SQL conditional SELECT -

-

I would like to create a stored procedure with parameters that indicate which field should be selected.

I would like to pass two parameters "selectField1" and "selectField2" each as bools.

I want something 

  SELECT if (selectField1 = true) field 1 Do not select ELSE field 1 (selectField2 = true) Field 2 of field 2 from ELSE table   
 Want the ability to return the areas with permission, which means that the number of returning areas should also be dynamic. It will work with 2 variables. More than anything else will be confused. Choose Selection (selectfield1 = true and selectField2 = true) Select field 1, from field 2 to the table end (selectField1 = true) Start Select from Table 1 Field 1 Select first (selectField2 = true) SELECT field from end field 2 < / Code>

This example will help with dynamic SQL multiples is true, at least 1 column is assuming. 

  announcement @ sql varchar (MAX) SET @sql = 'select' IF (selectField1 = true) BEGIN SET @sql = @sql + 'field 1,' end if (selectField2 = true) BEGIN SET @sql = @sql + 'field2,' end ... - DROP ',' @sql = SUBSTRING (@ SQL, 1, LAN (SSLL-2) SET @ SQL = @ SQL + 'FARM table' EXEC (@sql)

Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

Visual Studio 2005: How to speed up builds when a VSMDI is open? -

-
Using Visual Studio 2005, if I open the test in VSMFI and try to run the tests, then sometimes the projects are ready. However, they run very slow. CPU 99% waste and output window VS Shows things associated with compiling it. Is there any way to fix this? It does not make any sense. It is not necessary to upgrade that we are a viable alternative to those people who have to deal with the legacy code. Did you try to upgrade SP1? I do not know of any specific problem in this area, but this will be the first change I tried to do.

booting ubuntu from usb using virtualbox -

I am trying to install Ubuntu on a USB, the problem is that I do not want to repeat the boot once, I want to keep my windows, but I want to boot Ubuntu using the virtualbox and USB to the Ubuntu Want to use my hard drive, but how? The virtualbox will not recognize USB as a hard drive when installing an ISO In virtualbox, you have to create a virtual hard disk. Make a USB drive and tell the virtual box to install a virtual hard drive that you just created. EDIT: To answer some more questions: In the new Virtual Disk dialog, click the button next to the location field, click on the button Virtual Disk on Flash Drive To access, click the arrow next to Save in the Select File in the window next to Save In, and you can access your flash drive from there. I recommend setting the image to be allocated dynamically, because the size of your flash drive is not available disk space.
