Queries :: Joining Data That Is Not Identical
Nov 25, 2014
I have a question regarding making a query with joint data that are not identical, as I'm not sure whether it's possible.
I have to look at certain serum levels at te start of a new medication regimen, and serum levels after 5 years.
I have one database with:
Patient number
Start date medication
Start date medication + 5 years
And one database with:Patient number
Date of blood test
Serum level molecule A
Serum level molecule B
What I want to do is make a query where the patient numbers are joined. The problem is that the "start date of the medication" and the "start date + 5 years" are not identical to the dates of the blood tests. E.g.: I have a patient that started medication on 01/March/2006, but he has had blood tests done every 3 months from 28/November/2003 till now, and not on 01/March/2006.
I would need the results of the blood tests (of molecule A and B) at the start of the medication and after 5 years, but if the test date differs by a day, Access already sees they're not identical.
I would like to have access select a blood test date that is as close to the medication start date as possible, within a time frame of e.g. +3 and -3 months. Is this at all possible?

Attached you will find an example with the problem.
The query is only searching identical data between both tables.
I want it to show results from all users, with all the devices each user has.
What am I doing wrong with the query?

I have two identical Access tables, for example tblDataYesterday and tblDataToday. The data from tblDataToday has updated data changes in it that are different from tblDataYesterday. I have a maximum of 100 fields to review. I want to compare the two tables and display in a query the differences between the data from both tables.

I have tried to combine data from 3 different tables (unrelated) to make a new one. However, as I understood I can not do this because these 3 tables are unrelated. In my case my 3 tables are for 3 labs' material requirements. I am planning that each lab will fill a form which directly related to there field and direct to me. That is why I intend to have separate tables for each. However, I want to create a table where I will be able to see all the requirements of different Labs altogether. This new table will be kind of Orders.

I have 2 tables: one for repairs and the other for the billing for those repairs. There is a foreign key(record_num) in the billing table to match the primary key(prikey) in the repairs table. This works fine as long as the unit repair has been completed.
Now an employee wants to see records even if they are not completed and wants the rate to be $0.00 if the unit has not been completed. But by this method there is no record in the billing table.
My problem is if I have the 2 tables joined then I only see records that match both tables. Here is my SQL for the query:
SELECT DISTINCTROW tbl_module_repairs.end_user, tbl_module_repairs.pickup_date, tbl_module_repairs.complete_date, IIf([pickup_entity]="Storm","APS Storm","APS Field Tech") AS [Repair Pickup], tbl_module_repairs.mfg_part_num, tbl_module_repairs.manufacturer, tbl_module_repairs.module_type, tbl_module_repairs.incoming_module_sn,
[Code] ....

I have an access 2003 database which holds data for lorry loads of timber delivered to different places at different prices and by different hauliers who get paid different ammounts.
I have tables that hold the prices for both haulage (sorted by the delivery location and haulier) and product price (sorted by the delivery location and the haulier.
I have two almost identical queries which give the haulage price for a particular load and the product price for a particular load.
Only the haulage prices seem to be returned - i have checked the settings and relationships in each of the tables invlovled and they appear to be that same.
Why would one query return the value and the other not???

I have 3 queries named Mech Final Equipment 3 Mth, Mech Final Equipment 6 Mth, and Mech Historical Final Equipment.They all have two fields-Final equipment and Sum of Sum of Down (calculating the number of minutes each piece of equipment was down in the time period selected).
My ultimate goal is to join the three queries to display a pivot chart that uses the Final Equipment as the category field and 3 Mth, 6Mth, and Historical as seperate data fields.What I have is a join query (Which I have named Mech Final Equipment H63 Joined)
Using this SQL:
Code:
SELECT DISTINCTROW [Mech Final Equipment 3 Mth].[Final Equipment], Sum([Mech Final Equipment 3 Mth].[Sum Of Down]) AS Duration
FROM [Mech Final Equipment 3 Mth]
GROUP BY [Mech Final Equipment 3 Mth].[Final Equipment]
UNION
[code]...
Which returns a table that looks like this:
Final Equipment, Duration
Ancillary Equipment, 225
Ancillary Equipment, 401
Ancillary Equipment, 1787
Brush Unit , 1252
Brush Unit , 2519
Brush Unit , 8004
And so on.What I need the table to look like is this
Final Equipment, 3 Mth, 6 Mth, Historical
Ancillary Equipment, 225, 401, 1787
Brush Unit, 1252, 2519, 8004
And so on, like a cross tab.I tried to do a crosstab query but I don't have enough fields.

Hello,
I have searched the forum and have found a lot of information however I am not sure just exactly what I am looking for.
Here is my situation.
It is a spilt DB.
I have a database with a form and a subform. The Primary Key in the form is unique to company A ie ID=CompanyA-1, CompanyA-2, and so on. There is a one to many relationship to the subform.
I have three of these databases in use, all identical execpt the Primary Keys. one is CompanyA, the others are CompanyB and CompanyC.
At the end of the month I want all companies, A,B,&C to send me their Backends so I can bring them all together into one database. The master database I want to bring all three backends into has the same Front End as the other three databases.
My question is what is the best way to bring all of the data together in one database so I can use the common front end to view it.
I am assuming that since the PK for each database is different they should all cometogether without much of a problem? If I can figure out how to merge them.
Thanks!
Fen How

I have multiple databases (one for each department). All 4 databases have an Agents table (tblAgents). Now I am creating another database that uses all of the agents on site. What I want to do is link all the agents tables and combine the values in one query.
Fields are:
UserID (PK)
AgentName
BadgeNumber (Employee Number)
Campaign (Department)
Coach (Supervisor)
HireDate
Status (Active / Leave of absense / Terminated)
The tables are linked to my new database. So logically, I'd think my next step is to query the tables. This is where I'm stuck. How do I say:
Agent = tblAgentsDepartment1.AgentName and also tblAgentsDepartment2.AgentName and also tblAgentsDepartment3.AgentName and also tblAgentsDepartment4.AgentName?
I'll have to do this for each field involved...

I have started working on an existing MS access application (Front-end & Back-end) built with VBA. The frontend linked to a back-end access database which contains only tables. Because of the nature of the work involving vehicles. Each user has their own copy of identical databases with their individual data stored in backend.
Right now we just copy each back-end database via ftp and store it as usr_backenddb_date.accdb Back end databases contain around 16 tables with most of them containing a autonumber field as a primary key. Further tables are connected with each other referencing the primary key as a foreign key .
I would like ideally create a function in vba that lets me select the database and merge all the data from that database to a identical central database. For the initial part, I am thinking of combining each individual table in each database and changing the autonumber field with SQL with possibly trying to cascade the change so the refrences remain intact.
Constant Access to one back end db via internet (or server) is not really possible as the users are able to connect to internet (network) only few times a day. There are over 100 backends (for each vehicle) with over 1000 records in each.

I'm trying to create an archiving routine as my database is becoming very large. For about 10 tables I want to shift certain records to an external database which would have the required 10 tables with the same table names and structure.
So far so good. I now want to automate everything using vba. I can see how to use the INSERT INTO statement but I don't want to have to name every field as there are hundreds. I just can't see how to do this.
If the table structures are identical how do I neatly shift a bunch of records from one to the other using code.

In my transaction table, I would like to find out the latest transaction dates of each family models. It sounds a simple Max function can get the desired result. However model number consists of the first 6 characters for the family model and the rest for the versions (variants). The Max function fails to work in this scenario. Is there any other way to group the model numbers once the 1st 6 characters are identical (the rest is ignored)?

I have two tables. One stores details of all money travelling from A to B, one from B to A.
I have created queries 'qry_A_to_B' and 'qry_B_to_A' to get each set of information.
Since there are User IDs in each table that don't appear in the other, I'm using the following two queries to return all the TO and FROM values. By using both LEFT joins, I appear to be getting all entries.
'A to B data
'------------
SELECT
[qry_A_to_B Yearly].ABUserID,
[qry_A to B Yearly].ABMonth_of_Year,
[qry_A to B Yearly].ABYearly_Sum,
[qry_A to B Yearly].ABMonthly_Sum,
[qry_A to B].ABMonth
FROM
[qry_A to B Yearly]
LEFT JOIN [qry_B to A]
ON [qry_A to B Yearly].[ABUserID] = [qry_B to A Yearly].BAUserID
GROUP BY
[qry_A to B Yearly].ABUserID,
[qry_A to B Yearly].ABMonth_of_Year,
[qry_A to B Yearly].ABYearly_Sum,
[qry_A to B Yearly].ABMonthly_Sum,
[qry_A to B].ABMonth;
'B to A data
'------------
SELECT
[qry_B to A Yearly].BAUserID,
[qry_B to A Yearly].BAMonth_of_Year,
[qry_B to A Yearly].BAYearly_Sum,
[qry_B to A Yearly].BAMonthly_Sum,
[qry_B to A].BAMonth
FROM
[qry_B to A Yearly]
LEFT JOIN [qry_A to B]
ON [qry_A to B Yearly].[ABUserID] = [qry_B to A Yearly].BAUserID
GROUP BY
[qry_B to A Yearly].BAUserID,
[qry_B to A Yearly].BAMonth_of_Year,
[qry_B to A Yearly].BAYearly_Sum,
[qry_B to A Yearly].BAMonthly_Sum,
[qry_B to A].BAMonth;
How can I join these two, to provide a list of ALL information, from all ten columns, regardless of whether or not someone has both a TO and FROM value? i.e.
If they only have a TO entry, I want to see it; the other five columns would be blank.
If they only have a FROM entry I want to see it; the other five columns would be blank.
If they have both, I want them to line up on one line.
However I try to phrase the query, I seem to miss at least some of the information from one or both tables.

Have 2 tables:
...TableA: 1 indexed field "Name" and many data fields in ~ 1000 records
...TableB: 1 indexed field "Name" and 2 data fields (DataB1 and DataB2) in about
~ 50 records
Tables currently have NO relationship set.
Want to add TableB data fields to TableA if Name are identical.
DataB1 and DataB2 fields are Not currently in TableA but could be added very easily.
Update (or whatever) will be done weekly where all previous data for DataB1 and DataB2 will be cleared from TableA before job is run.

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

is it possible to join these two queries together, so that the 2nd query appears at the bottom of the first?
Code:SELECT OEEModelMCTotals.Machine, OEEModelMCTotals.EventCode, OEEModelMCTotals.CodeDescription, OEEModelMCTotals.SumOfTotalTime, OEEModelMCTotals.Occur, OEEModelMCTotals.PlannedTime, [OEEModelMCTotals]![SumOfTotalTime]/[OEEModelMCTotals]![PlannedTime] AS [%Schedule], [OEEModelMCTotals]![SumOfTotalTime]/[OEEModelMCTotals]![Occur] AS Avg, OEEModelMCTotals.Output, OEEModelMCTotals.Throughput, OEEModelMCTotals.ValueAddedimeFROM OEEModelMCTotalsWHERE (((OEEModelMCTotals.EventCode) Not Like "n204" And (OEEModelMCTotals.EventCode)<>"n301" And (OEEModelMCTotals.EventCode)<>"n303" And (OEEModelMCTotals.EventCode)<>"x104" And (OEEModelMCTotals.EventCode)<>"x117"));
and
Code:SELECT OEEModelOtherTotals.EventCode, OEEModelOtherTotals.CodeDescription, OEEModelOtherTotals.Machine, Sum(OEEModelOtherTotals.TotalTime) AS SumOfTotalTime, Sum(OEEModelOtherTotals.Occur) AS SumOfOccurFROM OEEModelOtherTotalsGROUP BY OEEModelOtherTotals.EventCode, OEEModelOtherTotals.CodeDescription, OEEModelOtherTotals.Machine;
i have attached a spreadsheet with the outcome i am after....i dont want it in excel but have used this for my demonstration.
you will see at the bottom of the sheet i have highlighted the info added in blue.
can this be achieved ?
if so how please.

Hi,
My SQL is fairly basic so excuse me if this is something simple.
This isn't my database, I am trying to create a report on someone else's and it's a poor structure (sound familiar :-).
If I have created two queries; one of which selects results on students from one table and the other selects results on students from a completely different table.
This means I have two Hi,
My SQL ability is fairly basic so excuse me if this is something simple.
This isn't my database, I am trying to create a report on someone else's and it's a poor structure (sound familiar :-).
If I have created two queries; one of which selects results on students from one table and the other selects results on students from a completely different table, how do I combine these results into one query so I can run a report on it?
To outline the situation, I have two different queries with identical data types but from two different tables. I need to query these two queries and (possibly) link in another ‘student information’ table so that I can display the results from both queries as if they all came from the same place.
The addition of the extra table in the final query would only be so I can add extra student data into the final report.
Hope this makes sense!
Thanks,
Matt.

I'm new to access. Basically I've put this formula in a field within my query(Query A):
PERIOD: [YEAR] & "-" & [Month Number]
And I want to use this newly created field "Period" to join another table (Table A) without having to create another query.
PERIOD(Query A) -> PERIOD(Table A) = Month Name (Table A)
I need the month Name from Table A but because Period(Query A) is a formula I created, I don't know any way of joining it to Table A without creating another query. Is there another way...

I have a query joining two tables. TableInvoice in the query is Product number and Date purchased. TablePrices contains the same fields and contains prices (quarterly) over the past five years.
Joined by PONumber, I want the query to find the price charged for that date. Right now, if the Product number (TableInvoice) is not listed in TablePrices, it won't show. So, 100 Records might return only 80 if TablePrices does not have all of the Product numbers.
Is there a better way to return all 100 records in TableInvoice and show (Blank) price data if the item is not in TablePrices?

I am trying to use a join query to join two tables in order to create a form. I have done this on two other occasions in my database with no issues. Now it is only pulling the ID and I want it to pull the description. I have looked at the SQL view for the other queries that are similar as well as the design view and all of them are set up the same way with the exception that this new join query is pulling CertID rather than the CertDescription.
Is there any reason why it would be doing that? Is there an error that I could possibly be doing? It seems according to my notes that I have created all the queries the same but this last one does not pull the same info as the other queries.

I've got a query that uses a key from one table to pull back records from another.
My question is...
On the table with the key there is another field that I want to use to pull back data from the same table from above.
A bit more info...
Table one holds colleagues details
Table two holds records
Within table one there are 2 different fields that hold different ID's for the same colleague, currently I run two different queries to pull all data - I want to know if I can simply run one query that will return every thing?

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 2 identical database in terms of structure but it differs in data.
Basically I would like to import data from subDatabase to mainDatabase and ensuring that there are no duplicate records.
I have used the "link to datasource method" through importing the tables to have the "updating" function.
However, this method also means that the records in mainDatabase are also imported over to subDatabase which I do not want.
Is there a method to ensure that the records are shared/update one way only? (i.e. import from subDatabase to mainDatabase and not main to sub?)
