Init

First we need to open a connection to a database by providing the c-treeACE Database Engine with a user name, password and the database name.

Below is the code for Initialize():

/*

 * Initialize()

 *

 * Perform the minimum requirement of logging onto the c-tree Server

 */

void Initialize(void)

{

   os_printf(DH_STRING_LITERAL("INIT\n"));

   os_setenv (DH_STRING_LITERAL("DH_USER"), DH_STRING_LITERAL("ADMIN"));

   os_setenv (DH_STRING_LITERAL("DH_PASSWD"), DH_STRING_LITERAL("ADMIN"));

   os_setenv (DH_STRING_LITERAL("DB_NAME"), DH_STRING_LITERAL("ctreeSQL"));

   EXEC SQL CONNECT TO DEFAULT ;

   if (sqlca.sqlcode)

      Handle_Error(sqlca.sqlcode, sqlca.sqlerrm);

}
