Filtering For Lowest Date Out Of Duplicate Records
Mar 13, 2008
I have a table that has a list of order information, there are multipule records per order that have information about when the order was processed. There is a day tied to the process time of each record, I need to filter out the duplicate records and get one record for an order, but that one record must be the first process time entry for that order. Anyone know how to make this query? Let me know if this doesnt make sense.
Dear Experts, I have created a database with queries that is working fine, however there are many records that have the same information that can not be removed easily, is there a method anyone knows of that can filter the records produced from a query to remove duplicates? i.e. 'select distinct' but for the whole query after the search parameters have been entered.
e.g. the search query is producing, after the refined search values are entered: 414353p - Fiat - 1.6 - MLS 414353p - Fiat - 1.6 - MLS How can i then apply a filter to automatically reduce these duplicates to just one entry for the whole form?
1 table contains the records I needs to be queried. The result Im looking for is to view all the clients that have a different advisor assigned to a duplicated ssn. - not same advisors assigned to a duplicated ssn. Example of desired outcome. ssn name advisor plan 111223333 joe smith john doe b 111223333 joe smith jane sony c 111223333 joe smith unknown a
I am getting all data. ssn name advisor plan 111223330 Jack Jack john doe b 111223330 Jack Jack john doe c 111223330 Jack Jack john doe a
Ive tried query with using 'first' for the ssn and the advisor still give me all data. Please help me.... Thanks
Table 1 has all the items I am trying to sell with sell by date after which I cannot sell this item. Then in Table 2 I have forecasted sales. So now I am trying to calculate stock consumption to see if I will be left with any stock that I cannot sell.
So now somehow I need to deduct sales forecast from my stock holding but it needs to go by date i.e. consume all stock for Item 1 with date 16/09 before moving to Item 1 with sale by date 23/09.
So based on the attached example, I can see that on 16/09 I will consume only 5 cases from sell by date 16/09 and another sale is 18/09. So that would give me information that I will be left with 95 items dated 16/09, which I cannot sell because they will be out of date.
Ideally I would like also to include the logic that if Item is out of date it would move to the next sell by date.
So in this case sale of Item 1 forecasted for 18/09 (94) would consume the whole stock (50) with date 23/09 and another 44 from date 01/10
For Item 2 I can see that units with Sell by date 30/09 will be consumed on 25/09 and I will start taking stock from next sell by date which is 14/10.
I have a relatively complex update that I need to perform on a table from a form. I have a system that has "games" and "game copies". The game is simply a name of a particular game and the copy is something that has a stock number but a foreign key of the game catalogue number. This means I have several catalogue numbers that are the same in the GameCopy table.
The problem is that I have to reserve a game - not a game copy. When I have made a game available (it has been returned) I have to indicate this in the reservation table. I could have many different reservations for the same game so I need to only update the oldest reservation and indicate that a game copy is available now.
Summary: One "Game" Several "GameCopy" using "Game" as a foreign key Reservation table with possibly several reservations for the same Game - not GameCopy(s)
In other words I have an "Available" field in the reservation table and a "date reserved". I need to create an "Available" (Date()) entry for the oldest DateReserved entry on that reservation table. I could have done it as a boolean but I decided to use a date instead for logging purposes.
Would I use some kind of "Once only" action to make sure that only one of the reservation entries are updated? I really do not know how to proceed with this.
Obviously if I simply:
UPDATE Reservation SET Reservation.Available = Date() WHERE Reservation.CatalogueNo=Forms![Current Reservation].CatalogueNo;
...then it will update all of them. I believe there must be a bit more SQL I have to add or something else maybe.
In my simple database (attached), I need to mass duplicate Tasks and their Notes.
I have three tables: tbTasks (PK: Task_ID), tbNotes (PK: Note_ID), jtbTaskNotes (FKs: Task_ID and Note_ID). jtbTaskNotes is my many-to-many junction table that ties Tasks to Notes.
The main form (fmTasks), bound to tbTasks, has a subform (sbfm_TaskNotes) that displays notes associated with each Task. On themain form,you select which Tasks you want duplicated via a checkbox. The append query (quCopyTasks) will duplicate all tasks that have the checkbox checked. All good there. However, I can't figure out how to also duplicate each task's Notes.
I found Allen Browne's solution [URL] ....., but that only handles duplication of one record at a time, whereas I need to duplicate many records at a time (sometimes 10+ records). How do I go about duplicating multiple Tasks and their associated Notes?
Before you ask "why are you duplicating records?": There are times when tasks need to be re-accomplished and therefore need to have a new record. It's easier to duplicate records than it is to hand-jam everything again.
I have built a qry that initially shows the correct information. For example.
tblContent has 289 records with a Type = Class.
I built a Query to select from tblContent Type = Class and I get 289 records. I add additional criteria of Progress <>"Not Scheduled", I then get 206 records. I then add additional criteria Last Name <>"Demo" And <>"Care" And <>"Support". This brings up 200 records, but the query appears to duplicate each record 3 times. I do not have 3 of the same types of records.
The SQL Statement is below
SELECT tblProfile.LoginName, tblProfile.FirstName, tblProfile.LastName, tblProfile.Organization, tblProfile.CostCenter, tblContent.Title, tblContent.Type, tblContent.Code, tblContent.[Date Assigned], tblContent.[Date Started], tblContent.[Last Accessed], tblContent.Progress, tblContent.[Date Completed] FROM tblProfile INNER JOIN tblContent ON tblProfile.LoginName = tblContent.LoginName WHERE (((tblProfile.LastName)<>"Demo" And (tblProfile.LastName)<>"Care" And (tblProfile.LastName)<>"Support") AND ((tblContent.Type)="Class") AND ((tblContent.Progress)<>"Not Scheduled"));
The qry is named qryPhysical Class. I have provided the link to view the database. Can you help me?
I wonder if anyone can help. I attach a table that is a material list (27000 records). When I add a new material I want to be able to see the last part code I created for a particular supplier.
For example C001, C002 and C003 are for a supplier company called Chapters so I would scroll through the combo box search list in the form for the last one and create a new record called C004. The problem is that E00001, E00002 for a company called Edwards supplies 20,000 items so it's a long way to scroll through to create a new part code called E20001. How can I show in the form what the last part code is for each Supplier?
I attach the form and table as I'm not very good at explaining this, although I have had to delete approx 20000 records as the database was too big to be posted. Any advice/help would be greatly appreciated, many thanks
I have a database to record drawings received. On the form there is a combo box to select discipline (Civil, Electrical, Mechanical) and a combol box to select the volume the drawings are in (Volume 1 - foundations, Volume 2 etc). The disciplines are stored in tblDisciplines with a relationship between this and the main tbldocument. I also have a table , tblLocation which has the volume ref and description. However when I click on the location field it shows me all volumes for all disciplines. What I want is if the first field selected is Civil only the civil volumes are displayed. Can any one point me in the reight direction
This query is to show aging. I have a field for processed date. I have a query that allows a date range to be selected using the Between function.
The query runs and pulls these variables from a form. It shows only those accounts which were processed between those dates.
However, it is also showing all of the accounts that have no date in this field. I need to set it up so that if the field has no date then it doesn't show those accounts.
I've tried Not (is null) for the criteria but that isn't working. I've tried a lot of stuff but nothing seems to work.
i have created a new form based on a database called RptSmp97 from microsoft knowledge DB. My form, as in the sample, calls a report when it is opened and at the same time shows you a multicombo form for filtering the report. In the sample the form uses only text fields, but i need to use numeric and date fields too. I could solve the problem with the numeric combos adding a condition for them, however, when i add another condition for the date it doesnt work. Also, at the end of the code i print the sql and it looks perfect.
here is the code when the apply filter button is pressed....

i am trying to build a marine turbine and parts log and have a problem in satisfying a working rule.
i have 2 tables which i have attached,
table 1 shows the on / off dates that a generator was fitted to a turbine
table 2 shows a general date history of the generator, when it had checks done, fitted, etc
what i would like to do is fit the generator again to another turbine
using a continous form to show the available dates in table 2, i would NOT like to see the dates during the period when the generator was fitted previously as shown in the on / off the dates in table 1.
the working rule being that a generator can not be fitted to 2 different turbines at the same time
can anybody point me in the right direction or assist in how i can overcome this problem
I've created a Form where I enter all my data - then I created a Report to output this data, it includes two buttons to filter based on one category. That's working fantastically well for me.
But now I would like to filter on dates. For example, last 7 days, last 14 days etc - and also give the user the option of filtering between x and y dates. I've discovered this is easily done by right-clicking the date field in the report, but I'd prefer to embed these commands into buttons etc so it's easier to navigate.
I have a rather simple problem that I do not have the time to solve. I have a time series taken at 30 second intervals over 5 months and the records total over 250,000. I only want data from every 15 minutes, so only one out of 30 records. How do I filter the table to extract only the records I need?
how I can modify this code to make it filter results in a combo box by what the user types in to search for.
Private Sub txtSearch_AfterUpdate() With Me.RecordsetClone .FindFirst "[FirstName]=""" & Me.txtSearch & """ OR [Lastname]=""" & Me.txtSearch & """" If .NoMatch Then Beep
Customer: ---------- name | city | salary john| Boston | 14000 billy | Boston | 32000 sam | Boston | 12000 jj | Dallas | 6000 greg | Dallas | 8000 josh | LA | 1200 ally | LA | 600000 bill | LA | 12000 bob | LA | 9800
how can i list the city with the lowest average salary?
I need to find the average salary of each city(should be 3), then choose the lowest from those 3 averages.
I'm using a filter on the form load of one of my forms that potentially would have 3000 records. The idea is to speed the process up a little.
I'm using:
If IsNull(Forms!frmProjectMain!ProjectID) = False Then DoCmd.GoToRecord , , acFirst end if Me.FilterOn = True
Which works fine. However, I'd rather it was the ID with the lowest numeric value that was displayed and filtered rather than the last record chosen. i.e. 1 instead of a random number.
Does anyone know how i'd go about writing code that would tell access to go to the lowest ID to filter?
I have an Excel workbook which I use to extract data from an Access database using VBA. A requirement has popped up to show things from the last week. Unfortunately, I can't just use a Date()-7 query in Access as the start point might be different, so it needs to be based on seven days prior to a date field in Excel.
So, I have a cell in Excel with a date, in this case "16/01/2014". I want to then use that date in my query to say "greater than 8 days prior to to this date". The field is formatted as a date and the variable (DatafileDate) taken from this field and passed to the function is a Date. In my Select query I then have this line to select the top 5 marked as UK accounts in this case:
Code: SearchText = "SELECT TOP 5 * FROM `" & TableName & "` WHERE `" & TableName & "`.`Account`='UK' AND `" AND `" & TableName & "`.`Close Date` > #" & DatafileDate & "#"
Code: #" & DatafileDate & "#" -8
Should mention that the TableName stuff is so the name of the table can be set elsewhere. "Close Date" is the column in my Access query I need to filter on.
I want to find duplicate records based on FirstName and LastName and delete the duplicate. Also, I want to delete any records which have a blank FirstName and LastName.
I have a database that I have secured by using Access 2003 user security. I need for the database to allow the user to login and once they have logged, to open a form and filter out only their open "tickets" - records.
I have a database with 2 tables. Table1:drawing number and drawing title and Table2: date, action, status. Table2 gives the complete history of our internal review process.
I need a report which lists just the 'not approved' drawings. I've been able to add a query which lists the drawings but I loose the complete history, i.e. drawing recieved date.
Is there anyway I can display all the fields but only for those drawings which are 'not approved'
Hi, I need help on my search command. I am hoping to be able to use a combo box or a list box coming from a table as my criteria to use to filter records from a form and present it a subform/subreport upon clicking the command button. Ideally I should have a form wherein I will have a either a combo box or list box for my criteria, a subform/subreport, and a command button. When I select a particular item on the combo box or list box and I click the command button, the subform/subreport would show me records matching only the particular criteria I selected.
I tried using several approach but it's not working, I don't know what I'm doing wrong. Please help me, I am just learning how to do this all by myself.
First Approach: I tried using a list box to list all the countries I have available from the country table and a command button so when I select a country from the list box and click on the command button I will be able to show on a datasheet view only records matching the country criteria. This is the code I used: __________________________________________________ _______________ Private Sub Preview_Click()
End Sub __________________________________________________ _______________ But everytime I click on the command button Preview, I am always asked to enter parmeter value then when I type the country that's when it shows the record in forms format matching the criteria country but when I dont type anything and click ok, it just shows a blank form and indicates it's filtered but no record is showing. But I click cancel, it shows a Run-time error '2501'. why does it still have to make me type the parameter if I have selected it on the list box already?
Second Approach: On the form: I used a combo box, a subform/subreport and a command button. On the combo box I have to show different countries available on my country table. on the subform/subreport I have used my a form created from a query. I want to select from the combo box a particular country and used it as my criteria to filter the records I have on my subform when I click on the search command button. I tried following the sample given by gromit but it doesn't want to work on my database.
This is the code I followed: __________________________________________________ _______________ Private Sub btnClear_Click() Dim intIndex As Integer Me.cmbCountry = 0
End Sub
Private Sub btnsearch_Click() Me.frmqrybyCountry1.Form.RecordSource = "SELECT * FROM qrybycountry" & BuildFilter
Me.frmqrybyCountry1.Requery
End Sub
Private Function BuildFilter() As Variant Dim varWhere As Variant
varWhere = Null ' Main filter
'Check if there is a filter to return... If IsNull(varWhere) Then varWhere = "" Else varWhere = "WHERE " & varWhere
' strip off last "AND" in the filter If Right(varWhere, 5) = " AND " Then varWhere = Left(varWhere, Len(varWhere) - 5) End If End If
BuildFilter = varWhere
End Function __________________________________________________ _______________ After selecting on the combo box and click on the command button it just shows all record. It doesn't seem like it is reading what I selected from the combo box as my criteria to filter the records. What could be I be doing wrong? Honestly, I dont understand what is happening to the code here especially the BuildFilter function.
Please help me, I would really want to figure this problem out. Thank you so much.
