Enforce Minimum Record Count

Jun 1, 2007

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.

Count Records Between Maximum And Minimum Date

Feb 24, 2008

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.

Enforce Relationship Rules As If Deleting Record

May 25, 2006

Hello again,

Does anyone know if this is possible and is there an easy way to set it up?

My db has many relationships, hence if you attempt to delete a record from the table, it will not allow it if there are related records.

This is great, however.

My intention is to disable any record deletions. Instead, once a record is no longer live, the status of that record is set to disposed,exipired, etc.

I want to force the same rules as if attempting to delete this record but set to the status field.

Example message.
ie, Warning! You cannot dispose of this PC. There a related records in the Software License and Contracts Tables. Please reassign them and try again!

Any clues would be great.

Thanks All.

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.

Queries :: Using Count And MIN Together To Retrieve Only MIN Record With Count

Aug 16, 2015

I have a table that has 5M+ accounting line entries. Below is an example of one accounting journal in the table.

BUSN_UNIT_IJRNL_DJRNL_ICNCY_CMONY_A
CB0014/07/20140002888269323AUD16797
CB0014/07/20140002888269323AUD-16797
CB0017/07/20140002888269323AUD16797
CB0017/07/20140002888269323AUD-16797

The journal ID above was an accounting entry, debit $16,797 and credit $-16,797. because it was entered as a reversing journal in the system, the table has captured the Journal ID with 2 dates. For my purpose i only want the one date (MIN) date, the total amount of the journal (either the debit or credit amount 16,797) and the total number of lines the journal ID has so in this instance I want the count to be 2 and not 4.

Right now this is what i get

BUSN_UNIT_I JRNL_I CNCY_C SumOfMONY_A CountOfJRNL_I MinOfJRNL_D
CB001 0002888269 AUD 0 4 4/07/2014

This is the output i would like

BUSN_UNIT_I JRNL_I CNCY_C SumofMONY_A CountofJRNL_I MinOfJRNL_D
CB0010002888269323 AUD16797 2 4/07/2014

Im thinking with the total sum because theres debits and credits is there a way to do the absolute value of the journal MONY_A then divide by 2?

current SQL
SELECT [One Year Data Lines].JRNL_I, [One Year Data Lines].CNCY_C, Count([One Year Data Lines].JRNL_I) AS CountOfJRNL_I, Min([One Year Data Lines].JRNL_D) AS MinOfJRNL_D, [One Year Data Lines].BUSN_UNIT_I, Sum([One Year Data Lines].MONY_A) AS SumOfMONY_A
FROM [One Year Data Lines]
GROUP BY [One Year Data Lines].JRNL_I, [One Year Data Lines].CNCY_C, [One Year Data Lines].BUSN_UNIT_I
HAVING ((([One Year Data Lines].JRNL_I)="0002888269") AND (([One Year Data Lines].CNCY_C)="aud"));

Hi,

I opened the relationship window to do the relationships among my tables; however, the check box 'Enforce Referential Integrity' is disabled. I don't understand why is that? And is there anyway to change it?

Also, where should relationships be implemented? is it the FE or BE?
Any help will be very much appreciated.

How To Enforce Relationship Integrity Of SQL Tables From MS-Access?

Feb 12, 2005

Hello everyone. I'm not sure should I post this question here or at SQL Forum? However, my problem is this. I have 2 Tables, Table1 has AutoNumber as primary key, my second Table2 has index key field. I have one-to-many relationship on those two fields, with enforce referential integrity, cascade update and delete

The access program works fine until I upsized to SQL server. [u]Then I was unable to perform cascade update or delete. I have check SQL table (which I have little knowledge about) and seems to be okay, the relationship exists. But at ms-access I was unable to make the cascade update and delete.

I appreciate any help �. Thanks.

Relationship Window, Enforce Referential Integrity Greyed Out

Mar 29, 2007

Hello..

I have a simple database of 4 tables.

luTblJobTitle
JobTitleID (pk)
JobTitle

luTblReason
ReasonID(pk)
Reason

tblDateReason
DateReasonID(pk)
EntryNumber(fk)
Date
Reason
Entered

tblEmpMain
EntryNumber(pk)
EmployeeNumber
Etc//

I have a 1 to many setup between tblEmpMain and tblDateReason.

When I try to setup the relationship between the "reason" field in tblDateReason and luTblReason, Referential Integrity along with the other two check boxes are greyed out.

It still shows one to many but it will not let me enforce referential intergrity.

Why is this? Did I setup the database wrong? Or am I trying to do something I shouldn't be doing??

I have attached the db.. It is split with both the backend and the front end.

I have build a database with which I can create quite a lot of reports. When creating them I run out of memory with run time error "2004".

When investigating I detected that a lot of memory is used when creating the reports in PrintPreview mode. When closing the reports the memory is not automatically freed.

Is there a way to enforce garbage collection? Local variables of called routines I set to Nothing.

Minimum Value For A Report Field

Dec 18, 2006

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?

How do I do it???

Return Minimum Value Within Group With ID

Sep 7, 2007

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.

Minimum From Multiple Tables

May 17, 2013

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.

Identify And Assign Value To Minimum?

Oct 29, 2012

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.

Chart Changing Scale Minimum.

Aug 23, 2007

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.

Displaying Records With Minimum Values Only

Mar 23, 2006

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.

Find Minimum Of Dates From Different Tables?

May 1, 2006

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:

Minimum Difference Btwn. Dates

Nov 2, 2006

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 !!
