Tables :: Automatic Refresh Of Linked Tables - ODBC Connection
Jul 22, 2015I have linked tables from SQL Server using ODBC connection that their location never changes. I have used certain fields of those tables to create queries and make table queries to derive to the information I needed.
On these tables on SQL Server, there is new data added daily. Every day, midnight, there's new data records added of whatever transactions took place in that working day. how often do I need to refresh linked tables in this case to get the latest data added. I mean, once I am linked, the make table query using those defined fields, would it get the latest data added by default when the query is executed, or I must refresh linked tables using Linked Table Manager and then run make table query.
Also, if I want the access to automatically refresh linked tables, can I use the following code? I have added this code, and executing it through a button, but I don't see anything happen, the database becomes inactive for couple seconds (I guess while it is updating) but I don't know is it updating the tables for sure or not, though I am not receiving any error when executing the code through the button.
Function RefreshLinkedTables()
Dim tdf As TableDef
For Each tdf In CurrentDb.TableDefs
If Len(tdf.Connect) > 0 Then
tdf.RefreshLink
End If
Next td
End Function
Modules & VBA :: Refresh Linked Tables When Connection Lost Without Closing Access Database
Sep 4, 2014I 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...

Jan 25, 2007I've been creating a new Access application and I've run into an issue. The form I created has 2 subforms on it. The data is stored on 3 different tables related by the RMAID. The data gathered from this form needs to go into our MRP application. I have linked the necessary MRP tables to my access application. How do I get the date from the form to the tables in our MRP application? The data needs to go to 3 tables from the MRP application. Do I create an append query that's run after the user completes entering the data on the form? Thanks for any help
View 1 Replies View RelatedUpdate Linked Tables When Used In Queries
Jan 23, 2008I have set up a table (A) that is linked to another table(B) in my database. This linked table (A) is then used in a number of queries. When the data in the original table (A) is updated it does update the data in the linked table (B) as it should. However, when I run the queries they do not bring up any records. It seems that they are not looking at an updated version of the linked table (A) because if I rebuild the query it finds the records as it should. Any advice on this would be very gratefully received.

Jan 22, 2015I have an access database with a linked table to an Excel spreadsheet. I have a form based on the linked table so the presentation of the Excel date is better. The spreadsheet is used by other staff in my office to record sales which I need to register with an external organisation. What I want to do is update the spreadsheet with the registration date from my access form rather than going back into excel to do it.
View 2 Replies View RelatedSplit Database. Update Linked Tables If Back End Moved.
Dec 7, 2007Hi.
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.
Many thanks in advance.

How To Create A Form That Can Update Data Linked To Multiple Tables
Jul 30, 2012I'm using Access and Excel 2007.... I know how to import an Excel spreadsheet as a table.
I have several supplier price lists in Excel. I want to keep my vendor price lists up to date.
When one of my vendors tell me that a price has changed on a particular item, I figure that I could have a form that I could use to enter the changes.
I believe the form would look like:
Field: "Vendor" (drop down list to choose from. Name of the Supplier price lists) Required.
Field: "OEM" (Key Field found in each table) Required.
Field: "Brand" (Field found in each table) Not required.
Field: "Price" (Field found in each table) Required.
OEM would be the unique key field.
If I enter the Vendor name and then the OEM number it would show if there is already that number in the Vendor price list and I could make changes. Or I could enter new data in that vendor price list.
Modules & VBA :: Refresh Query NOT Linked To Form Or Report
Oct 14, 2013I am making a booking system where a user enters
StartDate, EndDate (Form Header)
House , Room , UserID (Form Footer)
The Header and footer are not linked. The Footer simply displays all the existing bookings for said ouse/Room/Date combination. (Date being all dates between the StartDate and EndDate) BUT (surprise, surprise)users don't look at this to check if a booking already exists.
Also - It seems pointless to have the users enter the same data (House, Room, UserID) in 6 times (one for each day that they want to book the room.
So I am trying to automate the process.
Therefore, I append each 'new' record (that the users adds in this session) into a temporary table. (House / Room / UserID / StartDate)....note, no end date because I need a separate record for each day.
I have a query that is supposed to check the EXISTING bookings with the temp table.
My code (paraphrased here for simplicty) says
do while StartDate < EndDate
- if Qry_CheckForClash returns 0 records then '(uses a dlookup)
- append from TEMP to BOOKINGS.
- - else
- compile an alert message to the user (appending the Room No and Date each iteration)
- In Qry_CheckForClash, increase the StartDate by +1
- end if
loop
My problem is that after the last step (increase StartDate by +1) the call to Qry_CheckForClash still returns the initial StartDate. But when I check the TEMP table, the StartDate has changed.
So how do I REFRESH or REQUERY a query that is not associated to a form or report?
Forms :: Refresh Form After Update Query
Sep 28, 2014I have a form that has a check box on it. For some reason the check box is not being checked when an update query is run prior to load. I issued the 'Me.Requery' command after the update query is run (via 'On Load' and 'On Open' in the 'Event' property . . . neither worked) of the form. Is this the correct way to refresh a form after an update query is run ?
View 8 Replies View RelatedRelinking Multiple Linked Tables That Are Linked To Different Databases
Feb 2, 2012I have a database with a number of linked tables that are linked to tables in different databases (not a back-end).for example, I have table1 that is linked to table1 in K:databasedb1.mdb.table2 linked to table2 in S:datadata.mdb.and so on...
However, recently we have moved all our databases to a new location.
K:databasedb1.mdb is now residing in O:masterdatabase
and S:datadata.mdb is now residing in O:masterdata
and so on...
I'm now in charge of relinking all those tables to point to the new location.I would do this in linked table manager one by one but we have 100s of tables linked to multiple different databases in different location.is there a way to create a VBA code that will automatically do this re-linking process?
so,
1. find unlinkable tables
2. search its new location under O:master
3. re-link it to the new location
Database names and tables names have not been changed. Just the location of databases.
Refresh Access Tables From Dbf Files.
Sep 3, 2004Hi,
I have several dbf files that I imported into Access in order to establish relationships and export as spreadsheets. I have created a macro that does that. However, the dbf files are based on a query that changes monthly. I was wondering if there was any way to automatically update the tables from the dbf files once the queries are run without manually importing the tables again?
Thank you for any assistance.
Automatically Refresh Datasheet / Tables
Feb 7, 2012I have an access file which connects to an ODBC database, and I want it to update at a set time interval.
I searched through the internet, and noticed that most solutions require a form and putting the requery macro in the form's events.
My file doesn't need a form, its only function is to act as a medium to store the data from ODBC and lets a BI Tool play around with it.
My question is, how do I make the access file update automatically at a timely interval (every 30 mins, 1 hr etc.). Is it necessary to create a form?
Tables :: Code To Refresh Sharepoint List Links?
Oct 29, 2012I found 2 examples of code to refresh my attached table link to sharepoint lists.
I have a scheduled task open my Access 2010 db and an autoexec macro runs and closes the db.
My problem is my tables disconnect from sharepoint 2010 and the update fails.
I added the code I found to a module and added a line in my macro to run the code. Now I cannot get the code to work.
Am I at least on the right track? I just want to know before I spend many hours getting this code to work.
These are the two locations of code I found.
[URL]
I think part of my problem is that I have a regular table that I add a txt file to that is not linked to sharepoint so I need to exclude it from the code.

Tables :: Data In Linked Back End Tables Not Saved From Front End
Jun 19, 2015I have split database (B/E is in the SharePoint library, F/E has users on a local PCs). Sometimes, when I update/add data (does not matter if it is via form or directly in the table) it looks OK, but when I re-open the database, the data are gone.
Problem is that I cannot catch the moment when data were not saved (sometimes data are saved, sometimes not). I can point out this: if I re-enter the missing data, primary key continues subsequently, it looks like the data have never been entered. I tried to use script
Code:
If Me.Dirty Then Me.Dirty = False
on "On Close" form event, does not work.
B/E is linked by VBA code and it looks OK (no error, Link Manager shows correct path). I suspect interrupted connetion to the SharePoint but I don't know how to check it. I implemented VBA script co keep open connection to the SP but the issue persists.
Update / Refresh A Form Upon Entering Data In A Popup Box / Form
May 24, 2005I apologize if this has probably been asked countless times; however, in my search of this forum I could not find something that seemed to work for something so simple.
**************************************************
Scenerio:
I have 2 forms. The first form is my main form and the second form is my "popup" form. Both of these forms access the same table. In my main form I have it so people can not enter in a ID so it reduces accidental data entry. Therefore, I created a "popup" box that allows ID entry.
Everything works great except when I close out of the popup form, the newly entered data is not available unless I close the main form and reopen.
Million Dollar Question:
How do I refresh or requery (dunno the correct term usage here) the main form to reflect the addition I made in my popup form. I would like the refresh event to happen when I click the close button on my popup form.
**************************************************
Again, I know this is probably simple, but I cannot find it anywhere or most likely I am blind :cool:
Thank You

Tables :: Access 2010 / How To Rename Linked Tables
Nov 11, 2014I 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.
Is this possible using vba in the frontend?
Last Update To Linked Spreadsheet
Nov 30, 2011I export data from a system to an excel spreadsheet, which is linked to my database. When I run reports in Access, is there any way to identify when the linked table was last updated? This would be useful to users if I could add a text box that shows "Data current as of" some date.
View 7 Replies View RelatedSubform Refresh After Combo Update For "<ALL>"
Jun 2, 2005Hi All,
This is driving me nuts!!
I have a form with a combo box that populates a subform with data equal to the combo box value. I have added "<ALL>" to the combo box to display all records if selected. The after update code changes the queryDefs. The problem I have is that when "<ALL>" is selected, no records show. But the query has updated. If I close the main form and reopen it all the records show, but if I select a new value nothing happpens. But the actual query has updated. I have tried many combinations of refresh, repaint...etc.
Anyway, here is the code, any help appreciated.
Private Sub cboFeedMtrl_AfterUpdate()
Dim qryAllMat As QueryDef
Dim sql As String
Set dbsCurrent = CurrentDb
Set qryAllMat = dbsCurrent.QueryDefs("qryViewData")
If Me![cboFeedMtrl].Value = "<ALL>" Then
qryAllMat.sql = "SELECT * FROM tblMachineSelection"
Me![frmViewData].Requery
Else
qryAllMat.sql = "SELECT * FROM tblMachineSelection where [feed Material] = [Forms]![frmView]![cboFeedMtrl]"
Me![frmViewData].Requery
End If

Update Linked Table Definitions
Apr 27, 2005If a front-end database has links to many tables in a back-end database and the back-end is moved, is there an easy way to update all the table links in the front-end in one go, or do you have to set up all the links again one at a time?
Hoping there's a quick way...
Dave
edit: just realised the previous post asks exactly the same thing ( :o ), but that hasn't elicited a solution yet ( :( ).
Can't Update Records In Linked Table
Apr 2, 2006I have done everything I can think of to remedy this, but I can't figure out why this is happening. I have a linked table from excel that contains 5 fields for each record. I have a table in access with matching records and 20-30 fields. The linked spreadsheet is used when adding records. I have a query that queries both tables to get all data from both and a form based on that query where others can pertinent data for the records resulting from the query. My problem is that when I open the form the new records that were added in the linked file are there but all the fields from the access table cannot be updated. I have looked every place I know to look for record locks, read only options, everything I can think of why i cannot update these records and I am coming up empty. I checked my join properties and selected the only one that actually displays the linked records when the query is run (not sure the name of the join but it's #2 of 3 join properties options (in Access 2002). maybe I am just overlooking something simple? Do you have any ideas what I can do here?
Thanks!
Won't Update: Subform Linked By Combo
Apr 6, 2005I have a form that I have linked (master/child) to a combo box on my main form. I have a requery command for the subform set to the "After Update" event on the combo box. When the combo box is updated originally, the subform updates. However, if the combo box is updated after having a value, the subform does not update.
First off, is the requery command even the right command to use to update the subform? (it's source object is a table) Second, is there a reason it wouldn't work if that is the correct command?
Any ideas?
Linked Forms- Foreign Key Update
Apr 30, 2006Hi,
i need help regarding linked forms..
i have a combo box in a form, where one has to select a country for example UK is chosen, then there is a button that when clicked it opens in a pop-up form and displays all the information related to UK.
so there are two tables : Country (CountryNo : primary key) linked to CountryInfo (CountryNo: foreign key) linked with a one- to -many relationship.
my problem is when you have to add new records to the form CountryInfo, how can i make the foreign key update automatically? thus when adding data to CountryInfo, the CountryNo must be the same to the CountryNo in the CountryTable..
any help will be appreciated thanks a lot.
