[TRANSACT]Cant switch from master to another database

Hello,

I encounter a problem with a small portion of sqlcode. I try to go on
database using "use dbname" but i always stay in master. I execute
script with the sa user.

declare @.dbnamesysname
declare @.ret_codeint

DECLARE db_cursor CURSOR FOR
select
name
from
master..sysdatabases
where
name not in ('master', 'model', 'tempdb', 'pubs', 'Northwind')

-- Open cursor
OPEN db_cursor
FETCH NEXT FROM db_cursor INTO @.dbname

WHILE @.@.FETCH_STATUS = 0
BEGIN
execute ('use ' + @.dbname)
execute ('select db_name()')

Thank's for help,
Pierrot.USE is scoped only within the EXEC statement so you'll have to combine
the two:

EXEC ('USE ' + @.dbname+' SELECT DB_NAME()')

If this is for non-production code you might consider using the
following undocumented proc instead of the cursor:

EXEC sp_msforeachdb 'USE ? SELECT DB_NAME()'

This still implements a cursor behind the scenes but keeps some of the
complexity out of your own code.

AFAIK, executing just open up a session to excute something, when executing
the next statement you are in another Session, try to combine these two
together with
EXECUTE ('Use Northwind;Select DB_NAME()')

|||As Jens indicates each EXECUTE is its own session, so to do this in an
execute you must place all of the statements together...
Depending on what you are trying to do you could also use the 3part name
Declare @.str varchar(100)
Select @.str = 'select * from ' + @.dbname + '.dbo.thetable'
execute (@.str)
for System Sps you could also do
Declare @.str varchar(100)
Select @.str = 'Execute ' + @.dbname + '.dbo.sp_spaceused'
execute (@.str)
If you wish to do something for each database try sp_foreachdatabase ( I
think is the name of the sp.)
