Linked Databases
Sep 21, 2004
Hi
I have an access database which is linked to several tables in other SQL databases. I have made a list box displaying a single field from one of the linked tables. I have the list set to multiselect simple. After I've made a selection and then go to close the form I get this error message.
ODBC - Insert on a linked table 'dbo_Name" failed.
I dont want to change any data in this table. I only want to read and extract it to another table. How can I stop access from wanting to update the table.
OK I've thought about it some more, can I as part of the on click commands for the close button, clear any selections from the list prior to closing the form. That way there are no fields selected to be changed and no error message. If I can any pointers on how?

I have a database with a number of linked tables that are linked to tables in different databases (not a back-end).for example, I have table1 that is linked to table1 in K:databasedb1.mdb.table2 linked to table2 in S:datadata.mdb.and so on...
However, recently we have moved all our databases to a new location.
K:databasedb1.mdb is now residing in O:masterdatabase
and S:datadata.mdb is now residing in O:masterdata
and so on...
I'm now in charge of relinking all those tables to point to the new location.I would do this in linked table manager one by one but we have 100s of tables linked to multiple different databases in different location.is there a way to create a VBA code that will automatically do this re-linking process?
so,
1. find unlinkable tables
2. search its new location under O:master
3. re-link it to the new location
Database names and tables names have not been changed. Just the location of databases.

I am currently working on a database which has links to two other databases both of which are password protected. The problem occurs when the main database needs to access data in the others as it prompts for their passwords to be entered.
I was wondering if anyone knew a way to automate this so that the user would not be asked for the password but instead it would be coded into the main database.
Any help would be appreciated.

I have a db that runs call stats (Master) this exports to several Department (Slave) Databses. The Slave db's can be accessed by any of number of Managers.
My problems (Amongst others!) is that I run the master every 15 mins and the slaves are linked to the master tables. How can I set this up so that these slaves can be updated whilst they are logged into?

there are many threads about Table Linking but i coud not find one that answers my specific questions.
1. Can i either prevent database from linking to my tables? (or give permissins )
2. If not, can i make the table read only when linking?
3. Is there a way to confirm what databases are linked to my tables?

I am trying to build a Form that will show an estimate (then eventually will be moved to a project if customer and employee aggree to price and project) in a Form F_Estimates is a M_Customers(Customer_ID) (Based on a Table) and thier info in a Subform. Also is the "projected costs" from parts out of the Parts(Part_ID) (Based on another Table) in a second Subform as a list that I need to calculate $$$ in
(Dang that still sounds evil and definately NOT understandable even after edit... so)
Here's some basic info
Tables
EstimatesandParts - Table
EstimatesandParts_ID : Autonumber
Estimate_ID : Number
Part_ID : Number
Parts - Table
Part_ID : Autonumber
PartNumber : Text (not a number due to some part#s have letters in them)
PartName : Text
Unit Price : Currency
Description : Text
Estimates - Table
Estimate_ID : Autonumber
InvoiceNumber : Text (again can have letters in it)
EstimateDate : Date/Time
EstimateTime : Date/Time
Employee_ID : Number
Customer_ID : Number
ProblemDescription : Memo
Customers - Table
Customer_ID : Autonumber
FirstName : Text
LastName : Text
CompanyName : Text
Address : Text
City : Text
Province_State : Text
Postal_ZIPCode : Text (CDN Postal codes are letter num letter...)
you can see the link table in the EstimatesandParts Table
Now I want to use that link to populate a subform in the F_Estimates form
Forms
SF_Customers - SubForm
(all boxes atm are text boxes on this form till I figure out the Parts section then will use same base for this so I can pick any customer in the database to be the customer for this estimate. Also will have ctrl button for making new customer with customer form and a refresh on Focus Gain bit of code)
FirstName
LastName
CompanyName
Address
City
Province_State
Postal_ZIPCode
SF_Parts - SubForm
Default View -Continuous Forms
(want it to be a list of parts that I can grab prices and descriptions from then in a bit of code to calculate a cost of parts)
Part_ID : Combo Box
Control Source - Part_ID
Row Source Type - Table/Query
Row Source - SELECT Parts.Part_ID, Parts.PartNumber, Parts.PartName, Parts.UnitPrice, Parts.Description FROM Parts ORDER BY Parts.Description;
(Pulls info from the table Parts for input into a list of parts to be used on that project)
PartName : Text Box
UnitPrice : Text Box
(here's where I run into problems due to the fact that the form is not based on the parts table but rather the link table EstimatesandParts so I can't propogate the info to the 2 other text boxes, ps I dont care if they cant be text boxes and have to be linked or some other type I'm not "set" just need to find out how to make it work )
(have tried a couple things to complete this task)
Me.txtPartName = Me.Part_ID.Column(2)
Me.txtUnitPrice = Me.Part_ID.Column(3)
(works AWSOME ... for ONE ROW then propogates the second selection to the first and second and third selection to first second and third and so on ...)
(tried to make control source for the txtPartName to)
=Forms!Parts!Partname
(Doesnt exist .. akkk, cant use ActiveForm either as it doesn't focus on the SubForm but the MainForm ... cry)
F_Estimates - Form
Estimate_ID
InvioceNumber
EstimateDate
EstimateTime
ProblemDescription
(all basic Text Boxes)
Employee_ID
Customer_ID
(Combo Boxes Select Customer and Employee from list of present ones of each)
SF_Customers
SF_Parts
(Both SubForms on the main form)
Now this is an Exerp from my entire Database I like to work on one small problem at a time and I have made this its own little database till I figure out the problem then I will bring the info I learn back into the rest of the database and go from there ...
Hope you can help I have a feeling I will need to make a recordset and go from there but I'm just not able to wrap my head around that for some reason
Thanks in advance for ANY and ALL help that I get from here

I'm creating a database that keeps track of printing jobs at a printing company... I started my project by drawing out how I want the databases to be configured.
I was going through a book that was made for access 2000, but I need to create this in access 97 because that's what the company has on their computers. One of the features in Access 2000 thats not in 97 is subdatasheets...
Basically, what I want to do is for each printing job, there can be a bunch of different tasks that need to be completed and billed for. For example, on one printing job, they need to design a logo, and then they need to print it out and send samples across the globe, and then they need to create a pdf, etc. This is going to be different for each job.
What I figured I would do is create a separate table to take care of all of the different tasks that are related to each job. This table would have the primary key of the job from the main table for each individual job, and then they would be related in a one (MAIN entry) to many (tasks) relationship.
Is this correct in how I want to do that? How will I do this inside a form, I want them to enter the information in table that expands as they put more tasks in?
This might be a very simple question, I just want to know if I'm going in the right direction.
Thanks much!

Hello,
I have been reading a lot about splitting databases on this forum. I still have some questions.
1) Will the FE (Front End) still show the tables?
2) Will users still be able to edit the forms, reports, etc.?
3) Will my code be hidden
4) Will all the users have up to date data showing when they open the Database?
5) Can more than one person open and input data in the database at the same time?
I also want to make an MDE copy, do I split first or make the MDE and then split?
The whole point is the following: I want the people (maximum 10) that will be using this database to only be able to do enter and view data. They should be able to generate the reports but not create new reports. I only want ONE person to be able to edit the forms, code, and reports. How would I do this.
Your help is much appreciated

Forgive me if this is in the wrong forum, so MODS, do what you will.
I'll come out and admit it right now, I'm a newbie here and have just started using Access2003. I'm in a city government so I need other users to be able to view and access my database, BUT I don't want them to be able to edit or change things. I want to be the Owner/Administrator of the database and no one else. I want to be the only person that can make changes.
Is this possible in Access 2003? Can other users only open it in Read-Only format but when I open it, it's editable?
Any info would be greatly appreciated. TIA!

Hi,
I have an MS Access database on a server which acts as a back end, with about 30 users using the data. They each have a copy of the MS Access front end located on their PC's.
Every time I make a change to the front end, I have to redistribute the new version to each PC.
What I am wanting to do is put a single copy of the front end on the server, and adding a shortcut to this front end on everyone's PC's. This would allow me to make changes to the front end without having to redistribute to all users.
What I was wondering is, if I put a single copy of the Front end on the server and simply shortcut to that front end, will it cause any problems, or are there any issues that I should look out for?
Any help or advice much appreciated!

Just trying to get some more replies...
This post is really aimed at someone that has experience of network databases and the problems they can pose but if you can help at all that would be great!
I work for an insurance company and we have created a database for registering complaints on. The one we currently use is a single .mdb file which can be shared by up to 60 people at any one time. This is creating a lot of problems when the queries and some VBA code are run. I therefore made a server file which is just an mdb file with data tables in and NO forms or queries. This file is stored on a shared drive on the network server. We then created a client file which contains all of the forms and queries and code. This file contains linked tables to the server so when data is entered into the form, it "Sends" it to the server mdb file. The client is installed on each of the local machines c:. The problem with this was that if we made a change to the database, we would need to reinstall the client on every single user pc. This would of took ages. I therefore made an auto-update function that checked the version number on the server and if the server number was greater than the client number, a simple .bat fiile was run which copied the updated client file from the network to the relevant users local disk.
The problem we have now is that our IT department are concered that if we make a change to the client and all the staff log in at 9am for example, it will start doing multiple copying of a file around 8mb in size to around 60 machines. They are only running on a 2meg pipe so this could cause some problems. We are not looking to change the client & server idea but does anyone know if this will have a big impact and infact if the updates for 60 machine is the equivalent or lesser of 60 people sharing the single file i mentioned earlier. If the IT dept are happy with 60 users accessing the same file at the same time, which they currently are, why are they unhappy with it updating these machine using the new method.
Would really apopreciate any thoughts anyone has..
Thanks a lot.

The problem is that i have two copies of this database with different records (with ID starting from 1 to each one) and i want to merge the databases into one.
Any ideas how to do this without lose the connection of the records?
Thank you in advance.

Hi,
How do I merge these two datbases? I have downloaded them from Microsoft online templates, here
http://office.microsoft.com/en-gb/templates/TC010178391033.aspx?CategoryID=CT101426031033&av=ZAC000
and here
http://office.microsoft.com/en-gb/templates/TC010185481033.aspx?CategoryID=CT101426031033&av=ZAC000
and I want to have the two databases as one so that there will be a fourth tab on the cintact management database with the order form on? I want to be able to link the two so I can have all the customers details and orders together and print off reports. I really have not dealt with Access before so I really dont have a clue. Any help would be truly appreciated. I am sure it is easy but I just cant work out how to do it.
Thanks very much
Danny :)

Hello-
We are using an Access database for off-site data entry. We therefore have one master database we keep in the office and then a "template" version -which is identical to the master version except no records - we bring to each site, do the data entry and then merge that data back into the Master database.
Can anyone help suggest ways to make the data merging process more efficient. The database has approx 12 tables, so I dont' want to create an append query for each one every time. Is there a way to just "merge" two identical databases??
THANKS

Hi all:
Would appreciate any help that anyone can offer. Have a client with an Access2K database that gives the dreaded "...No read permissions on table MSysObjects..." error. I'm trying to just get the data into a new clean mdb but Access blocks me at every turn.
Have tried compact & Repair
Have tried JetComp
Have tried TransferDatabase via code
No luck, can't get at the data.
Now here's the kicker, the database is the back end to a VB6 application. The application continues to run fine and is happily accessing and updating the database. Any suggestions about alternate ways to get the data into a new clean mdb would be much appreciated.
TIA
John

I have 2 different databases. One for Archives and one for active claims. Both databases have identical tables. I'd like to create a query that will pull information from both databases. I'm pretty sure that I can do this with a union query, but I'm a complete noob with sql.
Can someone give me an example of the sql code to use to pull information from tables on both databases?

Hey all!
Okay, so here's a real puzzle, so put on yur thinking caps!
I have two large databases that are twins of eachother, with only a minor difference in a small corner of one table. Even the forms are exactly the same.
I want to split each one from thier tables, so I have databases strictly for [tables], and strictly [forms, queries and reports]...
Then I would like to get rid of one of the copy cat [forms, queries and reports] db's leaving a single [f,q and rpts] db with the ability of ANY user (not a semi-skilled db dev such as me) to have the option at opening, which db to link to for the tables (without going into the tool bar, since it is not visible to them).
Is there an EASY way for a "non-dev" user to choose which [tables db] on an opening form/switchboard?
Live long....prosper.
