Failed To Add Relation(s). An Item With The Same Key Has Already Been Added
Jun 6, 2007
I am developing a small project that converts a dataset to an equivalent structure in SqlCe. The application converts every field, table and constraints to SqlCe, decomposing de dataset structure into Sql sentences.
The application works fine, the tables and constraints are reconstructed without error. but I found some issues:
After conversion, the usual test is to connect to SqlCe, using Data->Add New Data Source and generate a dataset from the resulting tables.
I found that some tables throw the following message:
Failed to add relation(s).An item with the same key has already been added.
After that, the dataset returned contains the tables, but not the relations.
After some trial I found that Data Source Configuration Wizard (DSCW) has some problem with foreign keys using Primary keys with multiple fields. If I drop that foreign keys, DSCW inferes the dataset without problem.
Interesting note: I am able to convert the dataset to an Sql Server using the same Sql sentences. If I use Data Source Configuration Wizard I have no errors.
Any advise to understand of fix this problem will be aprecciated.
Is that a bug from DSCW ?
Thanks
Fernando

Not 100% sure how to do this so I would appreciate some directions. I have 2 tables, Systems and Contacts. A system can have 1 to infinite contacts and contact can have 1 to infinite systems. So I use a 3rd table Sys_Con to add the contact needed for each system.
Now my question is once I add the System and contact how do I know for sure which ContactID to add in my Sys_Con table? Because while I am doing this operation maybe someone can add an other contact. So is there a way for my store proc Add_Contact to return the contactID needed for my store proc Add_Sys_Con ?
TABLE Sys_Con
SystemID int
ContactID int
Table Contact
ContactID int Identity
ContactName
...
Table System
SystemID
...

I am getting this error when clicking-through in Report Builder on a report using a report model as the data source -
An item with the same key has already been added.
I searched for the error but came up empty in the SSRS space. Does anyone out there know when this is generated and where I need to look in my model/properties to see what I have set incorrectly?
A little background/detail - It's a simple report against two fields (type & #count) in one entity (customer) in a (guessing here) medium sized model (~16 transactional/fact entities, ~40 lookup entities, ~15 what I am calling domain entities). The entity has 5 DefaultDetailAttributes, one Identifying. The report has 2 fields type (a lookup role) and #customers in the data area (so I can click it to test the click through). Then I click the # Customers to look at the detail for those X customers and after a long while and no queries against the DB (I have profiler running) I get this error.
Thanks in advance for the help.

Hi there,
I have a search page that redirects to another page transfering the search terms in a querystring. In the page to display the search results I use SQL parameters to show the results. Everything runs fine until I do a page refresh or use paging to bring up another set of results.
Everytime I try to refresh/page etc. I get the following error:
Item has already been added. Key in dictionary: "@CityTown" Key being added: "@CityTown"
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Any sugestions that anyone could provide would be greatly appreciated. This error obviously renders the search features useless.
Thanks in anticipation,

I'm getting this warning each time I auto-generate my model. I'm using named queries with logical primary keys.
The relation property of the role "xxx" refers to the target end of relation "xxx" which is not bound to a set of uniquely contrained columns.
I've searched and can't figured out what I am being warned about and whether I need to fix something. Can you help?
Thanks,
Toni

Hi,
Here's my problem. I have 2 tasks defined in my Control Flow tab:
EXECUTE SQL--------->EXECUTE DTS 2000 PACKAGE
When I attempt to run it, by right-clicking the EXECUTE SQL task, and selecting "Execute Task", it only runs the EXECUTE SQL part (successfully), and does not "kick off" the EXECUTE DTS 2000 PACKAGE, after it is done running (even though it completes successfully, as shown by the green box).
Yes, they are connected by a dark green arrow, as indicated in my diagram above.
Why is this?? Am I missing something here? Need help.
THANKS

I am having trouble finishing the last bit of a report. The report shows orders that customers have placed that contain 0 promo items, All promo items (all items in order are promo items), and a mix of promo and non promo (at least 1 promo item and 1 non-promo item). Ive simplified this a bit for ease of understanding but lets assume we have 2 tables: A Promo table that contains the items on promotion and the dates that promotion is valid, and a Sales table, that contains the order number, order date, and sku ordered.
I've already written code that finds orders that have at least 1 promo item in them, and using that, I can determine what orders have 0 promo items in them. Where I am stuck is taking the orders that have at least 1 promo item in them, and separating them into orders that have only promo items, and those that have both promo and not promo items in them. Also, there are several promos throughout the year (called "Offers") so in my code below, you can see 2 different Offers ("JF" and "MA") with their corresponding dates they are valid. They will never overlap. My results also have to be split out by Offer so management can look at the results of each offer separately. Here is some code:
Code:
create table #Promos (
Offer varchar(2) null,
SKU int null,
StartDt date null,
EndDt date null
[Code] ....
So my results should show OrderNo A1111 in the Promo and No Promo group because of SKU 5 not being promotional during the time that order was placed. OrderNo A2222 should be in the Promo Only group because both SKUs on the order were promotional at the time the order was placed.

This one shouldn't be too hard to do, just can't seem to figure it out.
I have two tables
tNames which contains 'ID' and 'Name'
tLocations which contains 'ID' and 'Location'
each ID may be associated with many Locations
I want to run a query to display these results:
[ID, Name, Location]
but only to return the first Location associated with that ID (or the max, min, I don't really care as long as it's only one result)
right now I have
Code:
SELECT tNames.ID, tNames.Name, tLocation.Location
FROM tNames INNER JOIN tLocations
ON tNames.ID = tLocations.ID
but this returns a new row for each different Location of the same ID
Thanks.

Hello,I'm relative new to sql and databases and the last few weeks I learnedmyself a lot. I'm trying to make a hotel reservation application.I have a database with a table Booking, a table Room, a tableRoomsPerBooking. So a booking contains date/time etc and a fieldRoomsPerBookingID. The table RoomsPerBooking contains number ofpersons, unitprice etc. and a field ID and a field RoomID. The tableRoom contains data like name, notes etc.now i have two questions:First about relations:The table Booking has relationship: PK table RoomsPerBooking - ID <-->FK table Booking - RoomsPerBookingID.The table RoomsPerBookingID has relationship: PK table Room - ID <-->FK table RoomsPerBooking - RoomIDIs this relationset good for my purpose? I think it is, but I am notsure.The second question is:How do I get available rooms per nightI came this far.... what are the "some statements"?CREATE PROCEDURE dbo.GetAvailableRooms(@BeginDate DATETIME,@EndDate DATETIME)ASSELECT Room.*FROM RoomWHERE Room.ID NOT IN (SELECT DISTINCT room.IDFROM Room room JOIN RoomsPerBooking roomsPerBookingON room.ID = roomsPerBooking.RoomID--Some statements--WHERE booking.FromDate <= @EndDateAND booking.ToDate >= @BeginDate)GO

Hi
I have about six different entities that can have zero or more note entities associated with them. The easy way to do this is obviously to have a different "note" table for each of the entities i.e. WorkItemNote, CustomerNote etc.. But I would much rather have a single "note" table since they would all be identical, so I came up with this design:
CREATE TABLE WorkItem
(
WorkItemGuid uniqueidentifier PRIMARY KEY DEFAULT (newid()),
-- rest of table declaration removed for bravity
)
CREATE TABLE Customer
(
CustomerGuid uniqueidentifier PRIMARY KEY DEFAULT (newid()),
-- rest of table declaration removed for bravity
)
CREATE TABLE Note
(
NoteId int IDENTITY(1,1) NOT NULL PRIMARY KEY,
ReferenceGuid uniqueidentifier NOT NULL,
Text ntext NOT NULL,
-- rest of table declaration removed for bravity
)
This way I can get notes associated with a given entity, either Customer or WorkItem, by just selecting from the Note table with its WorkItemGuid or CustomerGuid.
My question is: Is this the best approach to what I am trying to accomplish?
(ps: Apologies if "many to one" is not the right terminology)
Regards, Egil.

Hi,
I am new to sql and is working with sql server managment 2005 +c# 2005.
My application needs to create a blockdiagram sort of thing say
if in my database i got a table 'Addition' with 'a', 'b', 'c',and the primary key addition_id, and c is related to a and b as c = a+ b.
there is stored procedure name usp_addition which contains this relation. Each time any insert or update is done this sp is executed and all the values are updated for accordingly.
My problem starts in the front end where i need to draw the graphical representation of table addition.
In this graphical representation, I need to draw the labels a, b, c and the arrows from a and b which will connect to c, showing that c has a, b as inputs.
I got the label using dataset and datacolumns but hte problem is how to create the arrows the name of labels (i.e my column names from which the arrow should start and end)
How does I get the information that c as two inputs a, b. I dont need the values since i just want to view the columns in table and which column is input to another column.
Since I need to do this dynamically because my tablename, and the number and name of column would differ does any body knows how to do this.

Hi,
I have two tables.
CREATE TABLE Service(
SERVId varchar (10) NOT NULL,
SERVName varchar (30) NOT NULL,
SERVDesc TEXT NULL,
PRIMARY KEY(SERVId)
)
CREATE TABLE New(
SERVId varchar (10) NOT NULL,
NDId varchar (10) NOT NULL,
NDName varchar (30) NOT NULL,
NDDesc text NULL,
PRIMARY KEY(SERVId,NDId)
FOREIGN KEY(SERVId)
REFERENCES Service(SERVId)
)
Msg 547, Level 16, State 2
DELETE statement conflicted with COLUMN REFERENCE constraint 'FK__Newdev__SERVId__4939E6D2'. The conflict occurred in database 'test', table 'New', column 'SERVId'
Command has been aborted.
The same problem occurs even if the second table i.e. new is declared as follows, i.e created with only one primary key:
CREATE TABLE New(
SERVId varchar (10) NOT NULL,
NDId varchar (10) NOT NULL,
NDName varchar (30) NOT NULL,
NDDesc text NULL,
PRIMARY KEY(NDId)
FOREIGN KEY(SERVId)
REFERENCES Service(SERVId)
)
what might be the problem? But the same relation works on MS Access.
Is there anyother way of declaring this kind of relationship i.e. primary and foreign key?Can anyone pl. help me in solving this problem of foreign key relation.
thanks in advance

Hi Group,(I am just starting with SQL Server 2005.)On SQL Server 7 I used often the nice relation schema, where I used todraw out the whole database, especially the Foreign Keys constraints.I found these relational schemas very handy to study an old database Ibuild a few years earlier that needs some updating.I tried to find such an utility in SQL Server 2005, but cannot find it.I did found the FK-constraints, but it is just an popup where I candefine them.The overview such a visual schema gave was really great and I miss it.Question: Is it gone in SQL Sevrer 2005, or do I just not know where tolook? If the latter, please guide me. :)Thanks for your time.Regards,Erwin Moller
