问题
I use mysqldump to create a dump of my data table. The only problem is, that mysql stores a null value as /N and if I want to import the created CSV file into HANA, /N is not known as null but as varchar.
Is there a way to skip the null values during dumping or can I just replace /N with a blank?

As far as I know,there are no options for handling the output of NULLs. You could try to replace NULLs with empty in your table:
UPDATE `tablename` SET columnname= '' where columnname is null
