I want to grant TRIGGERS, FUNCTIONS and PROCEDURES to a role. I have the code to do it with procedure but with triggers and functions it not work.
create role Level1;
grant execute any trigger to Level1;
grant execute any procedure to Level1;
User owns tables, functions and procedures. That user created a role and wanted to grant execute on various objects to the role.
for triggers, it doesn't make sense - they fire upon certain action on the table they are created on. Therefore, you'd grant privileges on the table, not on the trigger
for functions and procedures, you'd grant execute privilege on exact functions and procedures (not for all of them in a single statement), e.g.
grant execute on p_insert_student to level1;
grant execute on f_average_marks to level1;
What you posted (grant execute any procedure) is a system privilege; that's kind of dangerous; are you sure you want to let level1 execute absolutely any procedure within the database?
Also, there's no separate grant for functions; in this context, they are considered to be procedures so execute any procedure affects functions as well.

Is there any syntax available in the grant command that would allow something equivalent to
Use [SomeOtherDatabase]
grant execute to [domain\UserLogin]
What I'm hoping to do might look something like this:
grant execute On [SomeOtherDatabase] to [domain\UserLogin]
Which of course does not work...
NOTE:
I am aware of the syntax
grant execute on [Something] to [domain\UserLogin],
but in this form, [something] must be an individual database object, (procedure/function), as in
grant execute on [database.Schema.Procedure] to [domain\UserLogin],
not all objects in the database. you can't do
grant execute on [Database] to [domain\UserLogin]
and apply the grant for every object in the database.
I want to set a readony permission to a database user.
This user should have permission to execute stored procedures
But this user should not have permission to update or inser or alter anything in database through these stored procedures or through any methord
can anyone help please
Simply don't grant permission on the stored procs that change data.
Otherwise, you could use triggers on the tables to check, but that's a bit silly compared to using permissions correctly
Note: ownership chaining means that permissions on tables won't be checked, even DENY, so this won't work.
Yes. Set the EXECUTE permission for that user, then they'll only be able to execute the Stored Procedures in your database.
GRANT EXECUTE ON dbo.storedprocedurename TO SQLUSERNAME;
You'll need to set the permissions on a procedure by procedure basis. Give them permission to stored procedures that select, and don't give them permission to the stored procedures that do updates or inserts.The best way is to setup roles, and add the users to the roles.
This is pretty flexible and you can use it to restrict exactly what uses can do. For example, it may actually be okay for them to update a table as long as they do it through a certain stored procedure. To do this you can deny them all permission to that table, but grant them permission to execute the stored proc.
give execute permission on the proc and make sure the user doesn't have write access to the tables used by the proc. Check if he is not member of the db_datawriter roled.
If you want to be 100% sure, add the user to the db_denydatawriter role
Does the following command effectively give the user, "MyUser," permission to execute ALL stored procedures in the database?
GRANT EXECUTE TO [MyDomain\MyUser]
SQL Server 2008 and Above:
/* CREATE A NEW ROLE */
CREATE ROLE db_executor
/* GRANT EXECUTE TO THE ROLE */
GRANT EXECUTE TO db_executor
For just a user (not a role):
USE [DBName]
GO
GRANT EXECUTE TO [user]
SQL Server 2005 introduced the ability to grant database execute permissions to a database principle, as you've described:
GRANT EXECUTE TO [MyDomain\MyUser]
That will grant permission at the database scope, which implicitly includes all stored procedures in all schemas. This means that you don't have to explicitly grant permissions per stored procedure.
You can also restrict by granting schema execute permissions if you want to be more granular:
GRANT EXECUTE ON SCHEMA ::dbo TO [MyDomain\MyUser]
In addition to the answers above, I'd like to add:
You might want to grant this to a role instead, and then assign the role to the user(s).
Suppose you have created a role myAppRights via
CREATE ROLE [myAppRights]
then you can give execute rights via
GRANT EXECUTE TO [myAppRights]
to that role.
Or, if you want to do it on schema level:
GRANT EXECUTE ON SCHEMA ::dbo TO [myAppRights]
also works (in this example, the role myAppRights will have execute rights on all elements of schema dbo afterwards).
This way, you only have to do it once and can assign/revoke all related application rights easily to/from a user if you need to change that later on - especially useful if you want to create more complex access profiles.
Note: If you grant a role to a schema, that affects also elements you will have created later - this might be beneficial or not depending on the design you intended, so keep that in mind.
I wish to grant a stored procedure read access to a table in SQL Server 2008 R2
I will then grant a user access only to the stored procedure, not to the table itself.
How do I do this?
Grant EXEC access to the single stored procedure and no permissions to the table.
Grant EXECUTE On [SpName] To [Principal]
There is no such concept as a read permissions to a table for a stored procedure. Stored procedure permissions are separate from other objects. If a user has permission to run a stored procedure, they can run it no matter what it does, even if they don't have permission to the underlying objects.
The following article is a very detailed look at several different methods for granting permissions using stored procedures. It's definitely worth a read.
http://www.sommarskog.se/grantperm.html
Most of the time, ownership chaining will take care of permissions problems. As long as the stored procedure and the underlying table have the same owner, the user only needs permission to EXECUTE the stored procedure.
In a comment to another answer, you mention that the stored procedure is in a different database from the table. You might look at module signing as a method for allowing access only through the stored procedure. Another alternative, if possible, is to create the stored procedure in the same database as the table, then grant access to users in the other database. That way, ownership chaining will take effect.
I am looking for a way to have a database user only have rights to execute stored procedures and functions. This needs to be a dynamic setting so that every time i add a stored procedure or function they have rights to it.
Constraints
I cannot change the names of the schema or stored prcedures or functions.
In SQL Server 2005 and newer, you can create a new database role
CREATE ROLE db_executor
and then grant that role the permission to execute - without specifying anything.
GRANT EXECUTE TO db_executor
This role can now execute all stored procedures and function in the database - and it will be able to execute any future stored procedures you add to the database, too!
So now just add this role to your user and you're done:
exec sp_addrolemember #rolename = 'db_executor', #membername = 'your-user-name-here'
PS: of course, you could also grant this permission to just a single user:
GRANT EXECUTE TO your-user-name
This makes management a nightmare, however - so I wouldn't go down that path..
