sql - Best way to add a new column with an initial (but not default) value? -

-

I have to add a new column in a MS SQL 2005 database with an initial value. However, I do not want to automatically create a default barrier on this column. At the time that I correct the column default / initial value, but it can change over time. Therefore, instead of accepting a default in future access to the table, a value must be specified.

The best I can come up with: 

  ALTER TABLE tbl ADD COL INTEGER NULL Update tbl SET col = 1 ALTER TABLE tbl ALTER COLUMN COL INTEGER NOT NULL

This is slightly ineligible for tables on large scale (100,000 to 1,000,000 records).

I used to add columns with a default and then with the removal of the default barrier. However, I do not know what the default barrier is, and it will not use Cisco and it will put the database in specific knowledge.

Please, should be a better way.

me ALTER TABLE tbl ADD COL INTEGER CONSTRAINT TEMPname DEFAULT 1 First, and <(Probably within the transaction) they are specified after.

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. 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. I name the image, then select that image to install Ubuntu in the Verbill box. The virtualbox will never...
