Corrupt Backend
Mar 21, 2005
I have a database with backend tables. I came back to work today and somehow the main table in the backend has been corrupted. I tried to repair the table in the Backend and I get the following error Could not find field 'Description'..
Now when I try and open the Backend I get this error. The database 's:SOE_CONTROLSoeControlDatabaseBackend
ew_1-8T_SOE_DATABASE_be.mdb' needs to be repaired or isn't a database file.
You or another user may have unexpectedly quit Microsoft Access while a Microsoft Access database was open. Do you want Microsfot Access to attempt to repair the database?
When I click yes I also get [B]Could not find field 'Description'.[/]
Each time I have done this another DB1 or DB2 or DB3 or DB4 table has been created. When I look in the tables I can see that somehow there is a deleted record and it will not let me delete that record. I delete it and then open the table again and the same deleted record is still there.
I hope this is making sense because I sure need help!!
Thanks!

Hi, I have a networked DB and I can't update the FE because the LDB file is locked. It says there are about 8 users in the DB which I know isn't true (I keep a table of current users and I prevented any new people from logging on before I went home last night)
I've never had this happen before? Does anyone know how I can fix it and kill the connections/Delete the .ldb?
I'm sure I caused the problem cause I've just put a few weeks development into the live system but i'm not sure why. I know if I have left recordsets open this can keep the connection but are there other reasons why this may be happening?
Thanks, Tom

Hi,
I have a question.
I know that mdb file maybe corrupt sometimes, but I want to know what conditions will make it corrupt?
And also, if we create adp file as frontend, and SQL Server as backend, can we mimimize the corrupt condition?
Please let me know about it, thanks.
Because I don't want to happen corrupt.
Thanks.

I'm getting the following message when trying to open a database and the db will not open:
Record(s) cannot be read; no permission on 'MSysAccessObjects'
All other databases on the network open fine. I can't run compact repair on the said db nor can I link to it.
Any pointers would be good.

My client is reporting corrupt characters cropping up in fields. These characters appear as Asian Characters. They only corrupt one record.
This happens very seldom. In fact, it hasn't happend for about 2 months and today it happend again. Their was no change to the database.
Is this a network problem? Network noise corrupting data?
Thanks

Hi there,
I have recently converted an Access 97 database to Access 2003 and have noticed some records have been replaced with oriental symbols. I've noticed about 2 new corrupt records a month since it was converted. Does anyone know why this is happening and if the corrupt records can be recovered?
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

Hello All,
Let me start by saying that I do not claim to be an expert database developer. I own a small company. I'm good with Access, but from time to time, it gets the best of me.
I've been reading alot of the posts so please forgive me if this topic has been covered. I couldn't find a thread to help me with my problem.
I have a table called 'projects'. This table has an autonumber field (you know where this is going, huh?) that serves as the primary key for the table. I realize that this is a big no-no now. Please go easy on me... :-)
I have a form, also called 'projects'. This form has a comboBox that uses fields from the 'projects' table as its rowSource. The user (myself) selects a record from the comboBox and the afterUpdate finds the record in the table and bookmarks it. The corresponding fields on the form update. We all know the drill.
I'm calling any record entered prior to today, an 'old' record...
... anything from today is a 'new' record.
So now I can still pull up 'old' records, but not 'new' records. Even if I close the form and try to add it directly into the table, it's like access doesn't recognize it. It'll let me enter it, but I cannot pull it up via the comboBox.
My first instinct was to just copy the table (structure & data) into a new one and see if the problem goes away. Two things... the problem does not go away and it renumbers my primaray key and so even if the problem did go away it would give all of the related records in other tables new parents, leaving a few orphans. so much for no child left behind...
anyway, i tried copying the structure only into a new table. I manually added a record. I was able to pull it up using the form. I copied the 'old' records from the old table to the new table. I can pull up those... but now I can't pull up the record I entered manually. I imagine that I copied the corruption into the new table.
It's almost like that the table is corrupt in that it will not index new records properly. I'm not referring to my own indexing, I'm referring to something that I suspect microsoft has on the backside.
Can anybody help me?... :-)

Hello
I have a table within my large database application (one of the main tables) and some of the records keep doing strange things, characters such as: '佀渀攀 䌀愀氀氀 㐀 䌀愀爀 䌀愀' keep appearing and it splits the fields and mixes them all up. I presume they are corrupt records. Without having to create a new table and importing all the data in to a new table (there is a lot of data and this application is used throughout the normal working day - all day) is there any easy way out? Has anyone else had this problem? Is it something I have done which has caused this or is it a problem with Access?
Many thanks
Paul S

Hi all
I have a corrupt MS access 2000 database. It was saved to a flash stick with a compact and repair on close. It seems the flash stick was removed before the compact had completed. Has anyone got any tools that can recover the database? Or maybe point me to some freeware on the net that can recover it?? I appreciate any help.

I have an application which I have split into a database mdb file with the data, and another mdb file with the front end (all the forms, reports, etc). The database file is OK. However, the front end file has some kind of curruption. Running a C/R (Compact and repair) runs clean. The forms and the reports all work OK. But I found a bug in one of the forms, and upon trying to correct it by changing a variable type in the code behind the form, MS Access crashes. I can modify other forms, reports, and modules, but there are about 5 forms (out of about 60) that cause Access to crash.
I have also tried creating a brand new mdb file and copying all the forms, reports, etc out of the corrupted one, but apparently the corruption travels with the forms, because as soon as I copy the forms that make Access crash with the old mdb file, it now crashes with the new mdb file.
Does anybody know of a way to clean something like this, or to export the form and its code so that it can be imported again into anothe mdb? Or maybe someone knows of some program to find and fix these corruption problems in an mdb file?
Anything will be welcome. At this point it is quite a large application and I really don't want to redo it.

Hi Everyone...
Thanks for reading this ahead of time and forgive me for my ignorance.
My father in law runs a business and has a 800MB Access file that is corrupted past the point of compact and repair functions. Some tables can't even be viewed by opening them directly but only through queries (if that makes sense).
I don't know a lot about Access but I have setup a SQL server and an append query to move the data over and for the most part this works ... but ... there are about 100 or so corrupt records per 100,000 in each table ... so I can't append the whole thing but must do a thousand or so at a time until an error appears and then narrow it down to the record and then skip the corrupt records one by one...
What I need to know is ... is there an easier way ? Can I run a query to delete the invalid rows or skip the errors ... or am I just screwed ? I'm worried if I wait too much longer the database will just fall over one day.
Thanks, PB.

Hi all,
Big problems on access 2003.
When opening my live db, the message
"The Visual Basic for applications project in the database is corrupt."
I've had a quick search but can't find a solution.
This db has always been access 2003 (Not converted from prior file version).
I can't even import into a blank db as the same error occurs.
HELP!

How can you find corrupt characters in a table? Also, I tried searching for # but it just throws up numbers! How do I search for # itself?

My table has been corrupting every week and there is only 2-3 people using it on a consistent basis. It will work fine to add new records for a couple of days then they will receive the "duplicate record" error message and it is trying to assign an autonumber that is already being used in the table.
It seems to be picking a random record to restart the autonumber with. I tested it by trying to add a record-it would assign id# 1068 (which is already used) I would get the error, get out, go back into the table and add another record and it would try to assign it #1069 and so on. When it got to a number that wasn't in the table #1071, it would allow the record then. It continues to go through this process, error-ing on id#1072. The record it starts with doesn't seem to have any bad data.
Does anyone know what would cause this to keep happening? I do have another table that ties the id #'s to this first table. When I move records from the first table into another one, or delete them completely, I haven't been removing the data from the second table. Could this cause a problem?
I would appreciate any help with this. I'm am currently working to get a SQL backend done in hopes this will solve these corruption issues.
Thanks,
Toni

I have a record in one of my tables that is corrupt. A few have the fields, including the primary key, have little boxes in them as the data. When I try to delete or change the fields I get an error, The search key was not found in any record. (Error 3709). When I look in the help about the error it says an ISAM SEEK is being executed and there are no matching values in the index. I cannot delete the record or add another one to the table, it gives me the key violation error when i try to just add it again. Any help is apprecited.

Hello everyone. I will admit I am a novice when it comes to access. But I do have some programming background in Lotus Notes. Now maybe its just me but Access seems to error out ALOT and I keep getting messages like:
-File is not a databse
-A user unexpectedly shut down access
-Some c++ runtime errors
I just dont understand what I am doing wrong. I am saving my work like I would do in anyother program. But at least once a day I have to resort to a backup copy because I keep getting errors like the ones above.
I have created an access 2000 DB and it did the same thing about 2 weeks ago...been doing it at least once a day if not more. I have created new db's and still the same thing. I have even converted it to 2003 and still problems.
For example I created a report and was told I didnt have permission to access the report??....WTF..I am the only user in the db as its in development...I created the db..if I dont have permission WHO does. So I tried to add myself in permissions.....then that when I got the c++ error.
I have been working in Notes DBs for the past 6 years and I have to tell you access doesnt have ANYTHING on notes. I have never had such stupid error out of the blue in any program I have used...I mean just closing the DB is causing an error on some days...
I am so frustrated with this its beyond belief..I have a real hard time turning this crap over to my users when I DONT trust it will be running next week...UGH
Some guidance will be most appreciated as I am about to just drop the project and start from scratch in something else.

Cannot Open Database". It may not be a database that your application recognizes, or the file may be corrupt. I have a colleague that is using Microsoft Access to import objects from SQL server but he's getting the above error. I've checked the login my colleagues uses and it has all the right permissions ect but I cannot seem to figure out why this error is still happening. Is it something to do with the SQL server or Microsoft Access?

I had a badly corrupted form in a front end DB. Compact/Repair didn't work. Importing everything into a new DB didn't work .... the db crashed access.
I imported everything except the dud form into a new db and everything was fine. I copied all the fields and controls into a new form.
When it came to copying the VBA, I did it one control/procedure at a time (from the Property Sheet) as I though it was safer.
Was I being over-cautious? Could I have safely copied/pasted all the code in one go ?

Anyone know how to find the path of your backend database using VBA code?
I am trying to determine whether the application is using a database via a network path.

Hi all.
I know Access security has been discussed ad nauseum in these forums and that there is a wealth of information in the archives, nearly all of which I have read often.
And I have a small question.
For years I produced applications which didn't need tight security. However, I tried to stay well informed on the matter.
Security is important in this project. I secured a database properly, as well as I can determine. I then made a copy and deleted all the tables in the one which will be the frontend and linked to the tables in the copy which will be the backend. Only Groups had permissions, individual Users, none. Life was good.
Then I did something, not sure exactly what. The end result is that the frontend seems fine; I cannot open it unless attached via the .mdw I created specifically for this project.
The backend, however, I can open even when attached to the system default .mdw.
Can anyone tell me what I've likely done, and how I might nail down the backend once again?
