List Box Causing Database Engine Could Not Lock Table
Jul 12, 2014
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 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 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 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 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'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.
I have an App that runs a few action queries using:
Code: CurrentDb.Execute "[My Query Name]"
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. (Error 3078).The query is there, I can run it from the DB objects window.Queries run using CurrentDb.Execute earlier in the code.
I'm trying to run a UNION query that joins five queries through a MS WorkSpace into a DAO.recordset in VB. I'm pulling the data from a SQL Server Database through VB in Access. I'm attempting to open a recordset with a query passed to it as a string. The query is below. For some reason, I'm receiving a message: "MS Jet database engine cannot find the input table or query. Runtime Error 3078".
Here's what's puzzling. When I run a single query without any UNION statement, the code finds the table and runs fine without error, but anytime I join two or more queries with a UNION statement in the VB, it gives me the error.
I've executed the same UNION query in both Access Query Builder and SQL Server's Query Analyzer and they work fine in both environments. It's only when I call the query from a DAO.Recodset with VB that it causes this problem. The following is a sample of the UNION query joining two of the five queries. Does anyone have any idea what could be the problem? The following query executes in about 5 seconds so I don't think there's a "time-out" issue. I'm thinking that the UNION statement may be the culprit. Maybe there's another way to approach joining these separate queries? Any help would be most appreciated. Thanks.

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.
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.
Start with: frm_W-GraphSearch select from combo and ever this for date criteria: 12/1/06 to 12/13/06 Open report - There you will see one out of three graphs showing Go to Report Design mode and open the sql in one of the graphs and try to run it, there you see the error:
"The Mocrosoft Jet engine does not recognize 'Forms![W-GraphSearch].Text0' as a valid field name or expression."
Dear All, I prepared times ago a database that contains important data that will be frequently updated. Since yesterday I cannot load the database anymore. I get a pop-up with following statement: Quote The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time Unquote If I click ok, the loading process will be aborted. I'm the only user of this database, neither the database nor the directory containing the database is sharable. It is located on the harddisk of my computer which nobody from outside can access. What can I do to recover the access to my database?
I use MS Office 2003 but tried to open the database also on MS Office 2000 with the same result. The Help function of MS-Access does not really help. Who knows how to solve the probleem???? With regards Siegfried
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 trying to access a Microsoft Access database located on a server on my network from my web server. The folder containing the access database has been shared on the network with everyone having full access. I created a virtual directory on my web server pointing to the share on the other server and when I try to connect it says:
Microsoft JET Database Engine (0x80004005) The Microsoft Jet database engine cannot open the file '\server1databasejt_test.mdb'. It is already opened exclusively by another user, or you need permission to view its data.
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.
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
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?
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?
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?
I am working on a database that uses a table from another access database. I am not sure but I think the problem started after this line was added to the code:
Set dbk = OpenDatabase("D:My documentsJapiOritaColorBazeKnjigovodstvo1.1.md b")
The database still works fine on one machine. When I copy it to another machine, that is when I receive 3197 error.
When I copy database to another machine without the code that contains the line from above, and copy the same code in the same form after opening copied databse, the problem is solved.
Does anybody know why is this happening? How can I fix this?
I have created a db that is used strictly for data entry. I have one main form with about 6 embedded subforms and the db is broken down into a FE/BE. I currently only have one user in the database and sometimes when the user tabs into one of the subforms the will receive error 3197. I have searched the forum and have read that this error may be caused by a OLE or memo field but I have neither. There is no pattern to the error it seems to happen sporadically. Any ideas?
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,
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 am currently using Access 2010, and have successfully split a database, using the Access wizard.However, whenever a second or third user opens the database - with their front-end database file - they encounter the following message;The Microsoft Access Database engine cannot open or write to the file ". It is already opened exclusively by another user, or you need permission to view and write its data.
I have researched the internet and see that it has something to do with network permissions. I have worked with my IT department and this appears to be resolved!
Is there a setting I need to check in the front-end and/or back-end copies of the databases?Why is there no file name in the error message?
