Changing Database Context
Mar 15, 2001
Hi all,
I have an application that executes the USE command as it's first order of businees with the database. According to the SQL Books On-line, all USE commands will result in the following message being generated:
Error 5701
Severity Level 10
Message Text:
Changed database context to '%.*ls'.
However, my application has never reported this message, execept for at one customer site. I cannot figure out why at this one particular site, the customer is seeing this message each time the application starts. Once they ok the message, everything else with the application is fine, but it is a nuisance for them (gotta love customers!).
Any ideas why this would start happening?

Hi,
I am trying to create a block of sql statements that will read the sysdatabases table, and store the value of the database in a variable.
I want to use a cursor to step through all these databases (excep of course the control databases).
For each of the databases I want to run a backup log followed by dbcc shrinkfile. For dbcc shrinkfile, I need to change the database context.
What I am finding is that I cannot use the variable to hold the database name.
here is the code
-------------------------
SET NOCOUNT ON
DECLARE @db_name varchar(100)
DECLARE @db_filename varchar(100)
DECLARE list_dbs Cursor
FOR select [name] from master..sysdatabases
OPEN list_dbs
FETCH NEXT FROM list_dbs into @db_name
WHILE @@FETCH_STATUS = 0
BEGIN
select name = @db_filename from @db_name..sysfiles
backup log @db_name with no_log
use @db_name
dbcc shrinkfile (@db_filename, 25)
FETCH NEXT FROM list_dbs into @db_name
END
CLOSE list_dbs
DEALLOCATE list_dbs
-----------------------
I get a syntax error where ever the @db_name is used (on the select and on the use).
Any suggestions?
Thanks,
Jim

In reading Has_Perms_By_Name documentation in BOL, it appears that using a three-part name will make no assumption on the database context. However, when I run the code below, I get results that are database context sensitive.
Code Snippet
USE [master];
print has_perms_by_name('master.sys.sysusers', 'object', 'select')
print has_perms_by_name('msdb.sys.sysusers', 'object', 'select')
print has_perms_by_name('AdventureWorks.sys.sysusers', 'object', 'select')
print ''
USE [msdb];
print has_perms_by_name('master.sys.sysusers', 'object', 'select')
print has_perms_by_name('msdb.sys.sysusers', 'object', 'select')
print has_perms_by_name('AdventureWorks.sys.sysusers', 'object', 'select')
print ''
USE [AdventureWorks];
print has_perms_by_name('master.sys.sysusers', 'object', 'select')
print has_perms_by_name('msdb.sys.sysusers', 'object', 'select')
print has_perms_by_name('AdventureWorks.sys.sysusers', 'object', 'select')
The results are:
1
1
1
1
1
1
0
0
0
I created a login called 'temp' and added a user for this login in the AdventureWords database. I then added a securable for sys.sysusers for this user in the Adventureworks database. I then selected the "Deny" checkbox for the Select permission. I connected as temp and ran the T-SQL above.
It appears that the database name is being ignored when included in the name of the securable. What am I missing? Is this a bug?
My version: Standard SQL Server 2005 9.0.3054 on Windows 2003 R2 SP2 (3790).
Thanks,
Randy

I am in a bind here..
I am getting the message (after do any sort of query) Database context changed to <dbname> I am using PHP as the p language.
Does anyone have any clue on why it is doing that..
Recently my host upgraded there PHP to version 4.3.10 and before the upgrade the queries were working fine.
Im on a windows server that runs PHP and im using a MSSQL database.
I've checked the bug reports on PHP and didn't come up with anything as well as googling the error..
IF you have any insite on this problem please let me know.. It may be a stupid error that I am overlooking on my part.
Thanks in advance

I have 30+ databases in sql 2000.
I want to dynalically loop though each of the databases and alter a column named 'EmpName' for all the 'Employees' tables in that database.
Here is my attempt.use Master
go
declare @SQLString Nvarchar(1000)
declare @DBName Nvarchar(100)
declare @SQL2 NVARCHAR(1000)declare @TABLE_NAME NVarchar(100)
DECLARE curDB CURSOR LOCAL FORWARD_ONLY STATIC FOR
SELECT name FROM sysdatabases
OPEN curDB
FETCH NEXT FROM curDB INTO @dbname
While @@FETCH_STATUS=0
Begin
SET @SQL2 = 'USE ' + @DBNAME + ' ALTER TABLE ' + @TABLE_NAME + ' MODIFY EmpName varchar(100)'
from information_schema.tables where table_type = 'BASE TABLE' and table_name like '%Employees%' PRINT @SQL2
EXECUTE SP_EXECUTESQL @SQL2
fetch next from curDB into @DBName
end
Close curDB
End
When i execute the above script in master, it says 'Query executed successfully' but when i see the all the Employees table in each of the database, the required change is not made.
Can anybody explain this or give an alternate solution?

I have database in the database there are a few users that no one is used. When I try to drop thpse users I got next error message:
"The database principal is set as the execution context of one or more procedures, functions, or event notifications and cannot be dropped." (Msg 15136)
Indeed, I think that those users have execute rights on store procedures.
How do I find for wich procedures or other database objects those users have grants?
How do I delete them from database (and maybe from logins of the server)?
How can I see what grants a user has?
How can I see what grants does STP has?

I know sysprocesses has the information, but I can't seem to find how this is done using the dmv's. sessions doesn have a db context, and requests is only active while activity is occurring.
Thanks!

Hi,
I have a MSSQL database running in a Microsoft cluster. I was working on troubleshooting for another SAP problem when they suggested I change the setting using hte SQL Server Client Network Utility to 'named pipes' from 'tcp/ip'. Every since, despite changing it back I'm unable to start the database in the cluster.
I'm kind of a newbie at this so I'd really appreciate any help in getting this database up and running.
Here is the error message from the event log:
sqsrvres] checkODBCConnectError: sqlstate = HY000; native error = 0; message = [Microsoft][ODBC SQL Server Driver]Cannot generate SSPI context

I have a login that is mapped to a Windows sysadmin account. I used it to login to Sql Server 2005. I then created a database called Freedom. I then added a Windows login and user called FreedomAdmin, with Freedom set as the default database. When I login in to Windows using FreedomAdmin and then try to login in to Sql Server 2005, I get the following error:
The server principal "FREEDOM1FreedomAdmin" is unable to access the database "master" under the current security context.
If the default database for FreedomAdmin is Freedom (and it is - I checked from my sysadmin login account), why can't I login. Must I give FreedomAdmin permissions to master?

SQL2005 on winserver 2003. I have a view in Xdb that accesses tables in 2 different databases (Xdb and Ydb) on the same server. I have mixed mode security. I have a SQL user (XYuser) that has read access to all tables and views on both databases, yet when I try to access the view using a C# windows application I get the following error:
The server principal "XYuser" is not able to access the database "Ydb" under the current security context
This same scenario works under SQL 2000. I looked through the postings and tried to set TRUSTWORTHY ON on both databases but that didn't help. I can access any other views or tables on the SQL 2005 server, just not the one that joins the tables cross databases. Any help is much appreciated... john

Hi guys. I created a database "MyDatabase" using an AD Account "user01" which is a member of a domain group "GroupA". I have created a login in my SQL Server 2005 for this AD group. I have also added the said login as a user of my database. I created other AD users and put them in the same group. When I try to access the database using the other users, I get this message
The server principal "MyDomainuser02" is not able to access the database "MyDatabase" under the current security context.
This KB tells me that my situation is triggered by the first case in which the owner of the database is windows authenticated. I have already set the database to be TRUSTWORTHY. I haven't tried CERTIFICATES though. I believe I haven't done anything complex to warrant this solution.
I'm really lost with the myriads of principals and securables that SQL2005 has. All I want is just to execute a certain set of stored procedures. I can't do this because I can't even execute "USE MyDatabase". What are the permissions I need to give to "GroupA" ?

I have come across a problem having developed my DTS packages on one database (dev server) which has a different name to the database on the Test/Live servers. I had planned for this in that I was changing the server and database source before executing the package. When I tested this it turns out that the file import transformation that references the table to import into specifies the whole database.owner.table name and the database portion has not changed and therefore the package fails. I've dumped the package using the dts utility to view the vb script and have found the property DestinationObjectName (part of the custom task object for the relevant step...) which looks like the one to change but is this really what has to be done?
regards
Ken

Hi.
I thought I had this solved but after running aspnet_regiis again
I am having the same problem.
I can't log onto my sql server because the default DB is master.
The following command using sqlcmd gives me the master db:
Code:
SELECT *
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'
GO
So, to try to fix this i ran:
Code:
EXEC sp_defaultdb 'sa', 'my_default_db'
GO
and no luck. I went over to the DB server and checked
the permissions under SERVER/SQLEXPRESS > SECURITY > LOGINS. All except NTAuthority and Administrators have
my intended DB as the default (including ASPNET).
This is frustrating because I know I have figured it out
before but I can't remember what I did. Help appreciated.
Thanks.

Hi there,
We currently install some of client's databases on SQL Server 2000 with the collation set to Latin1_General_BIN but we have one client that was installed and now running on SQL_Latin1_General_CP1_CI_AS and I was wondering if we can change the collation on the database to Latin1_General_BIN?
Would this have any adverse affects on the DB or the data within it? Our strings are nvarchar.
Thanks for your help

that sounds obvious but I'm stuck...
I have an ASP.net application which someone else started and I continue.
on the SQL server there was a user X which was used to access the database from the ASP website.
I accidently changed the password in the SQL server and now I cant restore the prior settings
(trying to reset password to blank or embedding the username and password in the connection string didnt work).
it stops on "connection.open" with - "SQLException Login failed for user 'X'"
any ideas why that happens and how I can fix it?
thanks

Hey guys,
I uploaded my website from VWD Express to ipower. My database did not work, which I have learned upon some research should have not been a shock to me, but most definetely was. When I contacted tech support they told my that my web.config files were pointing to my local paths. That I should change them and I should be fine. Elsewhere, in the knowledge base I found the strConnect that I am under the impression I need to use.
strConnect = "Provider=SQLOLEDB; Server=SQL-A1; UID=account_username; PWD=account_password; Database=user_db_name" oSQLServer.Connect strServer,strLogin,strPwd
The problem is, I'm a complete newbie, learning as I go and I can't find anything on where or how I insert this into my web.config to correct my paths. IPower will not help with coding. I know my current connection string is in web.config in the appsettings, that's about as far as my knowledge goes.
So, could anyone show me how I go about putting this into my web.config? Examples are very helpful :]
On a side note, I've been reading that this is a common problem among newbies like myself. So, is changing these files actually going to work, or am I wasting my time? Also, before I get knee-deep into it, is the database-publishing kit put out by MS the way to go here?
Thanks for any and all replies, you guys are always awesome.

I am having a hard time finding materials on this subject. I am guessing I am using the wrong keywords to search. Basically, I want to be able to modify database tables through a web form. They can add columns and delete columns through the form. I would just want to default the type of column and the length. I am sure it has been done, I was just wondering if anyone had some resources they could throw my way. I would appreciate it. Thanks.

If you enter "Create Database test", the database files (mdf file & log file) are created, by default, in:-
C:Program FilesMicrosoft SQL ServerMSSQLData
I want to change that to:-
D:Database Files
I sucessfully moved the model database to this location (using the instructions in BOL) assuming that all new databases would now get created in the same location, but they don't. They still get created in:
C:Program FilesMicrosoft SQL ServerMSSQLData
So how do I change the default?
(It's not satisfactory to have to move each database after it's created)
Thanks, Andy Abel

I currently have a server with the collation set to SQL_Latin1_General_CP1_CI_AS.
However, some of the databases within the server are set to Latin1_General_BIN, probably because they were restored from another server some time ago. Also, even within the databases that have Latin1_General_BIN, some of the columns are set to SQL_Latin1_General_CP1_CI_AS, very confusing to say the least.
What i would like to do is change the database collation settings for these databases to match the server setting. I would also like to change all of the tables within these databases to have the columns also set to the server collation settings.
I'm looking for the steps that i would need to take to make sure i don't mess anything up as these databases have there own sets of views and sp's that run each day.
