Modules & VBA :: Errors Caused By Not Using Linked Tables?
Jul 23, 2013
I have a separate front and back end for my database. I`m trying to merge them into one application, for easier distribution to users, but I`ve found that things that worked previously now produce errors, even though all I`ve done is import the tables as opposed to linking to them.
For example, the line:
Forms!Referrals!Paycode = str_Paycode
works perfectly if using linked tables, but if the links are all removed and the exact same tables are imported, I get the message 'Object invalid or no longer set'.
Is there some difference between linked and 'in-built' tables that I'm missing?
I have linked tables in my db at the moment that rely on user dsn connections to an SQL server. I've been reading about DSNLess connections and want to try convert what i have to have permanent DSNless connections, but the code I've found doesn't appear to be working.
I've removed server specific details where i felt necessary, but when running the code i have it in place.
Code:
Public Sub RefreshODBCLinks() Dim connString As String Dim db As DAO.Database Dim tb As DAO.TableDef connString = "DRIVER=SQL Server;SERVER=<database ip address>;DATABASE=<
I have the following script that either converts a single linked table to a local table or ALL linked tables to local tables, however I am getting the following 2 error messages on several tables for the ALL tables script.
error 3709, the search key was not found in any record
Error 3300, cannot create a relationship.
Code: Sub Convert_Linked_Tables_To_Local() Dim dbs As DAO.Database Dim tdf As DAO.TableDef Set dbs = CurrentDb GoTo Multi1
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...
Having searched the last couple of days, I am unable to find a resolution to this problem. If it has been answered already, a simply link or thread name would be appreciated. If not, help is greatly appreciated.
I have code running that imports data from a .txt file into a table.however, on some days there will be errors importing some of the data. I have found that from the last three months, there has been no data of consequence lost so, I don't care about the data errors. However, any time there is an error with the import it creates a table that is named for example:
01-03-05 Auth_ImportErrors
where "01-03-05 Auth" is the name of the file imported. So each time they import a file, a new table is created. Is there any code that I can run that can automatically delete these tables upon exit?
I 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.
Wonder if anyone might be able to help me out. In the detail section of Access report, there is three subreports laid out as follows
subreport1 subreport2 subreport3
Depending on the certain criteria, subreport1 and subreport2 may appear in the report. subreport3 will always appear on the report.
The problem that i'm having now is when subreport1 and subreport2 do not appear in the report, thet seem to occupy the space. Hence, when viewing the report, there is a huge gap. My question is whether there is a way of removing the gap there.
I've found one thread on this forum which appeared to cover the problem I'm having, but it was from a few years ago and stopped rather abruptly.
I have a combo box with five fields. The row source for the box is shown below and includes a value that I obtain from dividing one figure by another. All is well until I try to order the box's contents by this value, at which time I'm getting an 'Overflow' message.
The full query is as follows, with the problem area in itallics.
When the input value for m is empty/Null, the response returned in the query is #Error. Problem is, any way I try to test for this in the function, it still returns #Error.The Watch for m reads "<Out of Context>" for these errors. Anyway to test/trap for this within the function itself?
Code: Public Function getAbsoluteMagnitude(m As Double, d As Double, Optional dUnit As String = "Mpc") As Double Dim absoluteMag As Double ' IsError(m) returns False ' IsNull(m) returns False ' IsEmpty(m) returns False
I have a calculated field Labeled [Hours/Month], simply enough, it is calculated by dividing one field [Hours] by the other field [Months].
The field calculates just fine as 0 or null values are not part of the data set. However, I am trying to write a query that parses this data where the calculation (Hours/Month) is greater than (750/36 or 20.83).
I would expect to just be able to plug ">750/36" into the criteria, but this gives an overflow error, as does ">20.83". I don't want to have to write this data set to a table before being able to add this simple criteria, why this is happening?
I created a query that pulls information from 2 other queries and everything was going fine until I saved the query. I now get a circular reference error
SELECT [CashValue Link Query1].Facility, [CashValue Link Query1].[Financial Class], [CashValue Link Query1].Date, [CashValue Link Query1].Date, [CashValue Link Query1].[Total A/R], [CashValue Link Query1].Current,
I have the following code, which works the way I want it to when I click the button the first time. However, if I close out the excel and click the button again, it errors at the line "ActiveWorkbook.Worksheets("Ref").UnProtect", with the message "Run-time error '91', Object variable or With block variable not set". I can not figure this out, why in the world does it work the first time, but not the second???
Private Sub cmdReport_Click() Dim path As String Dim XL As Object Dim oBook As Excel.Workbook Dim pic As Excel.Shape Set XL = CreateObject("Excel.Application")
Custom filter I'm trying to set up. I have a data full of records with multiple columns and a form linked up to it. The form has a search box that works as well as navigation buttons.
Currently I am trying to get a filter to work. The filter will use up to five combo foxes to narrow down the fields, then return the filtered records after clicking a button. The button itself is where my code is. My issue now though is I cannot get the filter to work if I try to use more than one combo box.
The code I have at the moment is as follows: '------------------------------------------------------------ ' cmdApplyFilter_Click ' '------------------------------------------------------------ Private Sub cmdApplyFilter_Click()
End SubThe current error I am getting is Error 13: Type mismatch. I also know that the And might be the cause but I cannot change it to AND: it keeps changing back.
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 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.
I 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
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.
Hello All, I currently have a bunch of tables that I have linked to a SQL database. For development purposes (easy of use), I'd like to turn all those tables into regular tables rather than linked so if I take the db offsite, all the data is with me. I realize there will be no updates, etc. but that really doesn't matter for my needs in this case.
Is there a script or an easy way to do this? (besides doing a manual import for a LOT of tables)
I've tried searching but I might not be searching for the correct terminology.
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 one database called asset management. It consists of one main table called cyber assets. Most fields in this table are linked to a manually created lookup table inorder to restrict user input. There are also two additional, none lookup, tables used to list a) the IP addresses (there can be more than one) and b) another similar 1 to many type table. Basically this DB is used to manage basic cyber asset data, excluding most items related to configuration management.
So, this above DB serves the purposes of asset management. Now I essentially need a similar DB for Patch Management. What I've done for this is to assess each patch initially (i.e. just by looking at the patch title and determining if we even have any of those device. i.e. this assessment is not based on OS, model number... just a general 'may' or 'may not' be applicable). Here's what this SEPARATE DB looked like:
Since each patch is essentially assessed against itself, or maybe a better way to describe it is against the users memory of what we do and don't have, only a single table and form was needed.
So now we've been thru this process and the DB is filled, all initial assessments are complete. The next step is to take all the ones that are applicable to our company (based on the initial assessment when you answer, yes is applicable) and do assessments based on each device we have.So what I want to do is to link the two DBs on a new table called Patches_by_device, inside the original patching DB... so the relationships would look like this:
But as you can see, the linked table CYBER_ASSETS has some sort of undefined relationship type, which is causing my issues.So the next thing I did was to autocreate a form based on the Patches_by_device table, and here's the result.I need to change the patch_key to the Patch_ID+Patch description+URL, etc, and to change the device key to the the UNID+IP+functional description, etc...so I changed the form record source like this:
Now I should be able to change the control source of the Patch_key and Device_key to more useful information. so I changed: Patch_key control source to Patch_ID and Device_key control source to UNID (which is in the cyber assets table)
As you can see, it worked for the patch_ID but not the UNID which is part of the linked table.Must it be within one DB, because we have a ton of other modules to implement (e.g. config management, vulnerability assessments, audit stuff, and more...) and I'd like all these to be in individual DBs, all liked back to the main cyber_assets/Asset management DB.I've considered just modifying that patch table so that each device has its own column heading in the table, but this will cause issues when new devices are added.
I am taking over a database someone else created but is no longer here. The tables are linked to an external oracle database. I know the links exist because when I run a query it prompts me for my user name and password. However, the tables look like regular tables. There is no icon showing it's a linked table so I don't know which tables are actually linked and pulling from the Oracle database.
I have a database with the tables linked from another database. The problem is that i need to copy the database to and from another machine in order to work on it. As this involves putting it in a different location each time, i have to relink the tables. Is there a way to link the tables reletively so that as long as they are in the same Directory they will be linked?
