 SQL-Error in Query All parts of a PRIMARY KEY must be NOT NULL; if you need NULL in a key, use UNIQUE instead As far as I know is this error,only if mysql is 5.7 or higher 
 Do I have to replace all PRIMARY KEY text into UNIQUE in all files?
 or change defining o not null?I wonder if this script is outdated? 
 I use hotelcommerce 1.3.2Found the solution here: 
 https://www.prestasoo.com/blog/fixing-the-sql-error-on-prestashop-installation.htmlYes, Version 1.3.2 is outdated and needs this fix.
