Hello.
When linking a table via ODBC I usually get asked to pick a field that contains unique values.
This is all very well but I have hundreds of tables to link to across a slow network and would like to leave it running for a few hours.
With the current set up, this is not possible and I have to keep clicking on ok every few seconds/minutes.
Is there anyway to avoid this message so I can just leave it running until it finishes.
Regards.
Hi all,
I am a newbie to the forum and dont know much about it yet so please point me in the right direction if i am doing anything wrong..
My task is to create a spreadsheet that will automaticaly update on opening. The data i require is in Sage Line100 which is very difficult to work with(for me with limited database knowledge).
Because i need to link tables i thought that the best way would be to create a link with Access and create the report format that i need so that it could be exported to Excel.
1: Is this possible(or am in dreamland)
2: How do i refresh the data or is it possible to make it dynamic
3: how do i create a report that saves as an excel file and refreshes when opened
Thank you for any help that can be provided(bowing down to superior knowledge)

I'm nearly at the point of distributing my database. I have been writing this on my laptop and I need to get it working on a Terminal Server and Data Server at the data centre that host our system which is a remote location. The Terminal Server has Access Runtime only, not the full version of Access. This obviously presents me with a bit of a quandary as I still need to be able to maintain the software but do not want my laptop to link via the web to the database to do so. My solution is to take a copy of the database onto my laptop when I need to do anything, which is not a problem. My issue is that I'd like a simple way of maintaining the link between the Front end and the Back end so that if I upload a new copy of the back end or the front-end it will not throw the toys out the pram at the users!
I understand that I am best to put the back end onto the data server and to then distribute the front end to each user. Each user has their own account on the Terminal Server so I can put the front end into their userprofile or something similar (if it is true that I can't just give them all shortcuts to the same front-end that is?!).
I would like to try and get the back end to link to the front end via ODBC as if this is the case I can use the File DNS path on the terminal Server so each user has access and can use File DNS on my laptop when I need to do any updates on my copy so that I am not having to do anything too complicated with the linking of the front and back end due to the differing file systems. Is this possible to do or am I completely going at this the wrong way and missing an easier method?
I am looking to automate the process of linking my Access DB with an ODBC connection to an SQL DB with VBA (unless there's an easier way to do it?) - some sample code - if this is possible at all?

For example:
We use Hotmail to see our mails. but we never download the complete database.
So is there a method that we can secure the backend using roaming profiles or something else so the user has a link to the backend but cant directly access the backend.
I am currently using Microsoft Access 2010 32bit, and have one database acting as parent, with a second linked database as a client for people to work with, and the parent database has tables imported from Sage V21 via ODBC. I have used the following code as specified in other examples as follows:
Code:
DoCmd.TransferDatabase acImport, "ODBC Database", "ODBC;DSN=MyDNSMachineName;UID=MyUID;PWD=MyPassword;LANGUAGE=us_english;" & "DATABASE=pubs", acTable, "INVOICE", "INVOICE"
one of the tables has 10k records in it, it only transfers 77 records. After manually attempting an import via the ODBC wizard it finally lets me access all 10k records.I wish to have a single button click delete and import fresh tables without worrying if all the data is coming across.Also, when manually adding a table, I am usually asked by the wizard to specify an index, but with the code above, I am not offered that option and the tables come across with no index. I am led to believe that having tables that link to each other without an index is bad, so how do I ensure an index is created?
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.

Dim tdf As TableDef
For Each tdf In CurrentDb.TableDefs
If Len(tdf.Connect) > 0 Then

End If

How to Update ODBC linked tables on ms access?
View 5 Replies View RelatedHello, this is my first post (anywhere ever)!:eek:
While I have lots of Access programming experience over the years I have broken new ground this week and am in unchartered territory and need help please!
In the organization I am working for (as Procurement Manger), we use AMMS (by Microwest) for work order generation and inventory management, etc. I have been able to import into Access the tables of interest from this SQL-based package. The problem is that I need to share the tables (via nice front end forms/queries) with about 20-30 people in the field.
I don't know much about ODBC but the administrator of AMMS was kind enough to give me access to the AMMS database tables via ODBC and I, personally have access to read the table data but none of the other people in the field can access these tables due to security rights.
So, what I have done is I created MS Access tables for each of the 4 AMMS tables of interest and I run code that runs delete and append queries on each table. I then have a separate public db that the field people access with all the queries and forms but only links to the Master db containing the 4 Access tables derived from the ODBC tables. This works ok but there are issues:
1) if any field people are on the Public db, the code to import the ODBC table data loops and does not complete the delete/append cycle on one or more of the tables. I can only refresh the table data when nobody is connected to the db - impractical.:(
2) the ODBC tables are rather large - one is over 38,000 records and it takes several minutes to run the delete/append queries.:mad:
3) When I created the Master db it was some 83MB. After running the delete/append queries it is some 179MB and appears to increase in size every time I run the delete/append code. When I run "compact db" it stops running after a short time. Does nothing but create a new file (db1.mdb) of the same huge size as the Master.:confused:
I suspect the most graceful solution would be to give each user rights to the ODBC tables from AMMS in Access. In this case, I wouldn't have to run delete/append queries and the data would always be in relative real time subject to the refresh timer. Unfortunately, due to AMMS licensing restrictions, this is not doable.
I have tried to search the internet for guidance but no luck. This forum appears to be an excellent opportunity to get expert advice on this particular issue. I thank you for your thoughts and guidance.
I wonder if anyone had any suggestions regarding how to link 4 ODBC tables so the info in each of the 4 ODBC tables are in one table. The 4 ODBC tables are linked in from a mapping system. Each table has 80% the same fields with some minor differences. i dont know if a union query would be the best answer in this case as the field in each of the ODBC's tables do not exactly match. Some have 12 fields, some have 14 fields. Any help would be appreciated?
also this would be using Access 2003 if you would like to know. thanks
My problem is best explained by example;
In Access Database A, I have some linked ODBC tables (to an SQL Server database) and some local tables.
In Access Database B, I have a front end which links to all the tables in Access Database A.
The problem is, when I try to link the tables in B, I cannot see the ODBC tables linked in A. Is there any reason why not? 'Why not link Access Database B to the SQL Server tables directly?', you may ask. Well, there is an answer to that but it is quite difficult to explain. I assure you there is one. :p
Hi,
I want to import into an MDB table a csv file.
I'm trying to use the bulk copy table.
my function is:
SQL = "SELECT * INTO [my_table] FROM [ODBC;Driver=Micrsoft text driver (*.txt; *csv) ;Dbq=c:\;Extensions=asc,csv,tab,txt;].table.csv"
db.OpenEx( "Driver=Microsoft Access Driver .mdb);DBQ=c:\access.mdb;", CDatabase::noOdbcDialog );
db.ExecuteSQL( SQL );
when i run this function i get an error : "You cannot use ODBC to import from, export to, or link an external Microsoft Jet or ISAM database table to your database"
when i try to import in the same way a dbf file (insted the csv file) with VFP it's working well.
what seems to be the problem? how can i fix it? or if some one know how can i import a large csv file into access DB in an efficient diffrent way?
thanks ishay
I have big problem with connection between ODBC and Access 2007. Everything is linked correctly but I have problem with separator in decimal field. In my country this separator is "," not ".". I found information about connection in MSysObjects.connect table that
Code:
...;BTD=F;BNF=F;BAM=IfAllSuccessful;NUM=NLS;DPM=F;MTS=T;...
I found somewhere that I need to change NUM value from NLS (default) to MS. Do you know how to edit this value? For example Access 2007 see value "123.8" (so it is in my country "123,8" ) like "1238"
Hi!
I'll cut right down to it: I have an ODBC connection to a (SQL Server) test database on my development machine that is identical to the live database to which a (different) ODBC connection exists on the PC where this Access application is to be deployed. The problem is that when I deploy, there are some tables that have to be updates, because they still point to my test database. The other tables look like they use the default database for that user.
I used to be able to just copy the Access application and it would work without having to update any linked tables.
To clarify, the tables that work without a problem look like this in the Linked Table Manager:
t_mytable (DSN=odbc;)
And the problem tables have this:
t_mytable2 (DSN=odbc;DATABASE=my_test_db)
I don't seem to be able to clear that DATABASE= thing up. Can anybody tell me how this works?
If this question is overly trivial, I apologize.
Hi,
I have a lot data to append to ODBC linked table in MS Access. I want to know that which way is faster to append the records.
if I append the data into ODBC linked table,
1) create the one query (append) to insert the records into ODBC linked table
2) use the VBA code (DAO/ADO) to insert the records into ODBC linked table
which way is rather faster?
My tables are sybase linked tables to my Access front end. I get this error whenever i click away from my mainform while my not-null fields (textboxes) have not been entered. So, i would like to put an error message "somewhere" that tells the user to fill in the necessary fields and highlight the necessary textboxes in red, instead of this scary ODBC message

Where do i put this message? or should be question be, "what the proper way to handle this intimidating error? :)

I Created a form and linked it to a ODBC table with no data. Set the Allow Additions property to Yes. It shows fine if there is data in the table but not when there is no data.
View 1 Replies View RelatedI have 2 identical database in terms of structure but it differs in data.
Basically I would like to import data from subDatabase to mainDatabase and ensuring that there are no duplicate records.
I have used the "link to datasource method" through importing the tables to have the "updating" function.
However, this method also means that the records in mainDatabase are also imported over to subDatabase which I do not want.
Is there a method to ensure that the records are shared/update one way only? (i.e. import from subDatabase to mainDatabase and not main to sub?)
Currently trying to build a database for customer management and order placement/tracking. Want to set a couple of rules so that if I for instance click yes of billing and shipping address the same that the database will automatically fill the shipping address with the data I inputted for the billing address in the same table.
The other issue I can see I'll run into is, I want to be able to select one of the company ID's (made up of a three letter abbreviation of the full company name) in the product ordering table and it will automatically fill in the rest of the customer data (phone, email, address etc) data into that form.
I am doing a project where we are collecting home owner data and information on all the dogs in the household. The data for homeowner has an autonumber primary key because no field is unique or has been consistently collected. I am struggling to link the data for the dogs to the owners because an autonumber primary key will not work since not all homes have dogs. I need to have this set up so that people who are not tech savvy can look up each homeowner (or dog) and get the dog (or home owner) information. And to make things even more fun we need up to 15 potential dogs per household each of whom will have 18 different pieces of data collected.
It looks a little like this (and you can see my not matching ID issue):
Homeowner table
ID First Name Last Name...........Total Dogs
1 Max Maximus 5
2 Min Minimus 0
3 Mus Musculus 1
Dogs 1-5 table
ID Date Dog 1 Name Dog 2 Name .......Dog 5 Name
1 (Max's) 4/11/14 Bobby Billy Betty
2 (Mus's) 4/11/14 Jojo
Min will have no dog records at all, just home information.how to link the dog's to the homeowners .
Hi Folks.
I'm having a problem with ODBC in Access.
For some unknown reason, when I click Get External Data > Link Tables
the ODBC Dialog box doesn't appear.
I have reinstalled Access and ODBC from the MDAC.
Still the ODBC dialog will not appear.
The funny thing is that existing links to my SQL Server database open fine and display the data.
Has anyone experienced this issue and what was the fix.
Thanks.
I am working on an MSACCESS database that reads data from SQL Server through ODBC Connection.
I have multiple tables that I have linked in and created Queries that read the data and created Make Table query.
However, I am asking if there's a way to bring the data through a query that doesn't need the linked tables. Is there a way to bring different fields from different tables into one query without needing to import all the tables, since the tables have many fields that I don't need.
For example in MS Excel, I am able to do that, a query that will bring external data from SQL Server from different tables and only brings the fields that I need for my report.
Our master database has linked tables with ODBC to our SQL database and linked tables to another access database. On the computer i'm running this from a System DSN data source has been created to connect to our SQL database.
The problem I'm having is when I run Macros to kick off Queries, there seems to be some kind of timeout issue and its not consistant. Sometimes in Access after a hour or two, the ODBC links somehow just fails. I have to go up to the menu and go to 'Get External Data' and then 'Link Tables' and relink the ODBC DSN connection. I make sure to hit save password and the end but that doesn't seem to do much. This also happens sometimes when I close and reopen the database.
But it seems erratic, sometimes it can stay up for hours but sometimes just a few mins. Sometimes I can close the Access database and reopen without losing connection. Being so erratic, this makes it very hard for me to run batch files nightly to kick off Macros. Is there some kind of inactivty timer for DSNs? Or maybe with the SQL database itself? Or is the way i'm restablishing the ODBC connection wrong ?
I have Linked a few ODBC Databases to my database in the Tables objects. How do I make them usable for queries or as record source for my form? I tried to create a query but the ODBC databases do not show up in the Table options.
View 14 Replies View RelatedUsing access 2007 (and tried 2003) I have a linked ODBC table which is using an ORACLE driver. If I query the table directly through ORACLE/SQL for a particular 'job number' I get the following results:

As you can see it only displays the MAX date/time and associated data from the 4 available records, duplicating the record. I've checked the field formats and they all look fine. It does the same if I pull through the table on it's own or with other linked tables.
I have been asked to design a database to replace our old excel sheet to log one of our customers server builds. It a four noded system and i require a seperate log for each node serial models of parts etc, qa checks.
I intitial started by just using one table but forgot the limit was 255 rows, i need about 600 - 700. So my plan is now to transfer to indivial table for each node. Then, a general table named Main for all my other details.
Although this seems simple, i now have the annoying task of being able to link them all together and produce a single PDF file to send to our customer whilst only entering our system serial number once to produce this.
My basic understanding will be to create a System Serial Number field in each table a link it via relationships, but if i produce a report with everything i need would it input my details for all four nodes? If so how would i set this up?
I will be splitting the database once completed and then making a ACCDE file for my techs to use.
