Tables :: Limiting Table Input Based On Variable Values
Feb 7, 2014
I'm quite new to Access and am just working on a little practice database where I keep track of sales of a product.
Basically I have a table keeping track of the different types of products, a table keeping track of customers, a table for orders and one for replenishments of stock. I have a query that calculates the stock of each type of product based on replenishments and sales.
Now I want to make sure that a customer can't order any more than there is in stock. I know you can restrict what's entered into a table with a validation rule but that's only for static restrictions. After searching the internet for an answer I've pretty much learned that I can't really make this restriction directly in the table, correct? But then how can I achieve this? Do I have to restrict the amount through a form somehow?

I'm using Access 2010. I need to calculate a score based on values selected in a table by looking up corresponding values in other tables. I have a "Project" form to create new entries into the Project table (see Table 1). When I create a new project record, I will select values for the Payback and Need fields by selecting options from a list. The Payback list is pointed at Table 2 and the Need list is pointed at Table 3. In the below example, I created the "ABC" project and selected "1 year" for the Payback field and "Repair" for the Need field. Pretty simple.
Now that I have the "ABC" project loaded to my Project table, I'd like to create a report that will show a "score" for this project. The score should be calculated as follows: Payback Impact + Need Impact. In this example, the score should be 30 (Payback Impact of 20 + Need Impact of 10).

I have a very basic three table structure.
Clients
ClientID (PK)
ClientName
Boats
BoatReg (pk)
ClientID (FK)
Description
Quotes
QuoteID (Pk)
ClientID (fk)
BoatReg (fk)
What I would like to do is for the BoatReg field in the Quotes Table to only display the boats that have been registered to the Client that has been selected, currently it displays all the BoatRegs.

This is the first time that I have done any major work with forms. After I thought I had finished a problem came up. There are several forms that are use to input information into a table. When the form is opened it grabs an automated number for tracking. The problem is, that if the form is opened and then closed it creates a line of data with all null values.
What I would like to do is have the form open, the user fills out the information, and upon pressing the "save" button, the data will save to the table. I think I need to have each text box write to a variable and then save on the click event. Or I could be completely wrong and need to do something else.
i'm guessing this is something I would learn in Forms 101 if i had ever taken that type of course
Thanks

I'm trying to make a report that a untrained user can use to review the relevant data from the database I'm creating. All of the work I've done so far has been directly in the tables . Here's a quick outline of my general data organization:
Department:
DepartmentID(PK)
DepartmentName
Employee:
EmployeeID(PK)
EmployeeName
DepartmentID(FK)
Needs_Work (check box)
[code]....
Basically, I want the user to select a department to view using a combo box or option group (which I'm not sure of how to do in a report). Then, I want to view the employees within that department sorted first by whether or not the Needs_Work check box is selected, and then by how many of their competencies are unchecked.

How to limit input data on the same month for each patient? The field is a data/text box on a subform
I found this code on Form Current Event!:
Code:
Private Sub Form_Current() Dim intMaxNumRecs as Integer
intMaxNumRecs = 5 'Max Number of Records to Allow
If Me.NewRecord Then With Me.RecordsetClone
If .RecordCount > 0 Then .MoveLast: .MoveFirst
If .RecordCount >= intMaxNumRecs Then
MsgBox "Can't add more than " & intMaxNumRecs & " records in the demo database!" .MoveLast Me.Bookmark = .Bookmark
End If End If End With End If End Sub
But I want a monthly limit...

I have two tables linked by ID (Table1,Table2)
The Table1 holds data that is a request for a task.
ID, Request, Task_tms (the number of times the task is required to be done)
1, Make a cup of coffee,15
Table2 is my allocation of people to the tasks.
ID, Person, Task_done (the number of times this person has done the task)
1,Sally,10
1,Eddie,5
What I want to do is to limit the amounts of allocation in some way (ie in this case if I have already put 10 for Sally then I would be unable to put anymore than 5 when entering the amount for Eddie.
Additionally if I were to allocate all 15 to Sally then no additional people would be able to be allocated to this task (ID 1)
The two table are in datasheet format linked on a form.

Need some ideas on how to detect if Time Now is beteen preset values.
It is in connection with a Machine Monitor system being I am probably going to be asked to develop.
Problem is night shift. They work normally 20:45 to 06:45 following morning
I will be accumulating elapsed minutes of shift and working minutes by running an On Timer event updating both values by 1 each minute providing certain criteria are met.
One of the criteria will be that machine is supposed to be working.
So I was planning to set a flag indicating Working Yes or No based on the Time Now being between start and end times.
This is fine for normal day working and normal day shifts but is a problem with Night Shift.
Ideas on how to handle welcome

Hi,
I have a query which uses manual input on two fields. I would like to automate this query by pulling the input values from another table.
How do I read the input values from the other table instead of having the users type them in ?

I'm using Access 2010 and am trying to pass a variable in a form field and store it in a table i.e. I have a customer database with various fields: Customer_ID, Customer_Name, Customer_Address etc. After selecting a particular record i.e. Customer_ID = 20 l need to store the record number '20' in a temporary table. I presume that l could then use Dlookup to read the info back at a later stage.

The database I am building is for Student & Alumni administration at a non-profit culinary school. In the various forms for entering student information and for defining tests and recording test scores, I would like to not have to re-select things like Class Number or Test number.
I was able to use the Test Number field as Link Master, Child in a Test Results sub-form where Test Parameters is the Master form. But I am not able to link with the Class Number, getting the error message: "The setting you entered isn't valid for this property" even though it is one of the Suggested Link Fields. The form record source is a query linking the Class Table, Test Parameters, Test Results and Students.
I noticed that I can eliminate both Class Number and Test Number from the sub-form. In the underlying query, both these fields are updated. However, the underlying Test Results table does have the Test Number but not the Class Number. While there is still a "queryable" link from the student to the Class Number, I would very much want the Class Number to be stored in the Test Results table.
Is there a way to accomplish this through the sub-form Link Master/Child property or any other/better way to inherit both the Class Number and Test Number in each Test Results record entered?

I have a TABLE with the following data:
- EMPID
- LASTNAME
I have a form with the folliwing data:
- text box for user to enter EMPID, txtEMPID
- LASTNAME
I would like to create a button to initiate a query to do the following:
- once the user enters a EMPID in the form, it will search in the TABLE under the EMPID field...
- if the user enters an EMPID that is in the TABLE...display "Y"
- if the user enters an EMPID that is NOT in the table...display "N"
- a error message box needs to pop up if "Y" to alert the user that "the EMPID already exists and that duplicate entries are not allowed"
One of my main questions is how do I run a query based on the users input and search a table? would the following work in the query?

I am new to VBA and I'm trying to write a query that will update a table with dates based on user input. For example a user will run data each Monday and that date will be day01. The date table has 28 days total and I need each day row to update with the next date i.e. day01 is 12/30, day02 is 12/31, day03 is 1/01 etc..I am having issues just running the update the query. I get a too few parameters error message on the strsql statement. There are only two columns in the table, order_day(date column) and date_value(text). I want to update order_day. I also need creating a loop so it knows to go back and add days to the other values.
Here is what I have:
Code:
Sub Update_Dates()
Dim rs As Recordset
Dim db As Database
Dim lmsg As String
Dim transactiondate As Date
Dim strsql As String
[Code] ....

I have an inventory database with a few tables:
1 with product info
1 with customer info
1 with incoming stock
1 with outgoing stock (orders)
I also have 3 query's:
Total incoming stock per product
Total outgoing stock per product
Total current stock per product (based on the 2 above queries)
I'm trying to make a form through which orders can be placed, and I want to limit the amount that can be ordered based on how much stock there is.
I've been told I can use the 'before update' event on the form to achieve this, but where to start. Do I use a Macro, an Expression, or do I need code?
Also, currently the record source for this form is the outgoing stock table, but I guess I'll need to add my 'current stock' query to the sources before this can work? And maybe even my other 2 queries because my 'stock' query is based on the other 2? But I can't really seem to get that to work either.

Hi, not sure if this is possible or the most economical approach but here goes:
I have a lookup table (tblHolidays) with a list of holiday dates (fieldname "HolidayDate") in it.
I need an update query that can check all "StartDate" values on a table called "tblMasterLog" and where this date matches the ones on "tblHolidays", will add 1 day to the "StartDate" and then keep repeating until there are no more dates to change.
Can this be done?!
Thanks in advance

I'm attempting to build a simple database for a martial arts tournament registration. The weight division (Fin, Fly, Heavy, etc.) depends on the age, the sex and the weight. I've tried this several different ways, most recently by using one table called "competitors" with all the entrant's information, and several other tables based on the age class/sex (i.e. I have a table called Age 8-9 Male with the weights and divisions in it, and other tables for the other ages/sex).
So, basically, what I'd like to have happen is a report that will lookup in the correct table the division, based on the weight entered. In other words, for a record where the age is 8-9 and the sex is Male, the report compares the weight to the values in the 8-9 Male table, or if the record is a 12-13 Female, it looks in the 12-13 Female table for the weight, and places the correct division in the Division field of the report.
Probably going about this wrong.....but any help would be appreciated.

I need to be able to query the service dates for the bill. So I can query 1509 for the .billYYMM and .readdate and it will give me the TO Date. How do I in the same query tell the query to subtract 1 from the BillYYMM that I just entered and give me the read date for that field in that query? So Query 1 MBRHISTDETL.BILLMOYR and in the criteria box use [Enter the Bill Month Year YYMM you want to search for] will allow me to run the query at any time for any bill month year that I enter. So another field in that query is MBRHISTDETL.READDATE. So to get the FROM date and the TO date i need the following MRBHISTDETL.BILLMOYR (whatever I enter as input) and MBRHISTDETL.READDATE that corresponds and then I need [MRBHISTDETL.BILLMOYR]-1 and MBRHISTDETL.READDATE. The first gives me the TO date and the 2nd gives me the FROM date?

I have a function that capture a report activity ,open, close, updated by query, etc.... I have a report that has a inputbox on the open event that tell the user this date the report will display is from a previous update and ask if they want to run the query to update the data.
What I was hoping to do, is have this inputbox only fire if the date and time written when the last update occurs was 24 hours ago.
Can I capture the date and time that the function captures and writes to a table as a variable and you that date and time to detemine whether that inputbox fires?

The attached Access XP file demonstrates my problem. I've included a form to make testing easier.
Each record in the Projects table has one or more linked entries in the Keywordlink table, showing keywords that apply to that record. Each record in Projects has a Yes/No 'Utility' field.
A third table, Keywords, supplies the keywords that the user can apply to records in Projects, using the subform on the main form. The Keywords table also includes a True/False 'Utility' field. I have set this to True for for the first three keywords.
I need a query, a series of queries or some VB code that updates Projects_Utility for all records to True if and only if the record's linked entries in Keywordlink include all of the keywords for which Keywords_Utility is True (a boolean 'and', as opposed to an 'or'). Otherwise, Projects_Utility must be set to False.
In the attached file, with the current settings in the Keyword table, the 'GetSelectedProjects' query should then produce single-row listings for ClientA and ClientF.
I'd appreciate any help you can give me on this. I'm not a programmer, but I can manage a bit of VB code if I have to.

I have a table (tblConversions) that I'm using as a base for replacing values in a different table. tblConversions is set up as such and is made up of nearly 100 records:
ID LABEL CODE
1 Ashaway ASH
2 Barrington BAR
3 Bristol BRI
4 Jesse Smith BUR
....
Another table (tblSysItemLoc) has nearly 1,000 records with a field for Location Names such as Ashaway New Books, Ashaway Fiction, Ashaway Non-Fiction, Barrington DVDs, Barrington Reference, etc. Other fields in this table are just statistics.
What I need to do is loop through tblConversions, and find in tblSysItemLoc where the Location field Starts With the value from tblConversion.LABEL and replace the Entire field with the CODE. For example, from tblSysItemLoc "Ashaway New Books" gets changed to "ASH", "Barrington Reference" gets changed to "BAR", etc.
I feel like I need a loop inside of a loop, but I'm not sure where to begin. Loops are not my specialty.

I'm developing a database for the hospital I work in. One purpose of this is to keep track of patients with temporary invasive devices (there are many types such as urinary catheters, ventilators, etc.), specifically how many days each patient has a device for. Each device is associated with one patient only, but one patient may have many devices. Here's how the associated tables are set up:
1. tblPatients - PatientID (PK), LastName, FirstName, DOB,...
2. tblLocations - LocationID (PK), LocationLabel,....
3. tblDevices - DeviceID (PK), DeviceType, Device, DeviceDesc
4. tblDeviceUse - DeviceUseID (PK), DeviceID (FK), PatientID (FK), LocationID (FK) (where in the hospital was device inserted, e.g., operating room, bedside, etc.), DeviceStartDate, DeviceEndDate
5. tblDeviceDailyLog - DeviceLogID (PK), DeviceUseID (FK), DeviceDate, PatientLocID (FK) (area in the hospital that patient is in)
All primary keys except for PatientID & LocationID are Autonumbers; and the tables are linked appropriately.
Whenever an entry is made into tblDeviceUse, I want there to be new records to be automatically generated in tblDeviceDailyLog for each date between the Start and End Dates. For example, patient A123 had a urinary catheter from 1/1/2000 to 1/10/2000 that was inserted while the patient was in the ICU, but the patient was moved to the Medical Ward on 1/7/2000. So tblDeviceDailyLog should have 10 new records associated with this device, one for each calendar day, with the appropriate location for each day.
