Joining Tables With A Multi-Field PKey
Jan 5, 2005
(I know I posted this question before, but I fear it may have gotten lost in a thread so I am starting a new one)
I have created a multi-field pkey with the ModelDescription and VersionNumber fields. I did it the way that didn't require code as I could not find any online and am not versed enough in VB to do it on my own. I just highlighted both the fields and pressed the "Key" button.
My question is linking the tables. Should I just join them via the ModelDescription field? It won't let me join on both fields. Is it going to matter which field (ModelDescription vs. VersionNumber) I use to join the tables? I've never run into the need to have a multi-field pkey before.

I have two tables containing (let's say for simplicity) questions and attachments (pictures). I am trying to perform a union query to join all the questions and pictures into one report, but it won't let me union the attachment because 'the multi-valued field 'TableA.Pictures' cannot be used in a union query'.
I have searched and searched for a solution (and got kind of close) but i still can't get it to work. The best I can do is union everything like below, which gives all the questions as desired, but says #Error in the pictures column:
SELECT TableA.*
FROM TableA
Union
SELECT TableB.*
FROM TableB;
(Note tables A and B have the same structure, several yes/no and open text questions as well as one attachment field. )

I have 4 fields in a table that when combined must be unique.I know you can setup multiple fields as a combined key, but I don't really need these to be the key (I will auto number a unique key). I just need to make sure the same combination of codes is not entered twice.Do I set this up as multiple key fields anyway?

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

Hi
I have an Access database that contains 2 tables. Both of these tables have the same structure and have the same field names. So:
Table 1 Fields :
Name
Address
Telephone
Fax
Table 2 Fields :
Name
Address
Telephone
Fax
Is there a way to write a query, that will show the results of both tables in one go. (None of the information in table 1 is duplicated in table 2 - I want to show all records from both tables in one new table). So, if both tables had 3 records each, the query would return:
Name - Address - Telephone - Fax
jon-uk-12345-54321 (from Table 1)
julie-uk-21451-41541 (from Table 1)
paul-ir-98545-11241 (from Table 1)
pat-uk-99585-63362 (from Table 2)
phil-uk-99985-99631 (from Table 2)
ted-uk-44444-55555 (from Table 2)
These 2 tables need to be kept separate, so I can't copy and paste the records from Table 1 into the bottom of table 2.
The field names are the same in both tables.
Can this be done?
Many Thanks

I am building a simple task tracker to keep a record of tasks being passed back and forth between our team. The schema is fairly simple as illustrated in the image below.http://img2.freeimagehosting.net/uploads/f4f3a05c21.gifI want a recordset as follows out of this database (+/- few columns. But these are the most essential ones needed) -ixProject | Project.sTitle | ixTask | Task.sTitle | TaskHistory.dtEntry | sStatus | sEmployeeAssignor | sEmployeeAssigneeThis is basically a recordset of the history of the task (who assigned task to whom) and the status (assigned, resolved, closed). I can get the query to return the user id (ixEmployee) without any problems. But to display this in the interface I will need the employees name (sUsername).I tried the following query -SELECT Employee.sUsername AS sEmployeeAssignor, Employee.sUsername AS sEmployeeAssignee, Project.sTitle AS sProjectTitle, Task.sTitle, TaskHistory.dtEntry, TaskHistory.sDescription FROM(((Project INNER JOIN Task ON Project.ixProject = Task.ixProject) INNER JOIN (Employee INNER JOIN TaskHistory ON Employee.ixEmployee = TaskHistory.ixEmployeeAssignor)ON Task.ixTask = TaskHistory.ixTask)INNER JOIN Employee ON Employee.ixEmployee = TaskHistory.ixEmployeeAssignee <<< THIS IS THE PROBLEM LINE)WHERE (SELECT LAST(TaskHistory.ixEmployeeAssignee) FROM TaskHistory) = 1ORDER BY TaskHistory.ixTask, TaskHistory.ixTaskHistoryThis is the error I get -Join expression not supported.State:S1000,Native:-3530,Origin:[Microsoft][ODBC Microsoft Access Driver]Can someone explain how I can solve this problem? I am currently running two queries - one to retrieve the usernames, and the other to retrieve the history with the user id's - and replacing the user id's with usernames when displaying the records, but would like to have a cleaner solution.

Hello! I need to join 2 tables, 1 table with all of the fields, and another with just 2.
The link between the 2 tables is an ID field in field 2 wich is long integer.
The problem is, the ID field in table 1 that correlates to the ID field in table 2, is in the datatype text.
I cant change the datatype of the field in table 1 because it is a linked table to a txt file. And some of the values in there are dashes, indicating no ID. (not sure why).
So, is there ANY way to link the2 tables with the 2 different datatypes
Thanks in advance!

I am using MS Access 2007.
I have created a multi-valued field "Product Category" that lookups data items from a linked table. So, the Data Type for the multi-valued field "Product Category" is Number.
Now I want to change the Data Type of "Product Category" from Number to Text, and make a value list that I can type values in and can provide the same data items as the linked table.
How to change item source for the multi-valued field from a linked table to a list that I can type in values?
Is there a feature provided by MS Access 2007 can enable such a conversion?

Hey everyone. I have this situation: I work for a veterinary company and I have a project which includes 4 tables.The first one has a list of all of our clients.The other 3 are : a table for the year 2004, one for 2005 and one for 2006. Not every client visits us every year and I need a query which will make certain action (different sorts of calculations) with the number of animals that we take care of.
To make it more clear:
During 2004 one client with ID 12345 visited us with 3 animals.
He didn't show up in 2005 but he came back in 2006 with 4 animals.
Trying to do so I joined the tables properly (in my opinion one-to many) and I only get the sum if a client has visited us for all the 3 years. If he appears in just two tables or one I don't get a result.
This is the problem. Has anyone got a clue?
Thanks in advance

I am new to access and am having some problems. Here is what I have and what I want to do. I have one table that contains the ID number for a particular facility, facility name, and the sample location id number(s). Sometimes there is only one sample location id number and sometimes there are multiple. I have another table that has results of samples taken - it includes the facility id number, sample location id number, and the corresponding sample result. What I would like to do is join the data in the two tables so I have one table that shows takes the sample results from table 2 and combines it with the information in table 1.
Any help is appreciated

simple join my Main Data Compiling Table and Secondary Table Delete from Main Data table (Located Under main Content Tables). Basically I want it to run like a flat data table which I cannot do because I have too many fields. I want ability to further expand it in the future.Somehow I need a one to one relationship with Referential Integrity enforced with cascade Update Related fields and Cascade Delete Related fields. Problem lies in it tries to create a one too many relationship.Both Main1ID and Main2ID are AutoNumber with Main One being primary key.
I have created a tabbed Navigation Form to show what is currently happening the first Tab is from Client Demographic Form generated by fields from Main Data Compiling Table and Second from Floral Information Form generated by fields from Secondary Table Delete From Main Data Table.

how to do a particular thing in Access 2010 (I don't even know if it is possible).
I have a table named PRODUCTS:
ID_PRODUCT (primary key, autonumber long integer)
ALLOWED_OPTIONS (multi value text lookup field: "Option 1";"Option 2";...;"Option 9")
So I can store, for each different product, none, one, or more options to let the customers choose from.
I have a table named ORDERS:
ID_ORDER (primary key, autonumber long integer)
FK_CUSTOMER (foreign key, linked to the primary key of a CUSTOMERS table; represents the customer that places the order.)
FK_PRODUCT (foreign key, linked to PRODUCTS.ID_PRODUCT; represents the product that the customer has choosen)
CHOOSEN_OPTION (lookup text field; the customer must choose ONE option among those allowed for the product he has ordered)
The problem is that I would like the CHOOSEN_OPTION field to show as a combobox, listing the values stored into PRODUCTS.ALLOWED_OPTIONS, so that when a customer buys a product, he can choose only among the options allowed by that particular product.How can I manage a multi value field to populate a combobox, in which every item stays on its line? If I use, as a query to populate the combobox:
select [PRODUCTS].[ALLOWED_OPTIONS]
from PRODUCTS
where [PRODUCTS].[ID_PRODUCT]=[FK_PRODUCT]
I obtain an empty combobox.If I refer to the last field as [ORDERS].[FK_PRODUCT], Access asks me to type a value for "[ORDERS].[FK_PRODUCT]", treating it as an unknown parameter.I think that the problem is that when the combobox expands, the record is not committed yet, so FK_PRODUCT is unknown (NULL?). But this happens even if I commit the record typing something in FK_PRODUCT and then I re-enter the record and I expand the CHOOSEN_OPTION combobox, that is still empy although FK_PRODUCT exists, now.Is there a particular syntax to refer to a field in a record not committed yet (something like "THIS." or "ME.")?

Also, am I support to add a ‘join’ of tblA to tblB on BOTH the NAME and TYPE? I am so confused! Please help.Thank you very much. Joe

How would I go about joining tables with similar fields? I currently have three tables that show standings of teams (East, Central, and West). They all have the same fields:
East
Team Name
Wins
Losses
Ties
Points For
Points Against
Central
Team Name
Wins
Losses
Ties
Points For
Points Against
West
Team Name
Wins
Losses
Ties
Points For
Points Against
How would I combine them in a query so that all of the data from the tables are compiled into one table:
Overall Standings (East/Central/West)
Team Name
Wins
Losses
Ties
Points For
Points Against

I have a number of tables with different metrics. However, they all have a "Date" field in common, broken out at the daily level. Since some of my tables have different start and end dates, I'd like missing values to simply appear as "N/A". How I would do this with SQL?
I've attached a screenshot of the layout I'm going for. Each metric field (i.e. "Metric1", etc.) would be pulled in from a different table.

Searching for this information is difficult, because if it has a name I am wholly unaware of what to call this.
Say I have two tables.
Table1:
'Serial Number', 'Product Name', 'Size', 'Weight', etc.
Now I need to add a new table that I have to start inputting storage locations.
Table2:
'Serial Number', 'Warehouse', 'Bin Number'
I need to keep these separate, because the first table is also a transaction log.I created a query that pulls:'Serial Number' From Table1 and 'Warehouse' , 'Bin Number' from Table2. I also joined the tables by 'Serial Number' with Include All from Table1.
I made a form that gets all of the information from the query and adds combo boxes to allow users to enter data with less error. But the 'Serial Number' field of Table2 is never populated. Is there a better way? I do want to say that I have somehow accomplished this before but I can't figure out how I did it before.
I would like to have Table2 auto populate one row at a time as I enter locations into the form. I'm dealing with half a million records in Table1 and not all 'Serial Number' are valid/exist now.

Let's say that a table has been broken in two and I'd like to rejoin them with a query. Let's say 100 records in table1, 20 records in table 2. Here's a random example, I just made the names up off the top of my head:
PersonTable (100 records)
Person # (unique key)
Name
Address
SpouseTable (20 records)
Person # (lookup wizard to Table1, cascading edit/delete relationship, 1 to 1)
WeightOfSpouse
HeightOfSpouse
Many people aren't "married" and so have no corresponding value in the Spouse table. If I do an inner join on the two tables, on Person#, then it will cut the total # or returned records in the query to 20, to match the total in SpouseTable. Essentially, I want to append the results of SpouseTable to the end of the corresponding rows in PersonTable.
