Queries :: Identifying And Combining Rows Based On Matched Fields?
Jul 10, 2013
I have two tables. One table is a list of classes with the number of enrolled students:
Class............StEnrolled
English 1A........6
English 1B........12
English 1C........20
English 1D........25
Reading 1.........4
Reading 2.........15
And the other table is a list of "combined" classes (meaning they are, essentially, the same class and should be counted as such):
Class...........CombinedWith
English 1A.......English 1B
Reading 1........Reading 2
Using the first table, I currently generate a query (and build a report) that displays class enrollment levels. What I need is for this query to identify combined sections from the second table and display them as such:
Class........................StEnrolled
English 1A/English 1B........18
English 1C.......................20
English 1D.......................25
Reading 1/Reading 2..........19

Hello All,
I am trying to figure out the best was to combine fields from multiple rows into one row & field.
Example: I have a table that contains footnotes and products. With a simple query I would get the following 3 rows:
Product........................................... .......Footnote
V.I. Capital Appreciation Fund.................3
V.I. Capital Appreciation Fund.................5
V.I. Capital Appreciation Fund.................1
What I want is one row and the 3 footnotes combines into one field:
Product........................................... .......Footnote
V.I. Capital Appreciation Fund.................3, 5 ,1
Any help would be greatly appreciated.

So in my example you have a Weld (tblWelding_WeldingID) and each weld can have more than 1 consumable (tblconsumables_consumableID). have a third table that links the two, trackID,consumableID, weldingID)
What I need to be able to do in a report, is under the heading COnsumable, list the 1 or many consumables.
Also you select the consumable from a combo box..... if that just makes it that much harder...

I am a beginner in SQL, I have a problem regarding combining rows/ columns having value. Below is my example:
Table1:
1 123 23 43
1 234 3 431
2 34 34 34
2 54 3 123
3 1 32 32
2 341 1 32
Output Table:
1 123 23 43 234 3 431
2 34 34 34 54 3 123 341 1 32
3 1 32 32
or instead of combining rows, getting the result by combining columns with the same condition.How can I obtain such result?

I have 3 cross tab queries that are completely identical with the exception of the field that they pivot. Each field is searching for the same values just in different columns, with the end goal being to get the sum of the values for each pivoted column. I'm wondering rather than having 3 almost identical queries is there a way to use a crosstab to sum the values from each of the three fields rather that having 3 queries which then have to be aggregated in a fourth?
QUERY1
Code:
TRANSFORM
IIf(Count(PT_LEVEL.UNIT) Is Null,0,Count(PT_LEVEL.UNIT)) AS CountOfUNIT
SELECT
PT_LEVEL.INF_YEAR,
PT_LEVEL.INF_MONTH,
PT_LEVEL.UNIT
[code]...

I know how to concatenate fields in a query but have not done it with memos before. I have three memo fields and I want each to show up in one field with a bullet in front of each. Memo1 may be empty and memo2 and memo3 may have something or memo 3 may have some text but the others are empty so I need to be able to list the memos without the empty spaces. Is a query the best place to do this or in the report and how do I do it?

I have a big Excel file with payroll information about employees. Per employee per date, there are a couple of rows with mostly identical data (such as the employee's home address) but 2 differences: one will have paycode A with amount B, another will have paycode C with amount D, etc. I want to simplify the file to have 1 row per employee per date: in the example given that row would have paycode A with amount B as well as paycode C with amount D, in 4 separate columns.
I think I can technically solve this by creating Excel files per pay code/amount, and then linking them together by person and date, 1 by 1, through Access. This is feasible because there aren't that many different pay codes. But still, I was wondering if there was anyway to solve my problem in Access itself.

I'm creating a query which pulls together the numerical values of 32 separate fields. Each field has the potential to have a value in it ranging between 1 and 9, but most fields will be blank.
I want to prefix the value (if the value is not null) with a 2 or 3 character-long code relating to the field name.I then want to combine them all together in a query so I can easily copy and paste the output to a spreadsheet.Here is what I have so far, with just 9 of the field names, and it's already looking a bit clunky.
Code:
IIf(IsNull([zam_adm]),"","ADM") & [zam_adm] & " " &
IIf(IsNull([zam_cts]),"","CTS") & [zam_cts] & " " &
IIf(IsNull([zam_crs]),"","CRS") & [zam_crs]& " " &
IIf(IsNull([zam_IPB]),"","IPB") & [zam_IPB]& " " &
IIf(IsNull([zam_opr]),"","OPR") & [zam_opr]& " " &
IIf(IsNull([zam_owl]),"","OWL") & [zam_owl]& " " &
IIf(IsNull([zam_pmi]),"","PMI") & [zam_pmi]& " " &
IIf(IsNull([zam_wl]),"","WL") & [zam_wl]& " " &
IIf(IsNull([zam_sgt]),"","SGT") & [zam_sgt]
The output, unfortunately, is putting spaces between empty fields and I'm not sure how to prevent this in the syntax?

I trying to combine three columns that I have into one column without combining fields.
Currently what I have:
(see image below)
What I want:
ID-----MOC
##----name1
##----name2
##----name3
##----name4
##----name5
etc
The list I have will be much longer and will be changing frequently, which is why I can't just go on excel and manually do this.

I have a form (DropDown form) that has 3 drop down fields, you select your values from the drop downs and you would push a command button that runs an event procedure which runs a query (DropDown qry test). The user should have the option of picking any combination of fields to filter by. Or no combination, which would return all values in all fields. So I am basically using the form as parameter's for the query.
The problem I'm having is that my query is returning values for one field AND values for another field. Even if the other values selected are not in the same record. It's not combining the fields together to filter. For example: you pick a Project name and Supplier name, the query will return records that have the project name you selected but it will also return records with the supplier name you selected that have a different project name.
I've attached screen shots of the form and the design view of the query (the screen shot cut off the last column name. It is meant to say "Expr3: [Forms]![DropDown form]![Combo7]").
Using Windows 7,
Access 2010
Is there a way to select multiple values from the drop downs?

I have what is probably a simple thing to do in a qry but I just can't figure it out.
I have a spreadsheet that I imported into access. The basis of this spreadsheet is just basic company info.
Company|Address|City|State|Zip|Name
AAA Comp|123 Street|Anywhere|CA|90210|Mr. Somebody
ABC Comp|345 Street|Anywhere|CA|90210|Ms. Somebody
ABC Comp|345 Street|Anywhere|CA|90210|Ms. Anybody
ABC Comp|345 Street|Anywhere|CA|90210|Mr. Anywho
XYZ Comp|678 Street|Anywhere|CA|90210|Mr. Whosthat
For some companies, the information will repeat, like ABC Comp. What I need to do is to combine the rows with the same company information ie:
Company|Address|City|State|Zip|Name
AAA Comp|123 Street|Anywhere|CA|90210|Mr. Somebody
ABC Comp|345 Street|Anywhere|CA|90210|Ms. Somebody, Ms. Anybody, Mr. Anywho
XYZ Comp|678 Street|Anywhere|CA|90210|Mr. Whosthat|Pres.
Is there a way to do this in a qry?
Thanks in advance!

I have a question regarding ranked matches in a query. My data is set up as follows:
Item, Customer, Shipping Plant
65432, 104321, 221
65433, 104321, 221 etc.
For some items and customer combinations, there are multiple plants that can provide the same item item to a customer. I would like to create a ranked column that puts a 1,2,3 and so on for these occurrences. So if a customer get one item from only one plant, the rank would be 1, but if a customer gets the same item from two plants, the first would be rank 1 and second, rank 2 (order doesn't matter).

I am working with an Excel file of raw data aggregated from an annual customer relationship survey that has been sent out since 2010. The file has approximately 20,000 rows, meaning the survey has been taken around 20,000 times. Unfortunately, each time a customer takes the survey, it is included in the raw data as a separate entry. Therefore the file has numerous duplicate email addresses, corresponding with unique data for each time the survey was taken. Another issue regarding the data, is that in the first year the survey was sent out, the distribution mechanism "broke" and the survey was sent out multiple times (and completed multiple times) in the same year by the same customer, so the surveys are not necessarily uniformly distributed, if that makes sense.
I have been interested in isolating the common respondents (those who have taken the survey across multiple years, albeit not necessarily consecutive years). Up to this point, these respondents have been isolated manually using a pivot table, however I am now looking to enter the raw data into SPSS (a statistical analysis package), in order to view the drivers of these common respondents.
Therefore, I would like to be able to isolate these common respondents and the data corresponding with their surveys from the raw data in a separate worksheet or file. I have tried various formulas to do so in Excel to no avail. Is there anyway to accomplish this in Access or would a more complex database be needed?
Ideally the final product would have the common respondents' information from multiple surveys in one row and would be able to be filtered by feedback date (found in the raw data), so that hypothetically one could select a month and be able to tell how many customers considered to be common respondents completed a survey within that month.

I have three tables, with the following data (fields separated by "-" here):
Unit - Customer Number - Customer Name - Type of A/R - Total A/R
Unit - Customer Number - Customer Name - Type of A/R - Total Overdue
Unit - Customer Number - Customer Name - Type of A/R - > 90 Day Balance
I would like to combine these tables into one table with the following field names:
Unit - Customer Number - Customer Name - Type of A/R - Balance
When I append the data, it comes out like this:
Unit - Customer Number - Customer Name - Type of A/R - Total A/R - Type of A/R - Total Overdue - Type of A/R - > 90 Day Balance
I would like this new table to include all rows from the original tables, sandwiched on top of each other. As far as I can work it, the Append Query only adds the data as add'l columns; not as add'l rows. I tried changing the field names entirely, so that the final field in each table is called "Balance." However, I still get the same result as above - the columns are added, instead of rows. I swear there's a way to do this, I just can't remember it!

I have a database with all the hours employees have logged stored in the database. Our payroll company wants an excel spreadsheet that has very specific info in particular columns and fields on the excel spreadsheet, so I'm trying to design a query which will put the correct info in the correct fields per their system.
The challenge is, I have currently a query with Employee ID, Overtime Hours, and Regular Hours as separate columns.
I need to translate this to a query with a single column for hours and a separate column that designates those hours as OT or Reg, with two rows for those employees who have both types.
Current:
ID / Regular Hours / OT Hours
101 / 70 / 7.5
102 / 30 / 0
103 / 5 / 0
Needed:
ID/ Hours / Type
101 / 70 / Reg
101 / 7.5 / OT
102 / 30 / Reg
103 / 5 / Reg
I don't know how to create a query or a formula in a query to break out each employee row into multiple rows with different data in the hours column. It seems like there's something pretty straightforward that I've done in a similar vein but it doesn't seem to work - I can do the opposite and combine those hours by using the SUM function in a query, but I can't seem to break it out this way.

I currently have a calculated field that will result in either a whole number or a decimal. From there, I need to set up a field that identifies if the previous field is either a whole number or a decimal.I have tried several different formulas, but always seem to get an error or a query that does not return any results.

I have a query (A) as the data source for a report. That query (A) has a another query (B) as one of it source files.
How can I tell if query (B) has no output, so I can stop query (A) and the report attempting to run.

I have a statement as follows:
Code:
ohc: IIf(([oh]/[csqty])>1,[oh]/[case_qty] & " (LTSU?)",[oh]/[case_qty])
The intention was that it would add " (LTSU?)" to the calculated number where it was less than 1 (or not a whole number). Stupidm, me didnt account for fractions greater than 1 (ie 1.566). Just wanted to know how I can identify all 'non-whole' numbers in the above IIF statement.

I am trying to do the good 'ol sales report (query) to include customers with no sales.
I have a customers table, account number table, sales table & sales (line) detail table. (all linked in that order)
If I run a query to show customers (in the customer table) with account numbers, that works
An unmatched query to show customer without an account number works (but of course the unmatched account number field isn't shown).
How can I get the two two be shown together with the "unmatched" having a null or 0 for their account number?
I am guessing in principle, the resulting solution can be modified to show customers without sales alongside those with sales?

I'm trying to build a query that uses the information pulled from controls on a form called "CharacterCreation" - 2 of the controls are "Race" and "Class", and the form stores this data in a "Characters" table.The query needs to refer to the Characters table, and another table called "Modifiers".In this second table I have several numerical fields such as hp, str, etc, and I have two other fields called "Type_Modifier" and "Type" Among the Type_Modifiers are Race and Class, where their corresponding "Type" could be for instance Demon and Magician..
So the idea is that when I mark on the form (and thus creating the record in the first table) a Race of "Demon", and a class of "Magician" I want the query to refer to both of these fields, and sum the values in the second table where the "Type" is either "Demon" or "Magician" or whatever I decided to choose. I feel like I should be able to figure this out but I'm having a hard time..Here's an example of the SQL I've tried that shows nothing.
Code:
SELECT Characters.Char_Name, Sum(Modifiers.hp) AS SumOfhp
FROM Modifiers INNER JOIN Characters ON (Modifiers.Type = Characters.Class) AND (Modifiers.Type = Characters.Color2) AND (Modifiers.Type = Characters.Color1) AND (Modifiers.Type = Characters.Species) AND (Modifiers.Type = Characters.Race)
GROUP BY Characters.Char_Name, Modifiers.Type
HAVING (((Modifiers.Type)=[Characters].[Race]));
I also tried this, which I thought would work but it displays nothing as well.
Code:
SELECT Characters.Char_Name, Sum(Modifiers.hp) AS SumOfhp
FROM Modifiers INNER JOIN Characters ON (Modifiers.Type = Characters.Class) AND (Modifiers.Type = Characters.Color2) AND (Modifiers.Type = Characters.Color1) AND (Modifiers.Type = Characters.Species) AND (Modifiers.Type = Characters.Race)
GROUP BY Characters.Char_Name, [Type]=[Characters].[Race];

Hello,
I need to find a way to modify the following structure:
Name, Page, Grid
Acton Rd, G10, 12
Acton Rd, G10, 4
Acton Rd, G10, 8
Adams Ct, F6, 2
Into something like this:
Name Page Grid
Acton Rd, G10, '4, 8, 12'
Adams Ct, F6, '2'
What is the best way to go about tackling this?? I need to create this in a table so that I can export it from Access and into a .dbf to be used with another program.
Thanks,

I have an excel data file that is updated monthly (and I am not able to have the source file format changed of course) that will be my linked table for Access 2007. The file reports monthly data and adds the new month to the right of the historic in a layout like this:
Tree | Orchard | Province | Jan % red | Jan % green | # Limbs | Feb % red | Feb % green... etc so each month it adds 3 new fields to the data.
I have queries (rightly or wrongly) that will calculate the number of apples that month and report on those higher than a certain percentage. I would like to do this without having to create a static table to append to each month as the new data file will always show the full YTD results anyway (and I don't like to store data in my database).
I have a query that counts the number of fields in the raw data file and am wondering if there is a way to have access only run the number of queries required based on the number of fields. i.e. if 11 fields then run queries 1 thru 5, if 14 run 1 thru 6 etc.

I have a table similar to the following:
PatientID | LabID | LabDate | Result
001 | 55 | 01jan14 | 9.5
001 | 55 | 01feb14 | 10.0
001 | 55 | 01mar14 | 8.7
001 | 66 | 30jan14 | 11.2
001 | 66 | 30feb14 | 15.4
001 | 66 | 30mar14 | 13.0
002 | 55 | 01jan14 | 12.1
002 | 55 | 01feb14 | 9.9
002 | 55 | 01mar14 | 14.5
002 | 66 | 30jan14 | 16.5
002 | 66 | 30feb14 | 13.0
002 | 66 | 30mar14 | 10.0
Using a single-step Access query, I need to retrieve, for each PatientID, the most recent LabDate and Result *of a given LabID*. Thus, from the example dataset above, the desired output for LabID 55 is:
PatientID | LabID | LabDate | Result
001 | 55 | 01mar14 | 8.7
002 | 55 | 01mar14 | 14.5
I have searched this forum and others, but have not found an answer that I can directly tanslate to my situation. I have successfully written queries (with included subqueries) that retrieve the most recent of all the Labs, but have failed at obtaining a result dataset that contains only the records within a specified LabID.
For example, the query below fails because whenever the most recent of *all* the LabDates is not the same as the most recent of *the LabDates with a LabID=55*, the correct record is not included in the results. In the example dataset above, 0 records are returned.
SELECT a.PatientID, a.LabID, a.LabDate, a.Result
FROM Labs AS a
INNER JOIN (SELECT PatientID, MAX(LabDate) AS MaxLabDate FROM Labs GROUP BY PatientID) AS b
ON (a.PatientID = b.PatientID) AND (a.LabDate = b.MaxLabDate)
WHERE (((a.LabID)=55));

I have 2 seperate fields within a select query (In this example Field 1 - Country and Field 2 Number).
I have combined the 2 together into one field.
However a space appears within my results i.e
Field 1 Country Field 2 - Number
----------------- -------------------
England 4
USA 10
Combined fields:
Field 3 - Combined Country + Number
--------------------------------------------
England 4
USA 10
How can I remove this space within Field 3
