So I have a query that is a Top Nth aggregate query, and I have another query built from that one that returns all the offices/locations grouped for each of the top sales. I want to make a report that counts the number of offices associated with each of these top Nth ID values that are returned in this query. I want to use a domain aggregate expression in text boxes on the report so that I do not have to spend time each month looking up those IDs to determine what needs to go into the expression.
So is there an expression I can add to the second query that will assign a number descending number to the IDs?
The first query looks like: /
ID# ITEM Sold /
765 Lawnmowers 75 /
764 Weed trimmers 64 /
etc
the second query looks like: /
ID# ITEM Sold Location /
/
765 Lawnmowers 75 New York /
765 Lawnmowers 75 Maryland /
765 Lawnmowers 75 Ohio /
765 Lawnmowers 75 Virginia /
764 Weed trimmers 64 Florida
764 Weed trimmers 64 north Carolina /
I need:
/
ID# ITEM Sold Location IDGroup# /
765 Lawnmowers 75 New York 1 /
765 Lawnmowers 75 Maryland 1 /
765 Lawnmowers 75 Ohio 1 /
765 Lawnmowers 75 Virginia 1 /
764 Weed trimmers 64 Florida 2 /
764 Weed trimmers 64 north Carolina 2 /
please help. thanks! i am pulling my hair on this one!
what i am trying to do is be able to report the number of items sold (done), how many locations sold the item (need dynamically) for a given time period.
i was trying to use an DCount expression but if I use the Product ID, it does me no good because these figures change monthly (this is all based from a Top Ten query to begin with)
i know i confuse myself with this question :)
To answer your question, yes it's possible. You can use the Switch function. Ex:
Switch("LawnMower",1,"Weed trimmers",2) etc. Of course this requires you to put an entry for every unique value in the table and is pretty much a horrible id for anything but a throw-away query with a small number of groups.
A more orthodox approach would be to create a lookup table with two fields: "Item" and "Group". Make item the primary key and make "Group" a AutoNumbered field. Next you will need to create a Select Distinct query to get the unique items in the original table. Turn this query into an append query and pipe the values into your lookup table (sorting however you like). The autonum field will automatically assign sequential IDs to these records.
Now you can just take your original query and add a join to your lookup table to pull in a group id.
Addendum: If more than one item can be in a group, simply use the ITEM make the ID field a non-unique numeric long and then key the entries manually (it shouldn't take too long since it will be unique entries). Either way, with this approach you should be able to maintain your groups with relative ease going forward.

Is there a way to use an Over and Intersect function to get the average sales for the first 3 periods (not always consecutive months, sometimes a month is skipped) for each Employee?
For example:
EmpID 1 is 71.67 ((80 + 60 + 75)/3) despite skipping "3/1/2007"
EmpID 3 is 250 ((350 + 250 + 150)/3).
I'm not sure how EmpID 2 would work because there are just two data points.
I've used a work-around by calculated column using DenseRank over Date, "asc", EmpID and then used another Boolean calculated column where DenseRank column name is <= 3, then used Over functions over the Boolean=TRUE column but I want to figure the correct way to do this.
There are Last 'n' Period functions but I haven't seen anything resembling a First 'n' Period function.
EmpID Date Sales
1 1/1/2007 80
1 2/1/2007 60
1 4/1/2007 75
1 5/1/2007 30
1 9/1/2007 100
2 2/1/2007 200
2 3/1/2007 100
3 12/1/2006 350
3 1/1/2007 250
3 3/1/2007 150
3 4/1/2007 275
3 8/1/2007 375
3 9/1/2007 475
3 10/1/2007 300
3 12/1/2007 200
I suppose the solution depends on where you want this data represented, but here is one example
If((Rank([Date],"asc",[EmpID])<=3) and (Max(Rank([Date],"asc",[EmpID])) OVER ([EmpID])>=3),Avg([Sales]) over ([EmpID]))
You can insert this as a calculated column and it will give you what you want (assuming your data is sorted by date when imported).
You may want to see the row numbering, and in that case insert this as a calculated column as well and name it RN
Rank([Date],"asc",[EmpID])
Explanation
Rank([Date],"asc",[EmpID])
This part of the function is basically applying a row number (labeled as RN in the results below) to each EmpID grouping.
Rank([Date],"asc",[EmpID])<=3
This is how we are taking the top 3 rows regardless if Months are skipped. If your data isn't sorted, we'd have to create one additional calculated column but the same logic applies.
(Max(Rank([Date],"asc",[EmpID])) OVER ([EmpID])>=3)
This is where we are basically ignoring EmpID = 2, or any EmpID who doesn't have at least 3 rows. Removing this would give you the average (dynamically) for each EmpID based on their first 1, 2, or 3 months respectively.
Avg([Sales]) over ([EmpID])
Now that our data is limited to the rows we care about, just take the average for each EmpID.
#Chris- Here is the solution I came up with
Step 1: Inserted a calculated column 'rank' with the expression below
DenseRank([Date],"asc",[EmpID])
Step 2: Created a cross table visualization from the data table and limited data with the expression below
I have searched and found discussions and solutions to similar problems, but not quite or as complex as I'm trying to figure out.
I have an access table which consists of two columns Draw Number and Number Drawn as shown below. Draw Number is repeated 20 times, to correspond to the 20 numbers that are drawn in each particular draw.
I'm trying to figure a way to determine the most frequent occurring combination of numbers (5 numbers) for all of the draws in each of the 20 number sets. So for instance, 12341 occurs n x, 12342 occurs nx, 12343 occurs n x, etc.
I've created parameter queries which allow me to search for different number combinations from 2 to 10 numbers, and they work OK returning the number of occurrences of a combination of numbers that I input through a simple UI. But the goal is to figure out pragmatically what the optimum combination of numbers.
Hope this makes sense. And by the way, there are 36 million or so rows in the table. The para queries work quite well however; it takes just over a second to return results for each number added. So, query two numbers = 2 second wait, three numbers = 3 second wait, etc.
I've been thinking about a loop of some type but don't know how to get started? Processing time isn't an issue; can take a day if required!
This is written in VBA and has an assortment of queries, temp tables, etc to get the job done.

This part confuses me: I'm trying to figure a way to determine the most frequent occurring combination of numbers (5 numbers) for all of the draws in each of the 20 number sets. So for instance, 12341 occurs n x, 12342 occurs nx, 12343 occurs n x, etc. – Newd 21 hours ago
^What do you mean five numbers? No where in your sample data do I see 12341. Please explain using the data you have, and give expected results using that data. – McAdam331 21 hours ago
drosberg - clarification:
thanks for the response. It is an Access application, but as a first-time poster Stackoverflow recommends tags?
By five numbers I mean the most frequently occurring group of five numbers (I used five as an example, could be groups of 2 to 10 numbers) which occur in each draw, where a draw consists of 20 drawn numbers from a total of 80 numbers. So the data that I posted was intended as an example. The sample provided only has 50, 51 in common. I can plug 50 and 51 into the parameter query and it will tell me that this combination occurs 60,000 times (or whatever), but perhaps 50 and 57 occurs 65,000 times.
If i was to do this manually, and assuming I'm looking for the most frequent 5 number combination I would enter the following in the parameter query: 1,2,3,4,1 group = 30,000 occurrences 1,2,3,4,2 group = 31,000 occurrences 1,2,3,4,3 group = 31,050 occurrences 1,2,3,4,4 group = 29,050 occurrences etc........... etc...........
but I would have to do this for every combination of 5 numbers that can be derived from the numbers 1 thru 80. I'm hoping to have program do the work!!
thanks

I wrote a post a while ago about generating permutations with and without repetition using Excel. Perhaps you can use it.
https://michiel.wordpress.com/2015/03/29/permutations-with-repetition-using-excel/
Here's how it works. I am using strings, but you can easily modify that for numbers (since you say you need 5).
You can use the MID function to grab a single char from a string, and generate permutations from it.
=MID(Pattern,MOD([N]/[P],Length)+1,1)
N revers to the column N
P refers to the horizontal row (1,4,16). You can generate these with a formula like =4^.
After putting in the code, you can make a list of all permutations in Excel and in the cell next to it generate a sql query that you can perform as well from VBA.
Example: Looking up Access database in Excel
Or find a commercial tool like http://thingiequery.com/
I don't know if there's any open source tools for it.
I'm thinking that you should consider:
Say there are 100 balls.
Setting up a table to have one row for each "Draw number" with 100 columns one for every possible number each column has type boolean.
When you look to see which draws had number 23 you just add a
WHERE Column23 = true.
For numbers 23 and 56
WHERE Column23 = true AND Column56 = true
This should massivel simplify and speed up your SQL.
You set up a table with every possible combination of numbers.
You run SQL to find the counts.

I am having difficulty trying to make a calculated field that I need. So here is what I am trying to do:
I have a query that combines the information based on three tables. The most important fields that for the application are as follows:
Family Income Age Patient
15,000 18 Yes
28,000 25 No
30,000 1 Yes
From here I want to make a calculated field that gives the correct program the patient was enrolled in. based on these fields ie:
Program Minimum Income Maximum Income Minimum Age Maximum Age Patient
Children's 0 20,000 1 19 Yes
Adult 0 12,000 19 65 No
Non Patient 0 20,000 1 19 No
Adult 2 12,000 50,000 19 65 No
Etc.
to create:
Family Income Age Patient Program
15,000 18 Yes Children's
28,000 25 No Adult 2
30,000 1 Yes Children's 2
I know I can use IIf to hard code it in to the field, but then it will be really difficult for other people to update the information as the guidelines change. Is it possible to have the information stored in a table? and use the information on the table form etc, or will I need to use IIf
Any Ideas? is it possible to dynamically create the IIf in SQL using VBA while pulling the information from the table?
EDIT:::
Thank you for your response and for formatting my tables, I still have no idea how you changed it, but it looks amazing!
I tried to add the SQL you added down below, but I was not able to make it work. I'm not sure if I made a mistake so I included the SQL of my Query. The query currently returns 0 values, so I think I messed something up. (The real Query is embarassing...I'm sorry for that). Unfortunately, I have done everything in my power to avoid SQL, and now I am paying the price.
SELECT qry_CombinedIndividual.qry_PrimaryApplicant.[Application Date],
qry_CombinedIndividual.qry_PrimaryApplicant.[Eligibility Rep],
qry_CombinedIndividual.qry_PrimaryApplicant.Name,

AND ((qry_CombinedIndividual.[Percent FPL])>=[tbl_ChildrensMedical].[MinPercentFPL]
And (qry_CombinedIndividual.[Percent FPL])<[tbl_ChildrensMedical].[MaxPercentFPL]));
Also there are many different programs. Here is the real Children's Table (eventually I would like to add adults if possible)
*Note the actual table uses FPL (which takes family size into account, but is used the same as income). I am again at a total loss as to how you formated the table.

SCHIP (No Premium) No 0 210 1 19
SCHIP (Tier 1) No 210 260 1 19
SCHIP (Tier 2) No 260 312 1 19
Newborn No 0 300 0 1
Newborn (Patient) Yes 0 300 0 1
Children's Medical Yes 0 200 1 19
CHIP (20 Premium) Yes 200 250 1 19
CHIP (30 Premium) Yes 250 300 1 19
Do I have the correct implementation for the table I have? Or should I be changing something. I can also send more information/sample data if that would help.
Thank you again!
I just created some tables with your sample data and used the following SQL. Your 3rd 'patient' doesn't match any of the ranges (Age 1, Income $30K)
SELECT tblPatient.PatName, tblPatient.FamInc, tblPatient.Age, tblPatient.Patient,
tblPatientRange.Program, tblPatientRange.MinInc, tblPatientRange.MaxInc, tblPatientRange.MinAge,
tblPatientRange.MaxAge, tblPatientRange.Patient
FROM tblPatient INNER JOIN tblPatientRange ON tblPatient.Patient = tblPatientRange.Patient
WHERE (((tblPatient.FamInc)>=[tblPatientRange]![MinInc] And (tblPatient.FamInc)<=[tblPatientRange]![MaxInc])
AND ((tblPatient.Age)>=[tblPatientRange]![MinAge] And (tblPatient.Age)<=[tblPatientRange]![MaxAge]));
My question about SEARCH query performance.
I've flattened out data into a read-only Person table (MySQL) that exists purely for search. The table has about 20 columns of data (mostly limited text values, dates and booleans and a few columns containing unlimited text).
Person
=============================================================
id First Last DOB etc (20+ columns)...
1 John Doe 05/02/1969
2 Sara Jones 04/02/1982
3 Dave Moore 10/11/1984
Another two tables support the relationship between Person and Activity.
Activity
===================================
id activity
1 hiking
2 skiing
3 snowboarding
4 bird watching
5 etc...
PersonActivity
===================================
id PersonId ActivityId
1 2 1
2 2 3
3 2 10
4 2 16
5 2 34
6 2 37
7 2 38
8 etc…
Search considerations:
Person table has potentially 200-300k+ rows
Each person potentially has 50+ activities
Search may include Activity filter (e.g., select persons with one and/or more activities)
Returned results are displayed with person details and activities as bulleted list
If the Person table is used only for search, I'm wondering if I should add the activities as comma separated values to the Person table instead of joining to the Activity and PersonActivity tables:
Person
===========================================================================
id First Last DOB Activity
2 Sara Jones 04/02/1982 hiking, snowboarding, golf, etc.
Given the search considerations above, would this help or hurt search performance?
Thanks for the input.
Horrible idea. You will lose the ability to use indexes in querying. Do not under any circumstances store data in a comma delimited list if you ever want to search on that column. Realtional database are designed to have good performance with tables joined together. Your database is relatively small and should have no performance issues at all if you index properly.
You may still want to display the results in a comma delimted fashion. I think MYSQL has a function called GROUP_CONCAT for that.
I am developing an SSRS report with the following dataset. There is a filter for 'Period'. It is a multi-select filter. Data is grouped by 'Account' field. I need to display Total Expense for each group (which was easy). I also need to display 'Budget' on the same group level. The problem is the budget data is redundant - see below.
Say for the first group (Account=100 AND Period=201301), Sum([Budget]) would generate 200, which is not true. I can use the Average function which helps if user selects only one Period from the filter. If they select multiple values (e.g. 201301,201302) then the average will be (100+100+150+150)/4=125, which would be wrong because it has to be 100+150=250. I don't want to average among all rows in the returned dataset.
ID Account Period Expense Budget
1 100 201301 20 100
2 100 201301 30 100
3 100 201302 10 150
4 100 201302 40 150
5 200 ...................
So, how do I write an expression to make this happen?
A dirty workaound would be to eliminate redundant values in the Budget column so I can safely use Sum([Budget]) w/o worrying about duplication. The updated dataset would look like this:
ID Account Period Expense Budget
1 100 201301 20 100
2 100 201301 30 NULL
3 100 201302 10 150
4 100 201302 40 NULL
5 200 ...................
Please advice for either approach. Thank you.
The most elegant way is to use the FIRST() aggregate function.
=FIRST(Fields!Budget.Value, "MyAccountGroupName")
There are some situations where this won't work. Then you need to move the logic to your query as you describe or you can get fancy with embedded code in your report.
I would follow your "dirty workaround" approach. You might possibly be able to achieve the result just inside SSRS with some fancy calculations, but it will be totally obscure.
