Default Parameters Which Slow Down Access Database Linked Tables?
Jun 29, 2012
I recall reading somewhere (fairly recently) about a parameter or property in Access which is "On" by default and allows a form/query to identify when backend table field names or query arguments are changed and automatically looks for and "fixes" the renamed link. By leaving this switched ON, the database is slower than it could be. The db speed performance can be can be improved significantly by switching this 'feature' off. (i.e. Name of the property)
I created an Access Application already and i placed the application on the server and noticed it to be slow in loading the forms and retrieving data.
So I figure if I linked the tables of my application and place only the table on the server, and have the GUI be stored local on User computer it would run faster. But I find it to be even more slower. Can anyone help me out figuring why is this? All I did was use the database splitter feature of MS Access 2000 to link all of my tables.
I have a couple of acces databases running on a peer to peer network (database A and B, which are housed on PC1). The database B has a link to a Customer table in database A. This was running fine until another user on the peer to peer network wanted to use database B on their pc (PC2). I had to change the the file location of the linked table to show it's location on the network so PC2 could open it. Unfortunatley this greatly slowed the operation of the database B on both machines. If anyone has made it this far - Is there any way round this?
I have a question that I have a Microsoft Access database (.accdb) front-end/backend split and I want to give the database to my company client. As we have the different path for the backend/frontend linked. I want some code that will popup if the database location is not found and popup with the dialog so the user then select the backend and it would be ready and there is no need to popup each time the database open, it would run once it did not find the last linked path.
Also I have tried the code of Dev Ashish URL.... but unfortunately it would ask everytime to refresh the table links and I only want to run the process of linking tables when the database start and the linked path not found.
I have MDB database linked to SQL SERVER through VPN connection.I created links to the sql server Links are dsnless..Everything works fine but when I lost VPN connection or sql connection has been broken I can't refresh links to the tables.I receive message 3146 sql connection failed..I must close database and start again...
I tried different methods like ado,dao, and vba docmd.transferdatabase,aclink... but no success, table cant be relinked.
Only way I can relink is to change ip adress in conn.string
E.g. 192.124.0.2 (1st ip- router server ip) and after connection failed i can use 192.124.0.32 (2nd ip - server local ip) and that's it if i lost connection for the 3rd time... i must restart application.
It seems that access database keep the previous connection..how to reset or drop database connection to the sql server and refresh links to the tables with vba code without closing access database...
Hi everybody, I have an access database which is around 40 MB after compacting it and I feel that it is slow especially when I open cross table form. Is there any way to speedup the databse. Note: my databse is on the share drive in my work.
I'm having trouble with access. Basically it has been very slow to load (over 30 seconds when not opening a database) and when opening a database it just crashes.
Has anyone any idea what could cause this as it worked fine before ?
looking for a way to export the list of table names, table types & if they are linked (e.g. tbl Sales Linked .dbf or tbl Staff linked to excel) from a database - this has to be done for about 300 databases.
in an individual db, I have a make table query off of the table MSysObjects to get the data. The Database field tells me where the source of the linked table resides & the ForeignName field gives me an idea of the format of the data source (e.g. dbf or excel). I could manually import that query into each db, run it to get the table names, then copy & paste..
I have developed a Microsoft Access 2010 database for my client and the database is split with Front-end/Back-end, the Back-end and the database is shared on Network, The client operating system and applications for all users are hosted and consistent and the service is delivered over Citrix.
The database some times corrupt the tables record and give a permanent #Delete Error, I have attached one of the database table and the screenshot of the error,
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??
I have a split database.(Access 2010).Three of the linked tables are Appointments, Appointments_OLD, Appointments_NEW.
I want to use vba to rename Appointments as Appointments_OLD (replacing the current one) and to rename Appointments_NEW as Appointments (replacing the current one)
I have used:
'replace Appointments_OLD by Appointments, replace Appointments by Appointments_NEW DoCmd.Rename "Appointments_OLD", acTable, "Appointments" DoCmd.CopyObject , "Appointments", acTable, , "Appointments_NEW"
Unfortunately this just made Appointments and Appointments_NEW clones of one another - changes in one automatically occur in the other.
What I actually want to do is to swap the names round in the backend database while maintaining the right links to the frontend.
I'm about to move to a back end / front end system, from a single database file. Before I do so, I want to make sure I have all bases covered so to speak.
My back end file will reside on a server. I am aware that path names are sometimes changed by network administrators without warning.
From tests, I notice that, if the path to the back end can't be found, one cannot open the front end database file at all (Access 2003).
My question is: if my back end file gets moved, or the path changed, how can I get into my front end file to update the linked tables.
I have built a database and within it my queries I use for reporting make tables in a separate database. This allows me to work in my data base and update info as needed. My problem is that my make table queries wont run if anyone has one of the report pivot tables open. I have added macros to all the Excel files that pull from the reporting DB but I still have several times when I cannot update because someone is using the pivot table, Is there a way to allow me to update the report DB's while the pivot tables are open? I have tried using manual refresh methods and disabling auto update on open but the result is the same.
This may be a simple question, but I'd like to reassure myself, so here goes. I have a database which is used to produce a pile of reports, and the tables are linked to a second database. I now need to update the reports, and add new data for this year. But the second database is password protected, and yep, I don't know that password. (I'm taking over this project from someone who left 3 years ago - I haven't just forgotten the password honest!)
Is it ok to import new data to the second database, and still carry on producing reports?
What if I want to change the properties in one of my linked tables? Can I delete the link, change the property, and then reapply the link?
Hi, There seem to be a serious bug in Access 97, and I want to know if anyone has encountered this before. I tried to describe the problem as best as I can, I also included a flash video to describe everything, here it is: http://naderchehab.googlepages.com/linkedtablebug.swf (~1 MB)
My database has two tables: - dbo_InventoryLocation which is linking to SQL Server 2000 via ODBC which contains inventory quantities for each product, and - tblPRODUCTS_BUSINESS which is linking to another access database on the network and contains product information (item number, title, description, and a field called "InvCategory" which describes item categories). I wrote a very simple query that links these two tables together:
SELECT tblPRODUCTS_BUSINESS.InvCategory, dbo_InventoryLocation.ItemNumber FROM tblPRODUCTS_BUSINESS INNER JOIN dbo_InventoryLocation ON tblPRODUCTS_BUSINESS.Item_Number = dbo_InventoryLocation.ItemNumber GROUP BY tblPRODUCTS_BUSINESS.InvCategory, dbo_InventoryLocation.ItemNumber ORDER BY tblPRODUCTS_BUSINESS.InvCategory;
The query really doesn't matter, it's just a test. Now here's the weird part: when I execute this query, and I scroll down to a specific category and count the number of items in that category, I see about 50 of them. But if I specify that category as a criteria, I see more than 200!
I also noticed that this problem does not happen when I use non-linked tables.
I hope anyone has an idea what that problem might be, and I hope there is a way around it.
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.
Wondering if anybody has any information about this.
Backgound information: My access database information comes from a 'card' where somebody has manually put crosses in a number of boxes. This information is currently being manually inputted into the database...
I know you can get scanners to pick up information from a document...but is this possible with microsoft access?

Hi, My access database's tables are currently linked to an excel document. My question is, how do I move my database to the network? Currently when I move the the database to the network no one can open my tables because the link goes to my documents on my computer which they can't access on the network. So how do I move the database and maintain the link between the database and my tables?
We are sharing an Access 2003 database amongst two departments that contains twelve (12) tables that are SQL Server linked tables. Nine (9) of the tables work just fine for people in both departments. Three (3) of the tables cannot be opened until the user refreshes the link(s) using their ODBC DSN.
We do not understand why nine of the tables work without issue but three will not.
Has anyone ever run into this issue before? Does anyone have any ideas on how to resolve this issue?

This problem is driving me nuts!! I`ve just spent a fair few months creating a database to be used by our sales team, I`ve about finished it and came to trial it with the sales manager. When he is using the database at the same time as me it becomes slow. The design has a front end with all the queries, forms etc and a back end on a server containing the tables. The database was created using Access 2000 and was designed to replace a similair db created on 97 which has a decent speed on the network. The other strange thing is that one particular macro that I`ve been using for the speed tests runs quite slow (about 3 secs) when 2 pcs have the db open but once the macro has run if it is run again it takes typically less than a second to run. What would cause a db to run a macro at different speeds after they`ve been run once? I`ve tried everything I can find on the net to try and improve the speed to no avail. Help please!!
