Linking Tables In Data Set Or Stored Procedure
Mar 10, 2008
Im currently in the process of developing a new system in ASP.net. The system uses multiple tables from a SQL database. To link information from say the products table to the suppliers table a unique key from the suppliers table is stored in the products table to show which products each supplier has bought...simple so far.
From this I can then pull out any of the information relating to that product instead of just displaying the ID. Currently this is done by creating a stored procedure and then dragging the stored procedure onto the dataset layer to create the data adapter.
Im not 100% this is the best way to be doing this. Is it possible to simply just link the tables in the dataset layer to display a string from another table instead of an ID referencing number?!
any help on this would be much appreciated as I cant really continue untill I have sorted out the data structure problems.
Thanks in advance

Hi can anyone help me with the format of my stored procedure below.
I have two tables (Publication and PublicationAuthors). PublicaitonAuthors is the linking table containing foreign keys PublicaitonID and AuthorID. Seeming as one Publication can have many authors associated with it, i need the stored procedure to create the a single row in the publication table and then recognise that multiple authors need to be inserted into the linking table for that single PublicationID. For this i have a listbox with multiple selection =true.
At the moment with the storedprocedure below it is creating two rows in PublicaitonID, and then inserting two rows into PublicationAuthors with only the first selected Author from the listbox??? Can anyone help???ALTER PROCEDURE dbo.StoredProcedureTest2
@publicationID Int=null,@typeID smallint=null,
@title nvarchar(MAX)=null,@authorID smallint=null
AS
BEGIN TRANSACTION
SET NOCOUNT ON
DECLARE @ERROR Int
--Create a new publication entry
INSERT INTO Publication (typeID, title)
VALUES (@typeID, @title)
--Obtain the ID of the created publication
SET @publicationID = @@IDENTITY
SET @ERROR = @@ERROR
--Create new entry in linking table PublicationAuthors
INSERT INTO PublicationAuthors (publicationID, authorID)
VALUES (@publicationID, @authorID)
SET @ERROR = @@ERROR
IF (@ERROR<>0)
ROLLBACK TRANSACTION
ELSE
COMMIT TRANSACTION

Hi
I am currently developing my first database driven application and I have stumbled over some quite simple issue. I'll describe my database design first:
I have one table named images(id (identity), name, description) and one table named albums (id, name, description). Since I'd like to establish a n:n connection between these, I defined an additional table ImageInAlbum (idImage, idAlbum). The relation between these tables works as expected (primary keys, foreign keys appear to be ok).
Now I'd like to insert data via a stored procedure in sql server 2005 and I'm not sure how this procedure will look like.
To add a simple image to a given album, I am trying to do the following:
* Retrieve name, description from the UI
* Insert a new row into images with this data
* Get the ID from the newly created row
* Insert a new row into "ImageInAlbum" with the ID just retrieved and a fixed Id from the current album.
I know how I would do the first two things, but I am not used to Stored Procedures syntax yet to know how to do the other things.
Any help is appreciated ... even if it means telling me that I am doing something terribly wrong

Hi I am a complete sql newbie :)
With that being said I am trying for the life of me to link to a table in another sql database.
For some reason its not letting me link the table instead it is creating a query of the table.
I used the Access upsizing wizard and the access front end.
*grumbles - just wish I could find the upgrading handbook that tells you if you used to do it this way now do it this way*
Thanks

URL...let's say every student in the left table, has a corresponding table to the right. If we were to take the average of all the classes in the corresponding table, how would you be able to transfer that in the table to the left, assuming there could be thousands of these individual tables.

I am no stranger to Databases, I worked a lot with MySQL but never really cared about proper DB design as long as it worked. Now I am playing with SQL in a ASP.NET project and want to get things done the right way.Let's say I have a Movies database. My movies can have multiple genres so I set my tables up like this:
[Movies]
MovieID
MovieName
MovieRelease
[code]....
Is this the proper way of doing things? The problem with this is when I want to enter a record manually I have to know the ID of the movie and the ID of the Genres of the movie. And what about naming conventions? By default the identifier is always Id, from my MySQL experience I liked naming it like the table, same goes with other columns. This is my T-SQL code for above tables in VS-2013.
CREATE TABLE [dbo].[Movies] (
[MovieID] INT IDENTITY (1, 1) NOT NULL,
[MovieName] VARCHAR (50) NOT NULL,
[MovieRelease] NUMERIC (18) NOT NULL,
CONSTRAINT [PK_Movies] PRIMARY KEY CLUSTERED ([MovieID] ASC)
[code]....

Hi and thanks for taking the time to read this. I get really confused really quickly when it comes to table linking, and I think I am doing it the hard way. I am going to show my stupidity and ask if there is a better way than what I do, because it takes a LOT of querying and seems like a huge waste.
In reality, I have about 20 tables to join like this, but I'm going to use three for the example:
"Main" Table
AcctNoNameHeightWeight
1Bob13
2Phil21
3Jim15
4Lisa22
"Height" Table
HeightIDHeightName
1Giant
2Tall
3Medium
4Short
"Weight" Table
WeightIDW_Name
1Skinny
2Normal
3Overweight
4Obese
What I have been doing is:
SELECT
Main.AcctNo,
Main.Name,
Height.HeightName,
Weight.WeightName
FROM
Main
INNER JOIN Height ON
Height.HeightID = Main.Height
INNER JOIN Weight ON
Weight.WeightID = Main.Weight
WHERE Main.AcctNo < 3
My question: is doing 20 INNER JOINS really the best way to do this with 20 tables, or is there some other way to link Main.Height to Height.HeightID that is less intensive?
Thanks again for reading, and in advance for any information or insight you can provide.

I have two tables, one for cases and one for inventors. When I query a case linked to the inventor table I get as many rows as there are inventors. Is there a way that I can get just one row for the case and have the inventors lists Doe, John; Doe, Jane; Buck, Jack? I usually export results to Excel and my people want the inventors in one column for certain reports.
I would search for it but I don't know what it's called.
Thanks,

In a database, I am creating a new db. From there, I am setting up thetables, so that I can eventually create a front end (usually access,but I may attempt to be brave and lose the shell.) Anyway, I want touse a table, read-only for a lookup. It exists in another database onour system. Is there a way for me to link it into this database that Iam working on? I would think of it like in access when you go to do anew table and you choose to link the table from somewhere else. Thatis what I want to do. Can anyone possibly step me through this?I know basics of sql server and like to learn.Thanks!

Hi,If you have lookup tables which are used by multiple tables (e.g.'City' lookup table might be used by the 'Employee' and the 'Company'tables) do we need to link it to both tables? Or can it sit by itselfand just referenced?Cheers,Jack

First off, I am a novice in regards to SQL server and have the rudimentary skills to navigate, execute, query under SQL Server Manager. So, please bear with me.
I am working on a program that was not developed by myself, it is for my business and the company that developed it has gone under, so I have no technical support. The program uses SQL Server and ASP.net. We had a recent hard drive crash and I am in the predicament of having to re-install a new instance of the server onto a new computer. I have the most recent saved "data" files within "Microsoft SQL server/MSSQL/Data" directory. It includes the master, model, MSDB, etc. files.
Long story short, I have been successful in making the program operational again and I can connect to the server properly. It even works when web connecting with internet explorer. The problem I am facing is that all of the data is missing. When I connect through SQL Server Manager, I can see that there are two databases, I will name them "data1" and "data2". When I run a query of the tables, all the data is in "data2". All the stored procedures and tables are identical in both "data1" and "data2".
I am assuming (hopefully I'm right) that "data1" and "data2" are somehow linked or joined in some way. Any insight in how to get these two tables to link would be very much appreciated. Again, I am a novice, and will need help with specific coding that I can put into a query window and execute.
Thanks in advanced.

I'm new to SQL Server 2000. I decided to purchase this server because my old company (UPS) used the server to help expedite queries and manage on-line reporting. So, now it's up to me to utilize and understand the new server. I have been using MS Access as my front-end for several ad-hoc databases, so I'd like to keep utilizing this method. I want to test my first database using the SQL Server.
I've got everything set up. The IT department has installed the server software on my computer. Within my Access database, I link in tables from a database called "Progress" using a Merant driver. Queries, forms, macros and modules are all pulling from these "linked" tables. Do I need to link these tables into the SQL Server? How do I transistion this database over to SQL? I guess I'm confused about the relationship of how all of this should work.
Right now it looks like this:
PROGRESS ..... linked....... MS Access ....... reporting/results
Where does SQL fit in?

I have an Access database that contains local files and files linked on a SQL server through a DNS connection. I have been using this for years and during that time I have dropped links, added links, changed the DNS server information, etc.
I changed the DNS server information this weekend, deleted all the links, and was ready to start linking the tables with the new DNS information. I click on File >> Get External Data >> Link Tables and am given the traditional file selection dialogue. I go to the bottom (Files of Type) and scroll to the last selection... ODBC Databases().
In the past, after I made that selection, I would then be taken to the ODBC dialogue from my computer to select the connection type and then the actual connection.
Now however, the dialogue immediately stops. It doesn't lock, it just stops and returns me to the Database window from my database as though I wasn't doing anything.
I have reinstalled Office and redone all the updates. Does anyone have any suggestions?
Thanks,
Gary

Is there a way to link MS Access tables with SQL Server tables so the client app sees them as tables from one database?
I have tried linked server but it appears that it gets stale after a while and needs to be re linked from time to time which is not very practical.

Hello,
I have a table called "ShoppingCart" which has fields for CartID, UniqueID and Quantity. At the moment I haven't specifed a primary key for this table becuase none of the fields are unique. I need to be able to link this ShoppingCart table to a table called "Size" using the UniqueID (both tables contain a field for UniqueID) in order to obtain the ProductID and CategoryID of the data item. I then need to link the ProductID and CategoryID I obtained from the first part of the SQL statement to a table called "plants" in order to get information from the following fields in the plants table: Common_Name, Latin_Name and Thumb_URL.
So far I've been able to use an INNER JOIN with the Size table to obtain the ProductID and Category ID using....
SELECT * FROM ShoppingCart INNER JOIN Size ON ShoppingCart.UniqueID = Size.UniqueID WHERE CartID = @CartID ORDER BY ProductID
I now need to be able to use the ProductID and Category ID I've obtained from this part of the query to reference the Common Name, Latin Name etc of the data item from the plants table. Is there any way that I could do this?
I do sometimes wonder if I'm making this whole thing a lot more complicated than it needs to be. At the moment I'm storing details about the different types of plants the garden centre sells in the "plants" table. However, some plants are available in different sizes so I've got a table called "Size" which links to the plants table using the ProductID and CategoryID of data items. The Size table has a unique primary key field called "UniqueID" which is used to uniquely identify every plant that the garden centre sells (this cannot be done using Product/CategoryID becuase different sizes of the same plant have the same ProductID/CategoryID). I'm then storing just the CartID, UniqueID and Quantity in the "ShoppingCart" table. There must be an easier way of structuring the whole thing!
I'd really appreciate any help you can offer me.
Many thanks,
Luke

Hi, I need to link an Access 97 database to sql server 2000. I can't use Enterprise Manager so I have created a simple asp.net page using sp_addlinkedserver and sp_addlinkedsrvlogin.
The mdb file is on a network share, then I have permissions problems: here is a sample
sp_addlinkedserver 'test', 'Access 97', 'Microsoft.Jet.OLEDB.4.0',
'\SVKNFS080Pshareaccess97db1.mdb', 'efco'
sp_addlinkedsrvlogin 'test', false, 'sa', 'Admin', NULL
I have no problems executing these stored procedures (the linked server is added in sysservers table), but when I try to query the access database
SELECT * FROM test...profile
I get this error
Microsoft][ODBC SQL Server Driver][SQL Server][OLE/DB provider returned message:
The Microsoft Jet database engine cannot open the file '\SVKNFS080Pshareaccess97dboutlet.mdb'. It is already opened exclusively by another user, or you need permission to view its data.]
The mdb file is not locked, I think is a permission's problem.
Can anyone help me ?
Thanks in advance

I have a table called ppd2002, which has an id field a testdate field (datetime), and a previoustesdate field (datetime). The testdate field is filled in. I have another table called ppd which has an id field and a testdate field. I need to update the ppd2002 field called previoustestdate with the max(testdate) field from ppd, but that max date must be less than the current testdate in the ppd2002 field. The id field is the link field between the 2 tables. Tried to create a view, then a update but still stuck.

Hi, I have 2 similar databases on the same SQL server (due to licencing and customisation issues for off the shelf software).
I would like to create a third database with site specific lookup tables to map data across to site codes, to do summary queries for data reporting, and to create a single point for data access. I can't modify the 2 databases.
I have created the third database and added the necessary tables, relationships, views, etc. But, how do I link to tables in the other databases on the same server so that I can do joins in a query/view ? I have SQL Server Enterprise manager.
Thanks.
