I am trying to use DCount to count the number of records (speakers) for each session. Not being very savvy with DCount, I copied code that I had working for another instance of needing to count the number of records.
My query has three fields
Query used: Web/PrintReport_qry
Session Id - number
Speaker - string
I have answered my own question so I thought I would share as I couldn't find the solution in any posts. I confess that I don't understand why my results were wrong, but I managed to get them right. :rolleyes:
When using Dcount in a query, I was getting results which did not match the query results. For instance:
Phase_2: DCount("Project_Phase_ID","tbl_Prj_Details","Project_Phase_ID = 2") gave an answer of 27 when there were in fact 41 projects in that phase.
Searching the forum I came accross this:
Count() always counts the entire domain.
So, Dcount is not counting the record set of my query but something else. I have 4 tables in the query and no idea what domain my dcount was looking at. I presume the various join types were messing with it somehow. :confused:
To get round this, I stripped out the Dcount expressions and changed the query to a make table. I then used the created table as the basis of a query in which I had my Dcounts. The dcount results now agree with the query recordset. :) :) :)
Any background on the bits I clearly don't understand will be gratefully received. I hope this helps someone else sometime.
I have a query that uses "<>" to find records that are not equal between 2 tables. The formula looks like this:
<> [tblWorkPerformed]![ID]
It works fine as long as there is only one record in tblWorkPerformed, but once I add a second record I get the records I dont want plus the records I do. The records I do what are there twice. I found how to only get single records of each, but it still desplays the records it should not. I tried a dummy database, and it does the same thing. Do I have something wrong or is this just not possible.
I am trying to count the number of records in the query result and for some reason, it's not coming up with a number. This comes up "1E+0.."
not sure what's really going on, but this started happening after i converted all my data from excel. However, records come up when i actually go run the query and not from the form.
here's my formula from the form: =DCount("[Queue]","qryODFData","[Queue]= 'NBCT'")
I'm sure some of you have ran into these problems after data conversion.
I have a unique query which lists all the films that we are screening over the next 3 months. I have added a COUNT field so that I can see how many of each films we are screening.
The problem is that i get duplicates of some films - and this may be because we may hold several copies of some films. I have attached two images which might explain this better!
What I could do with is knowing how to make it so that i get a list of films booked and how many of each, regardless of which copy of the film is used.
The SQL is:
Code: SELECT DISTINCTROW dbo_Films.[film name], Count(dbo_Films.[film name]) AS [CountOffilm name] FROM ((dbo_Films INNER JOIN dbo_filmCopies ON dbo_Films.ID = dbo_filmCopies.tblFilms_ID) INNER JOIN dbo_EventsFlicks ON dbo_filmCopies.ID = dbo_EventsFlicks.filmCopyID) INNER JOIN dbo_Venues ON dbo_EventsFlicks.venueID = dbo_Venues.ID WHERE (((dbo_EventsFlicks.datefield)>=#8/1/2015# And (dbo_EventsFlicks.datefield)<#1/1/2016#)) GROUP BY dbo_Films.[film name], dbo_Venues.southhub, dbo_Venues.northhub, dbo_Films.Specilaised ORDER BY dbo_Films.[film name];
I am trying to set up a statistics summary of my database. Part of this is the number fo records counted in a query for various queries. I found this on the forum:
To show the number of records returned by a query, you can use the DCount() function.
Put a text box on the form. Put this in the Control Source property of the text box (using the correct query name):-
=DCount("*","queryName")
I have made a blank, unbound form and added a text box using this syntax above (with my query name).
However, I get an error in the box '#Name?' when I run the form.
If DCount("strTripcode", "tblTripreports", stLinkCriteria) > 0 Then 'Undo duplicate entry Me.Undo 'Message box warning of duplication MsgBox "Warning Tripcode " _ & SID & " has already been entered." _ & vbCr & vbCr & "You will now been taken to the record.", vbInformation _ , "Duplicate Information" 'Go to record of original Tripcode number rsc.FindFirst stLinkCriteria Me.Bookmark = rsc.Bookmark End If
Set rsc = Nothing ************************************************** ******** I found this code on a site and I adjusted it for my situation. However I keep getting Error 2501 'You canceled the previous operation'. Even after reading all posts about this subject I still haven't figured out the problem.
I have set up a form to run a query with the criteria linked to the options/drop down menus on the form. I am able to search for criteria set out in the combo boxes. However, what i would like to ensure is that if the drop down boxes are left blank the results will be to show 'all' results for that field.
I ahve declared custCount as an integer and id as a string that comes from the user form (id = me.CustID) and trying to count the number of matching records in the recordset (rst) using the following:
custCount = DCount("[customerId]", rst, "[customerId] like '" & id & "'")
I'm getting a type mismatch error on the DCount statement?
i keep getting an error "could not delete from specified tables"
I have a table with this data
Main table bub|12345|1 bub|45678|2 bub|91011|3
Child Table bub|45678|2
result in Main table
bub|12345|1 bub|91011|3
match from child table and delete from main table.. but i keep getting error "Could not delete from specified table main table has unique records. and it is primary key..
My DCount statement is not finding a record that I know is there.
Code: Private Sub Transfer_WN_Books_Click() Dim ST As String ST = "H" If DCount("*", "Books", Author = " & Me!AuthorID & " And StatFlag = " & ST & ") > 0 Then DoCmd.Beep End If End Sub
I am building an access database for my college project and I essentially have a quotation form that when I click a button 'Convert to Invoice' it creates a new record in the invoice table and then creates new records in the invoice details table which match the quotation details table. This is working as it should but for only the first 2 customers in my customer table?
On the quote form I have a combo box which is linked to the customer table and updates the quote table based on the selection. If I select customer 1 or 2 and click 'convert to invoice' it works and opens an invoice form based on the inserted data however if I select any other customer it returns an error that the record wasn't added to the table due to key violations?
As far as I can tell I am not trying to update the primary keys in the Invoice Table or the Invoice Details Tables.
It is basically a DCount, and it should find records, but returns 0 all the time. My code is:
Code:
Function cntkit(sftd As Date, sftn As String, typid As Integer, specpaint As Boolean) As Integer 'Counts jobs kitted during shift given by sftd and sftn Dim timeformat As String timeformat = "#mm/dd/yyyy hh:nn:ss#" 'need this, to convert it to US datetime format cntkit = DCount("[JOB]", "Archive", "[Type] =" & typid & " And [Autfinish]=False And [SpecPaint] =" & specpaint & " And ([Kit] BETWEEN " & Format(sftstart(sftd, sftn), timeformat) & " AND " & Format(sftstart(sftd, sftn), timeformat) & ")") End Function
sftstart and sftend are functions which are returning dates. The funcion works fine if I omit the Between part of the criteria. So the problem is in that part.
I have a report that I am trying to complete based on several queries. I am trying to count the number of records based on certain criteria and using the following DCount.
=DCount("[Calculated time]","IPG1","[Calculated Time] <= 0.04" And [Ship-to party] In ("SN00207PJZ","SN09162XXX","SN09324XXX"))
I want to count the number of IPG1 records that are under .04 and have the Ship-to party of the ones listed. I have tried everything that I can think of to get it to work but can's seem to get it to. I figure it's something easy but I don't see it.
I am trying to count the number of records in a subform where the text box (txtFinal) = RPR-RPR & RTN. The subform is called PartNumbers. The table name the subform is bound to is named Completed.
I tried using =DCount("[Part Number]","Completed","[Final] = 'RPR-RPR & RTN'"). That is counting the total number of records in the table, not the total number of records in the subform. How do I get it to count the total number of records in the subform?
I used a DCount however this does not separate the employees. Currently using Count Of Visits: DCount("[Duration]","Test Query","[Duration]<20 AND [Employee ID] = [Employee ID]")
I am trying to count the amount of records that were created and closed for last month but I am having problems inserting the correct criteria along with the DCOUNT syntax. DCount("*","obsvnofilterqry","(Date_Closed)=MONTH( Date())").Works fine but figuring out how to get the amount of Date_Closed for last month is proving tricky.
I have a large table (>1M rows), and I have searched various forums for a way to add sequential numbers by Group. The query I have works, but since it's a large table, I broke it up, and did everything what starts with A-E, the F-Q, etc, and appended to a new table.
This query works, on anything that starts with the letter D or later... A-C will not work.
Basically, the source table is a list of all combinations of Part_ID and UPC_Code. I am trying to number the UPC_Code field, per Part_ID. There is an AutoNumber field (ID) that is in the table as well.
This is the SQL. Query1 is the query that is being executed, so the DCount is within this same query, if that makes sense.
Code: SELECT tbl_upc.ID, tbl_upc.Part_ID, tbl_upc.upc_code, DCount("[Part_ID]","Query1","[Part_ID] = '" & [Part_ID] & "'")-DCount("[Part_ID]","Query1","[Part_ID] = '" & [Part_ID] & "' AND [ID] > " & [ID]) AS Seq_Num FROM tbl_upc GROUP BY tbl_upc.ID, tbl_upc.Part_ID, tbl_upc.upc_code ORDER BY tbl_upc.ID;
The results of this query are that all Part_IDs that start with A through C produces a Seq_Num of 0, but any that start with a "D" or later number correctly - in other words, the first instance of a particular Part_ID is 1, then 2, and so on up to the total count of that Part_ID.
