Minimum Record Set Must Be One
Mar 6, 2006
Hi All,
I have a main form and 5 tabs within that mainform that are subforms. They are linked by an EventID.
The subforms are continuous forms, but only one record is "required". What kind of code do I need to make sure that the data entry person enters at least one record in each subform.
Also, is there a way that when I am tabbing through my subform and get to the second record and leave it blank, that when I press tab it will take me to the first record of the next tab subform.
I appreciate your responses.

Does anyone have a good technique for enforcing a minimum number of records in a table?
I am attempting to ensure that in a table of Roles, there be a minimum of two Roles defined as Technicians. The field which identifies a Role as Technician is a Boolean.
I wrote a Function which does a domain lookup to count the number of Roles defined as Technician and am calling it from the BeforeUpdate event.
However, if there are 2 Technician Roles, and I mark a third Role as Technician, change my mind and try to unmark it...of course the Function can still see just the 2 existing.
I realize I can Undo the edit, but a user may not.
Thanks for any help.

I have a counter on my form which will increase or decrease depending on weather a number of tick boxes report true or false. Is it possible to set a minimum aloud value on a box regardless of other criteria. At present I can depending on certail criteria, finish up with a - number which for other reasons, I dont want.

I have a field in a report that is calculated to generate a dollar amount. Well the people who need this have some strange rules about how they get their dollar amounts. Mostly they just round up to the nearest dollar, which is no problem. But they also want a minimum charge of $2.00. So my problem is if the calculation works out to be 0.01 to 1.00, it will say 1.00 and it is going to be wrong because they will want it to be 2.00. So is there a way to set a minimum value for this field, or where should I go to try this?

Hi
I have a table (tbl1) with three fields/columns (Primary key, NameID, Number). E.g.:
NameID ... Number
Mike ........ 2
Mike ........ 3
Mike ........ 19
Ronald ...... 1
Ronald ...... 2
Greg ........ 7
...
I would like to make a query that lists each NameID only ONCE, with corresponding MINIMUN Number. So the result from the upper example would be:
NameID ... Number
Mike ......... 2
Ronald ....... 1
Greg ........ 7
How do I do it???
Thank you in advance

How do I create a query to return just one record, a minimum value for one of the fields, per group within a group that contains an ID field?
This is what my query is returning:
ID, UPC, MinOfAverage Unit Cost
19161, 026851003663, $1.15
15927, 026851003663, $1.11
4459, 026851003663, $1.18
19598, 029695215513, $39.73
15993, 029695215513, $39.29
11694, 029695215513, $48.81
This is what I need:
ID, UPC, MinOfAverage Unit Cost
15927, 026851003663, $1.11
15993, 029695215513, $39.29
I would be *extremely* grateful for an answer. I am new to this list, but I have plenty it MS Access help karma to my name, so I'm hoping to cash some of that that in.
Fingers crossed.

I have a query that is working, but I am looking to make it faster. We import 13 csv files daily into 13 Access tables. The files have an ItemID and price. We need to get the minimum of the raw data across the 13 tables & then manipulate the prices some (in the query) and get the lowest of the manipulated prices again for the 13 tables for each ItemID - some might be blank. We are using a MinOfList function in the query to get the minimum of the 13 numbers. But this is very time consuming since we have to run the Min function twice (with 13 input parameters) for each ItemID - about 15,000 records. It takes about 1 minute to run the query.

What I am doing is trying to have access identify and label various lanes of transit.
So, for example. I have the below...
Origin Destination Via Transit Time
Hong Kong New York East Coast 38
Hong Kong New York West Coast 32
China New York East Coast 34
China New York West Coast 29
Is there a way in Access to have it identify that Hong Kong to NY via West Coast is the "DEFAULT" where HKG to NY via East Coast would be "ALTERNATE" ?? And then do the same for the next origin? The table I have now has over 71 different origins but I need it look at each origin independently.

Hi all,
I´ve had this problem for a while but it only just recently became very annoying.
I have a chart on a form displaying data over time. I´m using two comboboxes to select start date and end date. There are A LOT of data in the underlying query. However the problem does not seem to be related to that.
When I select the starting date to be before a certain date, the chart suddenly sets its own minimum to 0 so that the line in the chart becomes almost flat (since the data reaches from maybe 20 to mayb 25).
This has to be a common problem, but is there a good solution?
I´ve checked the data so there´s no problem there.
Thanks in advance!
Fuga.

I'm trying to get my query to display only the minimum value within my query results. I have the following fields, CustomerID, OrderID, ProductID, WarehouseID, Freight Cost.
My current query will return results that show me the locations and freight cost of each product to my customers. My intention is for the query to only return records that has the lowest freight cost as there may be several warehouses with identical products but with varying freight costs due to location to customer.
I've tried to apply the MIN function on Freight Cost but it will only sort the records in ascending order instead of only displaying the record with lowest frieght cost.
Thanks in advance for your help.

The database I'm working on is used for personnel budget projections. Because some employees are hired mid-year, I need to be able to use various dates in my projection calculations.
I have 3 different tables - one with the employee start date, the other with the fiscal year start date, and the last with the start date of certain special pay tables. In order for my projections to work correctly, I'll need to return in a query the minimum of these 3 dates. I know how to do a minimum value in a single field within a table, but don't know how to select a minimum from multiple values in multiple tables. Is this possible.:rolleyes:

Hi.
I have one table with dates (1) and object properties. Another table has dates (2) and other info. What I need is a query that selects the dates (1) closest to date (2) and lists the respective properties.
I figured all I needed to do is a WHERE MIN (dates(2)-dates(1)) query. The problem is that Access (2000) rejects this query b/c aggregate functions are not allowed in WHERE statements.
Does anyone have an idea of how to work around this? The structure of the data is such that there will only be one minimum date > 0.
Looking forward to your ideas. THANKS !!

I have a normalised table containing the following fields:
<Unique ID> <Fund Name> <Date> <Return>
The data are time series denoting the monthly performance of investment funds. Funds can have any number of observations (e.g. March 1997 to June 2005). In addition, some funds can have performance gaps.
I would like to extract those funds that have a continuous performance history of 120 consecutive months between a specific start and end date. As an exmaple, the start date is July 1990 and end date June 2010:
- Fund A: performance history July 1995 to June 2005 (= 120 consecutive observations) INCLUDE
- Fund B: performance history July 1995 to June 2007 (> 120 consecutive observations) INCLUDE
- Fund C: performance history July 1995 to June 2000 (< 120 consecutive observations) EXCLUDE
- Fund D: performance history July 1995 to and June 2000 August 2000 to June 2007 (> 120 observations but gaps) EXCLUDE
- Fund E: performance history July 1985 to June 1995 (= 120 consecutive observations but only 60 after start date) EXCLUDE
how to build a query around this? Perhaps this needs implementation in VBA. Ideally, I would like to be able to select the start and end date dynamically and then run the query accordingly.

How to find the Minimum value of a column. This is my SQL:
SELECT *
FROM tblFinalMaster
WHERE (((tblFinalMaster.OperatingDay)=[forms]![frmEnterParameters]![Combo13]) AND ((tblFinalMaster.[Checkout Order])=([Forms]![frm01ATFTieLineCheckout]![Checkout Order])+2) AND ((tblFinalMaster.[From BA_REPORT])=[forms]![frmEnterParameters]![Combo5]) AND ((tblFinalMaster.[TO BA_REPORT])=[Forms]![frmEnterParameters]![Combo3]));
The part in blue, instead of pulling a +2, I want the Minimum value. Seems simple enough.

I am trying to produce a database that will select a swimmers, best time for each event, and will select the overall best time done by any swimmer in the events.
At the moment I am having some trouble with my queries.
When trying to get the query to select a swimmers best time for the events, It will work when selecting min for the time field and including the following fields:
Forename
Surname
Stroke
Distance
Age group
Gender
However I also wish to include the name of the swimming pool the time was done at and the date at which it was achieved. My problem is that when I add these fields into the query, it looks for the swimmers minimum time in the event, on the date, and at the venue and consequently comes up with all the times the swimmer has done, rather than just the best ones.
I would Really appreciated if anyone had any suggestions as to how I can get over this problem
Thanks in advance

hi all,
I've got one question regarding dates.
I've already make the form to show the count of records by using query according to the start and end date selected by the user.
What I want is when I open the form, it should show the results of count between the minimum and maximum dates inside the data table. It means I want to show the count result without date specification that is the total count from all records of the whole table .
Can anyone help me how can I make it?
thanks a lot in advance.

I am trying to set up a calculated field in one of my form querries, using expression builder.
In one of my source tables I have 4 date fields called Inspection date 1 to 4
I need the lowest date among those inspectinos which are in the future (next inspection) If all 4 dates are in the past or Nulls, the function should return the current date. The logic of the expression could be:
MIN(MAX(D1,Date()),MAX(D2,Date()),MAX(D3,Date()),M AX(D4,Date()))
How can I do this in expression builder?
The built-in functions DMin and Dmax work with single field arrays, witch would be perfect if the database were properly designed, but now I dont have the power to change this.

Expressions in Access have given me some trouble before. Mainly due to inexperience. I hardly ever work with them. What I am trying to do is make the default value of a form textbox control the minimum value of a field A in a table A. The datatype of Field A is Date.
So far I've got:
=Min([table A].[field A])
In the Default Value of the form's property sheet, but this just returns a blank value. I've had a look in the table and there is no value that is blank in field A.

When we browse through records in a subform we store the records in the database.When we want to delete a records for example the third record from the five records always the first records will be deleted. How can we delete the records where the cursor is at? When we are at the third record and press the delete button the third record from the list in the subform should be deleted.
Code:
Option Compare Database
Dim FocusBln As Boolean
Private Sub Identificeer()
Me.[Datum Aangemaakt].Visible = True
Me.[Datum Aangemaakt].SetFocus
If Me.[Datum Aangemaakt].Text = "" Then
