Connect Digest : 2009-05-30 : please vote!

Here are some issues I came across recently; most involve SSMS in some way, though Erland's assertion suggestion is a great one. And just to be clear, since I am seeing some accusations of distorting the fairness of Connect by "asking for votes," I am not asking anyone to vote blindly on these items (and it's clear from last week's results that people are NOT doing that).  I'm asking you to take a look at these issues and -- if they affect you and you care enough to do so -- vote on them.



Erland brought up a great suggestion to add true assertions to DML statements, which would have several benefits over triggers or rolling your own rollback mechanisms.

Object Explorer problem during attach operation

Last week I was attaching a largish database (~300GB) using CREATE DATABASE ... FOR ATTACH.  Unlike when restoring a database, where you can see the "Restoring..." state next to the database name in Object Explorer (and can still access other online databases), during this time, I would receive an ugly error message if I tried to expand or refresh the database list.  I believe this is because the attach operation places an exclusive lock on the table(s) underlying the sys.databases catalog view, and the *ad hoc SQL* that SSMS issues to display the list does not use snapshot or lower isolation.  I'm not sure why it has to behave this way.

Various Activity Monitor issues

Many people have complained about the way the new Activity Monitor replaced the previous version.  While there are many new and helpful ways in which the new feature works, a crowd has gathered complaining about some of the things that are still missing (or were taken away).

"distorting the fairness of Connect"? Connect is very inconvenient to navigate, so I really appreciate Aaron's effort. Thank you for the digest, Aaron, and please keep doing it!

Don't allow assertions. This can already be done in SQL with regular keywords.

Like Alexander, I also appreciate Aaaron's work to this regards. He is making our life easier and somehow educating us about the importance of connect to our community.
