Multiple Left Joins From Same Column
Sep 8, 2011
I have a table (Table A) that includes every number that's been dialed in our call center. I have another table (Table B) that has account numbers and three different phone fields for each account.
What I initially tried was to left join the Dialed Number column from Table A to all three phone number columns in Table B. This produces no results. If I only join Dialed Number to Phone Number 1 (for example), I get results, however, if the agent dialed one of the other two numbers, it's not going to show up.

Hi,
I have two tables:
tblListeners
-----------
ID (PK)
FirstName
LastName
etc
tblReference
------------
ID (PK)
ListenerID
ReferenceTypeID (FK)
ReferenceDate
etc
(Btw I am aware of the unconventional naming of the PKs but I'm running the B/E on SharePoint so I have no choice!)
So listeners have to periodically do a reference. What i want is a query that tracks if listeners either have not done a reference EVER or haven't done one for a while, but broken down by the FK in tblReference.
Here is my reasonably simple SQL so far:
SELECT tblListeners.ID AS ListenerID, tblListeners.FirstName, tblListeners.LastName, tblReference.ReferenceTypeID, tblReference.ReferenceDate
FROM tblListeners LEFT JOIN tblReference ON tblListeners.ID = tblReference.ListenerID
WHERE (((tblReference.ListenerID) Is Null) AND ((tblReference.ReferenceDate) Is Null)) OR (((tblReference.ReferenceDate)<DateAdd("m",-6,Date())))
ORDER BY tblListeners.FirstName, tblListeners.LastName;
In the current query the results ignore the FK so the so a listener will be missing if they have done one type of reference - i want them to be there (or not be there) for each type of reference. Hope that makes sense!
Now i know people may suggest a crosstab for this but: a) I don't get on with them and wouldn't know how to implement it and b) this will need to be in a report and I don't want to venture down the 'dynamic crosstab report' path!
Any ideas?
Cheers,
Bobadopolis

I am trying to create a simple Search form in Access where a user can select a desired record and query multiple tables using the inputs.
I would like them to be able to query Retailers, Distributors and Products.
The 6 tables are linked as follows:
Although some of these tables are not included in the query, they are required to ensure relationships.
Retailers -- Uses (RetailerID,DistributorID) -- Distributors
Retailers -- Orders (RetailerID,ProductID) -- Products
All retailers have at least one distributor BUT a retailer may or may not have ordered any products.
I have created my form but the query linked to the form is having some trouble. It is only selecting those records that have ordered products. For example, if I query a retailer name only and it does not have any ordered products, it will not display. Is there a problem with the table joins? The SQL for the query is displayed here:

Hello,
I have the following code for a multiple join:
INSERT INTO [AppendAllFields]SELECT [TreatyList].[Treaty] AS [Treaty],[MLAC 42 Treaty Xref ER].[tai treaty] AS [TreatyType],[txn 01/04].[Policy_Number]
(and more other fields from [txn 01/04] table)
FROM [txn 01/04] INNER JOIN [MLAC 42 Treaty Xref ER] ON TRIM([txn 01/04].[Policy_Number]) = TRIM([MLAC 42 Treaty Xref ER].[Polnum])
INNER JOIN [TreatyList] ON TRIM([MLAC 42 Treaty Xref ER].[tai treaty]) = TRIM([TreatyList].[TreatyNo]);
Basically, the txn 01/04 table has a corresponding Polnum field in the MLAC 42 table, and MLAC 42 table has a tai treaty field, which corresponds to TreatyNo in TreatyList table.
However, when I tried to run this, I got an Syntax error.
Could anyone please help?
Thanks!

I am trying to set up a file compare process. I load the two files into two "matching" tables (there is a key field). I have a series of queries which find any differences in the various fields and displays them. My problem is that one field (Field4 - a tran code) is coded 1,2,3 in one file and A,B,C in the other. I have set up a third translation table with two columns, each row showing the matching codes (1/A, 2/B, 3/C, etc). I want to find corresponding rows in FILE1 and FILE2 (matched on KEY) where tran codes (Field4) do not match (ie a "1" in File1 but NOT a "A" in FILE2).
I have not been able to get the two inner joins to work. Can some one help.
This is my last attempt:
FILE1: KEY-Field1-Field2-Field3-Field4
FILE2: KEY-Field1-Field2-Field3-Field4
(Field4 is the code that needs to be translated)
FILE3/numeric/alphabetic
1 A
2 B
3 C
4 D
SELECT FILE1.KEY,FILE1.Field4, FILE2.Field4
FROM
FILE1 INNER JOIN FILE2 ON FILE1.key = FILE2.key
INNER JOIN [FILE3] ON (FILE1.Field4 = FILE3.alphabetic)
WHERE FILE2.Field4 <> FILE3.numeric.
Hope this makes sense.

Okay, take three tables.
AreaTable
AreaID
AreaName
Percent
GangTable
GangID
Area_ID
Speed
MasterTable
MasterID
Station
Description
Area_ID
The Relationships
AreaTable.AreaID 1---------> (inf) GangTable.Area_ID
AreaTable.AreaID 1---------> (inf) MasterTable.Area_ID
Initially the query below used Inner Joins, however that limits my list, when i want to see ALL elements from the MasterTable no matter what, thus my inner joins became left and right joins as follows.
Simple Query: Query1
SELECT MasterTable.Station, MasterStable.Description, MasterTable.Area, AreaTable.Percent, GangTable.GangID, GangTable.Speed
FROM (AreaTable RIGHT JOIN MasterTable ON AreaTable.AreaID = MasterTable.Area_ID) LEFT JOIN GangTable ON AreaTable.AreaID = GangTable.Area_ID;
This should simply display All Records in MasterTable, (Multiple Times if Necessary) listing all the elements of AreaTable that are Linked to the MasterTable, and all elements from GangTable that are linked to AreaTable. It does this, and displays them nicely. But I can't edit the fields. I get the result:
1 | Station One | Area 1 | 45% | 204 | 1000
1 | Station One | Area 1 | 45% | 304 | 500
1 | Station One | Area 1 | 45% | 404 | 750
2 | Station Two | Area 1 | 45% | 204 | 1000
2 | Station Two | Area 1 | 45% | 304 | 500
2 | Station Two | Area 1 | 45% | 404 | 750
3 | Station Three | Area 2 | 75% | 254 | 800
3 | Station Three | Area 2 | 75% | 354 | 600
3 | Station Three | Area 2 | 75% | 454 | 700
So you can see that Area 1 has multiple Gangs (204,304,404) and Multiple Stations (1,2). If you do a simple set up like this, you'll find that you can't change the Description field (Rename "Station One" to "Hello World"). It just doesn't work, no matter which way I've tried, I can't seem to make a Query that presents all the information from MasterTable and All the Information IN AreaTable and All the Information in GangTable which will allow me to also edit the fields.
Any Help would be most appreciative, I'm tearing my hair out on this one.
Thanks,
Jaeden "Sifo Dyas" al'Raec Ruiner
ps - It just seems that with Junction Tables and all the many to many relationship designs I have tried, you'd be able to change the non-related fields. I understand that you can't change the "ID" fields, but the others should be editable.

Hello,
My query references 2 related tables: one for persons (PERS) and one for telephone/fax numbers and email addresses (CONT, for Contacts).
The relevant fields are:
PERS
pers_id (long) ---> primary key
pers_forename (text)
pers_surname (text)
CONT
cont_id (long) ---> primary key
pers_id (long) ---> foreign key
come_id (long) ---> foreign key
cont_number (text)
The foreign key come_id refers to a table for contact methods (COME), either "Phone (Home)", "Phone (Work)", "Mobile", "Fax" or "Email".
Now i want to list all persons with their home phone number and email address, also if they don't have one. It seems to be impossible to get it ...
I will explain what happens. Lets start simple: first list all persons with their home phone number (come_id = 1):
SELECT PERS.pers_forename, PERS.pers_surname, CONT.cont_number AS Phone
FROM PERS LEFT JOIN CONT ON PERS.pers_id = CONT.pers_id
WHERE (((IIf(IsNull([come_id]),1,[come_id]))=1));
This works fine. The IIf expression is necessary since we are dealing with an outer join: not all persons have a home phone number. If we would simply put "WHERE come_id = 1" then the query produces only the persons that have a home phone number.
But now i also want to see the email address (come_id = 5):
SELECT PERS.pers_forename, PERS.pers_surname,
CONT.cont_number AS Phone, CONT_1.cont_number AS Email
FROM CONT AS CONT_1 RIGHT JOIN
(PERS LEFT JOIN CONT ON PERS.pers_id = CONT.pers_id)
ON CONT_1.pers_id = PERS.pers_id
WHERE (((IIf(IsNull([cont].[come_id]),1,[cont].[come_id]))=1)
AND ((IIf(IsNull([cont_1].[come_id]),5,[cont_1].[come_id]))=5));
It seems perfectly logical: i added a second alias CONT_1 for the email address. Since this is also optional we have a second outer join, and the WHERE condition should also use an IIf expression.
The result is not correct though: the resulting recordset shows only the persons that have both a home phone number and an email addres or neither!
I have a lot of experience with SQL and queries, but i know i am not infallible. Nevertheless i am quite convinced that i should get all the persons: those that have a home phone number or an email address, or both or neither ...
I hope that someone of you can explain this.

I have this query in design view and in an asp page and it works fine:
SELECT dbo_feedback.*, dbo_origin.originName, dbo_product.prodname, dbo_category.catName FROM dbo_product INNER JOIN (dbo_origin INNER JOIN ((dbo_feedback INNER JOIN (dbo_category INNER JOIN links_cat ON dbo_category.catID = links_cat.CatID) ON dbo_feedback.id = links_cat.FeedbackID) INNER JOIN links_product ON dbo_feedback.id = links_product.FeedbackID) ON dbo_origin.originID = dbo_feedback.origin) ON dbo_product.prodID = links_product.ProductID;
BUT, I want to return all feedback entries, even if they have no matching Product or Category. :confused: When I change the inner joins to outer joins I get a syntax error in the browser window. I changed the join type in the relationship diagram in Access and tried to recreate this in query designer, but Access says the statement cannot be executed because of ambiguous outer joins.
FYI, one feedback can have many products, many categories, and only one origin. I have the joins correct and enforced.
Please help, thanks!!!

Hi. I have a question I'm hoping someone can help me with. I would like to take data from multiple columns and put the data into one column. Additionally, I do not want to exclude any data (union all) and I would like to group the resulting union by another field. For example:
Original data layout:
Column Headings: Sample Event, Depth 1, Depth 2, Depth 3,
1st Row Data: 1, 6, 9, 12, 9
2nd Row Data: 2, 7, 9, 8, 3
Desired data layout:
Column Headings: Sample Event, Depths
1, 6
1, 9
1,12
1, 9
2, 7
2, 9
2, 8
2, 3
So far I'm using the following SQL. What do I need to add or change to get my desired result of grouping the unioned depths by the 'sample event' field?
I appreciate any help anyone may have to offer. Thank you.
SELECT Depth1 AS Depths
FROM Depth_Velocity_Substrate_Correct
Union all
SELECT Depth2
FROM Depth_Velocity_Substrate_Correct
Union all
SELECT Depth3
FROM Depth_Velocity_Substrate_Correct
Union all
SELECT Depth4
FROM Depth_Velocity_Substrate_Correct
Union all
SELECT Depth5
FROM Depth_Velocity_Substrate_Correct

Hi
Is there a way you could look up multiple number in a query were the column will be a series of numbers/calculations?
E.g.
I would want to look for 13001,13002,13003, in a column where there would be calculation such
13001 * 246
13001 * 269
13002 849
etc
etc
Any help would be much appreciated?
Thanks

I have parent-child one to many data in one pair of relationships, and now I've been asked to see be able to find out what matches a defined regimen; each is also defined in a parent-child relationship.
Best is to show sample data. I'm going to show them as two tables, but the "Components" are actually in a parent-child relationship, e.g.,
PersonList -= Meds
Regimen -= Meds as well
Note that PersonList and Regimen do not really have any relation; we just want to see if things are being done one of the ways they are "supposed" to be done, without a slow manual check. It's worked as set up for reports, and I really don't want to change everything to a big long list of fields, one field per med for a lot of reasons (not least of which is that is denormalizing)
Quy 1 Result:
PersList T1Component
Andrew Med 1
Andrew Med 2
Brett Med 1
Brett Med 3
Brett Med 4
Charles Med 2
Duane Med 1
Duane Med 4
Quy 2 Result
Regimen T2Component
Goody1 Med 1
Goody1 Med 3
Goody1 Med 4
Goody2 Med 1
Goody2 Med 2
I'd like to be able to do two queries - one that are "OK" one that are not. Don't need to replicate the med list, just the regimen if matching..
"Good" would return
Person Regimen
Andrew Goody2 (he has med 1, 3, and 4)
Brett Goody1 (he has med 1 and 2)
"Bad" would return
Person
Charles
Duane
What they "almost match" does not matter; it tells people which ones we need to check into a bit more.

I am working with other data that has been created by someone else.
There are a number of columns with the same information in (a serial number). What I need to do is get this into one long column so that I can run other queries from it.
So far I have tried using this SQL:
SELECT A1-TX1 POWER AMPLIFIER 1
FROM SM_Cabinet_T
UNION ALL
SELECT A1-TX1 POWER AMPLIFIER 2
FROM SM_Cabinet_T
[Code] .....
But it is not working - Is it to do with the field names or am I entering something incorrectly?

I'm not familiar with listbox yet and i want to filter my form using it.
I have two separate listboxes which display "category" & "type" data from the same table.
Here is the situation i wanted for my listbox.
1. Select one data from "category" listbox.
2. Then it will automatically filter data from "type" listbox or it will list all related "type" data corresponding to "category" data.
3. Then select one data from "type" listbox and it will filter all related data on the form/sub-form.
Is it possible to do that way? Can i do it on multicolumn listbox instead of using 2 listbox?

I want to create the date from multiple columns to single colums. Just for example
table 1 (local purchase)
Itemname Date
Apple 12/01/2013
Mango 13/01/2013
Table 2 (Import purchase)
Item Name DAte
Apple 12/04/2013
Mango 08/06/2013
Now i want to make one query, which can you the date as follows when we give criteria = apple
Item Name Date purchase mode
Apple 12/01/2013 local
Apple 12/04/2013 Import
Means two dates from different table into one query column... One way in my mind to make one table for both tables.

I have a multiple column combo box on my form, that is correctly populating. When I make a selection, it displays the result from the first column. Bound column seems correct, as my table is being populated correctly.
1 - Can I display the values from both columns after the selection has been made?
2 - If not, can I choose to display the second column (not the first) after the user has made a selection?

I have a column that has a bunch of keywords they are separated by comma... so for each row of that column it will have a few different keywords example: lake superior, river, mountain, lake wollongong
I know its a bit of a nono with databases to have columns with comma separated text.. well so i read somewhere anyway but the document i have been handed to work has hundreds of rows in this column with up to 14 keyword entries.
I have a form that searches through Item's names based on 2 keyword boxes.
Here's the criteria in my query:
Is Null Or Like "*" & [Forms]![frmItemView]![SearchPhrase1] & "*" And Like "*" & [Forms]![frmItemView]![SearchPhrase2] & "*"
This will show all records when both keywords are blank, and filter records using the 2 keywords otherwise.
I have a form with two text boxes and have set the correct values as outlined in Evans post. I then have the query set to run via a button. I run it but it will only give back records for the entry i have put in the 1st text box. This would work well for me otherwise... mine is like this:
Is NULL or Like "*" & [Forms]![Searchtable]![Key1] & "*" And Like "*" & [Forms]![Searchtable]![Key2] & "*"
Searchtable being my search form
key1 being my first text box entry
key2 being my second text box entry

I'm working with a table of bird survival data I am trying to summarize in a query. I've got a bit of a roundabout way to achieve my goal, but I'm curious if there is a simpler approach.
Background : In my table, each row represents a day I check a given nest and includes a [Nest ID] (not unique, multiple visits to each nest), a [visit ID] (auto numbered, so it's a unique value for each visit at each nest), the calendar day I visited a nest [Date], and [Survive] (1 or 0) depending on whether a nest survived or failed.
I'm trying to convert this detailed table into one that is more concise. Instead of each visit to a nest being a row, each nest becomes a row with 4 fields: The Nest ID, the minimum date (the day I found a nest), the last day a nest was checked (Max[Date]), and the last day a nest was checked alive (essentially max date where survival=1).
My current solution is to run 3 separate queries. The first queries the max date where survival=1, the second queries the max and min dates regardless of any other criteria, and the third brings both queries together.
I am curious if there is a way to create the same final product in a single query rather than doing multiple ones as I have done?

I've created a access database containing multiple tables, theres one main table that will contain all the data compiled.
I then have other tables that contain some matching data but with an additonal column filled in,
I want to be able to pull the data from these other tables into the main table and compile it including merging some data into a single feild.
Effectively this is what the inputs will be:
Code:
Table 1
Ident Number Solution TRN
T0941A1 SLN019149 EFE0008
T0941B1 SLN019149 EFE0008
T0941C1 SLN019149 EFE0008
Code:
Table 2
Ident Number Solution TRN
T0941A1 SLN019149 EFE0167
T0941B1 SLN019149 EFE0167
T0941C1 SLN019149 EFE0167
Code:
Table 3
Ident Number Solution TRN
T0941A1 SLN019149 EFE0188
T0941B1 SLN019149 EFE0188
T0941C1 SLN019149 EFE0188
Then the main table i want to compile the data like this:
Code:
Table 4
Ident Number Solution TRN
T0941A1 SLN019149 EFE0008,TRN0167,EFE0188
T0941B1 SLN019149 EFE0008,TRN0167,EFE0188
T0941C1 SLN019149 EFE0008,TRN0167,EFE0188
i want it to show as 1 line item and compile the TRN numbers into a single feild per row rather than having duplicates.
