Substraction Of 2 Records With 1 Record With No Data

Jun 23, 2005

This is a code I used for a stock control form:

"Balance" =[QuantityReceived]-[Stock record table Subform].Form!SumQtyIssued

It is just a simple substraction between a record from a field and a sum of records from an another field contained in a subform.
The code is working fine apart for the following situation:

If there is no data, yet in the subform;the value for the "Balance" which should be Just equal to [QuantityReceived] appears for 1/2 a sec and disappear!!????

Just now, my knowledge is pretty poor with codes but what i guess is that Access start the calculation fine, then realised that there is no data in the subform and then cancel the calculation.
How can you set the value of a field to 0 or cancel that part of the equation if there is no record for that field?

Forms :: Copying Data To A New Record - Skip Null Records

Aug 13, 2013

I've created some code that enables a user to copy an existing record to a new record, which looks like this:

Private Sub btnCopytoNewRecord_Click()
Dim Salutation As String
Dim First_Name As String
Dim Surname As String

'Copy fields to variables
Salutation = Me.Salutation

[Code] ....

This code is working fine, until it hits an empty field, and then I get an error message: Run time error '94':

Invalid use of NullIs there some code I can use to tell it to skip any null fields?

Modules & VBA :: Delete Of A Record From A List Of Records In A Subform Deletes Wrong Record

Jun 28, 2013

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

Queries :: List Of Dates And Records With No Matching Record OR Existing Record With Higher Date

Nov 24, 2014

I've been asked to get some information from my database and I'm a bit stuck.

I have a list of refunds in tbl_main and each one includes a dateReceived. I make a record in either tlk_located, tlk_unableToLocate or tlk_bulk depending on the outcome when we're trying to send the money back to whoever it belongs to. Each table has a time stamp (named locatedTime, unableTime and timestamp respectively) field

My manager wants me to report how many entries were unworked on each day in the year, and what the value of them was. An entry is unworked if there is no entry in either of the 3 tables.

So I need a query that lists a range of dates, and for each date counts the number of entries where tbl_main.dateReceived is <= to that date and either has no record in located,unable or bulk or has a record with a timestamp > than the date. (It has been processed now, but hadn't been on the date we are looking at)

I can manage a query that looks at a certain date that it prompts for on each run:

Code:
SELECT Count(tbl_main.trust2PK) AS CountOftrust2PK, Sum(tbl_main.amountRefunded) AS SumOfamountRefunded
FROM ((tbl_main LEFT JOIN tlk_located ON tbl_main.trust2PK = tlk_located.trust2FK) LEFT JOIN tlk_unableToLocate ON tbl_main.trust2PK = tlk_unableToLocate.trust2FK) LEFT JOIN tlk_bulk ON tbl_main.trust2PK = tlk_bulk.trust2FK
WHERE (((tbl_main.dateReceived)<=[cutoffDate]) AND ((tlk_located.locatedTime) Is Null Or (tlk_located.locatedTime)>[cutOffDate]) AND ((tlk_unableToLocate.unableTime) Is Null Or (tlk_unableToLocate.unableTime)>[cutOffDate]) AND ((tlk_bulk.timeStamp) Is Null Or (tlk_bulk.timeStamp)>[cutOffDate]));

I would like a query that lists all dates in a range, and shows the same information for each day listed.

Data Entry - Auto Fill Data For Exisitng Accounts In Records

Mar 9, 2006

First I would like to give thanks to all the knowledgeable folks here who have helped me with my DB to date. It is working and every one is very happy and I have learned a lot.

So now I would like to add some more functionality to this existing project.

My DB is for data input of customers for a drawing. It has the following fields: Id, account number, first name, last name, date/time, score1, score2.

I t is taking a great deal of time for the users to enter in hundreds of entries a day. Most of the entries are customers who are already in the DB. I would like to get the fields to auto fill the data for existing customers say after the account number is entered. So after you put in the account the name and any other pertinent data would shows up saving users from typing it in again.

The first problem I am having is that this is still a data entry form and I can’t figure out how to be able to see the account information and still add new data to the record? The new data is a daily score they get.

Second I haven’t figured out how to call up the customers information from just the account field.

I’ve googled this and haven’t found anything terribly helpful.

Display A Record Once If Data In Two Fields Have Matching Record

Nov 4, 2005

Hello eveyone . . .


i am attempting to create a VERY complicated query . . . it's sort of confusing:

I recieve data from an outside source and it is up to us to format it for our own analysis . . .
i have fields:

MethodCode..... AccNo .....PatientName.....MR..... TestCode ..... etc, etc

The fields we want to focus on is "AccNo" and "TestCode"

Now i want to filter based on this condition:

If "AccNo" AND "TestCode" BOTH have duplicate data in a record. Show that record only once. Remember. . . "AccNo and TestCode, both these fields have to have duplicate data in a record.

Example:
MethodCode..... AccNo .....PatientName.....MR..... TestCode ..... etc, etc
CAPT.....M566679.....John Blue.....123456.....CBCA
CAPT.....M566679.....John Blue.....123456.....CBCA
the example above should only display once because of the repeated AccNo and TestCode

Example:
MethodCode..... AccNo .....PatientName.....MR..... TestCode ..... etc, etc
CAPT.....M566679.....John Blue.....123456..... CBCA
CAPT.....M566679.....John Blue.....123456..... LIPID
the example above is just fine because the TestCode is not matching

How do i create a query to accomplish this? someone please help, i've had troube with this for the passed couple weeks . .. .

Check Data On Leaving A RECORD- Record, Subforms And All

May 24, 2005

I have an application that enters candidates in, who apply for a job.

I found that I can enter a candidate in, and if I dont enter at least an address type or phone type ( giving that candidate an address record, albiet a blank one (just a type of address) and a phone record) then the candidate wont have a sub record for addres or phone at all.

This is hurting my reports. They are set to pull the primary address and phone only, as we dont need to have 2-3 contact information for a candidate on a report This is how I found out that I had blank address and phone for some test records. I need to be able to check when a person does a number of things, that at least the combos for phone type and address type have been chosen as something. This will ensure that they have a primary address and phone, as I have code that takes care of all that. I tried putting the following code in the form's before update, but since it is calling to a subform, the minute I tab TO the address combo, I get the message. The form is updating before I get the chance to skip the field.


Here is the lay out. A user can enter in candidate, their address, phone, application and activities. Address, phone, applications and activities are all sub reports on a tab control. The user should be able to move freely within any record, and only be bothered when they try to leave, if important information is still empty. I dont want to control how they enter ('you must enter this first!' lol) just that they do enter it in the end.

What I want to do is check when the user is leaving a record.(closing form, going to another record, clicking the search button that opens another form etc) if either combo is empty (no primary contact info) then it gives the message and goes back to the combo that is empty.

Here is the code I have. If anyone can help me find the right place to put it, I would really appreciate it. Thank you,



If IsNull(Me.[subAddressEntry].Form![cmbAddressTypeID]) Then
msgbox "You must enter an Address"
Me.[subAddressEntry].Form![cmbAddressTypeID].SetFocus
Cancel = True
ElseIf IsNull(Me.[subPhoneEntry].Form![cmbPhoneTypeID]) Then
msgbox "You must enter a Phone"
Me.[subPhoneEntry].Form![cmbPhoneTypeID].SetFocus
Cancel = True
Else: Cancel = False
End If



If I can't figure this out, I am thinking of making a new address type and phone type. Call it "none chosen" and then make that a default selection. Then one would always be chosen...I think. I would like to avoid that though.

Thanks again.

Forms :: How To Move Around From Record To Record Collecting Corresponding Data

Dec 24, 2014

The school director is going to input a date (by default today) and a subform will display all of the students who started before that date and haven't been closed as of that date. Next to each name, there will be 4 radio buttons (present, absent, holiday, hospitalized), which by default will be set to present. The director will go down the line, only needing to click when a student isn't present. At the end, she'll push a save button and the new records will be added.

My proposed method:

1. When the textbox with date input is changed, the subform (or just form and I put the textbox in the header?) will populate itself with a query based on student names whose corresponding startdate and enddate work with the inputted date.

2. The subform will be in continuous view so that it kinda looks like a data sheet but it has radio buttons rather than just spreadsheet cells.

3. When the save button is pushed, some visual basic code in the background will look at record 1, grab the student name and selected radio button value, and add a new record to the AttendanceRecords table with the name, attendance type, and date. Then the code will move to the 2nd record, rinse and repeat until it goes through all of them.

Questions/problems:

1. At its core, is this the Access way of doing something like this? Is there a simpler, more efficient, or generally smarter way of doing attendance?

2. How is step 3 going to work? I can look up how to add new records to a table, but I'm not sure how to move around from record to record collecting corresponding data.

3. Since the AttendanceRecord table uses studentID and typeID rather than actual names and actual attendance types, what's the easiest way of adding the new records with that data efficiently? I'm thinking of making the RecordSource of the subform some sort of linked up set of tables such that if I'm looking at record 1 and the name in the textbox on the subform is "Bob" I can just reference studentID in the background without needing anything on the form at all with studentID?

Forms :: Auto-fill New Record With Data From Last Record

Feb 14, 2014

I have been searching all day for a solution. This is my first time using Access so a lot of this goes over my head. I'm currently running Access2010. I have a form that I am using for when people take office supplies and we can generate a cost per department. All of the Tables, Query and Reports are set up already and surprising work. My form fields are:

Date Created (automatic current date)
Quantity
Item Code (Combo Box that shows Item# and Item Description)
Initials
Department (Combo Box that shows Dept# and Dept Description)
RefCode
Remarks

I am trying to get it to where when I enter a new record it will autofill with all fields expect "Item Code" from the previous record until I change it.

Queries :: Add Previous Record Data To Next Record

Apr 11, 2013

I need to add two previous record fields together in a query. I have attached a picture to illustrate.

The "StudyYears" filed is the primary key of the table the data is being pulled from. The zero's are placeholders for the sum of the previous record's data.

RunningBalance is calculated as follows:

Code:
RunningBalance: IIf([a].[StudyYears]=[ReserveParameters]![StartingBalanceYear],CCur([ReserveParameters]![StartingBalance]),0)

Bal is calculated as follows:

Code:
Bal: [AnnualContribution]+[InterestIncome]+[Inflation_Adjusted_Expenditures]

How to go about adding the two together as in the picture?

Is there a way to do this relatively fast, as well as keeping the query updateable?

Tables :: Move Data From One Record To Another Record

Aug 12, 2013

I'm trying to get a DB to move records simultaneously using a command button. The records are setup with check boxes for example: one column has a check box for 1 Year Ratio the next column has a check box for 2 Year Ratio and the third column has a check box for 3 Year Ratio.

How can i move the information out from 3 Year Ratio into another table and then move 2 Year Ratio check into 3 Year Ratio check box and 1 Year Ratio check into 2 Year Ratio check box by using a command button.

General :: Update Record ID To Another Record ID In Same Table And Update Related Records

Aug 22, 2013

I have a table called tblCompanies. When a company acquires another company, I need a method by which the acquired company's CompanyID (PK) can be updated to the new company's CompanyID (PK). I also need to be able to update all related CompanyIDs (FKs) to the new value in related tables.

In cases in which the new company does not have an existing record, there is no problem: the company name simply gets changed to the new company and the existing CompanyID is maintained. I then use an audit table and Track Changes function to keep track of the company name data and a union query to keep the old names in the selection lists.

The problem is when both companies already have existing records in the table.

So, let's say I have records for Company A and Company B. Company A merges with Company B and Company B is now the main record. What is the best, simplest and easiest way to update the CompanyID (PK) from A to B and change the CompanyID (FK) to the new value in all related tables?

I am envisioning a pop-up form that directs the user to select the new company and then an update query happens behind the scenes... but exactly how does the criteria for the update query get selected and how do all the related tables get updated? My vba skills are pretty basic, will I need extensive coding to do something like this?

Deleting Records That Have Been Checked Or Adding A Record After A Checked Record

Jul 20, 2005

Hi,

I was wondering how to delete records that have been checked (through a checkbox) in a form...

Also, I want to add a record after the record that has been checked. I only want this ability to add records available if only one record is checked. Otherwise, if more than one record is checked, the "Add Record" button would be disabled.

Any help would be much appreciated.

TIA.

Merging 2 Records Into 1 Record

Aug 24, 2006

Can anyone help me with this one ?

Attached is a spreadsheet showing data from an Access table. The Ivd Id field has produced 2 records.

I need to show this detail on 1 row. I have tried using crosstab queries to do this, but there a lot more fields than the ones shown and the processing required is too much.

I have colour coded the data on the spreadsheet to show the 2 records for Ivd Id =36926 (rows 2 and 3 on the spreadsheet), and how they would need to appear in an access query or table (row 16 on the spreadsheet)

Moving Record Information To New Records

Dec 29, 2005

Hi, found this forum looking for an answer to this question. Hope someone can help.

I'm trying to build a database that tracks electronic components. Mostly the database tracks location movements, but also repair issues and other possible changes. I'm thinking the best way is a database that has a record for each move, and any other changes are included in each record.

My question is, is there a way I can easily have the current information be propogated over to a new record, where it could then be modified? Example: I'm looking at a record of an item that was just returned to me. I would like to click a button on the form which would create a new record, then move all currently displayed information into that record.

Thanks for any help.

Delete Record Deletes Other Records

May 11, 2006

I have something very bizarre happening that I cannot figure out.

I have a form with a subform on it. These are not linked. On the first form is one combo box, the records in the subform are requeried every time the combo box changes with the criteria for the subform based on the selection in the combo box.

I haven't got these linked because I also have an Edit option group selection on the main form which changes the subform from Data Entry = False and AllowAdditions = False to Data Entry = True and AllowAdditions = True. This allows me to use the form to enter new records or to edit existing ones by changing the edit mode.

I also have a delete button on this form with the generic code to delete a record:

DoCmd.DoMenuItem acFormBar, acEditMenu, 8, , acMenuVer70
DoCmd.DoMenuItem acFormBar, acEditMenu, 6, , acMenuVer70

The record source for this subform is a primary table on the one side of a one to many relationship.

When I am in the new record mode (Data Entry = True and AllowAdditions = True) and I delete the record I am currently entering it works as expected.

When I am in edit mode (Data Entry = False and AllowAdditions = False ) and I delete the record I am on. It deletes the record but any record in the many side (the secondary table with the foreign key) is also deleted as well. Now I'd expect it to delete the foreign key on the many side and wipe the field but this actually deletes the whole record the foreign key is in from the secondary table.

I have checked my relationship set up for these tables and they are fine:

One To Many Relationship
Referential Inegrity Checked
Cascade Update Records Checked
Cascade Delete Records Checked

I get the usual access warning telling me it is about to delete one record. usually you would also expect the warning to include the comment about this deletion will also delete any related records in other tables, but I don't get that.

I cannot for the life of me figure out why the whole record from the secondary table is being deleted and not just the related field.

Does anyone have any ideas?

I hope I have explained it properly. (Tis always hard to put into words a problem)

Thanks in advance,

Daz

Queries :: Merging Records Into One Record?

Apr 9, 2015

My database was working fine before there was an update to my external data source.

This was my original Append Query

INSERT INTO RLCR4000_CODED ( FY, PayPeriod, ProjCode, DelTask, RegHrs, OTHrs, TotalHrs, FYTDTtlHrs, ProjDesc, TtlCost,
FYTDRegHrs, FYTDOTHrs, FYTDTtlCost, TaskDesc, EmpName, ORG, EmpId, CostCtr, PPBegDate, PPEndDate,
Level2Nodes, Level3Nodes, Level4Nodes, Level5Nodes, Level6Node )
SELECT RLCR4000_pp5_RAW.[Fiscal Year], RLCR4000_pp5_RAW.[Pay Period], RLCR4000_pp5_RAW.[Delphi Project Code],

[Code] .....

The data source changed and the result is now I have a bunch of "Near duplicate" records. I built this query and found the duplicates:

SELECT [RLCR4000_-_Labor_Cost_by_Organi].DelphiProjectCode, [RLCR4000_-_Labor_Cost_by_Organi].DelphiTask, [RLCR4000_-_Labor_Cost_by_Organi].EmpId, [RLCR4000_-_Labor_Cost_by_Organi].CostCenterCode, [RLCR4000_-_Labor_Cost_by_Organi].RecordTypeCode, [RLCR4000_-_Labor_Cost_by_Organi].FiscalYear, [RLCR4000_-_Labor_Cost_by_Organi].PayPeriod, [RLCR4000_-_Labor_Cost_by_Organi].RegularHours, [RLCR4000_-_Labor_Cost_by_Organi].OvertimeHours, [RLCR4000_-_Labor_Cost_by_Organi].TotalHours, [RLCR4000_-

[code].....

There is a field called "RECORDTYPECODE" that was inserted in the external data source. It has one of four values : R, L, N, C

Ideally this is what I want

WHERE ((([RLCR4000_-_Labor_Cost_by_Organi].DelphiProjectCode) In (SELECT [DelphiProjectCode]
FROM [RLCR4000_-_Labor_Cost_by_Organi] As Tmp GROUP BY [DelphiProjectCode],[DelphiTask],[EmpId],[CostCenterCode]
HAVING Count(*)>1 And [DelphiTask] = [RLCR4000_-_Labor_Cost_by_Organi].[DelphiTask]
And [EmpId] = [RLCR4000_-_Labor_Cost_by_Organi].[EmpId]
And [CostCenterCode] = [RLCR4000_-_Labor_Cost_by_Organi].[CostCenterCode])))
Then R+L+N+C=

NOTE and in some cases the fields are null

I have attached a sample of the data. And the second tab is desired result. I have over 9000 near duplicates so it is imperative I create a formula to merge them
