Count Matching Records From A Subform. Please Help...
Mar 1, 2006
I need to have the sum of the "matching records" of a subform, exported to a variable of the main form, in order to use it in an if condition.
e.g. "IF a client has brought X? times the vehicle A for a service of type B, THEN do ..."
How do I get the X value in a variable within the main form which presents all activity for all clients (by means of a subform).
I hope this is clear.
Plaese help me, guys. You 've done it before, you're so great!

I have a form where a user reviews information input by another user, once they have done this they sign it off by selecting their name from a drop down list. On this form there is a scrolling message which tells the user how many un-signed entries there are. This works fine until there are 0 (zero) entries to be signed off.
The scrolling message is linked to a count query which basically counts any records that does not have a name entered in the required field. I have done this with ' Not Like "*" '
Like I say it works when there is one or more entries to count, but as soon as there are none the query does not output a zero it is just blank. This is the problem.
I need some sort of statement to say if there are no matching records please display a zero.
Any help would be much appreciated!

All. using 2010. I have a form and a subform. my master and child links are set but when I scroll thru my form; my subform does not change to show the matching records. I do have an unbound search field for the same field as the master and child links. When I type in the search field for a record; the subform does change to that particular record. Do you think that has anything to do with it?

I have a form that has a subform in it, which is another table in it. I want to add the number of fields that are in the subform. What is the best way to do so?
I would like to write a VB script so that a field in the master field = the count of the records in that subform. Any help is greatly appreciated. Thanks.

i want to Count recrods by a pressing a button from a subform.
After counting the records from the subform, it should compare the amount of the records with a number.
The user can put in the number.
The field for the number is called number.
The button is in the form.
I've created the following code.
The Name of the subform ist Abfrage_Vergutungssatze_Unterformular
Code:
If DCount("*", Me.Abfrage_Vergutungssazte_Unterformular) > Me.number + 1 Then
MsgBox "Please recheck!"
I've get an error.
error message: errors when compiling

I have a main form [frmZone] and a sub form (single form) [fromZoneSub] linked master/child by [ZoneID]
If there are, say, 5 related sub form records I'm trying to get a label [LabelCount] on the sub form to say "1 of 5" and as you click through the sub form for the label to change "2 of 5", then "3 of 5" etc....basically letting the user know how many records there are and as they click to the next record know which record they're on.

trying to create a query in which I can select a count across two tables with matching postcodes.
Table 1 : Address database with column called 'STRIPCODE' (e.g. ME8, ME9, ME10)
Table 2 : Area Code table; each column has a list of area codes to match to the STRIPCODE column. (e.g. MEDWAY column will have all of the relevant area codes)
I would pretty much want a count of each match as below :
STRIPCODE
MEDWAY 650
BLACKPOOL 563
HULL 352
Have a few hundred areas to match and tired of going through these manually and entering counts!

I have two tables, one being an 'Address' file and the other an 'Area' file which is a list columns ranging from 1-400 with groups of district level postcodes. For Example; column 1 will have postcodes such as BN1, BN2, BN3, BN4, BN5 etc. Each column has a separate group of postcodes.
Now, my 'Address' file also has a column within this labelled 'District' in order for me to create a straight join (between column number and District) in a query to count each group individually, but of course, do to this 400 times becomes quite tedious! (to say the least)
I would require the outcome to be as follows :
Area file - Count
1 - 469
2 - 201
3 - 0
4 - 3598
5 - 268
. - 101
. - 8936
. - 563
399 - 287
400 - 41

This is kind of a weird problem, and everything I've learned about access has been on my own through empirical experimentation so forgive my if my description doesn't make sense, or if I overlooked something really simple. (Apologies for that, I've looked over all the guides on queries and record counting I could find and got nothing on this.
I can't figure out a better way of explaining my situation so I'll do the best I can.
I need to make a query that shows the number of people that have registered for a class.
In one table I have the primary key Schedule ID which is the unique class, which is linked in one-one relationship with another field of the same name. In the second table with that field I have the field schedule ID which shows up multiple times, for each student enrolled in the course, second is the field Participant. There is the following data:
Schedule ID...Participant
1 ................ <name1>
1 ................ <name2>
1 ................ <name3>
4 ................ <name4>
4 ................ <name5>
What the result of the query should look like is this:
Schedule ID...Number of participants
1 ................ 3
4 ................ 2
But instead I get
Schedule ID...Number of participants
1 ................ 5
1 ................ 5
1 ................ 5
4 ................ 5
4 ................ 5
I have tried various variations of the Count and Dcount functions but I always wind up with that result (if it works at all)
This is the expression I am using:
Expr1: DCount("[Schedule ID]","Class Roster")
where "Class Roster" is the name of the Table that Schedule ID is located. I have tried changing it out with the name of the first table, and I have tried using participant instead of Schedule ID, but neither works. So far I've been able to use a crosstab query to get something roughly what I want but I think the assignment calls for a regular query.
Again, sorry if this doesn't make any sense, I did my best to explain it, and I couldn't find an answer anywhere. Thanks in advance for any help!
Oh, by the way, it's access '03 that I am using.
UPDATE: I have a second problem I'm trying to solve, and this one seems more confusing than the first to me. I have a table with the following fields:
Project Name, Task name, employee ID, Production Week, and Hours Worked. The first two being text and the last 3 being numerical.
I need to create a query that totals up the hours worked for each employee (one employee ID can show up under multiple projects/tasks) and returns the total hours in a particular week (week 20) of each employee that has worked over 40 hours, and only the ones that have worked over 40 hours. I can not figure out how to create a field that will sum up the hours worked for a given employee, nor can I figure out how to show only rows where the total hours record exceeds a certain amount. It seems like I would want a conditional like an IIF statement but those seem to be only for returning values, not showing/hiding.

A very elementary question - but I'd be grateful for an answer.
I have two tables (or perhaps two queries) each with a key field. If all is well, there should be complete correspondence between the two sets of records. That is, if there's a record with key 12345 in one table, there should also be a record with key 12345 in the other table.
I'm looking for the simplest way of checking whether or not this is the case, and, if it's not, detecting which records in one table are unmatched by any record in the other.

I have a database called LettersDatabase this databse holds all the letters that have been made including the path to the doc. I use SSN to ID the letters to customers on the Contacts Database.
Contacts database also uses the SSN to id the contacts
I have a form that creates new letters for customers in this form I have listbox that queries the LettersDatabase for all matching records based on the forms contact SSN to see how many letters have been made for that customer.
The problem is that my listbox only shows the first record matching that SSN but there are more records in that LettersDatabase with the same SSN that I need to have diplayed on the listbox as well.
I may be writing the query incorrectly.
Here what I have for the query on the listbox
Like[Forms]![LetterMaker]![txtSSN]
I try adding (&"*") to the end of the query but that does not help.
If anyone out there has the solution to this problem it would be greatly appreciated
Thank you

Hi
Apologies if there is a previous post that answers this - I've looked, but can't find anything that works.
I have two tables with identical structures. tblA contains a subset of the records on tblB, with identical values on all fields except ID. I need to remove from tblB all records appearing on tblA. I thought the following would work:
DELETE tblB.* from tblB
INNER JOIN tblA ON tblB.Field1 = tblA.Field1
AND tblB.Field2 = tblA.Field2
AND tblB.Field3 = tblA.Field3...
but I get "Could not delete from specified tables".
What am I doing wrong? Or is there an easier way?

Hello there,
I have tables like so (simplified):
-=Holiday=-
HolidayID
Name
Date
-=Booking=-
BookingID
HolidayID
ClientID
What I would like to do is create a query which returns a list of all the holidays with a field showing how many bookings have been created for each holiday. This almost works:
SELECT Count(1) AS CountOfBookingID, Bookings.HolidayID
FROM Bookings
GROUP BY Bookings.HolidayID;
...but it does not display holidays where there are no bookings.
Is it possible to create one which will show all holidays even if there are no bookings?
Thanks!:cool:

I have a table tblBookings.
In this table it has a bookingID, CustomerID and some other none relevant details.
The CustomerID comes from table tblCustomer. i.e a customerID must exist in the customer table to be allowed in the bookings table tblBookings
A customer can exist in tblCustomer without existing in the booking table.
I am trying to write a query that will list each and every customer ID in the tblCustomer and count the number of bookings that that customer has (even if it is zero).
I have a query that will count the bookings if they exist in the booking table and display the number of times that a customer appears in the bookings table.
SELECT tblBookings.CustomerID, Count(tblBookings.CustomerID) AS NoOfBookings
FROM tblBookings
GROUP BY tblBookings.CustomerID;
How do I create a query that will do this but list all customers even if they don't exist in the bookings table (but obviously occur in the customers table)
I am trying to create a similar query where all bookings per hotel are listed even if no bookings are made for that hotel. I am guessing the answer is the same as above.
The Ritz. Bookings 0
The Hilton. Bookings 3
The Carlton. Bookings 0
The Lowry. Bookings 2
For every hotel.
That kind of thing.
If you need more information please shout.

Hi,
I've been trying to get this for ages now - both in the design view and in sql:
I have 2 tables - one called DrawingsRegister and a related one called DrawingRevisions. Each drawing has one or more drawing revisions. I want a query that will show each drawing (just once) that has more than one revision:
SELECT tblDrawingsRegister.DrawingNum, tblDrawingsRegister.DrawingName, tblDrawingRevisions.DrawingNum
FROM tblDrawingsRegister INNER JOIN tblDrawingRevisions ON tblDrawingsRegister.DrawingNum = tblDrawingRevisions.DrawingNum
WHERE ((Count([tblDrawingRevisions]![DrawingNum])>"0"));
Thanks for your time,
RCurtin.

I have two tables, categories and items. I have a form that is linked to the categories table and a subform that is linked to the items table. The user selects a category on the main form then an item to add to the category on the subform. (all of this is functioning correctly - but you need to understand for my question.)
Both the form and the subform have a text box that displays a record from their respective table, for the example we will call this color.
What I need to do is create code that checks the color text box from the category (main form) against the text box for the item (subform) and if they are not a match I need to display a message box - from where I can then add the necessary actions.
EDIT: note this is not a query on an entire table or 2 it is just comparing the two text boxes on the form and subform

Suppose I have two tables with fields as follows:
Assigned Courses (Courses that employees should do)Employee number
Assigned Course Name
Fulfilled Course (Courses that employees have done)Employee number
Fulfilled Course
Now I need to do a query that tells me which employees haven't done. Is there anyway to do that that is not an exclude query?

I have a form that is bound to a query that returns all records matching a set criteria (namely, the field ApprovalDate is null); the idea is that the user clicks on a command button which gives information, and if the user chooses to continue (vbYes), then the field ApprovalDate has its value set as the current date, and the record is saved.
Next, I have put in DoCmd.Requery to requery the form and effectively go to the next record wanting approval - this appears to work fine, however I need to add something to the code that handles a null return from the requery - preferably a message box and then have the form close.

I have a datasheet form listing prospect information.
Each prospect is assigned a position, there can be more than one prospect with the same position.
I'm trying to get a text box to lookup the prospects position and search the remaining rows for matching positions and return the total number found.
This data does not need to be stored anywhere, just a reference value for users to look at.

Hi All,
I have a strange problem that has me beaten.
I open an Access 2003 table, sort on field "Job Number", click the Find button and enter a job number.
I expect to find 30 records, but Find only hits 8 of them.
If I over-type the Job Number (with the same numerics), Find is then able to return this record.
If I place my cursor in ANY of the 30 records and click Filter by Selection, all 30 records are included.
I thought there may be a non-printable character or a space hidden at the end of the field, but I expect both Filter and Find would return the same records.
Even more strangely, when my client zips the MDB file and emails it to me, this behaviour does not occur on my PC.
Has anyone else comes across this behaviour? If so, can you please point me in the direction that will help me find a solution.
cheers,
Mark Chimes

Where a many to many relationships is resolved with a linking table...Is it possible to create an entry in the linking table where the two linked tables have the same value e.g. create a entry in the linking table where client table has same value as a job profile table i.e. both are in insurance. Therefore want to create an entry in the middle table with foreign keys from either link automatically

How to get the following results using 1 table:
Field1 ID is an auto record ID, field2 ID is actually field1 ID assigned that record, in other words record 1 has a roommate (record 5) assigned to it, record 2 has a roommate (record 4) assigned to it
Table A
Field1 ID Field2 ID
1 5
2 4
3 6
4 2
5 1
6 8
Results records I'm looking to display for would be:
1 5
2 4
3 6
6 8
I only want to display all fields for records, but I don't want to show their matching record, so I want to display record1, but not record 5 because record 1 has record 5 as a roommate, want to display record 2 but not record 4.

Is it possible to use a command button (update) to update matching records in a form (Test)? I have a file (april.xlsx) in which the first column Cytogenetics ID (14-xxxx) is a unique identifier that matches a record in the database. The next column Result (NL-F, NL-M, F-VUS, M-VUS, A-M, A-F) and the date column next to it are what need to be updated in that record. In the database there is a field called Result that needs to be updated with
the text from column 2:
NL-F and NL-M = Normal
VUS-F and VUS-M = Variant of Unknown Sig.
A-M and A-F = Abnormal
There is also a Final TAT Date field in the database that needs to be updated with column 3 in the spreadsheet (Final TAT Date).So basically when there is a match with column 1 in april.txt to a record in the database, the Result field in the database is updated with column 2 of april.txt and the Final TAT Date field in the database is updated with column 3 of april.txt.
Cytogenetics ID Result Final TAT Date
14-0390 Normal 4/11/2014
14-0396 Variant of Unknown Sig 4/18/2014
