The initialization of the chosen database type is achieved by calling
The following functions and variables are relevant to initialization:
*default-database-type* specifies the default type of database. The possible values are shown in the database-type column of Supported databases.
The function initialize-database-type initializes a database type according to the value of its database-type argument, which defaults to the value of *default-database-type*.
A sample code sequence for initializing Common SQL to work with an ODBC database, using the above functions and variables, is as follows:
(setf *default-database-type* :odbc)
You can find which database types have been initialized by the value of the variable *initialized-database-types*.
