The initialization of Common SQL involves three stages. Firstly the SQL interface loaded. Next, the database type (actually class) to be used is initialized. Finally, Common SQL is used to connect to a database. These stages are explained in more detail in this section.
The Lisp symbols introduced in this chapter are exported from the
sql
package. Application packages requiring convenient access to these facilities should therefore use the
sql
package.
The examples in this chapter assume that the
sql
package is visible.
