How to find the max value of a field in a query... How does a query display the max record based on the primary key... want to isolate the last record created, the one with the max primary key.
View RepliesI have a combo named cbogroup. I have a tblGroup with several records (active, non-active, nursery, etc.). One of the records is *ALL*. Using the CboGroup the user can pick any of the records. Howeverr, if they pick the *ALL* record, I want the query to pull up animalID based on all records in the TblGroup. If another record is picked (i.e. nursery), then the query will pull up only animalIDs that are in the 'Nursery'.Can I put a (iff then) in a query in order to differentiate a query based on all group records or a query based on only one record?
View 14 Replies View RelatedI got this function which is supposed to find a record based on the primary key, and then give three fields a value if they should be empty.
Public Function DoesXrefExist(faPersonID As Long, faRoleCode As String, faDorpID As Long, faDorpCode As String)
If (DLookup("PersonID", "PEOPLE", "PersonID =" & faPersonID) > 0) Then
End Function
Thats as far as i have got...for the next part.I get the feeling that i need to use the recordset object that exists somewhere.How do i access that recordset object? I have not been using any DAO or ADO, just straight VBA. I know i can create recordsets and stuff using DAO/ADO, but there must be a recordset that has been created already by the Dlookup command...
I have an existing database with multiple tables. Two tables have the same primary key Cab#.
1. When user clicks on the form on the menu form, I want to request the Cab# value from the user.
2. Then I want to get the record from the first table CabData based on the entered Cab#.
3. Then I want to create a new record for the second table Rides with five fields from CabData table inserted into the Rides record.
4. Then I want to display the new Rides record to the user for updating.
5. Then I want to save the new record to the RIDES table.
What is the ACCESS termonolgy to do each step? Are there any special details I should watch for?
I want my primary key to be
First 3 letters of surname + first 3 letters of forename + DD + YY (Date of birth)
I can use the after update event to update the primary key field but it won't get saved for some reason so have I missed something?
My problem is that I am trying to update a field (called 'Sold' which is a yes/no checkbox column) for a specific record whenever an event is triggered. I have two forms (derived from two tables), one is called frmInventory and the other is called frmSales. In frmSales, I made a combo box called 'cboItemID' that allows the user to select from a list of items from my inventory table. Each selection from the list has 4 properties, the first of which is the 'Item ID' from the inventory table. Lastly, I have a field in both frmSales and frmInventory called 'Sold' as mentioned above. What I want to do is that whenever I check/uncheck the box in the 'Sold' field in frmSales, I want the 'Sold' field in frmInventory to check/uncheck as well, but only in the record with an 'Item ID' that matches the 'Item ID' from the combo box selection. In other words, I want to match the 'Sold' field in frmInventory with the 'Sold' field in frmSales, but for only the record that has the same 'Item ID' primary key as the one I picked from my selection in the combo box from frmSales.
how to reference another table and check whether or not it's 'Item ID' primary key is identical to the one I specified from the combo box, and then take action to update the 'Sold' field if the IDs match.
I have a table, and there are many records, each with a unique value in the OrderNumber field
I have a text box on a form, and i want it to work so that the user types in a OrderNumber value, and it loads that record into the form (the form is bound to the table)
I already know how to load a record by record number, but how can i do it by OrderNumber value?
thanks

Hi All,
I have one table where ID field is autogenerated, and another field orderno which is not primary key. Now it has 2 duplicate values in it so when I try to make field Orderno as primary key, it is not allowing me to do so.
Can any one help me how to find the duplicate values using query.
Thanks in advance,
Jigs
I am looking to get a query to show my list of customers "Grouped By" [CustomerName], that show only the single [CurrentBalance] field for each customer based on the "Last or Highest" [RecordID].
Also, each customer can have up to 4 different [StockType]'s but at least 1 [StockType].So my results would look like this:
[CustomerName] - [StockType] - [CurrentBalance]
Customer#1 StockType#1 5
Customer#1 StockType#2 4
Customer#2 StockType#1 5
Customer#3 StockType#1 5
I have 2 tables. One has employee info and the second has time data based on thresholds reached in the employee info. Obviously, a basic join will bring in all of the threshold records. How do I get it to only pull in the one that satisfies the threshold condition?
View 5 Replies View RelatedHello all, I have a couple questions. First I am trying to create a select query that will show the results that I have two fields , one is "Date" & the other is "Current" For the date I am using the a between statement "Between [start] and [end]. Under the "Current" I have "Applied" & below that I have "Overage" The problem is when I enter my date range, it shows all records with the Overage or Applied, but if I go & remove either "Overage" or Applied, then it works fine.
Is there somthing that I am missing
Second question is when using a find command box, is there a way to have it search multiple tables, if so how would I set the find box to search both tables, if the table names were called Let say Table 1 & table 2
Thanks!!!
I need to find the latest number using a query.
All of the numbers follow this format:
[Doc No]
ABCD123
but the tricky part is the number could be suffixed with a revision. It is the latest revision I would like to find. For example, If I have a number followed by 3 revisions I would have:
[Doc No]
ABCD123
ABCD123+200
ABCD123+300
ABCD123+400
I need a query to give me the latest revision, in this case
[Doc No]
ABCD123+400
There is a possibility there are no revisions in which case the latest will be
[Doc No]
ABCD123.
How is this possible in a query???
I have a database that is used (partially) to enter appointments during a day. In the appointment column I've entered the date and time as dd-mmm-yyy-hh-nn-ss. I'm now trying to search for appointments entered on a specific day through a user input ([Enter Date] in the query criteria) Problem is, this only returns records where the time hasn't been entered and the time shows as 00:00:00.
I've tried CDate which gives me add/mmm/yyy return. if I try to search against that I get nil returns though. As a test I put DATE() in the criteria but it then says that it's an invalid foremat. I've also tried various machinations of "Like" and "Between" without success.
I have a make table query that gets its info from another table that is updated weekly. I would like that when we run the Query Type (Make Table), we would like to add a primary key to a field that exists already starting at 1 every time the query is run.
View 3 Replies View RelatedI need to create a query that strings data horizontally that corresponds to the primary key.
Example of what I am looking for

Part_No,
Mfg_No,
Mfg_Name
Query Columns: Part_No, Mfg_Info (Mfg_No: Mfg_Name)
Also if the part_no (primary key) has multiple values I need the data to string horizontally like this:
Part_No, Mfg_Info (Mfg_No1: Mfg_Name1),

I am trying to set up a user friendly front end to my database. I would like to have a form which allows the user to enter information into text boxes and then press a button which finds the relevant record(s).
I would like to use it to pin point an employee's record based on at least one piece of information, but possibly combined with up to four more by entering into these boxes. For example personnel number, surname, first name etc.
Is this possible and how do I go about setting it up?
I am aware of the filter function and queries but I can't seem to get either to operate in the way I have envisaged. They don't appear to offer the most user friendly solution, at least not in the format I have tried.
Apologies, but I am still getting to grips with access to be honest.
I have a dataset of about 70 columns but would like to remove any two rows that sum to zero (based on two columns) if the column "Units" are the same for the same "Bar code" thus to say "for the same 'Units' (for any two lines), check to see if their respective 'Bar Codes’ are the same and if so remove if their amounts sums to zero".
I have the following code which seems to be working but for relatively large data ( about 5k), it does not select all the data that meets the criteria:
Code:
SELECT *
FROM datatable
WHERE ((([datatable].[Unit] & [datatable].[Bar Code] & Abs([datatable].[Amount]))
In (SELECT datatable.Unit&datatable.[Bar Code]&abs(datatable.Amount)
FROM datatable
GROUP BY datatable.Unit&datatable.[Bar Code]&abs(datatable.Amount)
HAVING count(*)>= 2 and sum(datatable.Amount)=0)))
ORDER BY [datatable].Unit & [datatable].[Bar Code] & Abs([datatable].Amount);
identifying the bug in this code that makes it not pull all the data meeting the criteria.
See sample data below:
# Unit bar Code Amount
1. AAB Mac1 2.75
2. AAB Mac1 -2.75
3. AAB Mac1 1.24
4. AAC Mac3 35.00
5. AAC Mac3 -20.00
6. AAC Mac3 20.00
7. AAD Mac3 16.11
8. AAC Mac2 11.00
9. AAC Mac2 -11.00
10 AAC Mac3 12.05
11 AAF Mac3 -12.05
12 AAD Mac3 -16.11
13 AAC Mac4 35.00
I want to select records # 1, 2, 5, 6,7,8,9 and 12 since they are same units having the same bar code and their sums total zero.
I'm wondering what would be the best way to update a list of records based on today's date. Right now I have it to open the form based on the LAST record and then navigate to the record they would like to update, I would only like to show what was entered that day.
View 1 Replies View RelatedI have a table similar to the following:
PatientID | LabID | LabDate | Result
001 | 55 | 01jan14 | 9.5

002 | 66 | 30mar14 | 10.0
Using a single-step Access query, I need to retrieve, for each PatientID, the most recent LabDate and Result *of a given LabID*. Thus, from the example dataset above, the desired output for LabID 55 is:
PatientID | LabID | LabDate | Result
001 | 55 | 01mar14 | 8.7
002 | 55 | 01mar14 | 14.5
I have searched this forum and others, but have not found an answer that I can directly tanslate to my situation. I have successfully written queries (with included subqueries) that retrieve the most recent of all the Labs, but have failed at obtaining a result dataset that contains only the records within a specified LabID.
For example, the query below fails because whenever the most recent of *all* the LabDates is not the same as the most recent of *the LabDates with a LabID=55*, the correct record is not included in the results. In the example dataset above, 0 records are returned.
SELECT a.PatientID, a.LabID, a.LabDate, a.Result
FROM Labs AS a
INNER JOIN (SELECT PatientID, MAX(LabDate) AS MaxLabDate FROM Labs GROUP BY PatientID) AS b
ON (a.PatientID = b.PatientID) AND (a.LabDate = b.MaxLabDate)
WHERE (((a.LabID)=55));
I currently have a form to manage inventory. On the left side of the form, I have a list box that shows all of the items in the database and finds the record on the form based on the selection.
I would like to have toggle boxes or something underneath the list box that when clicked will sort the box by vendor and item and another that when clicked will sort the list by part number and then select the record on the form based on the selection at that time.
I have no idea how to accomplish this...can anyone help?
I have a file of transaction history from the accounting system. All of the payroll cash payments are coded as ZG. Payroll accruals are coded as ZC. I need a sum of payroll accruals by department that have the same date or later than the last payroll cash payment. How do I write that query?
View 1 Replies View RelatedI wanted to know if it is possible to set a rolling year based on the first recorded date for an individual. In other words, my table is updated every time an employee receives a point. The record includes the employee's name (empName), the date (dateOfOccurrence), and the point (occurrencePoint).
I would like to create a query that would be based on a rolling year from the very first record of an employee based on the first dateOfOccurrence. The first date/record of this employee would be the start of the rolling year. I am writing this in SQL in Access 2013.
Hi
I apologise if this is really basic - I am learning as i go along. I have designed a database. Most of the info is stored in the clientinfotbl. On the main form, I would have provided an option for users to search for a record based on its ID number and then pull up various forms accordingly. I am using the "find and replace" option to do this. My first question is, is there a better way? This feels a bit clunky!
Second question is, once I have entered a new record in the "newclientfrm" and go back to the mainfrm and search for that record, it cannot be found (once I have closed db and gone back in, it can then find it). Is there a way round this?
Any help would be hugely appreciated :)
Hi guys, need a bit of help with my Database. I have a Table with has ever player to play for my football club (1700 records in total), now i have another table called games (which has a record for every season played for each player, and is linked to the first table using the relationships and a field called ID. Make sense so far?
Well i then use a query to combine and calculate totals of certain fields and then i can use the query to show every single statistic possible on ASP pages. But when viewing my query in Access only 1699 records show up. So my thinkin is that either two records are identical (which is impossible because every p;layer has an ID and they cant be duplicates) OR a player has ZERO games in all years (in other words the player has no records related to it in the second table called games).
My question is, instead of searching 1700 records manually to find which one is there any way i can find which player would have NO records from the related table joint to it?
