCEDURE dbo.GeefAntwoordenMeerkeuze ( @question_id int ) AS SET NOCOUNT ON; SELECT answerpossibilities.answerpossibility_content AS[Answerpossiblity], COUNT(answers.answers_id) AS [Times chosen] FROM answers right OUTER JOIN answerpossibilities ON answers.answerpossibility_id = answerpossibilities.answerpossibility_id left join users on answers.user_id = users.user_id WHERE ((answerpossibilities.question_id = @question_id AND nswerpossibilities.answerpossibility_content!='-- choose answer --')) GROUP BY nswerpossibilities.answerpossibility_content ORDER BY [Times chosen] desc
The above query works fine. The data returned by this query is shown in a gridview. When an answerpossibilty was never chosen it shows 0 as times chosen. So that's fine. But the problem is, only answers of users who completed the survey should be shown. In the users table there's a field user_completed. So the query should check whether this field is 1 (true).
ALTER PROCEDURE dbo.GeefAntwoordenMeerkeuze ( @question_id int ) AS SET NOCOUNT ON; SELECT answerpossibilities.answerpossibility_content AS[Answerpossiblity], COUNT(answers.answers_id) AS [Times chosen] FROM answers right OUTER JOIN answerpossibilities ON answers.answerpossibility_id = answerpossibilities.answerpossibility_id left join users on answers.user_id = users.user_id WHERE ((answerpossibilities.question_id = @question_id AND nswerpossibilities.answerpossibility_content!='-- choose answer --') and users.user_completed = 1) GROUP BY nswerpossibilities.answerpossibility_content ORDER BY [Times chosen] desc
Using this query only answers of users who completed the survey are shown but answer possibilities that were never chosen are no longer shown with 0 as times chosen. The gridview simply doesn't show them anymore.
Thanks for helping me!

Does sql server have a mechanism (aside from count()) that for any given SELECT query will tell you only how many rows it will return without actually returning the data?
The reason for this is that we have a generic lookup form in an application that is used on almost every screen (we have a lot of screens, so it gets a lot of different, sometimes complicted, queries passed to it to use for the lookup, and having to manually edit the query to use count over all the select clauses doesn't seem like the best way to handle this. If we could do a kind of 'trial run' against the server just to get the number of rows and use that to help set up the form, that would be ideal.
