I have been working on quite a few multi user Access projects in the past few months with a backend and a front end which has linked tables.
I would like to know if there is any way to find out the source of a table linked to the front end and where would its location be on the network.
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 have a frontend and a backend database. As usual i keep the tables in the backend. Now I have some tables which need to be emptied and then refilled. I empty the table using the code
Code:
DoCmd.RunSQL "DELETE * FROM TransNMTbl;"
then I fill in the table using
Code:
DoCmd.RunSQL "INSERT INTO TransNMTbl SELECT * FROM TransTbl;"
The code runs fine. The problem is that the linked table is not used and the sql statement creates another TransNMTbl table in the front end and puts the data there. Bu I need the table to be in backend.
From what I have read, I understand you can't use the seek command on a recordset from a linked table from another database. Is that true? If so, what is the alternative to find a specific record in the table using an indexed field?
View 4 Replies View Relatedhi,
I linked a table (front to back) yesterday. I had a user enter information into this table. It's a login table. The login screen of the asp page is not able to find the record, even though I can see it in both tables. I am not sure what's wrong, since both tables show the same information. Does anybody have any ideas?
thanks in advance.
I have a linked table and want to change it's data source to another table entirely -- ie: different file name.
Can this be done with linked tables, or can you just link to another file with the same name but in another directory? If linked tables have this limitation, how would you accomplish what I'm trying to do. I want to keep the same name for the linked table.
Ultimately, I want to populate a listbox with the different files in a directory and change tblSource to point at the chosen data source.
Thanks,
Randy
I am using MS Access 2007.
I have created a multi-valued field "Product Category" that lookups data items from a linked table. So, the Data Type for the multi-valued field "Product Category" is Number.
Now I want to change the Data Type of "Product Category" from Number to Text, and make a value list that I can type values in and can provide the same data items as the linked table.
How to change item source for the multi-valued field from a linked table to a list that I can type in values? Is there a feature provided by MS Access 2007 can enable such a conversion?

I have a report that is pretty complicated in the page numbering, since it's grouped by Aisle Number (it's a report of hazardous products in a store), and the Aisle Number and the "Page x of x" is in the header.Someone here actually created all of the logic for me last year.how a particular table is being populated with the information.Here's the Event Procedure for the "On Open" event of the report:
Code:
Private Sub Report_Open(Cancel As Integer)
'when the report opens the temporary table needs to be cleared
CurrentDb.Execute ("Delete * From ztblAislePages") 'delete records from table
' the recordset object needs to be opened so it can be used and accessible in the group footer and header sections
Set GrpPages = CurrentDb.OpenRecordset("ztblAislePages", DB_OPEN_TABLE) 'open the ztblAislePages recordset
GrpPages.Index = "Aisle" 'set the index so procedure knows what field to search
[code]....
ztblAislePages is a permanent table that holds temporary information...it's populated with information only for this report, and as you can see from the code above, it's cleared at the beginning of the process.where this information is coming from to populate the table, however.
Code:
Set GrpPages = CurrentDb.OpenRecordset("ztblAislePages",DB_OPEN_TABLE)
The table itself has no source data that I can find, unless I'm not looking in the right place.I've done a search for dependencies and can't find anything.
All I know is that when I choose a store, the table IS being cleared, and it IS being populated with new information.
I just realized that I do not know where my ShellAndWait module is obtaining the constant definitions for the WindowStyle arg. They are all defined presently:
Code:
? vbHide
0
? vbNormalFocus
1
? vbMinimizedFocus
2
? vbMaximizedFocus
3
? vbNormalNoFocus
4
? vbMinimizedNoFocus
6
However, I would sort of like to know where the constants are actually defined that support my ShellAndWait VBA Module. I do not like relying on "osmosis"!
I have split the data base
Added a new table to the back end .But do not know how to update it to the front end
Hi,
I have an Access 2000 database with some linked tables. When upsizing the database I selected 'Save password and user ID with attached tables'.
Therefore in the Linked Table manager after each table in brackets I have the name of the database to which the tables are linked.
I am now wondering if I want to link the tables to a different database how do I change the database name, which is in brackets after the table name.
If I select a table and select 'prompt for a new location each time' I am getting prompted to select a different DSN. At the moment I don't have a DSN and I don't want to have to set one up.
I imagine that the database name and the user id and password I entered in the upsizing wizard are stored in some configuration box but I don't know where I can access this.
Can anyone point me in the right direction??
Thanks
I have searched through a number of threads trying to find a solution to this problem that I am having without luck, so I figured I would post a new thread.
I have an application in access that pulls data from a SQL database. Users can already delete a record out of the database.
The problem comes when I try to give them the ability to update the information in a record.
First, I went to the tables listing and double clicked on the link table that contains my information.
Once that window opens up, I have tried to change a piece of data on this table, but it give me a 'Write Conflict' dialog box stating 'this record has been changed by another user since you started editing it. If you save this record, you will overwrite the changes the other user made.'
This is the same error if a user changes any information on the form and then tries to move to the next record.
What is set up incorrectly that is causing this problem?
I have a linked excel table in my database but sometimes because the network is down I am getting "not responding" message from Access if I accidentlaly try to open the linked table while off-line. That does not seem to timeout at all. I am wondering where I can actually set the timeout so Access will not hang trying to get to the linked source?
View 1 Replies View RelatedI can edit/open existing linked tables (to Sage Line 50, v12) but not create new ones.
Following the procedure:

I can open the Link Table Manager to update previously created links.
Any ideas?

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??

Suppose I have a front end and backend (tables) database which I want to deploye. Currently Access tries to find the backend in the same absolute location (rather than relative position). This causes a problem as drive letters change and sometimes I would want it in a specific location on my computer and another place on deployed computer. Is there anyway to change source of linked tables after compiling to ACCDE
View 3 Replies View RelatedI 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 ...

I have split database (B/E is in the SharePoint library, F/E has users on a local PCs). Sometimes, when I update/add data (does not matter if it is via form or directly in the table) it looks OK, but when I re-open the database, the data are gone.
Problem is that I cannot catch the moment when data were not saved (sometimes data are saved, sometimes not). I can point out this: if I re-enter the missing data, primary key continues subsequently, it looks like the data have never been entered. I tried to use script
Code:
If Me.Dirty Then Me.Dirty = False
on "On Close" form event, does not work.
B/E is linked by VBA code and it looks OK (no error, Link Manager shows correct path). I suspect interrupted connetion to the SharePoint but I don't know how to check it. I implemented VBA script co keep open connection to the SP but the issue persists.
Hi there
I have an application that I run in our business.
Everytime I make changes to the code I have to export all the tables from the original into the latest version of the database with the new code.
This is a pain and makes updates time consumming and prone to error.
Is the soloution to have 2 databases. One with the tables and the other with the code (forms), & reports ect
If so, how do I access tables in the 'tables' database from the 'front end' database??
Thanks in advance

Hi,
as an attempt to improve database performance, I have split a MS Access 2003 database. I have successfully split the database and saved the backend onto the server. My question is, where is the front end. or do I have to create it?
Cheers.

I need help making a front and back end to my database. How should I do it!?!? All I know is what I should put in the front end and what goes in the back end. The rest needs to be explained to me somehow...
