Field reference_id in table _comments

Hi together,

i am facing a (i hope) simple problem:
Fehlende optionale Spalte “reference_id” in der Tabelle “DBtj3_comments”.
in english :
Missing optional column “reference_id” in table “DBtj3_comments”.

i cannot access the server via ssh (due to the provider) so i cannot run the command occ db:add-missing-columns

Can anybody tell me what kind of field (int, BIGINT, charvalue…) “reference_id” has to be ?
Than i can add it manually via PhPMyAdmin.

Thanky for the help !
