setting displayed data limits in MSaccess - ms-access

I need to find the top five customers in each month from a query. I have tried the Top Values return property but it sets limits on the entire data displayed. I just want a limit for each month.

SSRS show X amount of rows per group

I have a report that in which I have some grouping, I want to limit the maximum amount of rows per group to be 5.
For example: In a group of purchased items I want to show the last five purchased per category.
I've tried with Ceiling(RowNumber("GroupName")/5) as when doing page break after Nth row but I'm not quite getting the results I want. I tried in the filter group property setting the Top N but this doesn't work at all.
Is there a way at all to force RowNumber() function to equal a fix value?
I'm finding this harder than I thought it should be. I cannot modify the dataset, so I can't do this by query.
Any workaround or idea will be much appreciated
You may not be able to filter a tablix using the RowNumber function, but you can hide a row if its row number is (for example) greater than 5.
Use the *Row Visibility" properties to specify an expression like this:
=(RowNumber(Nothing) > 5)
To restart counting for every group, use the grouping name as the scope (instead of Nothing).

Hide Multiple Columns in SSRS Matrix

I have a Matrix report with some columns that are grouped by Month and Year in the Column Group. Now, these columns are being toggled by the Month Column as the Visibility Property is set to hide but toggled by the Month Column. But when the report is rendered, the hidden columns come out as blank and this defeat the purpose of the report, as seen in the images below. How do I do away with the blank spaces or which is the best way to meet this requirement?
I'm assuming you tried to set the individual column visibility properties...
You actually need to set the group visibility of your EnglishMonthName group to be toggled by [CalendarYear]. This will not hide the column completely (as you would not have anything visible to click on to get it back again) but it will collapse the data down and aggregate at the year level.
What you have done to hide your columns is actually working.
If you look at that WIDTH of each of the month then you will see they are of the same width. So according to your query you have the months appearing regardless of the corresponding data for that month.
I would do in two way depending on how the users would like it.
If possible and for better performance, I would alter the SQL query and do one of the following:
1. The months for which there is no corresponding data - I would remove the month names (or ID) as well
2. Rather than returning NULLs I would return a valid value like 0 or 'N/A' this will how the month as well as what the data actually is
To do it in the matrix you will need to alter the visibility of the month row as suggested by Alan Schofield

query to aggregat data by day to generate charts - rows unkown

I started building a search engine monitor. I'm pulling data from the google rest api into a mysql database with the following fields: date, search-keyword, domain, url, position.
Now I got into trouble querying and outputting the data for charting. The results go up and down, new results from google come into the list which haven't been there on the first day. However for charting I have to assign the first days at least blank values to output a chart.
What I do right now: First I select every domain showing up in the period. Lets say the for the keyword searchengine I get the domains wikipedia.org, ixquick.com, yahoo.com, searchenginewatch.com When I make another request for ever domain to query an array of rankings grouped by day. leading to the ...
Problem: Is where any query (mysql/nosql) which returns for each day an average and if where is no row a default value e.g. blank?
Result should look like:
dates={01/01/2014,02,03,04,05,06,07,08,...,31}
wikipedie={1,1,1,1,1,1,1,1,...,1}
yahoo = {"","",7,5,3,3,3,...,3}
You can create a date table, select the date range you'd like, and outer join your data to it, filling in 0s for values that do not exist for a given term/date.
Edit:
Some more details.
1) Create a table that has a row for every date +- 10 years (or whatever is appropriate). You can make this one column if you'd like, or many columns (date, month, year, etc.). The second approach makes this extensible if you want to summarize by various rollups in the future.
2) Outer join your table to the date table and use a NVL statement to coerce any null averages to 0.
3) Profit!
If your results are grouped by date, how can MySQL know there's (for example) 31 days in that month?
On the other hand, you can somehow fill the holes in PHP by loop through the array and fill a zero if the value does not exist.

MySql paginated results, find "page" for specific result

I have an application using a MySql database which is displaying a paginated list of records, to which to which the user is able to add new ones. I know how to get paginated results using LIMIT etc, but the question is how to go a specific page when adding a new record. If the page size is 20, and the user is viewing the first page, and they add a record which is 23rd (out of say 100), how do we determine which page to show the user.
So, essentially, given a page size and a specific record, how do I determine which "page" to show out of the pages. The total pages do NOT include all of the records for the table they belong to, but the criteria for getting them is static.
Edit:
I should have been more specific. The records contain a unique ID field and a string name field. The resultant records are sorted by the name alphabetically. Also, this is a java application.
The only thing I can think of is to select all the desired records sorted by name and then some how find the position in those results of the specific record. From that position the page number could be easily calculated since we know the page size, but I'm not sure if they is MySql syntax for getting the position of a record in the results.
The "dumb" solution would be to just grab them all and then in the application code (java), determine the specific records position in all the results. But is seems like their must be a more efficient way.
SELECT COUNT(*) as CNT FROM tbl WHERE name < (SELECT name FROM tbl WHERE id = 42)
After that you just divide CNT value to the amount rows per page and round (Math.floor()) it
Or you can even do that in sql:
SELECT FLOOR(COUNT(*) / 20) AS page_number ...

Selecting total results on a report

I have a matrix with several columns and rows. Example the rows are made up of names for a company and along the top are total sales, total calls, etc. So each row will have a number under each column, and at the bottom of each column is a total for each column. Currently i have the report set up that if you click on any of the numbers it pulls up a detailed report for those particular items. But if you select the total number it brings up the results for the first row's column. Is there a way to make it return all the items details when you click the total number for that column instead of what ever the detail would be for the first row of that column? Does this make sense?
You can use the inscope function to check whether you are in the value or total row. If you are not in scope then pass the correct parameter to the details report.
