Linking A Table
Nov 10, 2005
Little puzzle this.
I need to link from SQL2000 to Access to get to a table held within an
Access DB. Now you can link within Access to a SQL table, but can this
be done the other way round ? It's the first time I've needed to do
something like this.
What I have is an application which was written (by me) with an Access
backend (to run on a CD) and now it needs to run on SQL. However, I
want to be able to swap over between backends so that I can choose
where this runs from. I've done this with the sole exception of one
table. Previously most of the data was held in one MDB file and a link
to another (one local copy and one on CD). My queries use the link to
query both local and the CD copy data together.
I can re-write things if I need to, but I was curious about there being
a way of doing this. What I want in effect is to query a view on SQL,
but the data will be held in Access instead of on SQL.
I suppose I can import as I need it as the data is purely read only. I
don't think this can be done, but wanted to check first. I can always
move the remainder of the data over to SQL if needed. It's not a big
problem, just something I'm curious about.
Any pointers would be appreciated.
Thanks in advance
Ryan
p.s. In case anyone wonders why I have taken this approach it is
because we have a query tool and data that we send out to clients on
CD. Some now want this web based, so I will publish the application on
a Citrix server, and by changing a config file can swap within the
application to point to SQL (by changing the ODBC settings). This way,
I only need one copy of the application and can change backends as I
need to.

Can someone help me with how I should set the relationship in my address tables and how they will affect the deleting of a client?
So, if I have:
tblClients ClientID
tblClientAddresses AddressID
tblClientAddressLinks AddressID, ClientID
Currently I have them set as a 1-M from tblClients to tblClientAddressLinks and a 1-M from tblClientAddresses to tblClientAddressLinks
If I try and delete a client and there address is shared wont this go very wrong?
So here is what happens when I try and delete a client:
The DELETE statement conflicted with the REFERENCE constraint "FK_tblClientAddressLinks_tblClients". The conflict occurred in database "DBSQL2", table "dbo.tblcLIENTAddressLinks", column 'clientID'.The statement has been terminated.
Here is what happens when I try and delete an address:
The DELETE statement conflicted with the REFERENCE constraint "FK_tblClientAddressLinks_tblClientAddresses". The conflict occurred in database "DBSQL2", table "dbo.tblClientAddressLinks", column 'Address_ID'.The statement has been terminated.

I am trying to link a table from a MS SQL database into access97 thru ODBC. When I do this, I get the message "Can't define field more than once." When I look at the table in SQL, there are no duplicate field names, however, when I bring the table in to do a Crystal Report, I see there are 2 fields that have duplicate field names 6 times. (Evidently Crystal doesn't care about this as Access does.) Any clues on what is happening?

I would like to hear your thoughts on a philosophy I adhere to.
As a rule of thumb I've always preached that Unique Indexes are for linking tables and Primary Keys are used to ensure that records aren't duplicated. I’ve embraced this philosophy for a couple reasons, the main one being that I don’t have to create numerous foreign key fields in the foreign key table.
However I’ve done most of my programming in Access and am now in need of something more robust (SQL Server v7) and I’m wondering if I need to reconsider.
I do also have a how to question; that being is it possible to create a table join on a unique index in SQL Server v7 and if so how? I would like to have an Auto Number / Auto Incremented / Unique Identifier field in the Primary Key table that links to a numeric field in the Foreign Key table.
Thanks in advance

Rather than using the upsize wizard in MS Access to connect to tables on a backend SQL server, how would I go about linking an Access Database to an existing table on an SQL server?
Thanks, Phil

I would like to create a MSAccess97 front end for some SQL7 data.
I created an odbc source system dsn for the server holding the SQL7 data.
When I try to add a table to my Access97 database by linking it to a SQL7 table, the only choices presented me are tables in the default database for SQL7 on my server. How do I link to tables in another database on that server? Thanks.

I`m trying out SQLServer7, have installed it on my workstation, have been able to open access97 and link to sql7 tables I created. Want another user to use access97 to set up her own database and link to my sql7 tables. Do I need to install anything from the sql7 beta disk on her desktop? Right now she can`t link a sql7 table to her access97 db. Thanks.

Hi,
Something strange has happened to my table. I used Enterprise Manager today to delete 3 columns. When I went to re-link the table using Access Linked Table Manager, it gave me an error. I then deleted the link to the table, and tried to Link it again using 'Get External Data---Link Tables'. I am getting an error (no surprise!):
" 'dbo.tblSpaceUse.PK_RoomID' is not a valid name. Make sure that it does not include invalid characters or punctuation and that it is not too long".
When I go into Enterprise Manager to 'manage Indexes' on the table, it shows me that the existing index is in fact dbo.tblSpaceUse.PK_RoomID.
About a month ago, I had to rename the index, because it had been pointing to the wrong table. The SQL I used to rename it (in Query Analyzer) is:
EXEC sp_rename 'dbo.tblSpaceUse.PK_RoomID', 'tblSpaceUse.PK_RoomID', 'INDEX'
I have been using the table successfully since then, until today. I have not done anything with the index; the only change I attempted was to delete 3 columns (not related to the index). I do not think I have made any changes to the table since I renamed the index.
I tried to run the rename SQL again (a desperate attempt!) and get the error message:
Server: Msg 15248, Level 11, State 1, Procedure sp_rename, Line 192
Either the parameter @objname is ambiguous or the claimed @objtype (INDEX) is wrong.
Any ideas on what went wrong and what I can do to fix it???
Thanks,
Lori

I have a table 'Group2Operation' that stores many to many relationsbetween the 'Group' table and the 'Operation' table (each group is haspermission to perform one or more of the available operations)PROBLEM=======I need to prevent duplicate entries being created. e.g. lets say thatin the 'Group2Operation' table a record links the 'editor' group tothe 'publish' operation. Should I prevent an administrator creating aduplicate of that record? (Otherwise deleting that permission willhave to be done twice or more for it to be effective)SOLUTION?=========So far I've done this with a trigger:CREATE TRIGGER Group2OperationDuplicates ON dbo.Group2OperationFOR INSERT, UPDATEAS UPDATE Group2OperationSET NoDuplicate = CONVERT(nvarchar(10),GroupID) + OperationTagThe 'NoDuplicate' unique index column in the Group2Operation tablestores a concatenation of the unique group and operation identifiers.So when an attempt is made to create a record, the trigger is fired.If there is a duplicate, this will mean a duplicate entry in the'NoDuplicate' column. As a result, the INSERT or UPDATE will fail andthe duplication will be prevented.WHAT DO YOU THINK?==================What do you think? Am I going about this in the right way? Is atrigger a good way to do this or should I rely on application logic toprevent duplicates?Any help appreciated by this db novice.John Grist

I have an assignment where I am to create two tables within a database. One of the tables have the name ContactPerson with the attributes; ID, Forename, Surname, Email, PhoneNumber. The other table is called Company and has the attributes: ID, CompanyName.
Now my problem is that I have to link a ContactPerson to a specific company, but I can't have them in the same table.
I understand that I can use the join statement to show both tables in one query but I need the database to know which person is linked to which company when I implement this databse into my asp.net project.
How do I do this?

I am modelling two fact tables of Actuals and Budget which are at different granularity, Actuals are at day, customer and product sub category level. Budgets are at month, Region and Product category level.
Month, Region and Product Category is present in Date, Region and Product Category dimension respectively. I have only three dimensions as Customer, Product and Date. Linking those dimensions to Actual Fact table is not an issue, what is the best way and options are there to link budget fact table to those three dimensions.

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)

I'm writing my first web site using VS 2005 and with my login page I'm trying to link with my SQL database using the following setting in my web.config file
<appSettings> <add key="SQLDB" value="server=STEVE-LT; database=MasterDB; uid=sa pwd="/></appSettings>
Then in my Login.aspx file I use the following code to access the SQL database
Dim Sc As SqlConnection = New SqlConnection(System.Configuration.ConfigurationManager.AppSettings("SQLDB"))Dim SqlCmd As SqlCommand = New SqlCommand("Select Password, Name from Login")SqlCmd.CommandType = CommandType.StoredProcedure
Sc.Open()SqlCmd.Connection = Sc
This raises the following error message
A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)
Could someone please tell me where I am going wrong. Thanks

I can't seem to link a 6.5 database from 7.0 and there's nothing in help which seems to help. Is it a "SQL Server" or do you have to use the OLE DB Provider? If the latter, what's supposed to be in the Product, Data Source, Provider String and Catalog fields? What about security? I've tried everything I can think of and can't get it to work. I also get errors creating a new DTS package that says "Could ot create Component Categories Manager", and then "Error during creation of DTS Package". I installed the desktop version of 7 on an NT Workstation. Has anyone successfully linked a 6.5 server in this environment?

I am not a database manager, but I work with people that use databases for sales and customer service... so I am not too familiar with the code and lingo... please bear with me.
We use two databases - one is in SQL, and it is for pre-sales customer service... i.e. tracking notes, phone calls, emails, and opportunities.
The second database is in Progress, and it is for actual quotes, tracking time, labor, materials, cost, and revenue.
As of now, our sales people have to enter new customers in the SQL database, and then duplicate the information in the Progress database. It's very frustrating, because everything needs to be entered twice - name, address, phone, shipping info, etc. etc. etc... When we first started this - 10 years ago - we were told that it could all be linked.
So my question is - is it possible to link these databases together? When our sales people enter a new contact in CRM, I'd like it to be automatically entered into the Progress database. If they make a change to a phone number, I'd like that to be updated in the Progress database. Also the other way around - if a shipping address is changed in the Progress database, I'd like it updated automatically in the SQL database.
Please tell me this is possible - and easy!!! Thanks for any help you can provide at all.

I would like to use MVJ's formula for creating a date table.
I would like to use it with our main ERP database. However, I am reluctant to make changes to it because I fear that at some point when we upgrade that software and it's database that the upgrade program will delete my table.
So, here is my question. Performance wise, does it matter whether I add the date table to our ERP database or if I create another database (on the same server) for the custom date table? Does linking between databases take substantially longer than linking within the same database?
