sql - How to retrieve scalar value from stored procedure (ADO.NET) -

-

Text after "

In the archived process, I just select a statement from sometable , select the select count (*) , Then from the client side (I am implementing the stored procedure using C # ADO .net SqlCommand), how do I get the count (*) value? I am using SQL Server 2008.

I am confused because count (*) thanks.

The return value of the stored procedure is not used as a parameter Advance, George

Or you suggested using Andrew as ExecuteScalar - or you have to change your code a little bit: 

  create process dbo.CountRowsInTable (@RowCount INT output) Select someTable end

and resume @RowCount = COUNT (*) Use this ADO.NET call to get the value: 

  (SqlCommand cmdGetCount = Using new SqlCommand ("dbo.CountRowsInTable", SqlConnection)) {cmdGetCount.CommandType = CommandType.StoredProcedure; CmdGetCount.Parameters.Add ("@RowCount", SqlDbType.Int). Direction = Parameter Direction.optput; SqlConnection.Open (); CmdGetCount.ExecuteNonQuery (); Int rowCount = Convert.ToInt32 (cmdGetCount.Parameters ["@owcount"]. Value); SqlConnection.Close (); }

Mark

PS: But in this concrete example, I just seem to be simple with implementing the ExecuteScalar and simple to understand Easy to do This method may work well, if you need to return more than a single value (like many tables or more matters than these matters).

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.

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. I name the image, then select that image to install Ubuntu in the Verbill box. The virtualbox will never...
