What privileges are needed to create\delete tables on a Microsoft SQL Server? Is dbowner ok?

I am not so into SQL Server and I have the following doubt: I have to require the creation of an user that can work on some databases. This user have to create\delete table, insert\delete records in these tables.

What type of permission have to be set for this user on these databases? Is dbowner ok to perform these operations? (in particular is very important that this user can create\delete tables) or am I missing something?

Solution

  • Just to understand first the benefits of using roles :

    • Roles are a part of the tiered security model:
    • Login security—Connecting to the server
    • Database security—Getting access to the database
    • Database objects—Getting access to individual database objects and data**

    Predefined database roles You may need to create your own, but you have access to several predefined database roles:

    • db_owner: Members have full access.
    • db_accessadmin: Members can manage Windows groups and SQL Server logins.
    • db_datareader: Members can read all data.
    • db_datawriter: Members can add, delete, or modify data in the tables.
    • db_ddladmin: allows a user to create, drop, or modify any objects within a database, regardless of who owns.
    • db_securityadmin: Members can modify role membership and manage permissions.
    • db_bckupoperator: Members can back up the database.
    • db_denydatareader: Members can’t view data within the database.
    • db_denydatawriter: Members can’t change or delete data in tables or views.

    Fixed roles : The fixed server roles are applied serverwide, and there are several predefined server roles:

    • SysAdmin: Any member can perform any action on the server.
    • ServerAdmin: Any member can set configuration options on the server.
    • SetupAdmin: Any member can manage linked servers and SQL Server startup options and tasks.
    • Security Admin: Any member can manage server security.
    • ProcessAdmin: Any member can kill processes running on SQL Server.
    • DbCreator: Any member can create, alter, drop, and restore databases.
    • DiskAdmin: Any member can manage SQL Server disk files.
    • BulkAdmin: Any member can run the bulk insert command.
