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I wonder if this script is outdated?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 1.3.2
Found the solution here:
Yes, Version 1.3.2 is outdated and needs this fix.
