\n

I came across an interesting bug in Management Studio in the latest Katmai CTP today – when a connection disconnects from a database, SSMS doesn’t release the shared database lock that it holds. This prevents any operations that need exclusive database access (like a RESTORE<\/FONT>) and can be somewhat disconcerting if you don’t realize what’s going on. Try executing the following in SSMS in the November CTP:<\/P>
\n


\n

USE<\/FONT><\/FONT> <\/FONT>master<\/FONT>;
<\/FONT><\/FONT>GO<\/P><\/FONT>
\n

CREATE<\/FONT><\/FONT> <\/FONT>DATABASE<\/FONT> MySSMSTest<\/FONT>;
<\/FONT><\/FONT>GO<\/P><\/FONT>
\n

USE<\/FONT><\/FONT> MySSMSTest<\/FONT>;
<\/FONT><\/FONT>GO<\/P><\/FONT>
\n

CREATE<\/FONT><\/FONT> <\/FONT>TABLE<\/FONT> test <\/FONT>(<\/FONT>c1 <\/FONT>INT<\/FONT>);
<\/FONT><\/FONT>GO<\/P><\/FONT>
\n

USE<\/FONT><\/FONT> <\/FONT>master<\/FONT>;
<\/FONT><\/FONT>GO<\/P><\/FONT>
\n

DROP<\/FONT><\/FONT> <\/FONT>DATABASE<\/FONT> MySSMSTest<\/FONT>;
<\/FONT><\/FONT>GO<\/FONT><\/P><\/BLOCKQUOTE><\/FONT>
\n

And you’ll see:<\/P>
\n


\n

Msg 3702, Level 16, State 4, Line 1
Cannot drop database “MySSMSTest” because it is currently in use.<\/FONT><\/P><\/BLOCKQUOTE>
\n

It works perfectly in SQLCMD in the same CTP, and also in SQL Server 2005. You can work around this by doing something like:<\/P>
\n


\n

ALTER<\/FONT><\/FONT> <\/FONT>DATABASE<\/FONT> MySSMSTest <\/FONT>SET<\/FONT> <\/FONT>RESTRICTED_USER<\/FONT> <\/FONT>WITH<\/FONT> <\/FONT>ROLLBACK<\/FONT> IMMEDIATE<\/FONT>;<\/P><\/FONT><\/FONT>
\n

GO<\/FONT><\/P><\/BLOCKQUOTE><\/FONT>
\n

Not exactly ideal – but, hey, it’s only a CTP. This has already been reported in Connect<\/a> as issue 320135<\/a> – I added a workaround.<\/P>
\n

I’ll post any further bugs that I find here as well as making sure they’re on Connect.<\/P><\/FONT><\/FONT><\/p>\n","protected":false},"excerpt":{"rendered":"
