Dynamically Update Field Of A Current Record Based On Previous Record
Apr 30, 2007
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.
btw, although values will always be in order they may not all be output, so it's not just case of odd, even, odd, even (that would be too easy!)
I can retrieve the Previous Record's GroupNo value (via a function) in another text box and compare current GroupNoID with this in the Format Expressions and manage to change the colour, but it won't sustain this new colour for the subsequent same GroupNos, obviously as the values have changed.
So how can I....
Change the colour when the value changes. Keep this new colour until it the value changes (increases) again.
I'm struggling with a query to evaluate current and prior record data. I have a query producing 5000 records. I need to group records by Case ID and compare current date record to previous date record to determine if a team and worker name has changed during the year. I need to count how many times a cases is transferred to and out of a particular team from the beggining of the year. i.e., On 1/1/2014-Team1 has an inventory of 500 cases.
During the month 25 cases are transferred into Team1 and 15 cases are transferred out of Team1. So on 2/1/2014 Team1 begins with an inventory of 510 cases. Throughout the year cases come and go from and to Team1 each month so need to figure out how to create a query to count each change. See attachment displaying how the data is listed and how I invision it to work with the In/out column counts.
Specifically, at the begginig of the year (1/1/14) for case ID 1003 you can see it belongs to Mary in Team1 for January and February. Then in March the case is transferred out and went to Joe in Team 3. So for Mary a "-1" is recorded as a negative count for that Case ID. If later in the year the case is transferred back to Mary a "+1" would be recorded. Respectively evaluated for each of the 5000 records to get a total count for each of the teams by Case ID throughout the year.
I've started with DLookup, tried comparing current month to previous month using DMax. It works as long as I only select one case ID used in a separate query but if I use the whole subset (5000 records) it fails. I can't figure out how to group each set of case IDs and then apply the query.
I'm trying to update an imported table from an excel spreadsheet with missing details. The table's records are in order so I just need to fill in a blank field with data based on the previous one as shown.
ID Name Location 1 Bob London 2 Larry 3 Harry 4 Jerry Glasgow 5 Paul 6 John Southampton
I need to fill in the location blanks simply with the last location details, so records 2 and 3 with London and 5 with Glasgow. Is this easily done or would I need to pull all the data into an array and work on it there?
I've tried searching for an answer but haven't had any luck.
I'm trying to create something like an online banking view that shows the running balance as each transaction occurs. I have tblTransactions with fields AccountNumber, ItemDescription, and TransactionAmount. I'm trying to create something that shows these three fields and a fourth field with the running balance.
So if I initially deposit $100 it will show the first record with TransactionAmount = $100 and RunningBalance = $100. Then the next transaction will subtract the Transactionamount for the new record from the RunningBalance from the previous record to get the RunningBalance for the new record. So if I make a purchase for $2, the AvailableBalance for that record is $98. Is this possible with a query? Here's a picture to describe what I'm talking about ....
create a macro that automatically fills in the next invoice number in sequence",,I'm assuming this macro would look at the value of the previous record and add a one to itI don't want to use a AutoNumber field as I might need
I have a table of customers who report trouble on their equipment. I would like to compare the date in the current record to the previous record to see if it occurred within 30 days. Can I do this with an SQL query or expression?
I want to get the datediff of the last returned date from vacation and the current vacation start date. But how to get difference from the previous record's date to this current record's date. I want to show date difference in an unbound textbox. I have a contiuous form which shows all vacation list of employees. It shows how many times he went vacations and when he went and when he returned.
I have a Main form that has button that loads a new Pop Up form for entering new data that will display in the Main form. When all the data is entered I click on a button that Saves the data and exits the form and then runs Re-query on the main form returning to the record that was current before the requery.
I have the following code:
Private Sub cmdSaveTradeAndExit_Click() DoCmd.RunCommand acCmdSaveRecord 'Save the current record DoCmd.Close 'Close the current form Dim CrId As Integer CrId = Forms!frmTransactionMainActivePopUp.CurrentRecord Forms!frmTransactionMainActivePopUp.Requery DoCmd.GoToRecord , Forms!frmTransactionMainActivePopUp, acGoTo, CrId End Sub
But I am getting the following error:
Run-time error '2498':
An expression you entered is the wrong data type for one of the arguments
I want subtrack a value on the current record from the previous record and display the result in text box in subform datasheet. This is done during data entry. The calculation works most of the time and randomly it returns the wrong value. I have the code in an after update event after I enter a number. Here is what my code looks like:
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.
This may be a really straightforward one but I cannot seem to find a solution.
I need to run a select query, (for a mailout) then mark the records that have been selected in the query on the main database table with a mailshot code.
Any ideas on how best to achieve this?
I was thinking of making the select query maketable (because I have to export a txt file of email addresses for a mailing list), then add a mailshot code field, then append this extra field to the main table.
The trouble is that I am not sure how to use the query to add this extra field to the maketable & once this has been done, how do I append the values to the original table when the mailshot code field does not exist, can it be dynamically created?
I have a query to bring in values, I need to select 2 rows of data but the criteria is as such:
x= starting value on form
now the row of data must match the following criteria previous row to current row(ref temp)<=x And Current row(ref temp)>xnext row to current row(ref temp)>=x And Current row(ref temp)<x
I have dealt with SQL before but how to do the above.The isolated 2 rows of data will then go into unbound boxes on a form from which I will do intercept and gradient calculations.
I am trying to write some vba code to auto fill a cell's value based on the value of the cell in the previous record (In a datasheet form) i.e. if the value in record one was '1' and the down-arrow key was pressed then the value '2' should be entered into the new ext record
I have written some pseudo-code to show what I am trying to accomplish:
if keydown = down-arrow and current cell contents isnumeric then Cval = current cell contents if current record = last record then create new record move down 1 record set cell value of new record to cval+1 else move down 1 record if cell value = null then set cell value of record to cval+1 end if end if
I am creating a database for an annual golf tournament. Part of this is to allocate players to play off together at certain times.
I have a form bound to a table called tblteeofftimes. This form has five fields (continuous form) - four of which are comboboxes whereby user selects each player for the record (who will play together). The other textbox has the tee off time. the first tee off time will be allocated by user eg 7:00 am.
My problem is I need to update each ensuing record with a new time slot at 7 minute intervals. Rather than have the user populate the form themselves I would prefer this be done authomatically as the user moves onto the next record.
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
I am a relative Newbie so if my question sounds stupid, bear with me:
I have a form with a subform linked to a query.
On the subform i have a checkbox[Recieved] and when checked adds a date to another field [Year] on the subform which in turn updates the record in a table[Orders].
I then click a command button on the form which runs a crosstab query based on the updated fields in the table [Orders].
This works well except for the last record ammended which does not update the [Year] field in the table [Orders]. When the command button is clicked it is still the current record in the subform.
clicking another record in the subform solves this or closing the form and reopening it before running the crosstab query.
Is there an easier way to automate the update? So that the user does not have to select another record first.
I have a form(F_Roll) that runs from a query(Q_roll) which asks the user to input the date. New records are made from this form, and it also allows the user to look at the records from past dates. On this form, my next button creates a new record for that date and fills a field called "RollNumber" with a running counter based on the CurrentRecord. If no roll is present for that date, "RollNumber"=1. If the "Next" button is pushed and "RollNumber"=1, then on the next record, "RollNumber" is filled with 2. If 2 then 3,etc. "RollNumber" is my primary key for the table(T_Roll), and actually, I have the date in front of the counter. The data in "RollNumber" is like "071206-1", "071206-2", "071206-3", "071206-4", etc. What I want to do is have a button on my main form(F_Roll) that will open a new modal, pop-up form on top of my main form that allows the user to enter data for the next record(roll) while still on the current record(roll). I can get it to work if the next record(roll) has already been made. But if I make a new record through the pop-up form and then try to goto the next record I my main form, I get a primary key error about making duplicate primary keys when trying to save the record. The problem is(I think)- The query for the main form has already ran, so it doesn't recognize the new record made from the pop-up form. When the next button is pushed, it is creating a duplicate record(roll) in the primary key. Does anyone have any ideas how to work around this? I am using Access 2003
I have a column "CAT" each time that CAT switches between 0 and 1, I would like my query to auto-create a "grouping" and increment the group by 1. What I am looking for is the output as shown below.
I have a table full of meter readings. I want to have a field called consumption which looks at the reading just entered for that month and then subtracts the previous months reading for that meter which leaves the consumption.
Can I get a formula that can work this out automatically?
I am designing a contact management system and have hit a bit of a wall. I am farily new to Access so please advise if I am going about this the totally wrong way.
I have three tables; Contacts, Companies, Company_Addresses
Contacts: ContactID (P) CompanyID OfficeName
Companies: CompanyID (P)
Company_Addresses: CompanyID OfficeName (P)
What I want is when adding a contact, to have a drop down list in the CompanyID field showing all the companies in the Companies table, and then in the OfficeName field, have a list of only the offices related to the company selected in the previous field.
I can do the first list, but cant work out how to list only data related to the company selected in the previous field. Any help would be greatly appreciated.
I have a small problem: I just want my form to update the current record because I'm opening (with a button) a second form which uses the values of some of its table fields. If I open 2nd form without updating, it will use old values, and if the record I was worknig with is a NEW record, 2nd form simply can't find it because it's not been written! So: 1. I want to tell the button to UPDATE record before opening the 2nd form. 2. In addition, I could want to go to 2nd form DIRECTLY from the same field I want to update and use in 2nd form (through a Keypress event instead of a button), but this is more difficuolt because I still didn't EXIT from the field but I already want to use the text manually updated in the field... any idea?

right, struggling here. Basically I have continuous form listing all the standard letters sent out when I double click on a letter, I need to to run a query for me. The code I have put behind the button is: If ([StandardLetterType] = "Homework") Then DoCmd.OpenQuery ("qryHomeworkClearMailMerge") DoCmd.OpenQuery ("MergeHomework"), , , , , acDialog, Me.[StandardLetterID] DoCmd.OpenReport ("rptHomework"), acViewPreview Else ' end if
and in the query I am first clearing the mailmerge yes/no field out which works fine and then running the merge to put the yes back in the current record so the query looks like this
Its an update query with update to yes for mailmerge and under the standard letter ID i have the criteria [Me].[OpenArgs]
is this completely wrong tried the [Forms!][frmFullStudentReport].[standardletterID] but it kept popping the box up asking for the number.
On the form I have the standardletterID and its hidden but there.
Having a problem with a report, I have a form that i use to enter a new record to my database, what I want to do is put a button at the bottom of the form to print the record (via a report)
If I base this on a record that already exists, it works fine. However, If I have just entered the record the query the report runs off doesn't see the new record. To print that record I have to exit the completed record, then go back in to it and print. My aim is to remove this additional part of the process, I'm sure it's something really simple, but can anyone help?
