Because there are a wide array of different SQL database systems from a variety of different vendors it is not feasible to give detailed instructions in this chapter. See your SQL database administrator if you have any questions.
It is worth noting, however, that one of the most common problems that developers experience is not being able to access a SQL database because security and permissions have not been set up correctly.
If you receive unexplained errors at runtime when you attempt to access an SQL database, it is a good idea to check the user id and password you are using. Ensure that they have the appropriate permissions set up in the SQL database system to allow you access to the database and tables you are using.
