It would be useful if you had said how you tried to re-attach the database
and what error number and message you recieved. There may be a more
fundamental underlying error why you can not do this!
You can re-attach a database using the sp_attach_db command in SQLCMD the
syntax of this can be found in books online or at
http://msdn2.microsoft.com/en-us/library/aa259611(SQL.80).aspx. If you dont
have the log file you can use sp_attach_single_file_db.
With SQLExpress you can also use the CREATE DATABASE with the FOR ATTACH
clause.

|||Hi,
I think it will be easier to help you, if you'd tell which error
messages you get. Also, what makes you believe that the databases has
been detached? Detaching a database is something you'll have to do, and
not something that just happens.

Hi, thanks for your replies, i fix the bugs by reinstalling SQL
server, then attaching the mdf.

|||For understanding what happen i can explain the problem from start to
end ...
when i complete development tasks on my db using sql express managment
studio, i right click on db --> shrink, the server hanging for tens
of seconds, afterthat it return error message, it is long msg but i
read its header like 'can't determine rows or index in sysindexes or
like this',,, i follow the instruction to solve until it routing me to
microsoft support, finally microsoft online help return sorry no idea
about this error.
i think the error happen in the master db..
after that the db disappeared from the db list..
i explore the location of mdf,ldf i found it intact.
then i try to attach my db but without benifit, it return to me error
msg like the msg when you try to attach already attached db.
then i think to add new db with the same name, the server again return
error!
So i concluded from this case my db name & alias already found in
master db or whatever sql registry, but not physically attached to
mdf,ldf files.
when i attach my db to another sql server on other pc, it work fine &
no data lost.
So i uninstalled my sql server then reinstall & attach, finally it
work fine ...
that is all.
i know it can be solved by another way if i expert in dba admin.
thank you all, & welcome to reply if any one get the idea on dba admin
basis & knowledge...

My guess is that you have auto close set for this database and it closed
because there was no connections to the database half way through your
process. For performance reasons auto close is not a good idea.
