Forms :: Find Count Of Records That Use A Particular Foreign Key
Feb 7, 2014
I wish to be able to count how many times a primary key is being used in another table. In other words:
I have a Game table that lists a set of games by catalogue number, CatalogueNo. I need to create a way to find out how many times that key has been used in a GameCopy table. In the GameCopy table I create a number of stock items (StockNo) using the CatalogueNo from the Game table.
If I can in some way create a query that simple lists each CatalogueNo with its total number of copies that will suffice. I know it is most likely very simple but I just do not know how to implement it within Access without using VBA.
I am using Access 2010 and the web database so having a bit of an issue. I have tried google but no luck really - seems complex and confusing.
Basically I have a table which has column 1 of the unique id and column 2 is the project name.
When you click the drop down on the form, I want it to show column 2 (the project name) and when you click this, on the form I want it to find that record.
I have a Listbox that I use to find records in the Database. It has two fields, [ShootID] and [ShootDate]. It is curently sorted in the query by [ShootID] but I want the user to be able to change it to sort by [ShootDate] and then back again.
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.
I'm creating a form to count the number of employees with birthdays between 2 dates. There are 2 unbound date fields; Start_Date and End_Date. I have an Employee table with DOB field. I've been stuck on how to get the field to return the correct number of employees that fall within the 2 dates.
I have created a form which is having the above table as "control source". When data entering, if select a booking number from a Combo box, should checking how many records already having with same booking number and reflect the number of existing records in the form. If null records, it should show as "ZERO" records.
I have two fields on the main form and I need a total count of records between the value of the two and then enter the total in a bound field on the main form
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
i have a combo box in a form, where one has to select a country for example UK is chosen, then there is a button that when clicked it opens in a pop-up form and displays all the information related to UK.
so there are two tables : Country (CountryNo : primary key) linked to CountryInfo (CountryNo: foreign key) linked with a one- to -many relationship.
my problem is when you have to add new records to the form CountryInfo, how can i make the foreign key update automatically? thus when adding data to CountryInfo, the CountryNo must be the same to the CountryNo in the CountryTable..
i have build a small project using access 2003 and vba code one of the forms contains sub form the main form contain the main data about school and in sub form populate different > textboxes for details about classes my problem is how to fill these text boxes in this sub >form for different grades depending on id of main form and how can i change the values and >moveing first or next buttons these are simple picture
In a nutshell, I have a form where the 'Record Source' is a table titled 't_02_0_Assets'. I have several fields in the table that have foreign key references that utilize the Lookup Combo Box display control to allow users to select from a drop down list in the form.
The issue I am having is that I can't filter the text in the foreign key fields (only the ID's ).
My attempted solution was to create a control on the form (text box) and bind it to each of the foreign key ID's using the DLookUp function and then reference this control in the filter code.
My question is... how do I reference this DLookUp textbox in my filter VbCode?
I have attached a '.jpg' image of various aspects of the form including the filter code on the 'On Change' event.
Trying to use a form based on a table to choose a recordset of values, and pick the ID of that recordset to include in another table as a foreign key.
I am not sure how to even search for what I'm trying to do, though I've tried all the variants I can think of anyway.
The idea being that there are a set of values that are associated with each other, and generally found in conjunction with another set of data. So Table 1 contains data such as this, though this is greatly simplified from the numerics that are actually stored in these fields:
FooID Field 1 Field 2 Field 3 etc, etc... 1 x y z 2 d y z 3 x y q 4 x r P . . .
This data is then associated with the information in table 2, and rather than repeat fields 1-whatever in table 2 I want to use the FooID in table 2 to store the link to all of the subsequent field data. Normalization as I understand it in other words.
I cannot figure out how to pull the table 1 data into a datasheet form and allow someone to choose one of the lines of data, store the FooID into an unbound text box, or some other method, and then run an update query on table 2 to update a field with the FooID for the 12-72 records that are in that table.
Would this make more sense as a combo box in a single form? I've been trying to do this with a datasheet, but I think I'm too limited in appending a check box to an individual recordset this way, or at least I've not managed to get it to work so far anyway.
I chose the criteria 2 for the filter just as a test as I knew there are some records with that value in the master category field.
The problem is when ever i click the button to apply the filter it clears all the data as if it has not found any records with that value.
Is my syntax and method OK? Why its filtering everything out?
The only other thing to consider is that the field I am filtering on was set up using a lookup wizard linked to a table so the values stored are a foreign key (hence the value being 2 rather than something descriptive).
I have 7 fields in a listbox (1st is the ID, hidden) from the single table. 3 of these fields are foreign keys. How do I get them to display their related values instead of the foreign key value?
Background:I'm purpose-building my db to essentially track individually cataloged items, somewhat like a library system would. I have four main tables: tblMediaItems, tblUsers, tblTransactions, and tblLocations. Users wills be spending 90% of their time on the Details form for the particular media item record they're viewing.
I'm trying to show an item's transaction history on the main form. I added a listbox (because I liked that compact presentation style) and got the desired fields to show up from tblTransactions. I figured out how to accomplish this for a single column combo box with the wizard, but so far I don't see how I would do this with multiple fields in a listbox.
I'm developing a simple sporting records db. I have a 'Competitor' table listing competitors as follows: CompetitorPK, Name, Division, Club. I have a 'Contest' table listing contests as follows: ContestPK, Competitor1_FK, Competitor2_FK, Winner_FK, Score etc. My question is have I modelled tables correctly i.e. CompetitorPK will appear in three columns of Contest table. How do I define this relationship? What alternative is there to what I have done.I intend to use forms to populate both tables (independantly obviously).
I have created a booking system for a set of resources for schools. Most schools have a membership which entitles them to 2 free sets. I have a booking form with a membership subform (membership table), and a booking details subform (kitloan table).
Once a school is selected on the main form, the membership subform shows the most recent record for that school based on schoolID.I want to display the number of sets they have already had within their membership period (can start at any time of the year, and lasts for 1 year) on the membership subform, so we know how many free ones they have left.
I therefore need to count the number of KitBkID (ID of the booking) in the Kitloan table where SchoolID = the SchoolID displayed on the membership subform, and the DateOut (booking date on kitloan table) is between the DateJoined and DateRenewal displayed on the membership subform (from membership table).
I can do this with a query which works when run and provided with the parameters SchoolID, DateJoined, and DateRenewal.
SELECT Count(Kitloan.KitBkID) AS CountOfKitBkID, Kitloan.SchoolID, Kitloan.DateOut FROM Kitloan INNER JOIN Membership ON Kitloan.SchoolID = Membership.SCHOOLID GROUP BY Kitloan.SchoolID, Kitloan.DateOut HAVING (((Kitloan.SchoolID)=[Me].[SCHOOLID]) AND ((Kitloan.DateOut) Between [Me].[DateJoined] And [Me].[DateRenewal]));
What I can't do is get it to run on the form and take those values from the form.From the searching I've done, I'm thinking a DCount should be the way to go, but I cannot get the criteria right. I created a query (KitloanCountQry) so that criteria could come from both the kitloan and membership tables.
SELECT Kitloan.KitBkID, Kitloan.SchoolID, Membership.DateJoined, Membership.SCHOOLID, Kitloan.DateOut FROM Kitloan INNER JOIN Membership ON Kitloan.SchoolID = Membership.SCHOOLID;
I have put the DCount as the control source for a textbox on the Membership subform (but have tried it in VBA too): =DCount("KitBkID","KitloanCountQry") This works but obviously gives me the total for all bookings.
[code]....
Although I have to admit to getting lost in the syntax. This produces #Error.
Hi I'm have created a video database with a genre field. Is there a way that when i click a button a list is displayed of all the records which are the same genre? Thanks Aden
How would one go about comparing 2 tables and finding those records that are not common to both tables? For instance, I have a table that I suspect some records have been accidently deleted by the user. I would like to compare that table to an older version of the table, and list only those records that exist only in the older version of the table. Thanks.
Iv'e looked through several date functions but cant figure out which one to use or how. I want to produce all records for a period of 1 year, for 1 year ago. i.e if I run the query during any month of the 'current year' (obvously) if its after August it will show me the previous year of August to following July. My Start date is always August 1st of any year through to the following July 31st. It is relatively straight forward (I think)if it's from January to December because year part is the same but this becomes more complicated when you cover two different Year parts. I dont want to have to use a parameter Query of 'start date' and 'end date' I want to be able to run the query based on the system date now(). Any help would be appreciated thanks.
Hi, I have a table contains 5 fields are shown as below, how I can write a query to find out the duplicate of the records? I have created a couple of queries by using Find Duplicates Query Wizard to do it. But the results are not accurate enough.
Field 1: ID Field 2: Trading Name Field 3: Location No Field 4: Location Street Field 5: Location Suburb
IDTrading Name Location NoLocation StreetLocation Suburb 41350Arabica Café Grey St 263Arabica Cafe` 1GREY STREET 41294Arashi Japanese Resturant41Courtenay PL 150Arashi Kushi Yaki Bar41COURTENARY PLACE
From the data sample, I could like to find out the duplicated records. One of the queries is shown as below. But they cannot pick up these records. Any better way to find the duplicated records? Please help.
SELECT DISTINCTROW [C&B-will].[trading name], [C&B-will].[location street], [C&B-will].Field1, [C&B-will].[location no] FROM [C&B-will] WHERE ((([C&B-will].[trading name]) In (SELECT [trading name] FROM [C&B-will] As Tmp GROUP BY [trading name],[location street] HAVING Count(*)>1 And [location street] = [C&B-will].[location street]))) ORDER BY [C&B-will].[trading name], [C&B-will].[location street];
