Forms :: Opening A Report - Error 3211 / Database Engine Could Not Lock Table
Jul 25, 2013
I have a form that contains a subform. The subform is a datasheet which calls the results of a query of 4 tables (tbl_companies, tbl_deals, tbl_products, tbl_vl).
In the main form there is a button which opens a report with a historical record of dates of value changes of each product up to a chosen date. This chosen date is determined by inputting a date into a text box.
This report also sources (tbl_companies, tbl_deals, tbl_products, tbl_vl).
When I try to open the report, I get the run-time error "3211".
'The database engine could not lock the table "Tbl_companies" because its already in use by another person or process.'
I'm guessing that because the query for the subform is already calling the table, the query for the report can't call the table at the same time?

I have a DB with multiple import processes to take in information and populate various tables. This has been in place for some time and works with no issue.
The import process involves the creation of a local staging table, to which I import the received data, normalise it according to my own table structure, remove any duplication (i.e. same data imported repeatedly) and append the cleansed data to the main tables.
I've just added a validation step to check for data integrity. In other words, for duplicate data, rather than simply purge it as I was doing previously, I now check to see if the data has changed in any way and prompt the user if necessary (with the option to either ignore the change or update the existing record)
However, since I added this extra step, I am getting the following error message during my import process :
Error 3211 : The database engine could not lock table 'tblStaging' because it is already in use by another person or process
It only appears a) when a data change is detected and b) when the option to update is chosen, and seems to occur after the update has taken place (i.e. I can see the records suitably updated)
But I can't replicate the error while debugging so it seems to be a run-time issue. It's definitely not another user as the staging table is deliberately local (specific to that user's front-end)
I suspect I can probably solve the problem by adding some kind of DoEvents call or brief pause somewhere but the problem is, I don't know where the problem is occuring, so I don't know where to add the line? Or if that would even solve the problem at all?
Is there an easy function I can call to check if the staging table is locked? Which I could then use to debug and identify exactly where the lock is causing a problem? Or even apply the DoEvents to release the lock? (It must eventually get released as if I step through the code, I don't get the error?)

I have a live db running on a VPN network (FE/BE both centrally located on a main server , users 'view' their own personal front end through the VPN tunnel) ) and have recently provided a new updateto the FE. Until this time , most users were problem free but one persisted in getting the above error message. Now the new update is in place , they all get it, and this is when no one else is using the db and a single user logs in and tries to use the system. I guess it must be an internal fault ( ie my fault ) but then why does it work for some and not for others?. It also works no problem on my system at home. The user runs Access 2000 and the db was developed in 2003 ( default file format 2000)
Any help most appreciated
Thanks in advance.

I have a form with a combo box that contains a list of customers. Select a customer from the combo box and the form fields populate with general customer info. The form has a subform on it with a combo box where you can select products. Select a product from the combo box and the subform populates with customer-specific product info.
If I open the main form and select a customer, then without doing anything else I select another customer, everything works ok. It’s when I select a product on the subform, and then try to select a different customer on the main form that I get “Run-time error 3211: The database engine could not lock table tblCustomer because it is in use by another person or process.”
Can anybody shed some light on this? I’ve been confounded by it for days.

I am having a problem running a make table query which is based on the same tables that I am using in a sub form.
Basically, the user selects certain records in the subform (which is in datasheet mode) using a check box, then once selected he hits a command button where there is some code that will run the make table query, which I use to filter other tables in a related reports.
However I keep getting this silly "database engine could not lock table" message relating to the sub form name. The subform is not linked to any records in the main form as the main form is unbound.
The solutions offered by putting DoEvents or Me.refresh/Me.requrey in the code do not work.

I've added a list box to my form that displays a table. This table is completely independent and gains it's data from an Append query. There is also a Delete query, which clears the table for a new set of data, and an Alter query which resets an AutoNumber column in the table (so that new data sets always start numbered at 1).
Here's the problem: Since I've added the listbox and set the RowSource to the table, whenever I run the Append query I receive the error: "The database engine could not lock table 'tblLineSheet' because it is already in use by another person or process." I've made sure to close the table, but to no avail I still get this error. Without the List Box I don't encounter this error.

I have tried a million things and have no idea why this is happening. Im not sure what other information i should post in order to see the problem. Any help would be greatly appreciated. Thank you,

Hi,
We have been having intermittent problems with an MS Access 2000 front-end application linked to a SQL Server 2000 database recently.
From the switchboard a user was sometimes getting "There was an error executing the previous command". When she shut the application and opened it again it works fine for a little while - then the error occurs again.
I removed the generic error handling code from the code for the Switchboard form and I got the error message: "The Microsoft Jet database engine cannot find the input table or query 'Switchboard items'. Make sure it exists and that its name is spelled correctly."
I have been searching this forum and the web to find out what the cause of this error message is but I cannot find anything to go on or to try that might help get rid of this problem.
Does anyone know why this error occurs? Any idea how to stop it of happening?
Any ideas or suggestions would be greatly appreciated.

i get this error the time i enter info into a registration page from where i am getting all the customers info
Microsoft JET Database Engine error '80004005'
The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate entries and try again.
in line 74
and my corresponding query is
Set Commrs2 = Server.CreateObject("ADODB.Command")
Commrs2.ActiveConnection=strconnect
line 74: Commrs2.CommandText = "INSERT into registration(username,fname, mname, lname, sex, address, city, state, country, pincode, phone, mobile ,email)VALUES('"&logid&"','"&fname&"','"&mname&"','"&lname&"','"&sex&"','"&add&"','"&city&"','"&state&"','"&country&"','"&pin&"','"&phone&"','"&mobile&"','"&email&"' )"
Commrs2.Execute
Set Commrs3 = Server.CreateObject("ADODB.Command")
Commrs3.ActiveConnection=strconnect
line 79 : Commrs3.CommandText = "INSERT into userpass(username,password) VALUES('"&logid&"','"&pass&"'"
Commrs3.Execute
also sometimes i get this on line 79
Microsoft JET Database Engine error '80040e14'
Syntax error in INSERT INTO statement.
i did a google search and i found this article
http://www.kbalertz.com/kb_884185.aspx
but i was not able to find the security warning dialogue box anywhere
i am using an access 2000 format database
any more info req plz let me know

I am trying to make changes to a particular field in Access but whenever I try to do this, I get an error messsage saying that Microsoft Jet Database Engine Stopped the process because you and another user are attempting to change the same data at the same time.
There is no once accessing the database at this time and this error message appears only when I go to that specific field. I've also tried to delete the whole row but it wouldn't allow me to do that saying the program has been locked.
Any solutions? Thanks,
Rajiv

I have a recursive script that seems to timeout after a few dozen requests, the database is returning the typical "Microsoft JET Database Engineerror '80004005' " error ("Unspecified error").
The code is pretty straight forward, it is a function that calls itself to generate a tree structure for a site map. It works great the first few dozen times but seems to 'time out' and return the above error after a few dozen records (building the tree).
The code looks like this :
Function BuildContent(id,depth)
' open the children
Set GetKids = Server.CreateObject("ADODB.Recordset")
GetKids.ActiveConnection = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=d:usersXXXXhtmldb1.mdb"
GetKids.Source = "SELECT ID,Name FROM category WHERE parent = " & id & ""
GetKids.CursorType = 0
GetKids.CursorLocation = 2
GetKids.LockType = 1
GetKids.Open()
GetKids_numRows = 0
if GetKids.EOF <> true then
MyLinks = countlinks(id)
MyCats = countkids(id)
response.write "Number of Listings (" & GetKids("Name") & "): " & Mylinks & "<br>"
maxdepth = 1
BuildContent = "<ol>"
while GetKids.EOF <> true
KidsCats = countkids(id)
KidsLinks = countlinks(GetKids("id"))
if MyCats > 0 then show = true
if KidsCats > 0 then show = true
if depth < maxdepth then show = false
if KidsLinks > 0 then show = true
if MyLinks > 0 then show = true
if show = true then
BuildContent = BuildContent & "<li><a href='" & GetKids("id") & "_e.asp'>" & GetKids("name") & "</a></li>"
else
BuildContent = BuildContent & "<li>" & GetKids("name") & "</li>"
end if
if depth < maxdepth then BuildContent = BuildContent & BuildContent(GetKids("id"),depth+1)
GetKids.MoveNext
wend
GetKids.Close()
Set GetKids = Nothing
BuildContent = BuildContent & "<br></ol>"
end if
End Function
there are a couple of support fuctions :
Function countkids(id)
Set GetListing = Server.CreateObject("ADODB.Recordset")
GetListing.ActiveConnection = MM_Connection_STRING
GetListing.Source = "select * FROM category WHERE parent = " & id & ""
GetListing.CursorType = 1
GetListing.CursorLocation = 2
GetListing.LockType = 1
GetListing.Open()
GetListing_numRows = 0
countkids = GetListing.RecordCount
GetListing.Close
Set GetListing = Nothing
End Function
Function countlinks(id)
Set GetListing = Server.CreateObject("ADODB.Recordset")
GetListing.ActiveConnection = MM_Connection_STRING
GetListing.Source = "select * FROM records WHERE parent = " & id & ""
GetListing.CursorType = 1
GetListing.CursorLocation = 2
GetListing.LockType = 1
GetListing.Open()
GetListing_numRows = 0
countlinks = GetListing.RecordCount
GetListing.Close
Set GetListing = Nothing
End Function
I think the DB is being called too often, too quickly but I have no way of slowing the script down. If that's the case, is there a way to slow the code execution to give the DB time to catch up?
Otherwise, is it a driver problem (Microsoft JET Database Engineerror '80004005' ) and would switching to a OBDC connection give me better results or should I be using a different db driver?
Any help would be greatly appreciated.

I'm getting this error
Microsoft JET Database Engine error '80040e14'
Syntax error (missing operator) in query _expression '123 street'.
The field in DB is type text. But the data to be written in the field is; number followed by characters. In other words it is an address field on the form, trying to insert new record into DB.
here is 3 different data I entered into field:
1. 'just some text' - works fine
2. 'text and number 123 ' - works fine
3. '123 number and text' - does not work. and gives the above error.
Anybody has any idea?

I have a problem that seems to be happening on several users' databases and is causing a big problem. None of the databases is a shared database...they are all single-user databases on stand-alone computers. I have tried looking for help within previous posts, but all seem to be related to shared databases.
I am getting an error message: "The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time." The database cannot be opened, imported, repaired...nothing seems to work.
Again...these are NOT shared databases. I appreciate any help I can get. I created the database for all of the secretaries in our school district to keep up with absence data. It involves many tables, queries, forms and reports, and has generally worked well. However I am now seeing several that are getting similar errors as mentioned.
Thanks!

Hi All
My department has customer database using microsoft access with the main table being a linked table to SQL-Server database down in IT department.
I've only been recently made aware that the staffs have been having problem when trying to change or delete old data. It keeps on bringing up the error message
The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time.
which is hardly the case since each staff are assigned only one customer to work on.
While it is technically possible to have many people working on the same data, business wise, it is impossible to do that.
I still come up with the same error even when the IT department confirms that no one accessing the SQL-Server table and I was the only one logged in.
This leads me to believe that there is something in the code that somehow preventing the table being edited or deleted. The problem is the database is so huge and was designed by my predecessor so I do not have any knowledge of the complete working of the codes behind it.
If it's the problem with the code, can anyone tell me what sort of codes caused this? If not, can anyone tell me what happened?
Any help would be most appreciated.
Thank you

Hi all,
I got Win2000 and I just developed an intranet solution installed on my web server (IIS). The application worked nicely and there were not any problems. Few days ago I re - installed my OS and I installed the IIS and my intranet solution but there is an error and the application doens't operate correctly with the Access database.
When it tries to retrieve data from the database the following error appears:
Microsoft JET Database Engine (0x80004005)
Unspecified error
The line of the code which is indicated by the error is the following:
objConn.Open("Provider = Microsoft.Jet.OLEDB.4.0; Data Source = "&loc&"; Jet OLEDBatabase Password="&passwd)
I updated Microsoft JET and MDAC. I really don't know how to resolve this problem.
Any help will be appreciated,
ddz

Using an Access 2003 format database, opening in Access 2007...When I try to open my database I get two errors and it will not open.ID is not an index in this table.ParentId is not an index in this table.
I get the error when it opens with autoexec and when I bypass autoexec. I have a master copy of the database that I tried to link to the first database to import tables but I still get the error.

I attempted to add new queries, reports, and a form to a shared database. It bombed out and I found that a user was changing data in the tables at the same time.
Now I cannot access the database at all (front or backend) and receive the error message: “The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time”. (I have verified that no users are currently logged in.)
Access to the data is critical to my department and I’m scrambling to fix this. Can anyone assist me?
Thanks!

how to deal with errors specifically with error "The Microsoft Access database engine cannot find a record in table".Database which I'm creating have table Products, which contains information about products. Most important information in this table is if product is VATable or not. I decided to define product names in invoice table that database can recognize products and calculate VAT in invoices if product is VATable. Problem starts if you have new product. When I add new product in invoice it counts VAT but when i go to next record I receive message mentioned above. It doesn't allows me to go to next record or save record.
I was wondering is it possible to make it that access allows to fill invoice, informs about new products only when i have finished adding all products in invoice and than gives opportunity to add them to product list?

I have included the form control [Forms]![AddMatterFrm]![MatterIdFld] in the criteria of the first of three queries.
1st Query - with the form control isolates transactions relative to the contents of the form variable (coming from an open Form)
The second query is a XTAB query further processing and summarising the transaction.
The 3rd one adds another expression field.
I execute the 3rd Query using the command below
Set rstDebtTrans3Qry = db.OpenRecordset("DebtTrans3Qry")
I then get the ....Database Engine does not recognise [Forms]![AddMatterFrm]![MatterIdFld] as a valid field name or expression.
If I take the control reference out and hard wire the value I want - there is no problem.
I'm sure it has something to do with the XTAB query but I need a solution.

Hello everyone,
I have written some code that will add some entries to a table:
Set myTable1 = db.TableDefs("Weekly_Card")
Set rst1 = myTable1.OpenRecordset(dbOpenDynaset, dbOptimistic)
While i < arrayCounter
With rst1
.AddNew
![ProjectID] = projectNames(i)
![MemberID] = usrName
![WeekNo] = noWeek
.Update
End With
i = i + 1
Wend
The problem is that when i am trying to execute this code a form is already open that is bound to the table and so i get the followng error:
"3211" Runtime error
"The Database engine could not lock table "Weekly Card" because its already in use by another person or process"
Now my questions are:
Is there a way to access the table and add data to it whilst it is being used ?
Is there a way around this problem?
I am using Microsoft Office access 2003.
Thanks in advance

I have 3 combo boxes on my form and I am trying to update the second by the choice made on the first. I have a query for each box that when a selection is made it makes a table of information I use in the next box, and after I select something from the first box I get this error, but it does populate the second list. Any help would be really appreciated. Thanks.

At some point I get this Error: The Microsoft Access database engine cannot find the input table or query <name>. Make sure it exists and that its name is spelled correctly.

I want to create a report using the data currently held in a form. I found this bit of code somewhere:
DoCmd.OpenReport "report", acViewPreview, , "[job number] = " & txtFilter.Value
txtFilter is the name of textbox containing the data I want for the report. This works if in the table for txtFilter's data the field is set to a number. But if I set this field to text it comes up with a data type mismatch error. How do I solve this? (sorry new to access and vba). The reason I want to set it as a text field is so that I can limit the number of characters entered.
Thanks

Good afternoon,
When I'm trying to open a back end database which was previously created is MS Access 97 it gives me the following error;
Cannot update. Database or object is read-only.
I have tried running the "Compact/Repair Function of MS Access 97 and MS Access 2003 to no avail.
I have tried converting the back-end to Access 2003 as well but I still get the same error message. I can link to the database tables from an Access 2003 database fine with no error message!!
Has anyone got any suggestions before I have to take it offline and rebuild the back-end and then copy the data across from the old one?!!!
