 The initialization of the ODBC database type is achieved by calling sql:initialize-database-type  on the database type :odbc . In an application, this step should be done at runtime.
The following functions and variables are relevant to initialization:
 Specifies the default type of database. Currently only ODBC is supported, and therefore this should be set to :odbc .
 Contains a list of database types which have been initialized by calls to initialize-database-type .
 sql:initialize-database-type &key  database-type Initializes a database type according to the value of  database-type . Adds  database-type to the list of initialized types.
A sample code sequence for initializing SQL to work with an ODBC database, using the above functions and variables, is as follows:
(require "odbc")
(setf sql:*default-database-type* :odbc)
(sql:initialize-database-type)
