How To Control Multiple Databases From One 'master' Database?
Aug 31, 2007
Hi all, i hope this is posted in the right place first of all :) apologies if not..
I have about 8 individual databases which will be used simultaneously by users. I wish to be able to have full control over these databases from a 'master database' including being able to delete the data in there (possibly import fresh data but not 100% needed) and export data to be analysed in Excel etc
I figure this can be done with access but if i'm on the totally wrong track i would be appreciative if someone could give me a push in the right direction..
If any more infomation is needed then let me know.
Thanks :)

I have database for each location. Every location will update some information in the databases and send it back to me. In those location based databases, information will be stored in one table called "consolidate_input". I will store these databases in one specific directory and then I want to accommodate the data of "consolidate_input" into one master database having the same identical table in the database.

I have a large database of Purchase Orders
Orders can be placed by people in one of 4 departments
I would like to automatically make 4 separate databases (so each department can access their own) from the master
Is there a way to do this?

I have one Master database and multiple child databases in a folder. Each of these databases (both Parent and Child) have identical table called "source". I need a VBA code which will consolidate tables of child database into the Parent database table.

I am using Access 2003. I have developed a split (front and back ends), replicable database. As I make changes to the design master, I want to either keep old copies of the design master or ideally, maintain the design master under source code control (e.g.:CVS). This would allow me to be able to retrieve older versions of the database. The problem occurs what I make a copy of the design master, or when I try to pull out of my source code control system (CVS) an older version of the design master. When I open any of these copies, Access thinks this database is a replica and will not let me make any changes to the design.
Is there a way around this problem?
Or am I trying to do something in Access that does not make sense?
Thank you for the help.

My bound master form has bound subform in it and both of them has linked fields. In the master form i've placed a checkbox which if unchacked will lock and disable a textbox in the SUBFORM, and if checked will enable and unlock the textbox and fill it with a calculation result, which will then be passed on to the underlying table.
Now, suppose in the master form (named X), i have A (checkbox) and B (textbox with numeric value) and in the subform (named Y), i have C & D (both textboxes with numeric values). Hence if A is checked, I'd like D to return the result of - "B*C". Or else D will remain locked and disabled.

I have a series of 7 separate Access 2010 programs that are designed to run under the control of a scheduler, and they must always finish. Errors are trapped and logged but mustn't stop the processes completing.
What I'm trying to do now is to create a single master control program that runs each individual application, one after the other, in order. And each individual app cannot start until the previous one is finished.how to call a separate Access program and know when it has finished.

I have been running 5 reports to gather company information. I then take the data from these 5 reports and manually load them into an Excel spreadsheet to calculate a grand total. I would like to be able to run a query or report within my database to get the same information. I have attached a copy of my spreadsheet for review.
Could someone please review this spreadsheet and help me design an easier method of calculating a grand total.

I try to call one database forms and tables into another database without creating tables and forms.
Database where (target) i need to open forms and tables:
insurance.mdb (In the same database I click on TOOLS - REFERENCES and add accountreceivable.mdb as i need all forms and table from that database)
Database from where (source) i need forms and tables

I try to call forms and tables from accountreceivable.mdb into insurance.mdb. Do i use the below function in insurance database to open tables and forms from 2nd database. If i do where should i write this function i mean in the module of insurance database or in the module of accountreceivable database. How to i call that function
Function OpenForm(byref vformname as string) as boolean

We're a small shop building a modest database to keep track of our product listings on eBay. Two people on non networked computers are doing the data entry into cloned copies of our database. This includes attached photos for each record. At the end of each week, we want to combine the records created separately into the master database on my system.
It seems like it would be simple enough to just cut and the paste the records from the two databases into the identical master. The problem I'm anticipating concerns the attached photos.
Some strategies are to transfer the records from the data entry computers to the master database while keeping the attached photos intact.
Is there an effective, efficient way to set this up or would it be best to use the OLE format for the pictures instead of attaching them (which I prefer)?

Hi Folks,
Hoping someone may be able to point me in the right direction.
I've got several databases used for different tasks, in which I just added an hyperlink to them from a front end database. All my team could access any of the data bases at once. It was using the WINNT/MS OFFICE mdw file.
Since my last question, I've now managed to set up a MS Workgroup Administrator file, which is on a shared drive. Everyone has joined this workgroup, and when people logon it now greets them with their name and records their name against any tasks. Thanks to everyone for their help with setting this up.
But since I created this new workgroup, we can't access more than one database at at time. It comes up saying 'mdw file is in use'. However, one person in the office can. I've looked at all the setups for individuals, and can't see any difference between ours & this one individual.
Am I missing something obvious ?
Cheers
Karen

Ok, this is only a very general question, but I'm hoping somebody here can give me some general advice.
Basically, I have three separate database which I've written for my company. They were all written at different times, hence the fact there are three and not one that does three things. The first is used to raise, edit, delete, and track RMA records for returned merchandise. The second is used to raise, edit, and track Training data for people who have undergone my training course. The third is my main database that contains all of my clients' details, plus a log of all calls taken from them. This is the largest and most complex of the databases and has some fairly advanced relationships setup to enabled hundreds of call logs to be linked to a single record of necessary.
Now all three databases have been written using the same kind of structure. They all use popup modal forms to prevent malicious/accidental damage to the database by the staff who use them. They are all locked down and Access cannot be broken into whilst they are running. they all also have their own primary keys.
All these databases work just fine, but I'm now a little tired of each staff member having three shortcuts on their desktops, depending on which database they need to use. what I'd really like to do is somehow merge all three of these databases into one single database, and alter the switchboard accordingly to allow users to access any of the three parts of it.
The problems - as I see them - are: (a) that my main database uses a lot of relationship links to maintain certain records, whilst the other two use none, and, (b) that each database, having been written separately, has records with their own ID keys and autonumbers.
I did toy with the idea of having some kind of function on my main switchboard that would allow me to close the current database being used and open another, all without closing Access, but I haven't been too successful in my tests...
...so, my question is, does anybody have any bright ideas as to how I can go about merging these three, or, at very least, centralising access to all three?

I'm hoping someone out there can help me out with a problem. I work for a company that creates websites for car dealerships. The process involves me inputing data to a standalone program which creates a database for each dealer. When I upload the information, the program I use creates an inventory.mdb which is accessed through the asp pages I have.
examples of finished product are:
http://maconsales.com/freedom/inventory.asp
http://maconsales.com/freedomnew/inventory.asp
We currently host about 13 dealers. What my boss is wanting me to do, and I'm having problems doing, is making it possible for someone online to visit our main site and view all inventory from all dealers without having to leave our site to look at each individual inventory. And I would like to do it without having to manually create a central database with all the inventory we have, about 1400 vehicles.
Is what I'm trying even possible? or am I looking at a long night of data entry?
Any help would be appreciated.
Thanks in advance

Access 2003
I've inherited an Access Application which has
(1) a number of linked tables that are used to seed the underlying SQL Server database.
This system has been set up and is working in Development. My task is to move it to UAT but with regards to point (1) above I can't see any alternative but to copy the Access Database, create a new System DSN and re-import the External Data from the new DSN. What I'd like to do is use the same Access Database to point towards DEV or UAT or PRD. Is this possible to do this or am I stuck with maintaining 3 different Access Databases ?
I am a developer with many years of experience but my Access knowledge is limited so any pointers would be helpful.

I inherited an interesting problem. I have 3700 tiny MDB files all of which contain the same table (same name, field structure, etc.), but different data. Each database has a slightly different name. It's the result of XML data mining.
I need to combine these 3700 tables from these different databases into one table in one database.
I can't see any way to automate this and as it's a one-time only project I don't know whether it's worth trying to automate it or if I should roll up my sleeves and just start apending tables.
Does anyone have any suggestions?

Hey Access people...
Does anyone know if it is better as a general rule (server performance wise anyway) to connect to a single database with many tables or multiple databases with fewer tables??
In this case I have a small calendar database and large navigation/metadata database -- both are MS Access & connected to the same ASP page.
Can anybody make a recommendation here??
Many Thanks!!

I maintain a simple Access database which about 30 other users have open every day and use it solely as a reference book. It is simply a large reference 'toolbox' with one form and many many sub reports in the form with links to refference guides for my users. Very often I need to add new reports and just new content overall to the database. My current process is to
1) make a copy
2) modify the copy with all my new content
3) Send and email with the file attached telling all 30 users to delete their old database and use this updated version.
Of course we have many issues including:
1) The files are very large in Lotus notes (is there a way to make these files a lot smaller)
2) Seems like a waste to delete and replace an entire database when only 1 or 2 minor links need to be changed every time. Is there a macro or some code I can create that would act as a patch where the 30 users can run the code and it will change hyperlink paths that I needed changed, report content or anything that needs changing.
gets around having all my users copy and replacing their database toolbox on their desktop. We all work out of a shared network drive so I can have them use the database together in a shared drive but its litterally impossible to have every hand out of the database all at once so I can go in and update, it just does not happen so if there is a work around for getting all users out of the DB, it could avoid having to do anything else.

I'm scanning bar codes into the record search box, most of the time it works as it should but occasionally I get multiple "cannot open any more databases" errors. It still finds the product record but the error messages are super annoying. I am sure to clear the memory on the scanner each time before I scan in a new barcode but it doesn't seem to matter. Also sure to only have one or 2 forms open at a time, that doesn't seem to matter either. Most of the time I don't get the errors but when I have to click through like 10+ error messages (all identical). I only have one database open so I'm not sure what it even means. Also I have tried this in 2 different forms and it's the same for both forms. Seems like I get the errors in my initial scan and then after clearing them it seems to work without errors.

I have 10 small databases. At present, I have another database which serves as a platform to launch the 10 databases. I have a graphic for each database and posted an Event Procedure for each graphic to launch the respective database. For example ...
Dim accapp As Access.Application
Set accapp = New Access.Application
accapp.OpenCurrentDatabase ("M:MPFMPF_Mgmt_Info_SystemSignInPlusSignInPlu s.accdb")
accapp.Visible = True
Is this the best way to centrally locate and launch multiple databases or is there are smarter way?

I am trying to form a join between two separate databases. Database 1 has a column (Gene_Name2) that consists of common names of human genes. In this database there is only one name for each gene per field. The other Database 2 has a column (Gene_Name2) that has various names for the same gene in each field. Most genes have been given different names over time. I want to join the databases into a separate query database so that all of the information in Database 1 is retained and only when the name in Database 1 matches one of the names in Database 2 does the row of information get tacked on to the query database. The problem is that in a normal query the text in both Gene_Name columns do not match and the query returns no matches. I have tried Instr and like criteria statements with no luck.
Database 1
Chrom Gene_Name1 Data1
Chr1 ATC XYZ
Chr2 IDH2 ZYZ
Database 2
Gene_Name2 Data2
ATC;ORF34;NM_123 ABC
ORF65;IDH2 IGH
Joined Query
Chrom Gene_Name1 Data1 Gene_Name2 Data2
Chr1 ATC XYZ ATC;ORF34;NM_123 ABC
Chr2 IDH2 ZYZ ORF65;IDH2 IGH

I have broken up by master database, table, into several tables. They all share the same ID values since they came from the master table. So each table that I split off has a unique, matching, identifier, ID, in both the master table and the new table. Plus a previous matching identifier listed immediately below.
Example: Permit the master or main table and Builder a supporting table. There are five tables that I split off and all have an identifier similar to the two listed below.
Permit->ID
Permit->BLD
Builder->ID
Builder->BLD
All my tables have the same ID. But each table also has a identification numbers such as builder BLD, Subdivision SB and inspector INS>
Permit has the BLD, SB and INS
Builder has only one occurrence for each builder in the Permit table. As in the past it was identified by BLD number and now also ID. the use of BLD is from when I used visual dBase. The big difference here is that I have two ways to identify one is ID any other is by BLD, etc. My first thought is to identified by the BLD. I don't know why, but I guess I fear using a single "ID" to identify my various split off tables unique value or BLD.

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.

At the moment I have a field 'Author' which is displayed using a subform. The user can cycle through the many authors that are associated with each record in the main form. However, what I'd like to do is to display each record simultaneously in the same control, and with a little bit of playing around in VB get the form to work out how many Authors there are and display the names in a particular format. I.e.,
Bloggs, Jones & Smith
Hank & Mason
See what I mean? Does anyone know how I might refernce the records. So logically it would be:
lblAuthor = Record1 + "," + Record2 + " & " + Record3.
If that makes sense...Sorry if this is in the forums somewhere...

I'm trying to set up a simple query that links four tables. However, the tables are extremely large, all in excess of 1.5GB each so I had to split the tables up into four separate DBs. I've tried the following with no success:
1) Link the 4 tables in the DB which contains my primary key. This quickly inflates increases the file size above 2GB and won't let me go any further.
2) Build a remote query to connect the four tables. This looked promising until I tried to run the query and it became evident that it only knows to point to the last database source that you specified.
I'm running everything locally on my C drive. The data source are simple text files (1.6 million rows) from the FDA website.
