Self-join Not 100% Working - Please Help
Feb 11, 2006
I'm trying to create a database of Publications (instruction manuals) where one publication is a modification to a parent modification. I'm storing all 'publications' in one table for better maintenance. This means that I have to use a Self-Join if I want to make one the parent, and one the child. Fundamentally this is no different than the Employee/Supervisor example I've found in many places:
http://www.databasedev.co.uk/self-join_query.html
I created a query with two copies of the same table with the 2nd one renamed for easier viewing. The query final comes up, but when I choose "ParentPub", it doesn't give me a drop down showing the other pubs so that I can choose one to be the parent.
What did I do wrong? I should be able to open up the table 'tblPubs', and get a drop down menu showing me all the pubs I can assign as a parent.
Thank you for your help,
Enrique

I have a query where I'm selecting fields from two tables - Students and Attendance. I have selected option 2 in my Join Properties, i.e "Include ALL records from Students and only those from Attendance where the joined fields are equal". The tables are joined by StudentID. Either I'm misinterpreting what the join is supposed to be doing or it's not working.
I need to see every record in Students regardless of whether or not they have a record in Attendance. I need to calculate absences and tardies. If there's a matching record in Attendance, I subtract the date absent from the total days. If there's no matching record in Attendance, I still need to calculate total days and show it. As it is now, if there's no matching record in Attendance, it doesn't do anything. How can I get it to do what the join says, "Show ALL records in Students as well as those that match in Attendance?
Thanks

I've been toiling with the issue of WHERE clauses on the "Right" side of Left Joins. I'm aware that you need to use JOIN ON......AND.... rather than JOIN ON....WHERE.... if the WHERE relates to the Right Hand table.
I've even got an example in my DB where the above works, but now am struggling to use the same theory for other tables. Therefore, I went and created two Mickey Mouse tables to test the logic but am getting an error.
I have
Table 1 with one field called Field 1 - values A, B, C
Table 2 as follows
Field 1.....Field 2.......Field 3
A.............100
C.............200..........XXX
I hoped to have a query that finds all records on Table 1 and records on Table 2 where Field 1 matches on the two tables and Field3 = XXX
My SQL is
SELECT Table1.Field1, Table2.Field1, Table2.Field2, Table2.Field3
FROM Table1 INNER JOIN Table2 ON Table1.Field1 = Table2.Field1
AND Table2.Field3="XXX";
but I get Join Expression not supported
What am I doing wrong?
Thanks

And then called this join as a symbol or variable, and then have it use to select the items from these joined tables, can this be done in Access? Here is an example of a code that I created, but it has an error message saying the FROM syntax is incorrect.
Code:
SELECT firstJOIN.trainID, firstJOIN.trainName, firstJOIN.stationID, firstJOIN.stationName, firstJOIN.distance_miles, firstJOIN.time_mins
FROM (trains INNER JOIN ((station INNER JOIN lineStation ON station.stationID = lineStation.stationID)
INNER JOIN bookingLeg ON bookingLeg.startID = station.stationID or bookingLeg.endID = station.stationID )
ON trains.trainID = bookingLeg.tid) as firstJOIN
Can Access do something similar to this, in the FROM statement I joined 4 tables, because each unique fields are in each table and I have to joined them to get those fields. I called this join firstJOIN and in the SELECT statement, I list those columns in the table by calling it firstJOIN.trainID. Can Access do something like this, but syntax it differently?

I am trying to do an inner join with a left join. The only problem is, I want to inner join the table that is being joined. This is how I thought it would work below, but it doesn't work.
SELECT * FROM ((Submissions LEFT JOIN Candidates ON Submissions.`Candidate Code` = Candidates.`Candidate Code`) INNER JOIN `Type Candidate Status` ON Candidate.Status = `Type Candidate Status`.`Status ID`)
WHERE Submissions.Status <> 7 ORDER BY `School Interest` DESC;
I want to get the Candidate.Status to inner join with the `Type Candidate Status`.`Status ID`.
If you can help, thanks in advance.

I have a program that runs under access 2007 that I use at my work. We will soon be updating to MS office 2010 and the program will not work now because a calender file .ocx was removed from access 2010. Is there a way to get the 2007 .ocx file to work in access 2010?The program I am using is a relatively simple stand-alone and unsupported app that we use to request patient arrival and departure from various radiology tests inside a hospital. No reports are made from the app other than the number of patient transports for the day.
The app is placed on a common drive accessed from any pc in the hospital. No special permissions are required. But our app does use the calendar, time and date functions in access 2007. When I tried the app on a pc with access 2010, it basically says it (access) cannot open the app because a .ocx file is not present.Is there a way to make the access 2010 calendar file work in access 2007?

I have an Access 2010 database with two tables and two forms. The tables are Organizations and People. Similarly, the forms are Organizations Entry Form and PeopleEntryForm. The People are linked to the Organizations table. Several people can be linked to the same organization.On my Organizations EntryForm, I created a command button to duplicate a record using the wizard. It works fine.
I did exactly the same thing on the PeopleEntryForm, but instead of copying the record, it creates a new blank record. I don't get any error messages. Is my problem due to the fact that the People table is linked to the Organizations table?

I having a little trouble with a query I was hoping someone could help me with. Basically I have the following SQL statement
[code].....
I would like to show all records for the tblCService.CService field however it won't let me change the join to a RIGHT JOIN. I get an "ambigious outer joins" error message. As far as schema tblEList is the main table and the tblCService is a lookup table. Any ideas?

hello everyone,Please can someone tell me if it is possible to create a Join on two tables where the value from 1 field is contained within a field from the other table.eg.table1.field = "xyz"table2.field = "the xyz super thingy"This is the SQL it gave me orrigionally but this is an "= to" join which is not what i want. I tried replacing the = with a LIKE but am still getting the same results.SELECT table1.*, table2.*FROM table1 INNER JOIN table2 ON table1.modelno = table2.name;SELECT table1.*, table2.*FROM table1 INNER JOIN table2 ON table1.modelno LIKE table2.name;

I have a database with PCs and installed hardware. An external program scans all PCs, the result of the scan can be saved as Access file.
Now I need a query to select from each PC the installed hardware (Monitor, Printer...) but only with the latest date. I have written a query MaxDatum to select the the lastest date. Here's my query code:
SELECT [Table1.needed fields], [Table2.neede fields]...
FROM (((Table1 INNER JOIN (Table2 INNER JOIN qryMaxDatum ON (Table2.Field1 = qryMaxDatum.Field1) AND (Table2.Field2 = qryMaxDatum.MDate)) ON Telle1.Field1 = Telle2.Field1)
INNER JOIN Table3 ON Table2.Field2 = Table3.Field2)
INNER JOIN Table4 ON Table2.Field2 = Table4.Field2)
INNER JOIN Table5 ON Table2.Field2 = Table5.Field2
ORDER BY Table1.Field1;
My problem: this query mulitply the number of data records so that I have 80 data records with exactly the same content per PC. How do I neesd to change the query to get only one data record per PC?

How do I only bring back the top 3 from the join in this query?
There will be multiple records in the InvoiceNotes table and many different invoices.
select invoice_no, inv_date, totamnt, projman, invoicenotes.note, invoicenotes.notedate
from invoices
left join invoicenotes on invoicenotes.invno = invoices.invoice_no
The InvoiceNotes tbale has an ID column so I can order by MAX(ID) DESC and then get top if needed

Not sure if I'm going in the right direction, but am stumped at this one!
I have a few tables:
tblDailyTripLog
ID; TripDate; Departing; ETD; Destination; Depot; Driver
tblDepots
ID; Name
tblDrivers
ID; Name
Now, in tblDailyTripLog.driver, the tblDriverID is stored. Same goes for Destination, Depot & Depart, the tblDepots.ID gets stored which can or will differ....
Now, when do a query, how would I show 3 different joins to the same table (ie. tblDepots) to get the name, instead of the ID for Departing, depot & Destination?
I've tried doing a Left Join and then another LEft Join, but its not working....

How do I join two tables. I have a table and a lookup table. My table has products on there that are listed as custom or basic. I have a look up table that has an ID for basic and Custom. In my table, i want it to read what the id is for each product instead of it reading "basic" or custom. Someone said that I need to join the two tables and do an update query, but I don't understand how to.

That is the question:
Whether 'tis nobler in the mind to suffer
with VBA Programming and the outrageous errors,
Or to take up arms against a sea of Access troubles.
Sorry I was in the mood for Shakespeare.
A quick summary first:
In the attached file I have my Relationships. One main table, Workorders with various one-to-many relationships back to their respective tables. If you look at the attachment and see a field with 'wrk' that's my foreign key.
What I'm trying to do is this:
Where-ever there is a 'wrk' field I want to add in all the fields (minus the ID Primary Key) into the main Workorders Form.
Then on the form itself I should just be able to enter in the data that is required for the fields.
So here's what I'm thinking for the coding is to Join the various tables to thlet me know if I'm on track or not. I'll start with a small one, because if I can get that right, the rest should be simple.
SELECT Model.ComputerID, Make.ComputerID
FROM Computer
INNER JOIN wrkComputerID ON Model.ComputerID = Make.ComputerID;

I need to write a query which retrieves all the records from first table and those matching from second table and also satisfies a criteria.
I had
Table 1
F1
F2
F3
Table 2
F4
F5
F6
F7
I had to get all the records from Table1 and also those matching with Table2
So i did left join and getting all the records.
And I also need to check whether F3 in Table1 is in between F6 and F7 of Table2.
So I wrote query like this
SELECT Table1.F1, Table1.F2, Table2.F5
FROM Table1 LEFT JOIN Table2 ON (Table1.F1 = Table2.F4) WHERE Table1.F3 BETWEEN Table2.F6 AND Table2.F7;
I am getting only those records which are matching where condition.
I need to get all the records including which match the criteria and also those which don't match.
Please any suggestions?
Thanks

Hello All: I am trying to do a query to join two tables. One is our table of products we sell by a certain manfaucturer. We sell about half the items that Manufacturer makes. The other table is everything that manufacturer makes.
I am updating prices. I am pulling out Product ID from both tables and our price from our table and new prices from the manufactures table. The Query I did only shows matching fields. I want to remove old items from out table, and possibly add new items from the Manufacturer.
I hope this isnt too confusing. Would this be a many-to-many join?
Thanks

Hi
I am trying to use left join on the following tables.
Employees
----------
EMPLOYEE_ID
FIRST_NAME
LAST_NAME
and
Weekly_Timesheets
-------------------
EMPLOYEE_ID
WEEK_NO
YEAR_NO
TOTAL_HOURS_WORKED
All I want is to pull all the employees with their corresponding total worked hours. There are cases when some employees forget to fill their time sheets in a week and might not have entries in weekly_timesheets table. Since I want all the employees irrespective of whether they have a record in weekly_timesheets or not I am using left join.
The left join I am using is as follows:
SELECT EMPLOYEES.EMPLOYEE_ID,
WEEKLY_TIMESHEETS.TOTAL_HOURS_WORKED
FROM EMPLOYEES
LEFT JOIN WEEKLY_TIMESHEETS
ON WEEKLY_TIMESHEETS.EMPLOYEE_ID = EMPLOYEES.EMPLOYEE_ID
AND WEEKLY_TIMESHEETS.WEEK_NO = 46;
The moment I am trying to execute this statement Access is crashing. I couldn't figure out what am I doing wrong.
Kind Regards
