I have a field called uniqueID which I would like to update based on 2 other fields that are already populated in my recordset (from running previous queries). I heard it is not possible to do an Update Select like shown below.
select max(uniqueID) from myTable where a = "value of field a from first record in record set" and b = "value of field b from first record in record set"
If it is true that I cannot do an Update Select then I am trying to do something in VBA. How can I Loop each row in the record set and store the values from fields a and b. I would obviously then need to pass those values into the sql above and store the result in a variable. I would then do a straight update to put the value of uniqueID into myTable.

I'm building a customer form using a list box of summary customer info on the left side of the form (CustId and Names) and customer details on the right hand side. I want the details shown on the right to be those for the customer selected in the list box on the left. I'm having problems getting the details to update when a different record in the list box is selected or clicked.
I originally set the data source for the detail records to the base customer table but couldn't work out how to update them when the list box was clicked!
I then tried creating a query with the select clause conditional on the list box (CustId = Me.qryContactDetails) and set the data control source for the detail record to the query (=[qryContactDetails]![FirstName]). The query works as expected but the field in the form just shows '#Name?'.
I tried adding a field requery on the List31_Click() event using Me.[FieldName].ReQuery but that didn't seem to change anything

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?

In my database I have a table that keeps track of a package of items. The package is assigned a package type (counter display, end cap, half pallet, full pallet for example). The record of the association of the package and it's type is held in the main table.
Each of these package types is either a case or a pallet (counter display and end cap are cases and half and full pallets are pallets) This relationship is kept in another table (we will call it description table).
Now, based on the type of package and therefore it being a case or pallet a UPC and a GTIN number are assigned. The GTIN number is different if it is a case or is a pallet. I have a table that stores all of the UPC and GTIN numbers available in 3 columns, one for UPC, one for GTIN Case and one for GTIN Pallet (the UPC is a standard 12 digit and the GTINs are 14 digit -with the first 2 different to designate pallet or case. and all are based on the check digit formula necessary)
The user assigns the UPC and correct GTIN number by clicking a button which applies the next available UPC code to the package and determines if the description of the type (case or pallet) and inserts correct GTIN number into that field. I actually have all of this functioning correctly.
Now the problem. If a user changes the package type, and therefore changes the description, I need to add code to the update event of the combo box that gives the choices for package type that does the following:
Check to see if the original package type was a case or pallet (it's description) and if by changing the package type it is now changed to the other, update the record in the main table to the correct GTIN number based on the existing UPC Code.
OR as I write this, maybe the code could simply update the main table with the correct GTIN code based on the new description and the existing UPC code. This was I would not need to check for a change just do the update every time.

There is a form which the user fills in 8 fields and saves it. Once saved, a new record opens.
However, I want to modify the save button to save the previous record and display a new record with only a limited no of fields to display from previous record, say 4 fields display from previous record, and the user fills the remaining 4 and saves it. Thus, the save cmd should continue to display 4 fields from the previous record.Already tried below code for save button but it displays all data of previous record as it is, doesn't display blank space for combo.118 and text2
DoCmd.GoToRecord , , acNewRec
DoCmd.GoToRecord , , acPrevious
Combo118.Text = ""
text2.Text=""

I don't have any database experience whatsoever so please go easy.
I'm guessing this kind of this is extremely simple for all of you.
I'm constructing a database of network resources and devices and I'd like to automatically update the values in one field based on the values of a field in another table.
The first table is called "IP" and the fields are called "Address", "IP Type" and "Device".
The second table is called "Devices" and contains the fields "Name", "Description", "Asset Number" and "IP".
Here's an example of the tables: (ignore the "code" tag. i've only used it to align my columns properly)
DEVICES:
NameDescriptionAssetIP
XserveFile Server107203.30.144.75
ProliantXDHCP119203.30.144.15
IP:
AddressIP TypeDevice
203.30.144.75Static
203.30.144.15Static
What I want is for the Device field in the IP table to automatically update it's values based on the values found in the Devices table. In this case, the values that should appear in the Device field in the IP table are "Xserve" and "ProliantX".
I've searched through but haven't found a complete solution, just little pieces which I'm too inexperienced to put together myself.
thank you

I need a way to dynamically store a particular value in "field_2" of the CURRENT record depending on whether or not the value of "field_1" of the CURRENT record is identical to the value of "field_1" of the PREVIOUS record within the same table. The table is sorted on "field_1".
So, if the value of "field_1" in the CURRENT record is "ABC" and the value of "field_1" in the PREVIOUS record is also "ABC", then store a value of "PPP" in "field_2" of the current record. IF on the other hand, the value of "field_1" in the CURRENT record is "ABC" and the value of "field_1" in the PREVIOUS record is "XYZ", then store a value of "WWW" in "field_2" of the current record.
I have a report that will use these results to count only the number of records that have a "WWW" in "field_2".
Is this doable, maybe in a query somehow?
I should add that whatever the solution, it needs to be compatible with Access 2000.

I promise I have searched, but I hav spent 10 minutes reading through posts that are unrelated...
What is the code to have multiple fields updaterd based on what is input into a field?
---
Example:
A ZIP Code Field, which updates City & State on the form when entered. (I have a table that has over 39,000 ZIPs w/ City & State already there)
---
I have several applications for this, but if someone could explain this use to me, I will be able to figure it out.
Thanks a million!!!

I have two tables, one table (1) hold three fields, one of those fields is the master key (index). The other table (2) has a field which I want to lookup from table 1, that part is working. In the combo box I get all three fields displayed as I make my selection. I want to copy the other two fields as text at the time the lookup index is selected. I do not what the fields to automatically update each time the table is displayed. I have looked at update macros, I've looked at VBA.

I have a query that creates counts of fields based on the data in other fields, basically it tells me that in a table there are two entries with value ABC????? and three of DEF????? , the query works perfectly.
When I create a form to display this data and base the form on the Query I keep getting a message box asking for the ID (key field) from the base table.
If I type * in the box (to denote all values) and press enter I get the results expected.

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 2 tables, one is like a main table, containing all of the main data, such as a Job Number, Customer, Quantity, etc. I have a second, related, table that acts a breakdown of information. There may be several related records to one main record, it entirely depends on the nature of the job.
What I'd like to do is run a function that looks at a main record, checks if all the related records COMPLETED field is ticked and then tick a field in the main record. I only want it to do this for records where all of the related records are COMPLETED.

I have a table similar to the following:
PatientID | LabID | LabDate | Result
001 | 55 | 01jan14 | 9.5
001 | 55 | 01feb14 | 10.0
001 | 55 | 01mar14 | 8.7
001 | 66 | 30jan14 | 11.2
001 | 66 | 30feb14 | 15.4
001 | 66 | 30mar14 | 13.0
002 | 55 | 01jan14 | 12.1
002 | 55 | 01feb14 | 9.9
002 | 55 | 01mar14 | 14.5
002 | 66 | 30jan14 | 16.5
002 | 66 | 30feb14 | 13.0
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));

My table occasionally gets a second record added for the same person. What is the easiest way to update the new record with the non-zero fields from the older record, then delete the older record? There is a unique id field as well as a timestamp, so knowing which is older isn't a problem. Is there an easy way to do this?

I have a form which is based on a select query that brings together 2 related (one to many)tables. When I keyin data to the form it does not update the corresponing table.
Is it possible for a table to be updated in such a way, or do I have to create a form based solely on the table(s) without using a query?

I am very new at Microsoft Access. I have two forms, A and B, that are filled out by two different users. Form A gets filled out first than form B gets filled out. Each has a name box as well as a birthdate box and a few other similar text fields. However, each form also has a few distinctive fields. I was wondering how I could input the common information in Form A to Form B so the user of Form B does not have to spend time retyping the name and birthdates again. In other words, I want to synchronize the similar records between the two forms. I would like the values to appear in a table as well. I would greatly appreciate it if someone could help me with the visual basic code. Thank You.

Can you update a text box on a form based on input of a date control? Here is what I have. I have several date controls on my form, and I want to update a status textbox based on which of these date boxes is filled out, but I need the status to be filled into the table as well. Do I update the field on the table, and then requery the text box? Is there some other method for accomplishing this?

In this table I have two fields Seats Available and Seats Remaining
When I register a student to a Course in the Courses table I would like the corresponding Seats Remaining field for that course to decrease automatically.
I can, of course, run a report or a query to see how many are enrolled in the course and then manually update the Seats Remaining field (which is what I currently do), but I would like this process to be automated each time I register a new student.

I want to create a parametric search for tools on the shop floor based on multiple fields [using VBA]
I've had a good search and turned up lots of useful things; but each example insofar has been fairly specific as opposed to a guide on how to implement it in a wider setting.
Let us say, for example, that my database has three fields each with a bound combo box: location; house-type; number of bedrooms
As I type in location, I want it to filter my results in the other boxes to that location (should be a simple case of applying a filter?) - which leaves me with all the house-types and bedroom-counts in that location.
As I type in the house-type, I want it to then narrow down the search again to filter the "location"+"house-type" to leave me with the available number of bedrooms.
What is the best way to implement this, given that I have about 20 fields*, some of which will inevitably be blank: as the user types in (or selects using combo boxes) the data required, it narrows down the search - and finally there's a "search all" button which returns all results matching the current criteria.
When I say "implement" I mean what underlying structure should I use. Is it best to create a query and update the query as items are entered, or would it be better to filter the form that's having the data entered?
The fields are organised sensibly into sub-forms for various characteristics (i.e manufacturing data, materials data, cutting data, etc, etc), don't worry - it's note a huge mess - and the code is all there to pull the data together as required!

I have created simple data base containing 2 tables connected each other and I wanted to make a form with fields taken from those tables and unfortunately it did not work and I got errors message.
Before I start to build the form do I need to create the query based on those tables and having the fields I need for the form? If yes, what sort of query, simplest one?

I search around online and did come across much info on code to how to hide fields. But, the problem is I cant seem to find a way to hide a certain amount of fields based on a number amount.
example: Lets say I have a 12 text fields to show 12 months of monthly payments, and lets say a client only has a 3 payment term. How can I list 3 under installment field and have remaining 9 fields auto hide since they wont be necessary? this way I only see what applies and not additional text fields.
