Tables :: Linked Table Disable Password SQL Server
Feb 4, 2015
In Access2010 I have created a linked table to a SQLServerExpress database.I have a user in SQLserverExpress with only reading rights.This linked table is used in a form which only shows the information. When opening the form, it prompts for the SQLserverExpress username and password.How can I configure the linked table so that it logs in automatically with the SQL user I prefer so that the user does not need to enter a user / password?

I have a fe that has 5 tables linked to a backend db on the server.I want to add a new table to the fe that is linked to a second db on the server? What I have tried.I have created the tbl_called in the fe.when I right click on it and go to Linked Table Manager I do not see it on the list. The only tables in the list are the 5 I linked before. Why is tbl_called not showing up??

I have a table that I imported from another database. I used import Access - Link to the table source by creating a linked table. - then downloaded in my database.
I want to use the linked table to create relationships and forms but do not want to even accidently edit it. The table gets updated in the database on a weekly bases and I am hoping it gets updated automatically in my database as well. does it automatically get updated or do i have to set up something?
Also, I want to protect the data in that particular table and either password protect it or make it read only. Can I do that? If so, how?

I am in need of some assistance regarding SQL Server ODBC links and security. This is for a project at work...
1) I have an MDB that has linked tables through ODBC to a SQL Server 2000 database. This is how I chose to write this multi-user application (instead of the ADP method).
2) My IT department created a user ID that the application will use to connect to the database. They chose this method instead of having to create many user accounts with varying permissions. I have programmed permissions within the application.
3) After linking the tables through ODBC, it defaults to my Windows User ID for the connection. Because of this, I have used a connection string with the application's User ID/Password and perform a RefreshLink on all linked table definitions on startup to ensure valid connection.
This is successful, but my IT department is seeing that another user is attempting access to the SQL Server database--the username in the LDB/MDW file! This is what I don't understand. If I open the database without going through workgroup security, the word "Admin" is passed and the authentication fails. If my users would login through the MDW file, their user IDs would be passed and again, authentication will fail as they are not valid users (only the application ID would be valid).
What is really going on here? :confused: How can I prevent the "Microsoft Access User ID" from being passed through the ODBC link?
Here is a sample of the connection string I'm using:
Driver={SQL Server};Server=ServerName;PersistSecurityInfo=Yes; AnsiNPW=No;Database=DBName;Uid=Username;Pwd=Passwo rd;

Hi you geniuses!
I just had to upsize my loved and complex Access database to SQL server 2000 and had to link all tables via ODBC into my client Access database.
I used to use pessimistic locking on all tables when the tables were in an Access database before - worked fine ...
but now my client Access database uses "No Locks" on these tables because they are controlled by SQL server 2000.
Does some genius know how to change this bad behaviour? :confused:

We are sharing an Access 2003 database amongst two departments that contains twelve (12) tables that are SQL Server linked tables. Nine (9) of the tables work just fine for people in both departments. Three (3) of the tables cannot be opened until the user refreshes the link(s) using their ODBC DSN.
We do not understand why nine of the tables work without issue but three will not.
Has anyone ever run into this issue before? Does anyone have any ideas on how to resolve this issue?
Thanks

Hi,
I used ODBC to link the tables from SQL Server to MS Access.
When I link the table, it popup the message:
Select Unique Record Identifier
To ensure the data integrity and to update records, you must choose a field or fields that uniquely each record. Select up to ten fields.
It force me to set up at least 1 field for primary key in a table.
How can I skip it? I do NOT want to setup primary key of the fields in a table.
Please let me know, thanks.

Hi all,
wonder if anyone can assist me with this the SQL Server
security/write (?) issue. The SQL Server Admin has created a table for our Dept. to use and via SQL Server I can get access to it using the username and password she supplied to me. I can also link to this table in Access 2002 via ODBC which is the way I am using to write to SQL server tables. I have developed an Access application to allow one of our staff to be able to write data to the SQL Server table at a click of a button, however when I open the table the 'add new record' button is greyed out, I can not add any data to the table.
I explained this problem to the Admin as well as the way in which we access the table and she is certain that the problem lies in Access but i'm unsure how that can be the case.
Has anyone experienced this problem before ? Is there a fix and if so how is that implemented ?
Should I also post this in the SQL server forum ?
Thanks in advance,
Mitch....

I have an MS Access accdb with linked SQL Server 2012 ODBC tables. I am working on a procedure to copy data from local tables to these linked tables (identical schema). I did a simple
Code:
DoCmd.RunSQL "INSERT INTO linkedTable SELECT * FROM localTable"
This works, but is very slow. Way too slow. (INSERT copies the data one record at a time).
I would like to copy the data in a bulk operation, or operations that I can execute programmatically.

I am rebuilding an application for a client and I have an Access table that I am using as a temporary table. Once the user is done entering information into the temporary table through a form, the user presses an update button that appends the records using an Append Query in Access to an SQL Server Table.
The following error message occurs:
"ODBC -- insert on a linked table 'linked tblname' failed.
[Microsoft][ODBC SQL Server Driver][SQL Server] Explicit value must be specified for identity column in table 'linked tblname' when IDENTITY INSERT is set to ON. (#545)
I am using a form, subform combination to record a bill with many details. The bill summary is posted into a tbl_TransactionsMain table in SQL Server using the ADO AddNew method. The PK for the tbl_TransactionsMain is then entered into the temporary table in Access. When the temporary table records are appended into tbl_TransactionDetail the error message occurs.
What is also interesting is while typing out this post I thought to test the error by manually trying to run the query. The query worked like a charm! :confused: When the orginal error occurred off of the form I tried to run the query manually and it failed. I am guessing that this might have something to do with the ODBC timeout.
I think SQL Server/ODBC connection is not liking how I have a set of records in an Access table with foreign key numbers assigned when I am attempting to append the records. I am new to SQL Server and any ideas are most appreciated! :)

I have a keys table and a keysctivity table. I need keys to not be available if they are currently signed out (return_date is null) or if they have been marked as lost (lost_key = true)
This is my activity table. URL....If for example signin_id 1 was not returned or was lost, key_id 1 should no longer be available. Is this something that can be done?This is the access file I am working on: URL....
create two new tables "lostKeys" "unreturned_keys" and have records moved to their respective tables based on whether they are indicated to be lost or currently not returned.

I have an Access 2010 front end with linked tables via ODBC to a SQL Server back end. Is it possible to add, delete, and otherwise alter the tables on the SQL server from the Access front end? I've tried the following but received an error "cannot execute data definition statements on linked data sources"
DoCmd.RunSQL "alter table [dbo_tblAccountsMvOld] add column [cnt] byte;"
Is there code that will let me do this?

Hi,
I'm using Access 97. I have an Access application that consists of two databases, a front end witht he usual forms, reports, queries etc. and a back end with the data.
I use my own simple logon form to restrict access at the front end, but nothing on the back end.
I really want to restrict access to the back end by placing a password on the database.
How do I still allow people who use the front end to get into the system and access the data, yet prevent them from accessing the back end directly?
I have put the password on the back end easily enough, but when I try to use the front end I just get the message, 'Invalid Password'.
Regards,
Bernard D

I have a table for a multiple parents linked to a child table. I need to figure out a way to only allow 1 parent to be coded as primary, 1 as secondary, and then the rest as other... I thought about making Primary/Secondary/Other a primary key. But then I can only have 1 other. I would have to make a finite number of parents that could be entered and I want an infinite number.... My end goal is to have a report that only has a primary and second parent on it, but the rest of the parents still exist in the table...
*Child_ID
Parent_First_Name
*Primary/Secondary/Other

I have what is probably a stupid question but I've been struggling with this one for a while. I have an ordering database which has an Orders table (containing Order ID, Date, Supplier etc) and an Order Line table within which I have a combo box for Product name, supplier, price, VAT rate, Line price etc. At the moment, I have the order line table as a subform within the Order form (run from the Orders table). The problem I'm having is the subtotal and total fields. At the moment these are in the Order Line table as I cannot figure out how to get these in the Orders table. In summary, can I make a calculated field in one table that calculates values from another table (linked by Order ID)?

Hi,
I created a database in Microsoft Access and then upsized it to SQL Server afterwards.
I now need to add a new column to a table in the database. So I added the new column in SQL Server using ALTER TABLE command. This column is a foreign key which has an associated parent key in another table which contains a description of the column.
e.g.
Main_Table
Case_ID Foreign_Key_Field_ID
1234 78
New_Foreign_Key_Table
Foreign_Key_Field_ID Foreign_Key_Field_Desc
78 Describes the ID 78
I also setup a CONSTRAINTREFERENCE between the fields in these 2 tables.
I then relinked my tables using the Linked Table Manager to pick up the change to the table I altered (Main_Table). I also linked to the new table I created (New_Foreign_Key_Table).
My problem:
In Access if I create a new table I can select the lookup value for a field in the Table Design view Lookup tab. However, I altered my table in SQL Server and then linked to it again to pick up the change. Now when I view the linked table in Access it does not have any lookup value AND it's not possible to change this for a linked table.
Is there some piece of SQL I can use in SQL Server to change the lookup value for the field in my table OR have I approached this the wrong way. Should I have modified the local table in Access and upsized it again?
Otherwise if I select all values from my Main_Table in a form it displays the Foreign_Key_Field_ID instead of the Foreign_Key_Field_Desc because the lookup value has not been set to Foreign_Key_Field_Desc
This posting is a bit long - I hope it makes sense.
Any ideas or suggestions would be greatly appreciated.
Many Thanks

I'm trying to store files on a linked SQL Server table, much the way I would using the Attachment data type in Access. (I couldn't use the Attachment data type, though, due to size restrictions - we're storing about a gig a week.)
Almost everyone says to store the attachments on a file system and save the location - I can't do that because of varying permissions. The files HAVE to be stored in the SQL Server table for security reasons.
So how do I do it? I've tried converting the files to binary and updating the recordset that way, but it always comes back as null. I'm not sure what I'm doing wrong.
Code:
Public Function Test(strFile As String) As Boolean
Dim rsAtts As dao.Recordset
Dim ifilenum As Double
Dim btAR() As Byte
Set db = CurrentDb
[Code] ....

Hi,
My access database's tables are currently linked to an excel document. My question is, how do I move my database to the network? Currently when I move the the database to the network no one can open my tables because the link goes to my documents on my computer which they can't access on the network.
So how do I move the database and maintain the link between the database and my tables?
Thanks in advance,
Ryan Smith

Hi, All,
I have so far only worked with single tables and queries but not with linked tables. Now the following problem has arisen.
We have a database all of whose fields except two are of type = Text. Two fields are type = Memo.
We have to submit this database, i.e. its main table, to an external company for automatic 'cleansing' (UK: Telephone preference service). The cleansing program converts the cleansed database into a comma-delimited text file and returns it to us as such, and we then have to convert it back into an Access table.
(That's the way our supplier works, it is not under our control, and we have to learn to cope with it.)
Now the cleansing program is being screwed up by our Memo fields, because they contain commas. So when the cleansing program sees a comma, it interprets this as the start of a new field, and the same happens when we convert the text file back into a table.
Two solutions were suggested by the cleansing company, but only the following seems suffiently automatic and therefore acceptable to us.
I NEED HELP IN IMPLEMENTING THAT SOLUTION.
-----------------------------
I want to move the two memo columns into a separate table (memo table), linked to the original table (main table). Have the ID column (unique identifier) in both tables to keep the records together. Then I send only the main table for cleansing and the commas in the memo can no longer work havoc.
I have an idea of how to create the memo table: make a copy of the main table and then delete all columns except ID and the two memo columns.
But then I have to link the two tables (I do not know how to do that); where do I start.
I must also ensure that when new records are created (now usually through a form), both tables are expanded. And I must get information from both tables into one form.
At present I do not even know where to start, except for creating the Memo table by copying it and deleting certain columns.
I have a good book (John Viescas: Running MS Access 2000), but it is huge, and the problem is urgent (it stops our tiny company from marketing). I have no time to study the whole book to find what I need in this case. A chapter or page reference would be very useful.
Or some Tutorial on the web that deals with my particular task.
Thanks for your help.
Adrian

Dear All
Since last week I am working on a Database which I will use for my company. To make a long story short, I didn't find any appropiate softwares nor examples on the internet, hence, with my some knowledge in Access, I am trying to make this "to be" useful tool for my self.
Short brief on the project:
This is going to be used for a trading company to register:
- Suppliers
-- Products
- Customers
-- Inquiries
-- Orders
-- Offers
*Relations:
- Suppliers can have one or many products
- Customers can have one or many Orders / Inquiries / Offers
Problems:
(I have tried many different ways, but going nowhere)
1) The "Customers" table have 3 tables (Orders/Inquiries/Offers) linked to it - and all are based on the primary key "CustomerId". --> How can I make a form to enter these data linked?
2) Under "Orders" I want to select supplier from the Supplier table and Product from the Product table -- How?
I know this is a lot of info and probably too vague, but if someone could assist me with a few problems - then I would really really appreciate it and compensate somehow.
Looking forward for your help.
Best regards

I am looking to copy one exceptionally large table to another. I can use VBA to copy the entire Report2013.accdb to Report.accdb while compacting at the same time. This is very fast and works well. However once it's copied I need to rename the table tblReport2013 to tblReport. None of these table are in the accdb that I am running the scripts from FrontEnd.accdb. I am working very hard to keep the data tables under the 2 GB limit, which is why linking and keeping the data separate is necessary. There is the chance that Report2013 will be on the network while tblReport will be local to the user, and may or may not be a subset of the Report2013.
I have considered a number of options:
DoCmd.Rename - I can't seem to tell it a database location
I could try
docmd.copyobject - and see if it keeps the file size the same or smaller then the original.
I could just write the sql statement and copy the data that way, and compact the table afterwards. The trouble with doing the transfer that way is hitting the 2GB limit, before I can compact/compress the newly imported data.It just seems odd to have to find another solution when all I really want to to rename a table and ensure the new new is still linked as a separate table.
