I don't know how to put my requirement in words but let me explain it with a table and output that I desire
The table looks like this
Package LanguageUsed UnitsSold
lmn basic 43
xyz pascal 20
abc basic 50
cba c 20
Output I want is
LanguageUsed UnitsSold
basic 93 43+50
pascal 20 20+ nothing
c 20 20+ nothing
I need to display number of packages sold in each language
How can I do this in MySQL?
I need to display number of packages sold in each language
You can do:
SELECT languageUsed, SUM(UnitsSold)
FROM yourTABLE
GROUP BY languageUsed

I have 3 table. final,milestone and milestonewp consider that the three tables is foreigned key like milestonewp<--FK--milestone<--FK--Final .Then I have a column for determining the average of the milestonewp for a certain foreign key. Then getting that average to be average again to be displayed to the final table.Here is my visual representation
milestonewp
condition | mile_id
20 1
20 1
30 1
21 2
21 2
31 2
40 3
30 3
50 3
How can I average the average that the chart above will produce?
I'm trying to work on this
select avg(milewp_condition)
from logs_pms_r_milestone_wp
where mile_id=1;
but i dont have any idea how it can produce for the other mile_id
EDIT
The above code will produce something like this
avg(milewp_condition)
0
0
0
so then, i also want to average that 3 rows.
If I understand well this should be what you look for:
SELECT AVG(milewp_condition)
FROM logs_pms_r_milestone_wp
GROUP BY mile_id;
If you want to average all, just do:
SELECT AVG(milewp_condition)
FROM logs_pms_r_milestone_wp;

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,

tbl_ChildrensMedical.MaxPercentFPL, tbl_ChildrensMedical.MinAge,
tbl_ChildrensMedical.MaxAge, tbl_ChildrensMedical.Program
FROM qry_CombinedIndividual
INNER JOIN tbl_ChildrensMedical ON qry_CombinedIndividual.qry_Enrolled.Patient = tbl_ChildrensMedical.Patient
WHERE (((qry_CombinedIndividual.AgeAtApp)>=[tbl_ChildrensMedical].[MinAge]
And (qry_CombinedIndividual.AgeAtApp)<[tbl_ChildrensMedical].[MinAge])
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 (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]));
Table
id name(varhcar)
2 15
3 15,23
4 1315,424
5 1512,2323
6 23,15,345
7 253,234,15
I need to find out those values which contains 15 which mean i need 2,3,6,7 not 4,5.
Above is sample data, in real time it can be any number.
Can anyone please help me?
If your database is small, consider using find_in_set function:
select * from your_table
where find_in_set('15',name);
Consider change the model to master-detail table to increase the speed if you have a big table.
This is the kind of relational model you could adopt to make this an easy problem to solve:
TABLE: records
id
2
3
4
5
6
7
TABLE: values
record_id value
2 15
3 15
3 23
4 1315
4 424
5 1512
5 2323
6 23
6 15
6 345
7 253
7 234
7 15
Then you can query:
SELECT DISTINCT id FROM records
INNER JOIN values ON records.id = values.record_id AND values.value = 15
This is the only way you can take good advantage of MySQL's query optimizer.
Not that it's impossible to do what you're trying to do, but it kind of misses the point.
If you're already storing data in this format, you should write a one-time migration to transfer it to this "normalized" format in the programming language of your choice, using something like Java's split or PHP's explode.
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.
