Tables :: Data In Linked Back End Tables Not Saved From Front End
Jun 19, 2015
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 am splitting a database and have created the Back end already. When I create the front end and link to the tables on the back end... The front end does not link to all the tables in the back end. The list that comes up when creating the linkings does not show all the tables in the back end. What would cause this?
I'm a bit new to Access but have managed to build a very simple database.
I have a main table which I need to add 4 columns onto the end of, the data for which comes from 4 tables linked to it. Below is how they are linked.
Main table------> Table 1 Main table------> Table 2 Main table------> Table 3 Main table------> Table 4
All 4 relationships have a join type of 2 (Include ALL records from 'Main table' and only those records from 'Table1/2/3/4' where the joined fields are equal)
However, 3 of them pull back the correct data when I refresh the Main table, but the 4th one doesn't - which appears to be to be set up in the exact same way. It does bring back data, but it's the wrong data or in the wrong order.
For example, if the related field in the Main table is "Sarah" - It needs to bring back "Programme", but some Sarah's pull through Programme, some are blank and some are another option altogether. Table 4 has no duplicates or typos etc and I've tried deleting it, loading it in again and creating a new relationship but nothing seems to work.
I currently have a front-end/back-end database, but at some point in time one of the tables has been modified and whenever the front end connects it comes up with a parameter request for a field that no longer exists. I have narrowed it down to MSysQueries, where there is a reference to this field. Is there anyway I can avoid this or change/repair the system table?
Thanks for all your help on my last post, again have a problem to update the application, Everything works well but then I need toadd an extra table on my app. At first I thought I can add a table on my Back-End but when I open the Front-End it wont update.
Can someone out there help me how to add a table on apps. from the ground up?
i have 4 supplier tables with identical field names but different databases in sql.I want to have them all in one table and only want the information for reference i do not want to edit any of the data.I need to create a new primary key number for the complete table. The data will need to be refreshed as the data comes from MMS Sage looking at company PLsuppliers.
I have tried a linked SQL union view- but this has no primary key.I need to keep the Primary key consistent as the data saved in other tables will use this field.The overall goal is creating a Purchase order system and this list will be my complete supplier list.
I have a split database. My backend Relationships aren't updating to my front end. How do I get my front end relationships to update to what my back end looks like? All tables are LINKED not imported.
I have a frontend and a backend database. As usual i keep the tables in the backend. Now I have some tables which need to be emptied and then refilled. I empty the table using the code
Code: DoCmd.RunSQL "DELETE * FROM TransNMTbl;"
then I fill in the table using
Code: DoCmd.RunSQL "INSERT INTO TransNMTbl SELECT * FROM TransTbl;"
The code runs fine. The problem is that the linked table is not used and the sql statement creates another TransNMTbl table in the front end and puts the data there. Bu I need the table to be in backend.
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 work in an office with Office2000. One branch of our non-profit organisation had a volunteer design a database in Access to track the usage of rented storage bins.The database works great for its intended purpose, however the volunteer is not available and the front-end is so locked down that I can't get into the table structure to run some usage queries I need for my own job, which is Resource Development (donations).
I don't know what to say to give more info, because the computer is a stand-alone in a different department detached from the network, so I have to physically go to the other end of the building & work in it, I can't get screencaps etc easily, and most of the menus have been disabled so it doesn't even give me the info about the version of Access etc.
Can i make an html of login form, whose data is saved in access as back end. I am curious to know. but of course simultaneous saving is considered yes in here...
How to secure SQL data when my MS Access database must access it using linked tables. Generally speaking on the Internet, assertions that migrating to SQL is more "secure" are rampant; explanations of just how that is are scarce.
Sure I can restrict access and put different roles on different tables, then put different people in those roles, but that doesn't really do me any good. Ultimately I want to achieve the following: Allow them to do all kinds of stuff (including Update, Delete, Insert) using my access application, but I would NOT want them to have those same rights if they installed SQL Server Management Studio, or for that matter, simply created an ODBC connection using another access or excel application.
In other words, ideally, I'd like to have SQL server view my Access application as a user in its own right. Not sure if that type of impersonation or identity is possible to achieve.
I understand that any data that is inputted into a form is always transferred back to the table in question.
In the form I created, I had
4 subheading scores added together to form another subheading named function =([1]+[2]+[3]+[4])/4 was the formula that I put into the control source. The calculation worked fine on the form giving me the correct name. However, this number did not transfer back to the table simple being labelled as zero. Can someone please advice!
I'm trying to perform a massive data dump. I have about 1,000 records that need to be added into my database. This is coming off an Excel spreadsheet.
I don't know if this is possible: I have a table, tblTorders, which is linked to the table, tblItems. When I open the tblTorders, I can click on the plus sign to expand and see the related data in tblItems.
How can I import data to populate the fields in both of these tables? I can't use the import function because you can only select to import it into one table.
Do I do it through a query.... I'm not sure where to go on this one.
I have 2 linked tables, I would like to join these tables in access, however the first table's field is a memo and the second table is a number. I have tried to cint() the field in a query but I get an error message "Explicit conversion from datatype text to smallint is not allowed"
I have a table in MS Access 2010 that is a link to an external data file in .csv format. I assumed that it was not possible to append data to a linked table until recently. I appended 3 records to the linked table and discovered that the 3 records were appended to the table and the external data file it was linked to.
I have a database consisting of three linked tables, with ID as unique identifier (primary key).
I would have expected the data type for my unique identifier, especially in the main table, to be Autonumber. However, I discovered with some surprise that the primary key (ID) in
Table 1 (Main table) is data type: number, field size: double
whereas in table 2 and table 3 the ID is data type: autonumber (field size: long integer)
It must have happend "SOMEHOW" when I divided the original single table.
Is this as it should be? Or could it lead to trouble later on?
If not as should be, is there anything I can do right now to rectify the situation with risking upsetting the relationships and all?
What precautions should I take, apart from taking a backup?
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 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 am having the problem of importing a database from Excel/Msaccess 2000 to a Msaccess 2000 database from which the data was originally exported. The Database consists of two tables connected in a querry and the two tables has a unique primary key thru which the two tables are linked using a querry. While importing only two tables are listed in the importing wizard and not the querry.
So how to import the data to the two tables connected by a querry using a primary unique key.
I'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.
I'm trying to set up a saved import, but keep getting the following error message: "You cannot record your changes because a value entered violates the settings defined for this table or list (for example, a value is less than the minimum or greater than the maximum). Correct the error and try again"
There are a couple hundred fields, and they are all set to text. Is there a way to figure out where the problem is occurring without going through all fields?
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 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.
