/*CREATE DATABASE "intl_emp.fdb" DEFAULT CHARACTER SET ISO8859_1; */

/**  18-July-1994:  Clare Taylor:  Created this file, intlddl.sql, from the
 **                 empddl.sql file.  It has been modified as shown below
 **                 to create an international version of the example database.
 **
 **  Create a sample international employee database (intlemp.fdb).
 **
 **  This database keeps track of employees, departments, projects, and sales
 **  for a small company and uses ISO8859_1 for the DEFAULT CHARACTER SET.
 **
 **  International changes to this file:
 **
 **  - DOMAIN lastname:         increased field size to 25 from 20.
 **  - CUSTOMER.CUSTOMER field: increased the field size to 40. required
 **                             for long German and French company names.
 **  - CUSTOMER.ADDRESS1 and 2: increased from 30 to 40 chars.
 **  - Added 4 sorting stored procedures--may be changed in next build.
