Split A Table?
Feb 6, 2013
I'm gonna get right into it; here are two tables I have in my database.
tblAccession
-Accession (PK)
-State
-Test Type
tblSamples
-Accession (FK)
-Sample
-Additional
-Cassette
-Tissue Type
-Comments
-Trim initials
-Trim date
-Section initials
-Section Date
-Control (FK from a third table)
For tblSamples, the fields:Accession, Sample, Additional, Cassette is the same for each accession and is entered when an Accession is logged in at the beginning of the process. The rest of the information (Tissue Type, Comments, etc.) is entered when various people completes those steps throughout the testing (fluctuating people and days). Should I have have the fluctuating information (tissue type, comments, etc.) as a separate table? With a one-to-one relationship? Would there be an advantage/disadvantage to splitting tblSamples into two different tables?

In a situation where I imported an excel file with so many columns and split them into two temp tables and they are linked using a key.
the data has a fixed part lets say
Field1....Field2.....Filed3.....Field4...then Field5.....Field6.....Field7....Field8 is the same data range as Field9...Field10...Field11...Field12. I would want to split this data into multiple rows like this
Field 1 Field2 Field3 Field4 Field5 Field6 Field7 Field8
Field 1 Field2 Field3 Field4 Field9 field10 field11 field12 and so own...
What is the best approach?

I am using a Table to store Parameter Values for a Split Multiuser DB. Question I have...Can I have this Table on the Front End while all the others are on th back end? The use for the table is to store parameter values for multiple queries without the user having to reenter the parameters.
I've tested this and it seems to work...but would like to know if there may be complications.
FYI. I am a Novice VBA user.
Thanks,
Felix

Hi all
I was hoping to get a little advice as to my problem. I have a database with many, many reports, forms and queries. I wanted to split the database to secure the tables and important data. So I use the database splitter wizard and ever thing went just fine. So now my database1 looks into database1_be for all tables.
My problem is: my program now runs very slow. The slowest seems to be when I am adding a new record. I can live with the slowness of retrieving an existing record. I do not have a server nor can I afford one at this time, so currently I am running a peer-to-peer network with the database1_be located on one of my computers second hard drive.
Is there something I can do to help speed things up?
Thanks Enviva

Hi there!
I'm currently working on a malformed Access database, not normalized at all.
It only consists of one table and is designed like this:
(table compartment)
#ID#Name#Member1#Member2#Member3#Member4#...#Membe r20#
So all the members are realized by single columns.
I created a new database, consisting of the main table, the "people" table and a relation table, connecting the people with the compartment (n:m relation).
It works great but I have to get the old data into the new tables. The old main table consists of more then 100 columns, and most of them are now hived off by using relations.
Now I'm looking for a smart solution to convert the table.
Do you have any idea? I tried to use a Query, but I couldn't merge two or more columns and put them in a single one on a new table.
Thank you in advance!

So I split my database into a front and back end, now i wanted to add a table to the database. I created the table in the backend but I am not sure how to make it appear in the front end. I am using access 2010. I tried the link table manager but the table I created doesn't appear there.

I'm working on recreating my church's records in access and was originally wanting to take people from the Visitors table and automatically move the to the Members Table (and same with Deceased & Moved), but after some searching found that's not really do able. So now my question is, can I have a master table that has everybody (visitors/members/deceased/moved) and then split that into different tables while keeping the main table (that way I can go into the main table and reassign the person)?

I have an Access 2007 file that is 'split' so the tables are centrally stored on the server.
How do I update one the linked tables stored in the back-end file with a table from another Access file?
If I import the 'new' table it is not 'linked' - it is embedded with the Access file I am working on.
What is the correct way of doing this without corrupting the data?

My boss made a satisfaction database that tracks satisfaction in 2 ways, so we have:
Table
ID
SatisfactionAType
SatisfactionAScore
SatisfactionBType
SatisfactionBScore
I'd like to make a query that would split these into two lines, one for A, one for B and then export it to excel.

I have a table with the folowing structure:
ID(integer)
Value1(Double)
Value2(Double)
I need to split this table in 4 equals parts:
- count of id must be equal or close to equal(ex: 467 split in 3 x 117 and 116) for each part
- the cumulated Value1 and Value2 must be equal or close to equal for each part

Hi All,
I've developed a database that was working fine until I split it to use in a network enviroment. The problem is a make-table query that now make it's table in the front end instead of the back-end. I need to run a make-table query because the query uses a custom function which then causes errors when the query is accessed by a web form that I use.
The only way I thought of getting round it was to create a permanent table in the back-end which is cleared every time and an append query used to populate it.
Anybody any other ideas?
Cheers

I've created several Split forms that have the data input fields in the form with the relevant query datasheet shown below. As you tab through the form fields, the various cells in the datasheet are highlighted and move across the data row (as one would expect!). I want to put a particular field / Column at the start of the datasheet so that it's always available for view, but it seeme that what ever I do the column ends up back at the very far end of the data row!
I've sussed out the "Freeze Fields" facility which will keep the first column visable whichever cell is highlighted across the data row.
The column I want as the first column currently sits at the far end of the data row. So far I have dragged the row to the first column position; I've arranged the Query driving the form so that the column is at the front of the row, both in design view and in datasheet view, but to no avail. Everything I do to put the column at the start of the row in the datasheet shown below the form ends up with it back at the far end of the row the next time I open the form.

My db is split into front-end and back-end. In the f-e's Relationships schematic, I can see the relationships as they were defined at the time when the db was split, complete with the one-to-many symbology.
I can add a new table to the b-e and set its relationship as one-to-many, enforcing referential integrity and cascading as I wish - and the schematic (in the b-e) reflects that.
In the f-e, I can then use the <Get External Data - Access Database> function to link to the new table, and I can add the new table to the relationships diagram in the f-e. I can also drag and drop to link primary and foreign keys (within the f-e), but cannot select one-to-many. I'm OK with that, as I understand that the relationship is within the b-e, and this is just a diagrammatic representation.
But I can see the one-to-many relationships between the tables which existed when the db was split, and I would like to be able to see the new table's relationships in a consistent fashion. Updating the linked tables via the Linked Table Manager does not do the trick.
Surely I don't have to split the database again in order to achieve a consistent diagram - do I ?

I have elected to have tables inserted into my forms. For example on the School Information form, I have the Employees table inserted at the bottom so that it will show the employees that are assigned to that school when it's pulled up.
Before I split my database into a BE/FE situation, I could expand the items in the tables to other related items, but now that option is gone.
Is there any way to get that back with a split database?

I'm having a problem with a database that i had split. While creating teh database, i had it stored on my personal drive at work, but wanted to move it to the shared drive so the data could be stored there. this is to deal with cross site network connectivity issues that we encountered with another database here at work.
When splitting the database, i split it on my personal drive and then dragged the back end to the common drive. I realized my error, but when attempting to correct it, i somehow have two of the same file, and no back end?
I receive the error on the attached document when attempting to access any of the tables or information in either of the files, the "back end" that i placed on teh drive, and the "front end" that i have on my personal drive.
I also tried to relink the tables through the linked table manager, but receive the same error when attempting that.
Is there a way to recover from this? I had backed up my file by making a copy prior to splitting, but somewhere in this process, this became linked to these and is having the same issue. Is there a way to recover the old "unsplit" version? I cannot copy over all of teh tables, etc. because i get the same error as earlier.
I can attach a copy of my database for reference...

I have a table "MansComps" which includes two fields, the "Index" field which contains a number, e.g "5" and the "Tabletype" field which contains a letter e.g "T". i have created a query based on this table, which combines these two fields and displays the result to a third field which I call "Components".
field: Index
1, 2, 3,....
field: Tabletype
T
field: "Component" has to be like this:
T00001, T00002,...
I have managed to combine the fields in my query using the expression:
Component: [Tabletype] & " " & [Index]
but the results appear without the leading zeros, like T1, T2..I have set my Index content to be a number and as a primary key and the Tabletype as a text. I also tried to change the format of Index to "00000" which works for the Index field separately but not for the Component field.Should I do something in the format of the Component field?

I have a client that is using a split database. I am working on an update to the program and need to transfer a table to the backend that has the correct structure and information included in it. My thoughts are to make a one time use program that transfers the table to the backend. I have seen DoCmd.TransferDatabase and DoCmd.CopyObject as possible ways to go.

I have a split form (frmPatient Schedules) that shows me my records in the datasheet view at the bottom section of the form. My records have a field with a checkbox (ckbxHOLD).how can I get the records that don't have their checkbox checked to be copied as new records to a different table (tblHome Visits)?

I have a split database made in Access 2007. Each user gets their own copy of the frontend from a script. I wanted to be able to edit the design view of the backend tables even if people were using the database so I made all the forms use snapshot source and only allowed data updates through VBA macro update queries. Having any form open locks the backend source table from being edited. In fact, I've found that just having a normal snapshot query open causes the message "Either an object bound to table 'whatever' is open or another user has the table open. Do you want to open the table as read-only?"
Is there some way to have a table be the source for a form or query, but still have it designable under most circumstances?
Attempted to late-bind a recordset on form load; result was the same:
Code:
Set rs = CurrentDb.OpenRecordset("Select redacted as ft from tblRedacted ", dbOpenSnapshot, dbReadOnly)
Set Me.Recordset = rs
Set rs = Nothing
