JDBC connection for Sybase with authentication query - sybase

I have a datasource that connects to Sybase database. I need to execute the authentication statement (SET TEMPORARY OPTION CONNECTION_AUTHENTICATION='Company....) after I connect to the database.
Is there any way of executing this statement as part of the validationQuery in the JDBC connection param so that the connection is automatically authenticated?
ANSWER:
I have managed to get answer for this !!!
This can be done by setting it in the connection url with the below parameter
SQLINITSTRING=SET TEMPORARY OPTION CONNECTION_AUTHENTICATION='Company.......

Maybe Sybase login triggers are something you could use. Here the steps i would do:
Create a stored procedure which is executing your statement
Create a new dedicated database login
Assigne the login trigger to the newly created stored procedure.
More information about login triggers you find here:

Unable to get stored procedure names in the dropdown using SQL authentication in azure logic app

I am not able to retrieve stored procedure names in the dropdown if I use SQL Server authentication.
I can view/execute stored procedure from SSMS using the SQL Server account credentials. Login user has view/execute access for stored procedures.
I see the error shown here when I try to execute stored procedure step from a logic app :
Could not retrieve values. BadGateway. Client request id:
Any help is appreciated!
According to some test, the latest permission will take some time to take effect(about 5-10 minutes). After a few minutes, you can go to the API connection and click "Refresh" button. Then go to logic app click "Change connection" and choose another API connection and then click "Change connection" again to choose back to the API connection. Then it will take effect. I test it with allow/not allow ip to connect to sql server.

Extracting UID from ODBC Connection in MS Access

I have a MS Access front end with tables linked to SQL Server. I used a file DSN to link tables, and upon opening Access database the user has to enter SQL server userID and password.
Is there a way to extract that userID (not the password) from the established ODBC connection, for example to use it for display and audit purposes?
Yes, you can create a Pass-Through query in Access with just the statement...
SELECT CURRENT_USER
...then in the Property Sheet for that query click the ellipsis button beside ODBC Connect Str and select your File DSN. (When asked if you want to save the password in the connection string, say "No".)
Then save the Pass-Through query (I called mine "getCurrentSqlUser") and run it to get the name of the current user on the SQL server.
(Note: While testing this I logged in as sa and found that the query returned dbo. I think that's because I was logged in as a member of the sysadmin Server Role.)

can't change the password for a user

I have downloaded database and attached it to my local sql server, however I can't seem to change the password of one the existing user's on the db.
Using the following command:
ALTER LOGIN [NotificationsUser] WITH PASSWORD = 'password';
I get the error:
Msg 15151, Level 16, State 1, Line 1
Cannot alter the login
'NotificationsUser', because it does
not exist or you do not have
permission.
Is this possible?, what access permissions do I need to change user permissions anyway ?
If you've attached this database to your local SQL server then you'll need to do a couple of things:
If you haven't already done so, create user logins on your SQL server to match the ones that exist in the attached database. It's simpler to do this before attaching the database. But it can be done after the DB has been attached.
Because the SID's of the users in the newly attached database won't be the same as the newly created logins you'll need to resolve this using the sp_change_users_login stored procedure. The database user's are in effect orphaned.
For example if you have:
SQL Login: bob Attached database user: bob
Open a new query in SQL Management Studio for the attached database then run:
sp_change_users_login #action='report'
If you have "orphaned" users in your database then you'll see a result set that looks like:
UserName UserSID
bob 0x57F6DFA5D5D7374A97769856E7CB5610
To reconnect this user to a SQL login execute:
sp_change_users_login #action='update_one',
#loginname='bob',
#usernamepattern='bob'
I think you're confusing a database user with a server login.
Your database may have a user in it called NotificationUser but this needs to be associated with a server login, which is the object you're trying to alter with the script. A database restore from a different server won't have created this server login so there's a good chance it doesn't exist on your server. More info here

How to pass out-of-band (current User Id) data to SQL Server 2008

We have a web application that uses forms authentication to authenticate a user based on a user table in the database. (I.e. no active directory or SQL server user accounts are involved here). The web application accesses the SQL server using a service account. However, for auditing, authorization and other purposes, our stored procedures need to know for which user any given operation is being executed.
In a previous life, I worked with a similar situation using an Oracle database. In this scenario, every time we opened a connection, we first called an Oracle build in procedure to set a connection scoped context variable. This variable contained the user id for the user that would be using the connection. Then all stored procedures that needed to know the current user would check the context variable.
Conceptually this worked a lot like pushing user information onto the CallContext before making a remote call.
My question is, is there any similar mechanism in Microsoft SQL server?
Obvioulsy, if I must, I can pass the UserId as an argument to every single stored procedure, but that is exactly what I am trying to avoid.
Use SET CONTEXT_INFO and CONTEXT_INFO(). See Using Session Context Information.
What you can do is create users within the database (without Server logins) and give them appropriate permissions. After that, what you do is an "execute as" statement and then the user context for your database calls will be as if the user called it. Example:
EXECUTE AS USER = 'user2';
EXECUTE usp_insert_stuff #params;
REVERT;
Downside: you have to set up SQL security and manage users
Upside: Users cannot connect directly to SQL Server and you get auditing.

Cannot Find Stored Procedure Error

I recently did an import of database from a sql server 2000 database to a sql server 2005 database. I've gone through and setup what I thought were the same login credentials and owner permissions that I had previously setup in my old database.
All of the code base I'm working has stored procedures listed simply by stored procedure name.
In order to make sure I have the proper logins created, I am logging into the SQL Server Management studio with the connection information my application is using (i.e. using the username "licensemgr" and it's associated password). I can see all the tables, stored procedures, etc... in my database when I log in with combination. When I try to run a stored procedure, Sql Server Management Studio uses the following syntax to execute it:
EXEC: #return_value = [licensemgr].[Stored_Procedure_Name]
and it executes without error.
If I try to remove the [licensemgr]. from before the [Stored_Procedure_Name], however I get the error "Cannot find stored procedure: Stored_Procedure_Name". This is the same error I get when running my application off this database. I changed one stored procedure call in my application to have "licensemgr." in front of the stored procedure name and that seemed to correct the problem, however, I don't want to do that for each and every stored procedure call in my application. I am therefore wondering what type of setup / permissions type issue I might be missing in my SQL Server instance so that even when I'm logged into the database as licensemgr, I cannot see the stored procedure which is in the schema "licensemgr".
In SQL server 2000 the [licensemgr] referred to the owner of the table. So when you are logged in as [licensemgr] you do not need the prefix.
In SQL Server 2005 this has been changed to the schema, therefore it must be specified. See:
http://msdn.microsoft.com/en-us/library/ms190387.aspx
EDIT
There are two things that you need to watch out for:
If the user is in the sysadmin role, he will always default to the dbo schema, therefore you need to prefix
If your user needs to run code that is in different schemas you will need to prefix
If none of the two above it should work by setting the default schema for the user
When you created your user, did you specify DEFAULT_SCHEMA?
CREATE USER ... WITH DEFAULT_SCHEMA = "licensemgr"
If not, you may need to use ALTER USER to fix this for your user in the new system.
