tsql - How can I SELECT where there is a specific link in a linking table or there is no link? -

-

I have two tables: 

  video --------- - ---- VideoID VideoGroup ID User ID

and 

  VideoTag -------------- Video ID Tag ID

I want to select all video group ID where producer is 1, 2 or 3 and there are 10 or 11 or 12 videos or videos attached or there are no tags related to the video. . Can I do it in the same question?

I think you want to join a left with an empty probe 

  Select VEE from V. videogrouped video. Videvideoid = vt.videoid at v.te.videoid where v.creatoruserid (1, 2, 3) and (vt.tagid is empty or vt .tagid in (10, 11, 12))

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.
