The database for workers works ok from a solitary table, tblEmployees.
I want to make it a relational db.
I’ve incorporated lookup tables. But I’m lost about what to do next – and if it should be divided further.
I’ve studied many tutorials in relationships, but I don’t find one that resembles this one.
Could a relationship expert give advice please? I've included a sample, hoping this will be simplest way for you to understand the challenge.
I have a pretty standard relationship set up, with the following tables:
Customers: A row/Cust ID for each customer
WorkOrders: each customer can have multiple work orders (linked to Customers by CustID, individual ID is WOID)
Jobs: each work order can have multiple job records attached (linked to WorkOrders by WOID, individual ID is JobID).
As far as I can tell, they're fine and all other forms etc work, updating no problem, referrential identity is enforced etc...
Problems: When I go to make a "job allocation" query for subsequent form, I select: Customers, Work Orders and Jobs table (I then filter by location, but
this problem remains unfiltered also). They link up fine. The query isn't nonsensical either - it lets me add new data. BUT instead of showing all the customers and work orders for the location due for the location, it will ONLY display the records that have details in the Jobs table (the lowest in the relationship chain). Basically, If the jobs sections are empty or "unattempted", then NO details AT ALL will show up in the query. Which is a problem, because I want to see ALL the "unattempted" jobs in the area to allocate them, including customer data and work order numbers. I also need to have the jobs table present, so I can allocate a job date, a contractor etc.
I'm not sure what to do. As far as I can see, the set up I have IS very standard tables/relationships-wise. I have to work it out, otherwise I'm going to have to revert to some kind of 'super-table' (like in our old system) - which I am at loathe to do - I don't want to merge Work Orders and Jobs because that means a lot more typing for me.
Would cascade update in the relationships do anything? (it is checked).
I've been away from Access for awhile and I'm just drawing a blank on this one. Any help greatly appreciated. Thank you.
so, I have created a working SQL statement that summarises data from a bunch of different tables (it's a stock monitoring application so it all has to do with levels of stock, numbers of parts processed etc...):
SELECT tblPPIn.BatchID,
tblPartDescriptions.DrawingNumber AS [Drawing Number],
tblOrder.IssueNumber AS [Issue Number],
tblPartDescriptions.Description AS [Description],
tblPPIn.Qty AS [Total Booked In],
IIf(IsNull((SELECT Sum(tblPPProcessed.QtyProcessed) AS SumOfQtyProcessed FROM tblPPProcessed WHERE tblPPProcessed.BatchID = tblPPIn.BatchID;)),'0',(SELECT Sum(tblPPProcessed.QtyProcessed) AS SumOfQtyProcessed FROM tblPPProcessed WHERE tblPPProcessed.BatchID = tblPPIn.BatchID;)) AS [Total Qty Processed],
IIf(IsNull((SELECT Sum(tblPPOut.Qty) As sumofQtyOutPass FROM tblPPOut WHERE tblPPOut.BatchID = tblPPIn.BatchID AND tblPPOut.IQCPass = 'PASS';)),'0',(SELECT Sum(tblPPOut.Qty) As sumofQtyOutPass FROM tblPPOut WHERE tblPPOut.BatchID = tblPPIn.BatchID AND tblPPOut.IQCPass = 'PASS';)) AS [Total Good Parts Taken],
IIf(IsNull((SELECT Sum(tblPPOut.Qty) As sumofQtyOutUninspected FROM tblPPOut WHERE tblPPOut.BatchID = tblPPIn.BatchID AND tblPPOut.IQCPass = 'UNINSPECTED';)),'0',(SELECT Sum(tblPPOut.Qty) As sumofQtyOutUninspected FROM tblPPOut WHERE tblPPOut.BatchID = tblPPIn.BatchID AND tblPPOut.IQCPass = 'UNINSPECTED';)) AS [Total Uninspected Parts Taken],
IIf(IsNull((SELECT Sum(tblPPProcessed.QtyPass) AS SumOfQtyPass FROM tblPPProcessed WHERE tblPPProcessed.BatchID = tblPPIn.BatchID;)),'0',(SELECT Sum(tblPPProcessed.QtyPass) AS SumOfQtyPass FROM tblPPProcessed WHERE tblPPProcessed.BatchID = tblPPIn.BatchID;)) AS [Total Passes],
IIf(IsNull((SELECT Sum(tblPPProcessed.QtyFailEtching) + Sum(tblPPProcessed.QtyFailCutOut) + Sum(tblPPProcessed.QtyFailFlatness) + Sum(tblPPProcessed.QtyFailHandling) + Sum(tblPPProcessed.QtyFailOther) AS SumofFails FROM tblPPProcessed WHERE tblPPProcessed.BatchID = tblPPIn.BatchID;)),'0',((SELECT Sum(tblPPProcessed.QtyFailEtching) + Sum(tblPPProcessed.QtyFailCutOut) + Sum(tblPPProcessed.QtyFailFlatness) + Sum(tblPPProcessed.QtyFailHandling) + Sum(tblPPProcessed.QtyFailOther) AS SumofFails FROM tblPPProcessed WHERE tblPPProcessed.BatchID = tblPPIn.BatchID;))) AS [Total Fails],
[Total Booked In]-[Total Qty Processed]-[Total Uninspected Parts Taken] AS [Total Unprocessed Parts Remaining],
[Total Passes]-[Total Good Parts Taken] AS [Total Good Parts Remaining],
[Total Passes]/[Total Qty Processed] AS [Overall Yield]
FROM tblPPIn INNER JOIN (tblPartDescriptions INNER JOIN tblOrder ON tblPartDescriptions.DrawingNumber = tblOrder.DrawingNumber) ON tblPPIn.BatchID = tblOrder.BatchID
ORDER BY tblPPIn.BatchID ASC;
don't worry about the details, it works as it is above...
now I only want to display data for batches where there are some parts left, so I've tried adding the following WHERE clause:
WHERE ([Total Good Parts Remaining] + [Total Unprocessed Parts Remaining]) <> 0
should work fine, right?
nope, we get the (all too familiar) 'Enter parameter value: Total Good Parts Remaining' (and the same for 'Total Unprocessed Parts Remaining'), despite the fact I have used these aliases in the previous SQL with no problem...
Is there any way around this or do I have to create a big-ass WHERE statement complete with the subqueries I've already used previously?
This is seriously annoying me today... any help would be massively appreciated!
cheers,

Hi,
I am running a query that has this function
MyRoundedValue: Round([Bonus Total],2)
I am trying to round up the value in Bonus Total.
Currently the result shows 5140.602 and I want it to round up and show 5140.61
Is this possible? For the life of me I cannot figure it out..
Thanks

I have a subform on my main form which I can access properties etc without error, but when I try to set the sourceobject property I get an error saying it can find the object '~sq_cfrmAction~sq_csubPlanetItems'
My form is called frmAction
The subform is called subPlanetItems
The code that errors is this;
Me.subPlanetItems.SourceObject = "qryInPlanetNotInWIMS"
The query runs fine so it is not that?
Help please
Hello!
I have a problem regarding using usernames and passwords to restrict access to certain tables/forms/reports etc....
I have read around the forum and various other websites but cant seem to get much relating to exactly what i am wanting to do.
I think i understand the way the access workgroup security works. But does this not just restrict users being able to view the database as read-only or with other certain rights like that? So, firstly would i be able to use this to restrict the database the way i want?
Or is there a way to create a table with names and passwords and create a form at the beginning where the user inputs their details and then according to the details gives/restricts access to parts of the database? Ideally i'd like the startup form to direct them to a different menu according to the user which gives them only the options they are allowed?
Seems a bit of a mouthfull and i sound like a complete newb but i been trying to figure this out all day!!
Thanks
Hi all,
I have been using Excel data in Access either by importing the sheet as a table or directly linking to the sheet with no problems in the past but today I cannot seem to get the data to import in the right way.
The column on the Excel sheet is mainly populated by numbers but some of the values have letters in them. When I discovered this I formatted the column as text and tried to directly link to the sheet but the datatype kept insisting it is number. I then decided to import the sheet as a table and although it comes in as Text instead of seeing the value A1030573 in comes in as 7.1e+009 and this goes for the values that are purely numbers.
Is this a known bug, does anyone have a solution to to this ?
Thanks in advance,
Mitch....
Here's a weird problem I've had develop in the past couple months, before I upgraded to 2007, and now since I upgraded to 2007.
I've had the same Access database since 1997, and just recently upgraded it to Access2007, but as I said the problem occurred before and after the changeover.
I have two servers at the office. Server #1 (where the database is located) has attached to it is a dot matrix printer, used for printing our 4 part invoices/packing lists. I have another server (#2) which has a laser printer attached to it. The laser printer on server #2 is the default printer for all computers in the office. I have a lot of reports in Access where the printer to be used is the default printer. I have a single report in Access where I specified in the page design and layout to use a specific printer - the dot matrix on server #1.
Both servers are always on. Both printers are always on. I can go for weeks and weeks with no issues in printing the invoices. Then suddenly I'll get a
"This document was previously formatted for the printer (printer name) on (server #1), but that printer isn't available. Do you want use the default printer (\server#2laser printer) ?
OK CANCEL SETUP... HELP
It worked fine for 9+ years, and now I am getting this error. No new computers in the last 2 years. No new printer installs in the last 2 years.
I've gone through, uninstalled the printer, reinstalled the printer, both on the server and remote machines, and now I can't even get the report to "remember" that I want it to always print to the dot printer.
Any ideas?
I have a table that has (to simplify things) two fields.
[Patient_No] [ID]
BA4206 1067404
BA4206 1067405
BG1013 1067545
BG1013 1067546
BG1013 1067547
BG1111 1078432
I want to be able to count the number entries where the Patient_No is the same and output the query like this:
[Patient_No] [ID] [COUNT]
BA4206 1067404 1
BA4206 1067405 2
BG1013 1067545 1
BG1013 1067546 2
BG1013 1067547 3
BG1111 1078432 1
Hopefully this is just a simple query but for some reason i cannot get it to work.
Any help is much appreciated.
Thanks in advance
Ok, here is my scenario.
I have several FE's each saving in their own BE. They are all the same but for different areas of our business. Each has around 20-30 users. I recently introduced another form into the FE that has linked tables to another different BE in another folder. Each FE out there with its own BE now has this form and all of the new forms save to the same (one) BE. Ok, got it?
Now, sure its possible to have them all together and I would anticipate someone suggesting this. Its split up to keep sizes down and performance up among other reasons.
In any event, here I am. All of the new form introductions went smoothly without a hitch. The last one however is causing trouble. On submit an e-mail is sent, the user is asked if they want to submit another form, and if yes a new record is created. If no the form is closed.
E-mails are always sent, no problem. The trouble is saving the record. All except one of the different FE's I have out there in different folders save the record into the table just fine. There is one though that does not do this. The mail is sent and the program behaves normally with no errors but the record is not saved. This does not happen to all users of this FE either. There are some users that work fine and the record is saved in the BE yet other users do not save the record. You can see the .ldb appear and disappear. Our IT dept has been through the permissions time and time again and tell me they are ok. The FE and main BE are in one folder while the BE that the new form talks to is in its own folder. Remember, this works fine for several other instances, its just the one that doesn’t save the record.
I did have a chance to see the permissions the other day and it seems a mess to me. They have users in individually, as they were set up initially and the same users are also in there in a group and maybe 2 groups. The permissions look a mess to me… they really do…. but that doesn’t necessarily mean they would not work and can be blamed. I have no control over this part and it drives me nuts!
What I have done...... copied a working FE from another area into the troubled folder. No good. I have removed the new form along with its linked tables and the record is saved. Put the form and linked tables back in and it stops saving again. The code compiles just fine. I have done compact and repairs.
Any thoughts or ideas out there??? If you need more info ask. I understand what I wrote but you might not LOL
I'm sure you've all seen this before - but, it's killing me. It's for a university project which is being demonstrated soon, and I can't get it working consistently!
When pages are loaded, I get the error -
Provider Error - 80004005, Unspecified Error /db/update_select.asp line 33 (line 33 is the connection to the database)
or
Internal Server Error 500 - Page cannot be displayed
And sometimes I get one about "Jet" "Threads", and ODBC stuff.
I'm guessing it's a driver problem, but I have no idea where to go from here! I'm running Windows 2000 Adv. Server, IIS 4 (I think) and my db is access 97 :O (I would have put a newer version on, but the CD-Rom is so old on the PC it won't take 700MB CDs! Argh.)
Any help would be greatly appreciated!

So, basically my database has quite a number of lookup fields in tables as there is much repeated data, each one references to a seperate table with an autonumber field (ID) and a text field (Value)
Currently I have column one (ID) as the bound column in such cases, as this is what the guy who started me on access said to do, and it's fine until I try and export any query with such a field to Excel.
I have found, through experimentation, that setting the 2nd column (Value) as the bound column allows me to export the values rather than numbers, but I don't know if this is a sensible thing to do? (ie, I don't know what other unexpected effects this might have)
Any guidance here would be very welcome, thanks,

Hello,
I have a table exported from excel. I intially imported this in to access to form a list of due dates for services.
Every week I get and e mail with the updated version.
I am trying to figure out how to update the dates in the 1st table with the new weekly ones.
I can't get it to update. Also there may be the addition of new services as well.
Any tips would be grealty recieved.
Many thanks in advance.
Hi there.
I've attached my db in the hope someone can help my head scratching.
I have got a Sales summary table with several other related table. Most notably, a table with the items in the sale and one with the costs. Because each sale might contain many different items and many different costs, I thought seperate tables were the way to go.
All I'm trying to do is make another query that gets the total sales (That's adding each line item * quantity) - (Each cost line item*it's quantity) and then finally the margin made on the deal.
However, if there are no costs or sales involved in the sale the query ignores it. (Sounds odd, but some transactions might be cost free, and some may not involve any revenue - so I have to bear it in mind).
I tried the Nz function, but It's either not what I need or I'm doing it wrong.
How do I get this to work?
Many, many thanks!
Hi All,
I am new to access and this forum, so hello all.
I am trying to build a database to keep records of my bird sightings. As you might have surmised; I am a birder.
I have come to a holt on creating a complex relationship between the Bird Entry From and the table that contains a list of British birds.
In Bird Entry From two of the fields are for entry of the bird name, one field being the Common Name and the other being the Latin Name. They are both drop down lists that contain all the birds from the table, this being done by import data. The table that holds the bird list has two fields One is called Common Name and the other is called Latin Name, this being the same as the filed names in question in the Bird Entry From
This is where I am coming unstuck. What I would like to happen is that when I enter a bird in the Common Name field (either by typing until the bird is auto entered from the drop down or using the drop down to find the bird) it automatically enters the Latin name in the Latin Name field and visa-versa, but I have become very frustrated with trying to do this.
Am I wasting my time? Or is it possible? And if so would anyone be kind enough to tell me how?
Many thanks,
Simon.

What is making this so difficult?
As you all know Im not a expert on databases but work in a volunteer basis in a small community area where we have no money for people to do anything for us.
Im proud because I did the other database and its up and working but this one has got me beat.
Im setting up one for the volunteers, which has computer knowledge, any basic training they need, when they are available and what tasks have been set for them.
I need to have a one form which has just their personal details but to be able to put in data on the other forms and it will link back to the volunteers name.
Ive attached what Ive done and Im sure your all going to laugh - but any help would be appreciated

Trying to set up a fairly simple DB. Here is the layout:
tblRoom(roomID, roomNumber, rackOne, rackTwo, rackThree)
tblStudent(studentID, name)
Each student will be assigned to one, and only one, rack. There will be 3 students to one room. One student can only have one room but a room can have many students... I store studentID in the rackOne, Two and Three fields. My problem is when I try and querry for the information so as to display actual names rather than ID's. I'm not sure If my querry is the problem or if I've set the tables up incorrectly. Any insight is much appreciated.

I want to be able to open up the volunteer table and have it show me the movies they have worked on. The movie data table will list who worked it, but the volunteer tables are not.
Any ideas?

I have to tbls which have indeterminate relationships and I'm told that ther is no unique index found why is this?
i am using emplyID on both tblCommission and tblSales both are number type.
I might not need the commission table as I'm using this is calculate commission as said im my previous post
at one point in my database I have two tables and for everyone record in one table I may have either 1 or 0 records in the other. How do I express this in access design? Since it's an optional 1 to 1 relationship I guess?
View 1 Replies View RelatedI was wondering if anyone could help me with a query. Basically I am doing (or trying to do) a small database to track childrens progress in my mums primary school. I'm doing this for free as the budget is rubbish for this type of thing and i dont have enough knowledge to ask for payment anyway! I want to get it right from the start and I think if I get the relationships right initially then I can complete the rest of it on my own. I did this at university (normalisation etc) but ive not used it since i left in 2002 and so have practically forgotten everything i ever did.
Basically, the child comes into the school and is predicted a level in maths, reading and writing. Then in the october, feb and july of each of the 2 years they are there, they are given actual assessment levels. They are also given a prediction level at the beginning of year 2.
So far I have one table with student no, surname, first name, gender, ethnicity, year group and SEN(special educational needs) - with the primary key being student no.
This is where I get stuck - do I go for a maths, reading and writing tables and split it that way - or on an assessment basis, so prediction yr1, october yr1, feb yr 1 etc etc. Or is this completely wrong? Am sooooo confused, so any help would be greatly appreciated.
The outcome I want is to be able to query a childs progress, so for example: show children who achieved a 1a in yr1 maths, and then out of those children, who achieved a 2a in y2 maths (as this is the required shift in progress set by government). I really hope that makes sense.
Thanks in advance

I'm rebuilding my database from scratch now that I've learned a bit from the forums about developing a proper database and I want to investigate whether I have the relationships set up correctly, as I seem to be using lot of one-to-one relationship, which most articles say is very rare, and whether I am formulating many to many relationship correctly. Here is a screenshot of my relationship.
If I've understood this correctly, one-on-one is desired if you have a subset of data that is applicable to the main table only occasionally and is dependent on the main table's data. Have I used that correctly?
As for many to many relationship, articles say this is formed by having two one to many relationship linked together in a table. In my screenshot, you can see that tblAdvocacyVisit is the linking table. However, I've set GuestID as a one-one relationship whereas ClientID is one to many relationship, reasoning that since I do need to relate the Guestl Logbook data to Advocacy table for some queries I will be performing later, this will save me some work. I'm afraid that this may compromise RI or something like that. I can simply add a PK autonumber to tblAdvocacy to revert the GuestID as a one-many relationship, but can't see how that would not create more work in queries or so...
Oh, are the lookup tables supposed to be related at all?
TIA.
Edit- Updated the relationship screenshot.
