Query Joined Tables
Jan 24, 2005
What I'm trying to accomplish is probably really simple that I just can't get it to work. I have set up the relationship properly, I think. Here is what it looks like:
tblProjects(ProjectID[PK],ProjectName, ProjectType, ProjectDate)
tblMembers(MemberID[PK], MemberName)
tblRoles(RoleID[PK], RoleName)
tblProjMemb(ProjMembID[PK], ProjectID[FK], MemberID[FK], RoleID[FK])
Each project will have three different member roles. Here is what I'm trying to get from my db:
myQuery(tblProjects.*, tblMembers.MemberID As Role1ID, tblMembers.MemberName As Role1, tblMembers.MemberID As Role2ID, tblMembers.MemberName As Role2, tblMembers.MemberID As Role3ID, tblMembers.MemberName As Role3)
I need Role1ID = Role1 If when tblProjMemb.RoleID = 1. I need to create a column for each of the three member roles and have the name of that person in that column.
I'm not sure how to accomplish this. Any help is much appreciated. Thanks!

I can not, or not allowed to enter data in fields in a query built from three tables that are jointed by a common field with the same name. The parent table is linked to another Access data base as is one child table the other is local data. Also, I am not able to view the child table data when viewing the parent table.

Hello all,
I have made a crosstab query that is sporatically making duplicate counts. I'd like to know how to fix the problem, but more importantly - I'd like to know why and how my query is giving me these results so I can avoid making this same mistake again.
The relationship is set up so that all records from one table are returned, with only matching records from the other - so no problems that way as far as I can see. This is my crosstab query that is giving some counts of the same record as being matched sometimes two, three, or even four times:
TRANSFORM
Count([Testing DB].[DB_ID]) AS [CountOfDB_ID]
SELECT
[Testing DB].State, [Location].[North], Count([Testing DB].[DB_ID])
AS [Total Of DB_ID]
FROM [Testing DB] LEFT JOIN [Location] ON [Testing DB].[Address] = [Location].Address
WHERE (([Testing DB].[Window Length]) Is Not Null))
GROUP BY [Testing DB].State, [Location].[Size]
ORDER BY [Testing DB].State, [Location].[Size]
PIVOT Format([Date],"mmm-yyyy");
When I do a simple query for a list of the records being counted by this query, I can see the duplicate entries and can eliminate them simply by adding "Distinct" to the select statement - but I haven't had any luck adding any kind of distinction with this crosstab that will do the same.
How can I eliminate duplicate counts of records in my crosstab? If anyone has a suggestion, it would be much appreciated.

I have a query, that I have a criteria to show appointments in the past (< Date()) but one result doesn't show up although the appointment end date is a past date, it only shows up when I fill in a field that is in another table that is joined and part of the query. But there's no criteria there for it to not be null.

I have an Access Table with about 28,000 Automobile dealerships across the country shown. I've joined a new/small phone contact table to this to keep up with our phone contacts with the dealership and followup efforts. When I search/filter on the dealership table all is fine. However when I search/filter on the phone contact table with a few test entries, I get nothing at all. I supposed that after joining the tables, I'd be able to do a search on the field named follow up date and find/filter today's date or other dates and locate which dealerships to contact when the correct date arrives. But nothing.

I have two tables in my database
Agents
Zip Codes (linked table)
If I create a query and then a form off the query that includes fields from both tables - Access will not let me add new records.
Ultimatley what I am looking to do is have a zip code field in the Agents table that I fill in and then it will automatically look at the zip codes table and then fill in the zip code, county, & state in a different area of the form.
I tried using fields from both tables and tried a query using fields from both tables and it will not let me add new records.
I have a relationship between the fields in both tables.
What am I doing wrong. I know this can be done.
Any help would be great!!!

Hi,
I have problem with pdf-ing a report that has record source coming from a query namely from the two tables joined based on the same of several fields (foreign keys).
I have PDF coding that would turn Access report to PDF report. It has no problem when the report's record source is from one table only.
Just wonder if anyone who might have a similar issue would like to share with me some help. Is it normal that PDF doesn't work if the report comes from joined tables in Access?
Thank you in advance

I am using the following query to identify rows in one table that have no match in another:
SELECT MAS.MASID
FROM MAS LEFT JOIN IVT ON MAS.Field1=IVT.Field1
WHERE ((IVT.IVTID) Is Null);
MAS is one file with MASID as the key.
IVT is the other file with IVTID as the key
This provides me a list of the rows in MAS with no match in IVT.
I now want to delete these rows in MAS so we can process the other fields in the table.
what is the syntax for the delete statement? I can't get the join to fit in correctly.
Help!

Hi,
I am getting information on products stored in a query. I want that query to check a couple tables to see if an item is linked through all of them. If it is not listed in the last table (catalog) I want it to be shown.
Code:Catalog tableVolume Prefixprodno Price15 - CE 0218 9.9915 - CE 0722 3.7215 - CF 0218 12.3615 - CF 0091 14.00Source TableSource MediaCM70904 15 - CE
Code:Batches QueryCustomer Number Prefixprodno Source716933 0218 CM70904716933 0408 CM70904
This is the Select Statement I'm using, which gets the 0218 but not the 0408 I want
Code:SELECT (fieldnames......)FROM [Batches] INNER JOIN ([Source] INNER JOIN [Catalog] ON [Source].[Media] = [Catalog].Volume) ON ([Batches].Source = [Source].[Source]) AND ([Batches].Prefixprodno IN ([Catalog].Prefixprodno))WHERE [Batches].[Customer Number]=716933;
If I do NOT IN I get both 0218 and 0408. I just want 0408. I'm sorry if this seems confusing but any help would be amazing at this point =/

I a report based on query based on joined tables. Im using FK and PK accordingly in the tables and have a junction table.
I've attached a sample (removed all unique identifiers for privacy in case you're wondering).
Table structure as follows:
Employees tbl - Junction (License Link tbl) License No tbl, License Class tbl, Endorsements tbl
So the query runs on all of these tables.
When I build a report on the query, Simon shows up Six times. I suspect because he has six endorsements.
How do I produce a report on this table/query structure so that I get:
Simon.
Class, 1,2,3,4,5
Endorsement F,R,T,W,DG

Hi...
I have an Access query, which gives me the "orphans", between two tables.
They look like this
tblSurveys tblJobs
* *
Grade -> JobGrade
Paytype -> JobPayType
Survey -> JobSurvey
other... -> other (including jobcode)
Linked as indicated, (all from tblSurvey to those matching tblJobs)
with criteria, WHERE jobcode is null
Ie. an unmatched query between tblSurvey and tblJobs.
Now I want to delete those from the survey where there is no jobs.
But when I change my select query to a delete query, I get the error:
Cannot delete from specified tables
My SQL (access generated) looks like this:
DELETE tblSurveys.*, tblJobs.JobCode
FROM tblSurvey LEFT JOIN tblJobs ON
(tblSurveys.Grade = tblJobs.JobGrade) AND
(tblSurveys.PayType = tblJobs.JobPayType) AND
(tblSurveys.Survey = tblJobs.JobSurvey)
WHERE (((tblJobs.JobCode) Is Null));
That first line looks wrong...
Anyway, if someone can help me to delete these I will be forever grateful.
The way I understand it, a delete query should look more simple... ie
delete * from tblName where (and type the intricate stuff here)
Thanks in advance
Reenen
(BTW: I posted this on Ozgrid as well, but they are bigger on Excel there, and response times are better here. Apologies in advance)

I have created a query that show all the records form Material Estimation table that the job number matches in the Production Table, that the AssDate is between the frm_Export_Data dates.
This the SQL view of the query.

FROM [Material Estimation] INNER JOIN Production ON [Material Estimation].[Job Number] = Production.[Job #]
WHERE (((Production.[AssDate]) Between [Forms]![frm_Export_Data]![FromDate] And [Forms]![frm_Export_Data]![ToDate]));
I want to delete all the records in the Material Estimation table that show up in this query.
Is this possible?
Thank you...

I have to get the Top 5 for each Col, grouped by group, but all in one table. What I did was split Col1 to one query with a return of 5. And also did that with Col2. But now I have to join them, and only a few records pop up, those which have the same group name, all others were excluded...what can I do?

hi
I have a query I'm creating that is using a joined view. I'm joining two tables and whereas the first contains unique data to each field the second contans class information so for example while all users are unique many may be assigned to the same class. When i use the join it therefore dupliactes all the class information in the query.
how can i set up the query so that the class information is only output once and not duplicated along with a user every time ?
cheers

I have a client database that has recently had multiple duplicate entries. I need to reduce or negate this erroneous activity. I have a client table where I record amongst others, the following;
key
[christian_name]
[family_name]
[dob]
......
I believe that to prevent duplicate entrie via form I have created an additional field called "unique" given it as a unique index which I want to have populated with the joined fields first_name & last_name & dob (IE johndoe01/01/90), and then as user enters a new client it wont allow a duplicate.
However I need to fill all the existing customers (3600+) with the relevant joined existing data. If I create an expression I can cajoin the fields in a select query but when I try to make an update query the same syntax comes up with empty fields.
select query sql that worked to show field ...
SELECT divers.christian_name, divers.family_name, divers.dob, [christian_name] & [family_name] & [dob] AS Expr1
FROM divers;
update query that was empty ..
UPDATE divers SET divers.[unique] = [christian_name] & [family_name] & [dob];

I have a Table with 6 fields, 2 are named Initial and Surname. Is it at all possible to have a combo box on a form with these to fields "joined" with the alphabetical order on the Surname. I understand that using a query will not work as the result is based on an expression

I have some experience doing 'Update Query' using two different tables but I'm having a hard time doing an 'Update Query' using 3 tables.
I have my source table TP05XY with the fields 'Mark' 'Date' 'UTM_Edig' and 'UTM_Ndig'. Mark and Date are my primary keys (they together uniquely ID each record). I have my Observations table with the fields 'Mark' 'Date' and 'Obs_ID'. The last table is Locations with 'Obs_ID' 'UTM_E' and 'UTM_N'.
I want to update my fields UTM_E and UTM_N from UTM_Edig and UTM_Ndig. However, to do so, I have to go from my TP05XY table, through Observations table to update Locations table. Table TP05XY is joined to Observations through 'Mark' and 'Date' and Observations table is linked to Locations through 'Obs_ID' field.
I have tried a few options without success ... anyone knows how to do it?
Thanks,
Josée

I am using Access 2010.I have a table that I am using to pull my data from other tables and a query.My table is called tblMyData.One of the field names is level1. This field points to another table, and gives the user the choices for states (examples California, Texas, Maine).
Another field name is level2. This field points to another table and give the user the choice for type of customer (examples Business, Consumer)
The field name level3 points to a query. The query, qryFinalChoice matches up the choices based on level1 and level2.for example, the user can pick California for level1, business in level2 and California Widgets or Los Angeles Clothing store in level3 (plus about 20 other choices).
If the user picks Texas for level1, business in level2, business in level2 and Houston rugs, or Texas style restaurant in level3 (or about 15 other choices).
-I am recording 1 for California on level1, 2 for Texas and 3 for Maine in level1.
-I am recording 1 for business and 2 for consumer on level2.
The query qryFinalChoice has all the combinations for state, business or consumer, and lastly business name or consumer name.
-qryFinalChoice has line1 to match up the choices for level1 in my table.
-qryFinalChoice has line2 to match up the choices for level2 in my table.
-qryFinalChoice has line3 to match up the choices for level3 in my table.
I do not want any of the Texas business names appearing when the user picks California, or vice versa.
My SQL in my tblMyData tab for level3 looks like this:
Select line1 from qryFinalChoice where line1=1;
I am able to get all the line items where California is a selection.How do I change my SQL to pull all the line1 choices where I have selected from level1, and all the line2 choices where I have selected from level2 automatically based on my pulldowns?

I'm looking into storing query data in temp tables for my reports run better. From what I'm reading, it seems best to have the temp tables in a separate db, and to break the links to avoid bloating of the FE database. I'm unsure how to do this with VBA, especially since my temp database will be password protected. When do I break the link - when I close the FE database?

I am using collect data via email process to collect data by email, purpose is to update not to add new records but to update. The condition for update is to have data from one table only.
I have 4 tables data from which should be sent by email. These tables are related. I made a query based on tables and query is update-able. When I use this query, wizard does not give option of updating the data but only of adding new records.
I tried to first make a make table from a make table query but that too have the same result.
Any ways to make treat these tables in a single table? Almost all fields except one shall be just to read and one field shall be updated.

I have one database that I am working on and within it there are several Tables. 2 of the tables have similar information on various organisations and I need to query these 2 tables to get a simple mailing list of ALL organisation addresses and the main incumbent there.
Within Access (2007) and in the SQL View window, I have made a simple query to give me a list of all the organisations and incumbents but cannot get it to work correctly. Is there an easy way to get this information out of the 2 tables? I realise that the SQL in SQL View has to be formatted differently. I have also tried the Microsoft Query Wizard but that doesn't work either as it gives in a side by side list which is useless to me.
The Field names that are required are as follows:
<Incumbent>, <Organisation>, <Address1>, <Address2>, <Address3>, <County>, <Postcode>,

I have a form which will be used as the basis to print a label.
It is bound to a query and when I open the form I pass over a 'where' condition to return 1 record. I then use the query to produce a report/label.
What I want to do is to update the form/query without updating the underlying tables to the query.
