General :: Split Database - Inconsistent Number Of Records
Nov 8, 2012
I have split the database, with the back-end residing on the server. Only 1 other person is working in Access right now; she's verifying the data. Today she's working directly in the back-end, could this be the problem. If it is, I'm going to have to create a front-end for her quickly.
My problem is this...I'm working on queries and forms so that the scientists who will ultimately be using this application, won't be able to go in and inadvertently change something in the tables set-up. When I'm in the back-end main data table, it says I have 2723 records.
When I create a front-end query to query all the records in that table, it says I have 2160 records.
The input form that I created with most of the same fields as the query (created BEFORE I created the query...I'll have it pull from the query now instead of directly from the table) also says we only have 2160 records.

I've got a database in Access 2007 that keeps track of client data for work. It's been working fine for about a month, and suddenly today other users can't change any information because the records are suddenly locked when accessed from their accounts.
I've already checked that they can't update forms, tables, nothing.
I've checked the database properties, it defaults to shared with no locks.
I've checked the properties of my forms - no locks.
I've double checked the permissions to the folder that the database is in - no restrictions.
The database is split.

We have a database that is split. Every user has their own front end (installed via a .bat file so that the users always have a local copy of the most recent version), linked to a shared back end on a server. This seems stable and functional for us so far.
However, because our users are geographically separated, I don't actually know how many folks are using the database. I know the folks who contact me, but everyone in our company could use it if they wanted to.
For requesting funding, guiding future development, etc., I need to get some metrics:
Total number of unique users
Avg uses per day
Total number of simultaneous users (daily, weekly, and monthly maxes and mins)
What is the best way to get this info? Write user info and a timestamp to a table each time a front end is launched? Are there tools for monitoring this sort of information?

I haven't done any testing yet on splitting the database I'm working on but a question came up today about networking.
This database is going to be used by a few equipment operators to record machine readings on the manufacturing floor. There is a wireless network and we are in the process of confirming that the wireless signal reaches all the areas. The users will be using ruggedized windows tablets to enter the data.
The BE of the split database will reside on a network drive to ensure everyone that needs it will have access and it will be regularly backed up. etc.
Since there is alot of heavy machinery, there may be some spots where connectivity will be weak or non-existent while they are entering their readings.
The question is how will the runtime FE handle it if connectivity is temporarily interrupted?

I tried saving my split database to a flash drive so I could move it to a computer that is connected to the shared server but it did not go as I planned. The back end with the tables works fine, but when I try to open the Form on the front end it says it cannot be located. I just want to take all the files I have (Should only be 2 front/back ends) and move them onto a new computer.

I have a split database with the back end on a sharedrive. I have the front end saved on my own drive and the same for my colleague.
When I view the front end version of my colleagues, I can see a records on there that she has input but I can't see them when I open my own copy of the front end plus when I view the back end I can't see the records there at all.

I am attempting to split an Access 2007 database. My company has two locations. From my location we are remote connecting into the server. While down there they are connecting directly. When I split the database, people in my location can use it fine. When people down there use it, they get a not valid path error.
This is because the network drives are mapped differently. I have been reading that the solution is to use the UNC for the back end file path.

I am currently working on an application where I am using MS access as my FE and working with linked tables to SQL server BE. I also have a few temp tables within Access that are not linked but needed.
1. What are my steps into making this into a SPLIT DB? I am assume the BE will have my linked tables from SQL and the FE will have my temp tables and forms. Is this correct?
2. Once I split it, then I can make an .ACCDE file for a Mulit User environment, is this correct?
What other steps should I be made aware of?

I am trying to use VBA to backup the BACK-END of a split database (so I can automatically archive selected data). If I use FileCopy I get a message that the BACK-END database has not been found.Obviously I could 'unlink' the BACK-END, copy it and 're-link' it..Is it possible to copy the BACK-END tables(not just the links) into the FRONT-END and get at them that way?

My database was working fine until I split the database and now I'm having issues with this function:
Code:
Public Function OpenFirstAttachmentAsTempFile(ByRef rstCurrent As DAO.Recordset, ByVal strFieldName As String) As String
Dim rstChild As DAO.Recordset2
Dim fldAttach As DAO.Field2
Dim strFilePath As String
Dim strTempDir As String
[Code] ....
It's getting stuck on the "strFilePath = strTempDir & rstChild.Fields("FileName").Value" line. The debugger says that there is no reord. The strTempDir is correct. I am assuming that the issue has to with linking to the database.

I have a simple select query on a SQL table from Access. The query is:
SELECT tbl_Orders.OrderID, tbl_Orders.Approved
FROM tbl_Orders
WHERE (((tbl_Orders.Approved)=0) AND ((tbl_Orders.Completed)<>0))
ORDER BY tbl_Orders.OrderID;
The strange thing is that sometimes it pulls 34 results, and sometimes 38. From what I can tell, it should be pulling all 38.
What can I do to make sure it gets all the records?

I have a split database with the backend on our server. When I go to my server and look at all the open files on the network everyone who is in the backend shows up twice. One has zero locks and the other has multiple locks.

I've just split a database into the front-end and back end components. But how to distribute it further.
Additionally, I need people who have the front end to access the database from their homes, not just from work.
What would I need to use?
Is there anything available for free?

I have a split database consisting of an ACCDB backend helf on a shared drive, and a local ACCDR frontend distributed through email. I recently distributed a copy of the ACCDR to a user, and she says that the main menu opens fine, but when she clicks a button to open a form, the form opens but is completely blank. I've googled some possible causes for this (e.g. on Allen Brown's website) and none seem to be relevant, or would explain why this started happening all of a sudden. I can't reproduce this bug at all.

I have a split database. I have secured the mde sufficiently but I need to secure the back end so that no one could link to tables in it. If I introduce a password to the back end is this going to require those using front end to supply the password? If not then this could be good solution.
As the database is on the network drive, is there any other way to prevent people to link to the db? Can I hide the db in the network drive? Or should I hide tables in the BE. Should these still be available to be linked?

I'm having a problem with a database that i had split. While creating teh database, i had it stored on my personal drive at work, but wanted to move it to the shared drive so the data could be stored there. this is to deal with cross site network connectivity issues that we encountered with another database here at work.
When splitting the database, i split it on my personal drive and then dragged the back end to the common drive. I realized my error, but when attempting to correct it, i somehow have two of the same file, and no back end?
I receive the error on the attached document when attempting to access any of the tables or information in either of the files, the "back end" that i placed on teh drive, and the "front end" that i have on my personal drive.
I also tried to relink the tables through the linked table manager, but receive the same error when attempting that.
Is there a way to recover from this? I had backed up my file by making a copy prior to splitting, but somewhere in this process, this became linked to these and is having the same issue. Is there a way to recover the old "unsplit" version? I cannot copy over all of teh tables, etc. because i get the same error as earlier.
I can attach a copy of my database for reference...

I have a split database made in Access 2007. Each user gets their own copy of the frontend from a script. I wanted to be able to edit the design view of the backend tables even if people were using the database so I made all the forms use snapshot source and only allowed data updates through VBA macro update queries. Having any form open locks the backend source table from being edited. In fact, I've found that just having a normal snapshot query open causes the message "Either an object bound to table 'whatever' is open or another user has the table open. Do you want to open the table as read-only?"
Is there some way to have a table be the source for a form or query, but still have it designable under most circumstances?
Attempted to late-bind a recordset on form load; result was the same:
Code:
Set rs = CurrentDb.OpenRecordset("Select redacted as ft from tblRedacted ", dbOpenSnapshot, dbReadOnly)
Set Me.Recordset = rs
Set rs = Nothing

So a while back I created a database which I use to keep track of my companies large list of products. It is very simple only 3 tables, 1 query and 1 form. After running into a problem with copying and pasting updates on each computer in the office I decided to split the database on a network drive. This worked for a bit, however I had to add new fields and modify the form, which corrupted the file. Luckily I had a backup before the split.
As far as I could tell all I had to do was modify the backend file and make a new front end. However it seems like it is not as easy as I thought it would be. How do you modify a split database without corrupting the files or using a non-split copy?
