i was wondering how to go about doing this, i currently have a query which returns all the payments due in the next month, going to a report which acts as an invoice. I was wondering how to create a unique id for each invoice and store the last id so that i can automatically itterate it later
View RepliesI am very new to db programing so please forgive for such a simple program.
Here is the deal. I have a db for about 500 students.
I would like the table [Students] to create a unique ID "number" for each student. I would like the number to be based on information from the same table. For example if the student's name is John Doe and his number is 555-1212 then I would like to the id to be JD1212. I plan on using more than name and phone number but this was just to show you, what i am trying to get done.
I can do this using a form and a calculated control, but I can't get the table and form to kiss and make up. I was also told you can't save data from a calculated control in a form to a table and it is gernerally not a good idea, so I was told.
Any help would be appreciated.
Sincerely,
Pastor Nick.
Hi all,
Got my job database going quite well, at the moment, it generates a job number form the first 4 letters of the customers name, and the ID (autonumber), so for example mr smith's job number would be SMIT0012 (assuming the 12th entry in the database)
Now this works fine, tables are linked and the database access the tables via a mapped network drive for other pc's (2) to use. But the problem is, if the database user were to be at a remote location with a laptop, how could this work? I could use a local copy of the tables but then of course the ID's wouldnt match! Can anyone offer any ideas on this?
Thanks
I'm working on a database that has to be done in Access and in coming up with a unique ID for each worker I want to take the first letter of the first and last name and the last 4 digits of their social to create the UID for the table. So for FIRST_NAME:Homer LAST_NAME:Simpson with SOCIAL:123-45-6789 his UID would be HS6789. Is there a function within Access that would allow me to do that, or is that something that's just too advanced?
View 9 Replies View RelatedHi all,
I have been trying to incorporate an access DB in to our business for sometime, but keep coming up against the same issue. We have a numbering system for the jobs we do, which was invented many years ago and cannot be changed. It is in the format "month/Year/unique 3 digits" the 3 digits are sequential, i.e. 02/07/123 ... 02/07/124... etc. I will need this all in one field.
So far I have managed to get the month and year (easy enough) with the expression "=Month(Now()) & "/" & Right(Year(Now()),2) & "/"" Now I need to get the sequential 3 digits at the end, however, I am not sure of any way to do this and it has stumped many people. I have a field that is autonumbered, but don't seem to be able to add this to the end of the expression.
If any of you have any suggestions I would be greatful - bear in mind I am only a begginer at this.
Thanks in advance.
What I have is a small POS system I'm trying to create a unique invoice number for each transaction (multiple records)
I have two tables, one named "CurrentTransactions" and one named "Past Transactions".
I have everything working except the invoice number my system works by adding pre defined records into the table "CurrentTransactions" and once the sale has been finalised it transfers the data to the "PastTransactions" table.
take the last number from the "PastTransactions"."InvoiceNumber" to create an invoice number in the "CurrentTransactions", and I want to be able to do it using an expression in the default value property as opposed to in the form ( I've tried the form way but using Dmax would require me to almost rebuild my entire POS system )
Hi,
Anyone know how to create a combo box that has unique month and year entries from a table (month in one column and year in another - i.e. 2 columns)?
I've been able to get the textbox of the combobox to output the correct format using a custom format but it does not affect the combobox data. Also, I'm not sure how to separate this by two columns...
Any help would be much appreciated!
I have a rental database and I print several contacts for leases etc. what I want to do is have a unique reference number or something inserted to the report every time that it's printed. What I am trying to achieve is to keep track of which tenant corresponds to the report (Lease) printed by using reference number.
There is a seperate form which holds the tenants details and I would like to have a field on that form which would show the same reference number as the report so I can track which report was printed for who.
Whats the best/easiest way to accomplish this?
I'm creating a database using existing data from an excel file full of contact details. What I need to add is a queue type system where each contact in the database has a "Place in Queue" number which is unique obviously.
Lets say Alan is number 1, Bob is 2 and Chris is 3. They have these corresponding numbers in the queue field for their entries.
Now what I need to have, through use of a form, is a way of changing Chris from number 3 in the queue to number 1 and thus have Alan automatically shift down to number 2 and Bob to 3.
I've been on other forums with this problem but no one can solve my problem.
I've created a database with 3 tables that are linked:
- tbl_customer
- tbl_rates
- tbl_destination
They have the following fields:
tbl_customer
- cust_id
- customer_code
- first_name
- last_name
- company
tbl_rates
- rates_id
- cust_id
- rates_id
- currency
- pre_rate
- cur_rate
- fut_rate
- comment
- eff_from
tbl_destination
- dest_id
- destination
- destination_code
What I've done is created a form based on the tbl_customer table and used tbl_rates as a sub form. tbl_destination is used to populate a combo box that is situated in the sub form.
Each customer has their own rate sheet. Each rate sheet has different destinations and rates. Rates for the same destination are constantly changing. I need to use this spreadsheet to record the history of every change made to the rates of a particular destination. To do this I've just added the same destination with a new rate.
Now, what I want to do is to create a query that will only show the latest entry of a particular entry.
Eg. tbl_rate
Rate_id - Dest_id - currency - pre_rate - cur_rate - comment - eff_from
1 - 1 - £ - 0.01 - 0.03 - increase - 19 Sept 05
2 - 2 - £ - 0.12 - 0.14 - increase - 19 Sept 05
3 - 1 - £ - 0.03 - 0.02 - decrease - 23 Sept 05
I would want the query to show me the following from the above table:
Rate_id - Dest_id - currency - pre_rate - cur_rate - comment - eff_from
2 - 2 - £ - 0.12 - 0.14 - increase - 19 Sept 05
3 - 1 - £ - 0.03 - 0.02 - decrease - 23 Sept 05
Basically, the query should only show the latest entry which involves Dest_id '1' because there were two entries with the same id.
I've been given advice about this issue but none that actually work.
I would be grateful for any help on this matter.
I have a query of 11 employees and their pay for jobs done. Only problem is there are 15 completed jobs with some of the employees doing more than one. When I run my query its only displaying unique name results so I'm only getting 11 results of the 15 jobs instead of all 15.How would I change the query to that the results are only unique employee names?
View 1 Replies View RelatedI have a roster of people where each person may work on a specific task during a given period (a month, or a quarter, etc.) and each person is assigned to a team.
Team Jones has 30 people on it. There are 5 tasks that a person on that team may or may not work on during Q1 of 2013. Here are those tasks:
1. Business Analysis
2. Project Planning
3. Testing
4. Test Planning and Preparation
5. Quality Inspection
Now, what I want to do is to find the unique instances for each task where 1 or all of the 30 people worked on that task for the quarter. To further illustrate, say for Business Analysis that Mary Smith did Business Analysis in January, February, and March. She performed that task 3 times (1x in each month) but I am only concerned about knowing that she did perform Business Analysis during the quarter (so I'd like to show a 1 instead of 3).
Ideally, if everyone on Team Jones did Business Analysis during the quarter at least one time, I am only concerned about the one instance where they did and the first occurrence of it, not the other occurrences. So if everyone did do Business Analysis for the quarter, my total count should not exceed the count of members on the team (in this case, the 30 people). So the distribution could look like this (I'm just making this up but this is what I'd like to see):
Task
Team
Jan
Feb
Mar
Total
Business Analysis
Jones
7
15
8
30
My fields in the table are:
1. Task
2. User
3. Date
4. Team (there are 5 different teams)
Is this doable in a query?
I don't know if I'm going about this problem correctly. In a nutshell:
I have a table which contains a number of fields, only a two of which are important for this task, as indicated below.
| ID | Type |
Where ID is an alpha-numeric identifier (say a store number), and there are three potential types, plus Null values. For this, we'll assume the three types are Fruit, Vegetable, and Grain (plus Null).
An example dataset might look like:
0-4 Vegetable
1-2
0-1 Grain
1-2 Fruit
0-4 Vegetable
1-2 Vegetable
0-1
0-2 Fruit
0-4 Grain
1-2 Fruit
0-4
0-1 Vegetable
0-3 Fruit
If I want to know how many stores have Vegetable, I could put "Vegetable" as the criteria in the query and set UniqueValues to Yes. Then I would get three unique values, one for each Vegetable existing at a unique store.
But, what if I want to know at which stores Fruit exists and Vegetable DOES NOT. Is there a way within Access to find all the records with "Fruit" as the criteria and then eliminate those with ID numbers matching the dataset with "Vegetable" as the criteria?
In other words, if I do my "Vegetable" criteria I end up with the resulting dataset:
0-4 Vegetable
1-2 Vegetable
0-1 Vegetable
If I then use "Fruit" as my criteria, I get the following dataset:
1-2 Fruit
0-2 Fruit
0-3 Fruit
Since Store 1-2 has Vegetable, I want to eliminate it from the list so that my resultant list is:
0-2 Fruit
0-3 Fruit
Is that possible?
Sorry for the long bizarre example, but I thought it the easiest way to make the situation clear. I'd really appreciate any suggestions anyone has on dealing with this situation!!
Thanks
I'm having trouble getting a query to return a simple count of unique lot numbers for a given ProductID. The data is stored in a large table where each test result of a stability program is stored. Each result has an associated lot number, product id and several other data fields. I've managed to get a combination querries to return the count, but if the lot has both real time and accelerated data then the counts are added and reported as double for each type. The current SQL is as follows.
SELECT tblProducts.ProdName, Count(qryAccelerated.Lot) AS AccelCount, Count(qryRealTime.Lot) AS RTCount
FROM qryRealTime RIGHT JOIN (qryAccelerated RIGHT JOIN tblProducts ON qryAccelerated.ProductID=tblProducts.ProdID) ON qryRealTime.ProductID=tblProducts.ProdID
GROUP BY tblProducts.ProdName
ORDER BY Count(qryAccelerated.Lot) DESC , Count(qryRealTime.Lot) DESC;
qryAccelerated and qryRealTime are simple SELECT DISTINCT querries returning the product id and a list of unique lot numbers for that ID.
(e.g. SELECT DISTINCT tblResults.ProductID, tblResults.Lot FROM tblResults WHERE (((tblResults.TypeID)=3));)
Currently the top query returns 4 in the both the AccelCount and RTCount columns when there are only 2 unique lots for the product. Other products without both real time and accelerated lots count correctly.
Any help is greatly appreciated. Thanks.
Hi, I have a query with approximately 100 criteria. That is a bit much, thus I have made a table of the criteria and in the query a relation laid to this table. The criteria are countries with an increased risk on tbc. I point these query on a column with parent 1 and afterwards on the column with parent 2. Then I want the results from both query's in a table, but without double rows. I have tried this with a merge query but these only give the results where the hits for parent 1 and parent 2 are the same. This is by far not always the case, so, I miss all hits where there would be a hit for one parent only. Cumbersome tale, but perhaps there is someone who understands what I mean?

I got a large transaction file with deplicated records!! For unit price checking, I need to copy the last 10 unique records to another file with the same criteria but price is not the same as the current checking record.
For instance, I got 5000 records with around 400 records unit price is not the same as history. For each checking, I needed to copy the same criteria historical records to a tempory file and then delete corresponding duplicated records first, following by another deleting action only to keep the last 10 records according to date field.

I would like to do as a report. (Dates would always be from Sunday to Saturday). I am not sure it is possible to do that. I suppose first it would mean:I would have to do a query to separate the times from the dates?I would have to find a way for Access to find the unique dates and unique names?Does it mean I have to use cross tab queries?
Hi,
I've been given a flat-file database to 'improve'. One field is simply titled 'Room' and refers to a room number in a school. I want to create a MakeTable query that will run through all the records and make a table containing one instance of each room number (for normalizing). Hope that makes sense!
Any help much appreciated,

Hi Guys, I'm new here and fairly new to anything indepth with Access.
I'm using Access 2003 and have a table which has a number of customer records. The two relevant fields are the CustomerID which is a simple integer and OrderDate obviously this is a date field!
What I need (to link in with the other forms) is a query that will return one record for each CustomerID it should be the most recent OrderDate.
I've had a few attempts and done a couple of searches but can't seem to find exactly what I'm looking for. If someone could point me in the right direction I'm happy to play with sample code and read up on bits other people have done (I tend to learn better that way) rather than just being given some code!
Thanks for any help you could can provide.
I am using a software drawing program that intelligently link information from a drawing to a database and vice versa. I have many tables and queries that I have created over time that enable auto populating of tables, creation of tables and so on. All of which enable me with tabular documents for ordering purposes.
The problem I currently have is: - I want to create a table that looks at an existing table, analysis various fields for duplicate information and then adds one record to a new table. This is to enable me to create a spares list based on the entire list.
I have a full valve list with various items, some duplicates some not. I am required to produce a spares list that considers only one of each type.
I have a unique query which lists all the films that we are screening over the next 3 months. I have added a COUNT field so that I can see how many of each films we are screening.
The problem is that i get duplicates of some films - and this may be because we may hold several copies of some films. I have attached two images which might explain this better!
What I could do with is knowing how to make it so that i get a list of films booked and how many of each, regardless of which copy of the film is used.
The SQL is:
Code:
SELECT DISTINCTROW dbo_Films.[film name], Count(dbo_Films.[film name]) AS [CountOffilm name]
FROM ((dbo_Films INNER JOIN dbo_filmCopies ON dbo_Films.ID = dbo_filmCopies.tblFilms_ID) INNER JOIN dbo_EventsFlicks ON dbo_filmCopies.ID = dbo_EventsFlicks.filmCopyID) INNER JOIN dbo_Venues ON dbo_EventsFlicks.venueID = dbo_Venues.ID
WHERE (((dbo_EventsFlicks.datefield)>=#8/1/2015# And (dbo_EventsFlicks.datefield)<#1/1/2016#))
GROUP BY dbo_Films.[film name], dbo_Venues.southhub, dbo_Venues.northhub, dbo_Films.Specilaised
ORDER BY dbo_Films.[film name];
I'm attempting to create an append query that will add new records only if there isn't an equivalent record already existing. Typically I would add the existing table to the query, and only add new records if the same do not exist. In this case, the table is maintaining records over time (start date and end date).
I have 4 tables:
[t_employees]
employee_ID
employee_name
[t_cities]
city_ID
citiy_name
[t_city_assignment]
city_assignment_ID
start_date
end_date
employee_ID
city_ID
[t_temp_employees]
effective_date
employee_ID
city_ID
I'm checking if [t_temp_employees].[effective_date] <> [t_city_assignment].[start_date]. However, if the employee has historical entries it will still add a record (in fact, it'll add multiple records).
How can I append a new record only if one for the same time period does not exist?
I have a set of devices that are assigned to a truck, on occastion they are moved from truck to truck, I need to be able to track where they are AND where they have been. Here is what I have:
ID (autonumber)
GPS ID (number, this is the specific ID to each device)
Truck Number (this is the specific ID for each truck
Installation Date (Date installed / moved)
I have created a query to show the data I need, I have put them in order based on date.
- I must keep each event stored on the table
Goal:
To show a list of the current location of each device, nothing more.
I have a basic query off a currency table :
Quote:
SELECT tblCurrencies.CcyID, tblCurrencies.Ccy
FROM tblCurrencies
ORDER BY tblCurrencies.Ccy;
Now - I have a separate table of balances, which is linked to the currency table by the same CcyID, and which also has identifiers to link it to other tables (e.g. AccountID)
As part of the above query, I want to return the count of unique AccountID's in the balance table for each currency. So in other words, I want to know, for each currency, how many unique accounts exist?
Each AccountID could appear one or more times in the balance table (one-to-many relationship), so I only want to count the number of unique ID's.
So I started with the following :
Quote:
SELECT tblCurrencies.CcyID, tblCurrencies.Ccy, Count(tblBalances.AccountID) AS NoOfAccounts
FROM tblCurrencies INNER JOIN tblBalances ON tblCurrencies.CcyID = tblBalances.CcyID
GROUP BY tblCurrencies.CcyID, tblCurrencies.Ccy
ORDER BY tblCurrencies.Ccy;
But this just gives the number of AccountID's per currency (regardless of duplication within them)
I found this article which informs me that a Count(Distinct) query won't work in Access and to use subqueries instead.
I have the following code:
Code:
Dim rs As DAO.Recordset
Dim db As Database
Dim strSQL As String
Set db = CurrentDb
strSQL = "SELECT DISTINCT tbl_contract_lev.ContractID FROM (tbl_leverancier_gegevens INNER JOIN
[Code] ....
The result of the query is a list fo unique values but by including the "count" function in SQL seems not te be working in combination with "DISTINCT"...
