General :: Merge All Data To Identical Central Database
Jan 20, 2015
I have started working on an existing MS access application (Front-end & Back-end) built with VBA. The frontend linked to a back-end access database which contains only tables. Because of the nature of the work involving vehicles. Each user has their own copy of identical databases with their individual data stored in backend.
Right now we just copy each back-end database via ftp and store it as usr_backenddb_date.accdb Back end databases contain around 16 tables with most of them containing a autonumber field as a primary key. Further tables are connected with each other referencing the primary key as a foreign key .
I would like ideally create a function in vba that lets me select the database and merge all the data from that database to a identical central database. For the initial part, I am thinking of combining each individual table in each database and changing the autonumber field with SQL with possibly trying to cascade the change so the refrences remain intact.
Constant Access to one back end db via internet (or server) is not really possible as the users are able to connect to internet (network) only few times a day. There are over 100 backends (for each vehicle) with over 1000 records in each.
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 designed a touchscreen input system using Visual Basic.net and this writes to an Access Database. Each Touchscreen has its database locally so it can still work even if there are Network problems.
Now what I would like to do is have all these local databases write to a central database say every minute but only write new records to the central database. The Central Database can either be Access or SQL.
I want to be able to store 2 identical fields on the same table in the database. The copy will start off being the same as that input in the original field. 90% of the time the 2 fields will always be identical but the copy may be changed at a later stage. I looked into using the copy as a calculated field but found out these can not be updated. Is there another control I can use or do I have to code the population of the 2nd field specifically (in AFTER UPDATE EVENT?) myself. The added complication is that the original and copy must be selected from a combo box as all values are held in a separate table.
Also trying to make the second field = to the first field in the design stage of the table using default value
SO if I put default value = [table].[fieldname] I get an error stating could not find field 'table].[fieldname', and yes the opening and closing square brackets are missing from the error.
I have a problem and wander if anyone knows a solution?
I have a central database that runs on a stand alone machine (soon to run on a server with VPN connection), it has a form that enables us to report faults this works fine however i would like to be able to send the form out to our operators (all over the world) for them to fill in when needed. then what we would like is for them to send it back to usand then for us to upload it to the central database.
I have created a rather large data entry form for one of our departments which will be used to run a mail merge document. The merge is run off of a query of the form, rather than the tables themselves...I think that is what I've read is the right thing to do?
Anyways, most of it is working great so far but I've run into an issue where a few of the form fields are combo boxes. In access and in the query the data looks correct, but when you look at it in word (in edit recipient list) and after the merge, it will have a file path name instead.
So a combo box that has "Medical Plans and Visual Plans" in that field in the query, comes over saying "c:Users ameAppData
Ex: New Hires are provided information about Medical Plans and Visual Plans. Ex: New Hires are provided information about MeC:UsersbrooksAppData
It always shows the first two letters before putting the filepath name in there.
I have tried doing it multiple ways...a lookup to another table, lookup right in the field itself....get the same results.
I want to be able to merge the two records together if the field chr matches between the two files plus if there is an overlap between the start number and end number from each file. For instance the first record from each file would match because the range from 1000 to 2000 of file 1 has numbers consisting of 500 numbers (1500-2000) that are also present and overlap in file 2 (1500-3000). I possibly cannot use < or > since the ranges from each file will vary to different degrees. Perhaps there is a between function that might work...
I have a question regarding making a query with joint data that are not identical, as I'm not sure whether it's possible.
I have to look at certain serum levels at te start of a new medication regimen, and serum levels after 5 years.
I have one database with:
Patient number Start date medication Start date medication + 5 years And one database with:Patient number Date of blood test Serum level molecule A Serum level molecule B
What I want to do is make a query where the patient numbers are joined. The problem is that the "start date of the medication" and the "start date + 5 years" are not identical to the dates of the blood tests. E.g.: I have a patient that started medication on 01/March/2006, but he has had blood tests done every 3 months from 28/November/2003 till now, and not on 01/March/2006.
I would need the results of the blood tests (of molecule A and B) at the start of the medication and after 5 years, but if the test date differs by a day, Access already sees they're not identical.
I would like to have access select a blood test date that is as close to the medication start date as possible, within a time frame of e.g. +3 and -3 months. Is this at all possible?
I often create contract using mail merge. I have an access file that I want to use as data source for word file. But it does not automatically.
Please download the attached file !
If there are 1 customer and 1 property, I do not need to do anything. Conversely, if there are many customers and many properties, I take time to manipulate.
Firstly, I open the word file. I have to copy and paste paragraphs that I want. Highlight of the original paragraphs is blue.
Secondly, I click 'Insert Word Field' -> select 'Next Record'.
In short, I wish to use VBA in access file to automatically perform the steps that I have outlined.
I have searched the forum and have found a lot of information however I am not sure just exactly what I am looking for.
Here is my situation.
It is a spilt DB.
I have a database with a form and a subform. The Primary Key in the form is unique to company A ie ID=CompanyA-1, CompanyA-2, and so on. There is a one to many relationship to the subform.
I have three of these databases in use, all identical execpt the Primary Keys. one is CompanyA, the others are CompanyB and CompanyC.
At the end of the month I want all companies, A,B,&C to send me their Backends so I can bring them all together into one database. The master database I want to bring all three backends into has the same Front End as the other three databases.
My question is what is the best way to bring all of the data together in one database so I can use the common front end to view it.
I am assuming that since the PK for each database is different they should all cometogether without much of a problem? If I can figure out how to merge them.
I'm trying to create an archiving routine as my database is becoming very large. For about 10 tables I want to shift certain records to an external database which would have the required 10 tables with the same table names and structure.
So far so good. I now want to automate everything using vba. I can see how to use the INSERT INTO statement but I don't want to have to name every field as there are hundreds. I just can't see how to do this.
If the table structures are identical how do I neatly shift a bunch of records from one to the other using code.
I have two identical Access tables, for example tblDataYesterday and tblDataToday. The data from tblDataToday has updated data changes in it that are different from tblDataYesterday. I have a maximum of 100 fields to review. I want to compare the two tables and display in a query the differences between the data from both tables.
...TableA: 1 indexed field "Name" and many data fields in ~ 1000 records ...TableB: 1 indexed field "Name" and 2 data fields (DataB1 and DataB2) in about ~ 50 records
Tables currently have NO relationship set.
Want to add TableB data fields to TableA if Name are identical.
DataB1 and DataB2 fields are Not currently in TableA but could be added very easily.
Update (or whatever) will be done weekly where all previous data for DataB1 and DataB2 will be cleared from TableA before job is run.
Hi i have database which is on a network and gets run of the network is there away of autosaving on the clients machine so it update the one on the network when the network comes back online. Is there a install program as its used by 15 people to work at same time but no database server is on the network
Can some on explain to me what I need to install and how to send a personalized mail merge from Access. I would like to use the names and email addresses from my database to send individual emails to everyone in it. Where do I find the proper add on? Thanks alot. Alex
I need to merge data from one DB into another.I have a split database with front end DBcompanyFE and back end DBcompanyBE. BE is on the server so users at company (3 users) can access it with their own FEs.I also have 2 users that are working at some other location (geographically) and they have identical BE of database (DBcompanyBE) and their own FEs.Now, my problem is, that at each location there is different data entered, but on both locations all the data is needed. What would be the easiest and mybe most automated way to merge/combain those data.
I recently designed a new database according an old database in order to replace it. I found that I have trouble transferring the data from old to new database.
Only transferring data from one table to another
Database A: [table]![customer] to Database B: [table]![Client]
I have read only access to a database maintained by a vendor. I am using an append query to search for new records in that database every time my database opens through a macro. This adds any new records to my table. I then add additional information to each record in my table. This is newly acquired information, not calculated, and it is different for each record.
My question is can I keep my table up to date with the vendor table without running the append query macro at open every time as my database may remain open for extended periods of time during updating of records.
I have to design 2 databases base on some data that was given by my instructor but I feel like I'm missing something on both specially the 2nd database. I have attached my work so far as well as the instructions and the existing data..
Is it possible for a website to pull data from an Access database?
We have all our department's policies in a MS Access database on our server. Some of these policies need to be made available to the public on our website. I'm wondering if there's a way for the website to pull directly from the database rather than having to manually upload the policies to the site every time they change (annually, semi-annually).
I've used MS Access a fair bit in the past but am somewhat lost since moving to 2013Pro.Some years back I was using software to document radio intercepts, this was based on Access but used a program to display and enter the data.That program was lost after upgrading to a new computer (tied to the CPU) .And the company has long since gone out of business.So I am left with the MS Access elements.In the form of a 3mb database that has nothing but a long list of tables to show for itself.Each table opens and has some ID columns with text like this in them 'L096e0dd24757c 1533a7cc1 53e 6ba44 bd' and after has usable data. What I want to do is set up Access so I can use as much of the data as possible.
