Queries :: One To Many Relationship Between Tables Containing Membership Details
Nov 25, 2014
I have a table with name, club members details ID etc. This is linked by a 1 to many link (ID) to a table containing details of membership subscription payments. One entry/row per membership period. This second table has DatePaid, Paid (Yes/No), Period. Period contains 2013-14, 2014-15 etc.
I can do a query for those that have Paid (Yes) but when I try one for those that have not Paid (No) or <>Yes I get no result. I only enter members when they have paid. I need a query to display those who have not paid for the 2014-15 period.
I can do it a long winded way copying 2 lists into Excel. One all members. One those who have paid. Then remove duplicates and those paid in 2013-14 leaves those not paid in 2014-15.
I've made a membership database for an imaginary leisure centre as part of my A Level coursework - only after more or less finishing my project, I've realised that I haven't provided a way for the end users to calculate fees for members.
I suppose the calculation I would have to do is multiply the Length of Membership (days) field on the Membership Opportunities by Cost per Month on the MembershipTypes table.
These are the relevant tables and I've also attached my database (the password is "password" for any of the users) ...
I have a very simple query to determine the gender ratio of an associations membership. My SQL code neatly calculates the number of females, viz
SELECT [Mail List].[GENDER], Count([Mail List].[GENDER]) AS TOTAL FROM [Mail List] WHERE ((([Mail List].[GENDER])="F")) GROUP BY [Mail List].GENDER;
However, I wish to present this result as a percentage of total membership.
My main Table has a column titled [Member Name] so my requirement is to produce a calculation of the form "Females"/"Member Name Total" all multipliied by 100.
Hello can anyone help me with my prob. I am trying to call up records from two different tables to display on the same page but haven't been able to get it to work. I have a table called members and another called Messages. The page that the info is called up from is called viewtopic. I can get the topics to display properly but without the members stats with this query:-
'sqlString = "SELECT * FROM Messages WHERE TopicID=" & topicID
but I need the member stats to be displayed too so I developed this query which doesn't work at all:
sqlString = "Select Messages.Topic, Messages.TopicID, Messages.BSection, Messages.MesDate,Messages.Message, "&_ "Messages.Edited_On, Messages.Message_ID, Messages.Member_ID, Messages.Username" sqlString = sqlString & " FROM Members INNER JOIN Messages " sqlString = sqlString & "ON Members.Members_ID=Messages.Members_ID" sqlString = sqlString & " WHERE Messages.TopicID=" & topicID sqlString = sqlString & " ORDER BY Messages.MesDate "
This comes up with No value given for one or more required parameters which I'm guessing is for the members_ID but I'm not sure. There is a one(members) to many(messages) relationship on the two tables. Can anyone tell me where I have gone wrong in the query?
I've inherited a data base which has the address details of our members spread across multi fields i.e. Add 1, Add2, Add 3, Post town, Post code etc.
Not all the fields contain information which means when I do a mail merge for address labels there are blank lines.
I would like to either be able to create a single field in the table (like a memo field for example) which contains all the address detail, or create a mail merge without blank lines.
I have been managing a database system for a homeless shelter in my volunteer role. There is a certain feature that would improve accuracy of the inputted records, as well as freeing up time for staff. That is - auto filling a user's Gender and Nationality when inputting a record for the drop-in centre.
Currently, when a forename and surname is inputted in the "DropIn_Input" form, it is checked against the stored 'service users' table and checks for the name combination. If the name combination is not present then the forename and surname fields change to 'New'.
What I would like is to keep this, but if the service user name is stored in the 'Service User's table then I would like their Gender and Nationality to be automatically filled into the fields on the 'DropIn_Input' from the relevant information in the 'Service Users' table.
I have written a simple query for address label printing purposes, but I do not want to print labels to identical postal addresses.This sounds such a simple requirement but my efforts to write a simple 'criteria' in the Address1 Field have been unsuccessful.
I am trying to retrieve data for a particular record.
When Project field matches a certain project number I want it to pick the record with the latest date in the date field field to select certain data fields(Owner & Rating) from that record.
Below is my attempt. However the problem is that displays all records with that project number and not just the record with the latest date.
Code: SELECT [Combined PRB Roadmap].ProjectNumber, Max([Combined PRB Roadmap].DateField) AS MaxOfFDateField, [Combined PRB Roadmap].Owner, [Combined PRB Roadmap].Rating FROM [Combined PRB Roadmap] GROUP BY [Combined PRB Roadmap].ProjectNumber, [Combined PRB Roadmap].Owner, [Combined PRB Roadmap].Rating HAVING ((([Combined PRB Roadmap].ProjectNumber)="NR-4237"));
Is it possible to once you have run a query be able to somehow double click on the results in order to either go to original record or see more details? Similar to "show details" in excel?
I have made some queries that are working well however they are specific in nature and once found display a list of results. I have left a field that uniquely identify them and are after a quick way to view the details of the results from the query rather than take the ID# and manually search the original table.
I have two tables of data, each relating to three business branches (branches A, B and C).
Table 1 shows the expenditure of each branch (by fuel, premises and wages).
Table 2 shows a number of units for each branch (mileage, floorspace and sales).
What I would like to do is calculate unit costs, based on the expenditure in Table 1, divided by a relevant unit in Table 2. The catch is that I want to have a third table which allows the user to specify which expenditure (from Table 1) is combined with which unit (from Table 2) to generate the calculated unit costs. I've been able to do this in Excel, and have attached an example. I've also attached an incomplete Access version with the first two tables. Given the complexity of my actual data, I feel this could be better handled in Access than Excel.
Table 1: contains staff names and contact numbers Table 2: contains training above staff have been on or need to go on Table 3: contains pc and printer asset numbers of above staff
I used a form and entered some new members of staff in table 1. They got their auto numbers etc but when I open table 2 and table 3 those new members are not showing up in those tables. I have checked the relationship status between the 3 tables and the staffID from Table 1 is associated to table 2 and to table 3.
What's stopping the new entries from showing up in tables 2 and 3 ?
I'll first of all explain the purpose of the query. I've built a database to record the admission details of patients admitted to hospital. Amongst other things, the database captures date/time of admission and date/time of discharge.
The query I am building needs to show patients with multiple admissions, and in particular, the number of days that have elapsed since they were last discharged. Within my query is the following subquery that I had written to show this aspect of it:
(SELECT TOP 1 Dupe.[Discharge Date] FROM [Inpatient Database] AS Dupe WHERE Dupe.[CHI Number] = [Inpatient Database].[CHI Number] AND Dupe.[Discharge Date] <= [Inpatient Database].[Admission Date]) AS [Previous Discharge],
Note: "CHI Number" is a unique reference number assigned to every patient.
I then display in a column [Admission Date] - [Previous Discharge].
This works fine where a patient only has one previous admission. However, where a patient has multiple admission, the subquery always returns that patient's first discharge date instead of their most recent discharge date (because I have used the "TOP 1" predicate). It seems that it should be straightforward enough, however I can't seem to work around it. Anything I try results in errors, and so I keep defaulting back to my "TOP 1" solution.
i.e. What I want it to show is: Name.......Admission Date...Discharge Date.... Previous Discharge... Days Between Admissions Joe Bloggs ..01/01/2014 .......10/01/2014 Joe Bloggs ..15/01/2014 .......20/01/2014 .......10/01/2014 ..............5 Joe Bloggs ..27/01/2014 .......01/02/2014 ........20/01/2014 .............7
However, what it actually shows is: Name ......Admission Date ...Discharge Date ...Previous Discharge ...Days Between Admissions Joe Bloggs ..01/01/2014 ......10/01/2014 Joe Bloggs ..15/01/2014 ......20/01/2014 ........10/01/2014 .............5 Joe Bloggs ..27/01/2014 ......01/02/2014 ........10/01/2014 .............17
Hi I have been asked by my tennis club if I could set up a small Access database to help with membership registration and fee collection. Ideally, it would go on to record coaching sessions for juniors, etc but that can come later. Does anybody have a template that I could use as a basis for my development? Regards Noel
Ok the database that i have contain all the details about customers including thier joining date. I want to make a query that will produce relevant information for use on a membership renewal letter, It should show only members due for renewal on 1st of may (there are 3 renewal dates per year. 1st jan , 1st may and 1st sept. I need to assume that the next renewal month of membership for those joining between those months will be the next renewal date. Example if you join in June your renewal date would be 1st september)
Could you please explain how i could do this in easy to understand language as i am no expert with access.
Hiya... I have a form where new records can be added to a table. I was wandering if it was possible to automatically add 1 to a textbox that is bound to a membership id field within that table.
So when the form loads, the txtmembershipID has the next number displayed.
This is my code for the load event. DoCmd.GoToRecord , , acNewRec
Hi, Im putting together a membership data base. the data base has an already existing client base which all have membership numbers in the form of first letter of there sir name, last to numbers of the year and a 4 digit number. So for example Joe Bloggs membership number would be B06001 his sister Betty Bloggs would be B06002 and the guy next door John Doh would be D06001.
What I would like to do it automate this system so everytime I make a new record when I input the sir name into the 'lastname' field on the form it checks the last Membership number and makes a new one. I wouild also like it to change the 06 to 07 when the year changes.
Ive done searches for things like this with Dmax etc but i really could use help with the code as I have no idea how to code this type of thing?
Any ideas on this oue would be great! Cheers Phill
I have to change a group membership of one user in an multi user access database. As I see its no possibility to change it in the backend (in X.ldb file) nor in frontend.
I've only just started using Access 2007 at my new job. I've been asked to create a database that will show appointments for all 10 of the employees. I have created a table for the main schedule (where ill put all the data) then one for each of the employees. I've managed to link the tables no problem but it wont let me create and updating relationship. It keeps saying "no unique index found for the referenced field of the primary table". How do I fix this?
I want it to automatically update the date, time, location, customer name and description, if its changed on the main schedule for a certain appointment on the corresponding employees schedule.
I created two tables, but i don't know what kind of relationship i should create.
In the first table, i would like to put all different tests (medical tests, such as EMG test, and so on), in the second table, i want to add the settingup for each test, say, recording site, stimulating site et.al, then i want to use one form to populate data into these two tables, what should i do?
I am trying to define a relationship between tables. However, the unique nature of my data doesn't seem to be allowing typical relationships. I am not sure if I need to somehow create a relationship (junction table?) or just keep things as they are. Do I need a Foreign Key? FYI, I am only querying the data - no updates.
I have two tables that I am able to join by using a field in Table1 tied to a portion of a field in Table2. No other columns in either table can reliably relate the two tables. For example:
Table1.ColA has a 5 character string. Table2.ColA has a 10 character string.
I need to match Table1.ColA to Table2.ColA where the first five characters in Table2.ColA match Table1.ColA.
This match, produces 1 to Many results (for every Table1.ColA string, there are 1 to many Table2.ColA records that match.
IMPORTANT FACTORS: - Table1 contains data at a SYSTEM level. - Table2 contains the parts that make up the "SYSTEM" in Table1 - The PARTS in Table2 can be in 1 to many SYSTEMS from Table1 - Table1.ColA is not unique by itself (it's part of a composite PK in Table1). - Table2.ColA is not unique by itself (it's part of a composite PK in Table2).
I have a db with two table. Table1 Trade has the following among other fields: RefNo (autoNo) PK, TradeDate, HostName, Methodology, etc.
Table2 Market has the following among other fields: MarketDate as Date ( ), USD/EUR_Rate, USD/CHF_Rate, USD/BRL_Rate, etc.
I need to link both tables so that the TradeDate correspondes to the MarketDate. what is that say on TradeDate if it is on 15/01/06 I can see what the Market values for the MarketDate corresponding to that TradeDate.
I tried to link MarketDate as PK on Market table2 to TradeDate on Trade Table1. It seems to work but it does not seem right as sometimes I get errors in entering data, etc on the Market table2. The MarketDate is unique meaning only one data of values for a given date, they can be modified but not duplicated.
Can anyone help, on the best solution for the links to work?
I feel confused about something and I have the need for assistance because solving this small thing would make my life easier. I very much appreciate you taking the time to read this.
I want to normalize my database as much as possible.
I will make a make a form for Breakpoint containing two comboboxes. The top combobox will contain all Modules and I want the second combobox to contain only the Functions that are related to the selected Module from the first combobox.
I know this can be programmed, that's how I do it now: in the onChange-event of the first combobox, I load the content of the second combobox.
However: what I would like to know specifically 3 things: --> what is a common way to solve this? --> Is there a way to solve this using just table-relationships? (drop 2 cbo's on the form and with correct relationships access populates the second and/or the first automatically) --> What are the correct table relationships for this and therefore what missing ID's (used for relationships) have to be filled in in the above 3 tables?
Tables: I have 2 tables, there are same fields: Name, Date, and Invoice #
I make a relationship between 2 tables, connect Name, Date, and Invoice # And click "Enforce Referential Integrity", "Cascade Update Related Fields", and "Cascade Delete Related Records".
One-to-One.
After that, I go table 1, create a record, then close it, then open table 2, the record I created in the table 1 is NOT over there. Does the relationship create record? It only update and delete. What about Add ? Please let me know about it. Thanks.
