ssrs 2008 - Avoid subreports in SQL Server Reporting Services by combining datasets to enhance performance -

-

I have an independent form report which is basically an overview of a company report.

The report looks like this: 

  ------------ Company XYZ ------------ - Address - Telephone - .. ** Contact * * - Brian - Caroline - Patrick ** Complaints ** - Complaint 1 - Complaint 2

This report brings together many company records Need to be able to run, resulting in a good print-out per company I have currently solved using a main report in which I have the choice of the main company Do not: 

  Select company from company

This main report is a table with a subreport in it. I provide the company as a subforport parameter.

In the sub-report, then I define different datasets (such as contact, complaint, ...) as follows.

  • Contact: Contact contact, name by name where companyid = @companyid
  • Order: Selection of Revenue by Order Please note that these datasets are not related to each other. , They are only related to the company

    However after running this report for many companies, it results in a terrible performance (I have 7 datasets in subreport, and if 50 reports are available for I The result is (7 + 1) * 50 queries.

    My question is, is it possible to eliminate the necessity of a subportport? I was trying to create a dataset which That's basically a combination of datasets which uses unions and adds each dataset as a new set of main query columns, although I think the use of lists with nested tables

    Is Cached Datasets Possible Solutions? If so, of course, as I can not find this ...

    thanks a lot!

HTML/CSS - Automatically set height width from background image? -

-
Long time ... I do not think it's possible, but I'm shocked before! I tag anchor tags, all of which are background images, all 300px wide but their height is all the difference, is it really set to do without typing altitude? Is it to set the dimensions of BG URL? Thank you! I do not think people understand - my mistake is to hurry the question. Here is the code as an example: # ago -1 {width: 300px; Height: 410px; Background: url ('/ image-1.jpg');} # East -2 {width: 300px; Height: 420px; Background: url ('/ image-2.jpg');} # Pre-3 {width: 300px; Height: 430px; Background: url ('/ image-3.jpg');} # Pre-4 {width: 300px; Height: 440px; Background: url ('/ image-3.jpg');} & lt; A href = "#" id = "ex-1" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "ex-2" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "pre-3" & gt; & Lt; / A & gt...

c - What is the address of buf (the local variable in the main function)? -

-
I had exercise with programming in c or classes and I followed the question: Is Buf (local variable in main function)? Either enter the answer in hexadecimal format (like 0x 8 "digits" 0-9 or A-F, 0xbfff0014) or in decimal format. Note here that we want the address of the buff, not its content. The code looks like this: int main (int argc, char * argv []) {while (1) {four buff [1024] = {0}; Int r; .... I then started the code and put the built code in the buff [1024] line and in Typed Gdb p & amp; Buf and it gives me results: 0xbffff0f0 But when I use it in this quiz it gives me the result that this value is wrong. My question is this: Is this the name of the Buff variable (P & E)? Or if not, why not? Exercise is done on the virtualbox machine, so I think everyone should be the same address There is no correct numerical answer, the address may vary from one time to another, it is a programming drill that you say the following three...
