Full Outer Join For Dummies
Mar 21, 2007
I'm the dummy in question. I'm new to Access and have a fairly simple database that I'm using to find potential customers. I am targeting them by two criteria using two different queries (both queries are looking at different fields of the same table). I want to create a combined query that pulls ALL of the results from both of my target queries. Searching around this forum I see that I need to create an Outer Join which Access doesn't exactly do. I also see that there are ways to simulate this, but I can't seem to figure out those ways. If someone could please explain this to me in a very simple way, I would be very grateful. Thank you.

I would like to create a full outer join in Access2010 between two tables with many to many relationship.
So I have tblServer and tblApplication and there is also the ServerID-ApplicationID table that connects these tables.
I found online many examples but all of them where for two tables with one-to-many relationship.

I am fairly new to Acces 2010.I have two seperate tables hat I need to use to compare data. As you can see table A and table B have some of the same item numbers but they also have different item numbers that are not other table. Also some of the item numbers are duplicated in each table but that is okay because the cost of the item is different. Both tables contain item numbers for the products. I want all of Table A item numbers including the item numbers that are in table B. But I also want Table B item numbers except for the item numbers that are also in Table A. In the real raw data file some of the item number fields are blank but the other fields have values. How should I query these tables so that I achieve the correct results?
Table A
Item Num Costof Item Supplier Sales Tax Purchase Month
1234 $1.00 Walmart $2.00 Dec 2013
2222 $4.00 Walmart $1.00 Dec 2013
2222 $2.00 Walmart $1.00 Dec 2013
1276 $3.00 Sams club $1.50 Dec 2013
7898 $5.00 Texaco $5.00 Dec 2013
4567 $3.50 Food Lion $1.00 Dec 2013

Okay i have 3 tables
I would like to join them all by a field called twp, but the problem is in some tables the field twp might contain more or less rows than table2 and table3 or vice versa.
Is there a way to include all the rows from all tables in a query.
Suppose if table2 has a column which table1 doesnt have, then it will just show table1 column as blank etc..
Iv tried just doing an outer join on all the tables but for some reason access doesnt allow it.
Thanks in advance

Hey Folks,
I'm trying to write a query that will get all the records from one table, and only certain records from others. (Access2000) I'm getting a "join expression not supported" error however, so my question is two fold.
1. Does Access2000 support an inner and outer join the in same query?
2. Does my query below just have a syntax error thats causing the problem?
Here is the SQL, i've posted a rough table schema below too. (please note i'm using ColdFusion to query the database, so the #tstiid# is a variable passed to the query)
SELECT ((iss.iid, pg.pgid, pg.pg_name
FROM issues iss
LEFT JOIN issuespages ip ON ip.iid = iss.iid)
RIGHT JOIN pages pg ON pg.pgid = ip.pgid
WHERE iss.iid = #tstiid#
Database layout:
Table 1, named: issues
iid | issuename | a ton of other fields
------------------------
1 | April 2006 |
2 | May 2006 |
table 2: pages
pgid | pagename | pagecontent | etc
-------------------------------------
1 | Contact us | To contact us, use the following...
2 | News | Upcoming news...
table 3: issuespages
ipid | iid | pgid
--------------------------
1 | 1 | 1
2 | 1 | 2
Thanks in advance for anyones time!

Hi All
I have been running a query to find out the name and addresses of some of our customers but some data keeps coming in to the results that i dont want to see.
The data is in the Name column so I have built a second table and put the names of the items i do not wish to see in the second table using a left outer join and selecting null or not null. This works great if i know all the combinations of the name such as smith i.e d smith david smith, sam smith dd smith etc.
I would like to enter Smith into the table and have my query return everything except with the word smith in.
I can code this into the query with not like *smith* but that means everytime i want to go into it i would have to enter the query not the front end
Anyone any ideas?
Thanks

Hello All,
Beginner level question!
I am working on a schema that might need outer joins for some of the queries and thereby reports I will need to produce. So, I wanted to get an idea from the pros about the following strategy:
How about leaving all the joins in the Relationships to begin with as Inner Join and change them to Outer Join as required (for a given Query. I believe this is possible)? What are the pros and cons of this approach.
Thank you

Hi!
Thanks for all help so far, this forum is great ;)
I have 3 tables: Order, Product and Names.
I want to list All orders, no matter if they hold a key to a product or not, and no matter if this product has been given a name (in the table name) or not.
To make it even more complicated, the customer can give upp to 16 namesuggestions, they are all numbered from 1-16. But If they are given a namesuggestion, i only want to present the first one (nr 1).
Relations: 1 order -> 0 or 1 product.
1 order -> 0 or up to 16 names, of which i only want to display nr 1.
Any suggestions?
I am thinking of preparing the data in a temporary table, but would be glad if i did not need to do so....

I have a table and a query. The first 4 fields of the table correspond to that of the query. The query does not have any other fields, but the table has 26 more fields. Is it possible to use SQL OUTER JOIN or UNION or whatever to append the data of the query to the table or do I have to go with recordsets of VBA?

ISNULL(B.Delivered_Date, B.Delivery_Date) AS Start_Date, ISNULL(C.Delivered_Date, C.Delivery_Date) AS End_Date
FROM dbo.PROJECT A LEFT OUTER JOIN
dbo.PROJDATE B ON A.Project_ID = B.Project_ID AND B.Date_Type = "Start Date" LEFT OUTER JOIN
dbo.PROJDATE C ON A.Project_ID = C.Project_ID AND C.Date_Type = "End Date"
Can anybody help me out the error with this. I get an error : at dbo.PROJDATE B ON A.Project_ID = B.Project_ID AND B.Date_Type = "Start Date" .
Do I need to use any parantheris or change anthing.

I have 2 tables (tblItemsQB and tblItemInfo) that have a 1 to 1 relationship linked by the "PartNumber" field. The tblItemsQB table contains a description field and 2 price fields (this table is downloaded from Quickbooks). The tblItemInfo table contains additional fields with information on the part that isn't contained in Quickbooks, like OrderType, Phase, SubSystem.
I import the items from QB into tblItemsQB and then do an outer join with tblItemInfo to link all the information for the part. If I have created a new part in Quickbooks, when I do the outer join (I include all records from tblItemsQB) I can see the new part but since the part number doesn't exist yet in tblItemInfo, I can't add the information to the fields in that table.
What is the easiest way to create the new PartNumbers (those that exist in tblItemsQb but not in tblItemInfo) in the tblItemInfo table so I can add the other information to it?
thanks

My goal is to create a form that allows me easily edit what State each City is assigned to, and edit what Country each State is assigned to. I have 3 tables:
tbCities
CityID (Primary Key)
StateID (Foreign Key from tbStates)
City
tbStates
StateID (Primary Key)
CountryID (Foreign Key from tbCountries)
State
tbCountries
CountryID (Primary Key)
Country
For right now, I want to focus on just States and Cities... so I also have this query:
quCity_to_State
Field: City
Table: tbCities
Field: State
Table: tbStates
The join type for the relationship between tbCities and tbStates is: Include ALL records from 'tbCities' and only those records from 'tbStates' where the joined fields are equal. That way I can see all the cities and the state they are assigned to.
However, when I view the query in datasheet view and try to type anything into the State field of this query, I keep getting this error: "Cannot enter value into blank field on 'one' side of outer join". I figured the source of the form should be this query instead of the tables directly, but if I can't input data into the query then I wont be able to input data into the form.
What am I doing wrong?

Now that i have read this again, i think it could be summed up into one question...if i have a form based off a query with an outer join that has various duplicate records, is there a way to use the recordset in an if statement that says something like if this recordID = that recordID then dont show one of them...hence not showing the duplicate field data in the form.If you want a more specific description of the problem, read on, otherwise don't read on.Hi All,So I hope I can explain this ok....here goes....I have a search using dynamic queries: I have a form where the user can put in various information he wants to search to find a record. In this case it is searching for Hotels. So the user can search a country to see all of the hotels in that country. Also, the user can search an interest like Beach or Nature to see those hotels that apply. Obviously each hotel may have more than one interest so I have a 1-many relationship with a table called Hotels_Interests.The kicker, and you can likely already see why, is that the user does not have to fill out every search field. He may search Country&Interest, or just one or the other, or leave everything blank to see all hotels in the database. The results are simply ordered by HotelID or something like that in a form that is based off the dynamic query. The dynamic query is of course just based off the query i explained, but with criteria added in.The problem is with the query that i am basing this search off of. Right now it has the main Hotels table as well as the 1-Many table Hotels_Interests and even another that is 1-Many Hotels_HotelTypes (say All Inclusive, Resort, etc.). So this query has various 1-Many tables as well as the main Hotels. Now, if i fill in all of those fields in the search form, there will obviously not be any duplicates returned, which is super. But if i leave Hotel_HotelTypes search field blank, i will be returned with the same hotel twice or more times, which is my problem, because i want nice search results.I have heard of people using Union queries to get rid of duplicates but this obviously does not solve my problem as i do not want to just get rid of these entries. What i think i want is some VBA method or whatever of showing in my search results each HotelID that meets the search criteria only one time.Right now i have it working with If statements that say if the user has left a specific search criteria blank then base the search off a different query. This is obviously crazy and is only a temp fix. Now that i want three or more 1-many tables in my query, i would be talking about if statements for like 6 or more queries, insane.I apologize for the length of this, but i wanted to be perfectly clear. I feel like it should be not too hard, like using a record set for the form and not showing certain records or something, but i am not sure how to do it.Thanks so much. Dillon

I have a simple nested query that is not working as expected. My inner query returns 102 records but when I run with outer query I only get 96 records. Below is my query, I don't really want to pull the same fields from both tables but I was doing to test. The values that are missing are those that don't exist with the monthenddate 8/31/2014 - a left join should fix that but doesn't seem to be working ..
Code:
Select distinct a.entity, a.gl_account,a.profit_center,[Open Items_1].profit_center,[Open Items_1].gl_account,[Open Items_1].entity
from(
SELECT DISTINCT [Open Items].entity, [Open Items].gl_account, [Open Items].profit_center
FROM [Open Items]
)a
left outer JOIN [Open Items] AS [Open Items_1] ON
(a.profit_center = [Open Items_1].profit_center) AND (a.gl_account = [Open Items_1].gl_account) AND (a.entity = [Open Items_1].entity)
Where ([Open Items_1].MonthEndDate=#8/31/2014#)

I think I have just finished designing my database and I tried to test it and I couldn't enter any new records as it says "Can't enter data into blank field on "one" side of outer join" whenever I try and enter info and I don't know much SQL to work out what has happened. It probably causes this too but I also cannot select check boxes.
The form where I try and enter the info is called Crisis_support_workers v3. I have attached my database so you can look at what I have done.

I literally named my tables as follows and then literally typed the following into the query editor (SQL View):
SELECT * INTO FullJoin FROM LeftTable FULL JOIN RightTable ON RightTable.ContactID = LeftTable.ContactID
The error I get is, "Syntax Error in FROM clause"
What's my error?

I have the following Select Statement:
SELECTTenant.ID, Tenant.[First Name], Tenant.[Last Name], Tenant.Address, Tenant.City, Tenant.State, Tenant.Zip, Tenant.[Home Phone], Tenant.[Cell Phone], Tenant.[Work Phone], Tenant.[Rented Unit],
Tenant.[Security Deposit], Tenant.[Move In], Tenant.[Move Out], Tenant.TenantID, Tenant.UnitID, Tenant.PropertyID, Tenant.OwnerID, Owner.Company, Owner.ID AS Expr1, Property.[Property Address],
[code]....
Now, I know that something in the UPDATE statement does not match my select statement.What should my Update Statement be, in order to update all the columns in the joined tables?

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?

Attached is a pdf of the query window showing the relationships and table structure; (sorry for the quality) the linkage is also permanent at the relationship window. I created a form (columnar) of Rooms; loaded a subform (columnar) of the projects; and then loaded the students (tabular) as a subform on the projects subform. The data entry is flawless; tabs through each field and form to form in sequence.
After entering several rooms data I tested it at the query level by loading the three tables: rooms, projects, and students, and the permanentely established linkage with junctions came in automatically. I thought I was home free--but when I run the query, I get zero records.
When I attempt various joins, thinking this will yeild all records from the many tables and their match, I get "ambiguous outer joins" and it says to run a separate query and add it to the SQL Statement?
Thanks for any help,
Almost funtional in Ann Arbor........
Oh, and thanks Pat Hartman for the tip on linkage -- although I may have screwed it up anyway.

I'm new to the Access SQL world but I have a fairly complicated query that needs to be written for a project I'm working on. I am having trouble grasping the join concepts in access. My Query so far is:
SELECT u.user_logon_tx, ur.aff_sec_role_id, r.sec_role_ds, c.sec_cls_ds, o.sec_obj_ds, ci.aff_sec_cls_id, ci.sec_cls_item_ds, IIf(p.perm_in Is Null,0,p.perm_in) AS perm
FROM aff_sec_cls_item AS ci, aff_sec_user AS u, aff_sec_role AS r, aff_sec_user_role AS ur, aff_sec_obj AS o, aff_sec_cls AS c, aff_sec_obj_item_role_perm p,
ci LEFT OUTER JOIN p ON ci.aff_sec_cls_item_id=p.aff_sec_cls_item_id
WHERE u.aff_sec_user_id=1
And ur.aff_sec_user_id=u.aff_sec_user_id
And ur.aff_sec_role_id=r.aff_sec_role_id
And o.aff_sec_obj_id=1155
And o.aff_sec_cls_id=ci.aff_sec_cls_id
And o.aff_sec_cls_id=c.aff_sec_cls_id
And ur.aff_sec_role_id=p.aff_sec_role_id
And o.aff_sec_cls_id=p.aff_sec_cls_id
And o.aff_sec_obj_id=p.aff_sec_obj_id;
I have gotten it to work by using just the tables I'm doing the outer join on but when I add everything else I get the Ambiguous Join error. I wish I was using Oracle Thanks for the help.

I have a qry I need for picking the info for sending a series of letters out. I finally got it to work and now Im wondering if there is a better more efficient way. The qry I call to generate my report calls on information from 10 other queries and 7 tables. Some of the other queries are needed for other sub-forms that rely on the data. Is this something I should change? or just be happy it works???

I have a database in which i am trying to create some forms in order to search for records. The database contains several tables. Some tables are linked using a compound key while others have a single PK. I created the search form which has different searching criteria. Once a user selects the criteria, they hit the search button (there are different buttons for each type of search) the button opens up a form to display all the data. The problem is that there are many tables to report on. I created a form with a subform. The tables associated with the main form are all being retrieved fine. however the subform doesn't seem to work. I created the subform using a query to select all the fields from the desired tables, i gave this query a criteria based on the main form so that the Id's would match. (ie. Main form ID = Firstable in subform.ID)
I got a blank sheet in the subform when i used the search. i presumed that my query was not pulling records because of the referential integrity rules. i went in and changed the relationship rules so that it would include all records from the first table and matching records from the second table. (middle option in the list when editing a relationship) I now get the following error when i try to run the query.
"The SQL statement could not be executed because it contains ambiguous outer joins. To force one of the joins to be performed first, create a separate query that performs the first join and then include that query in your SQL statement."
Could someone please tell me what this means as the help is... how shall we say it.. written in true Microsoft Fashion.
And though it tells me how to fix it, i'm not really sure what it's telling me to do. I am using Access2003 But the Database is in an access 200 file format.
Thanks.
