when creating the /*prefix*/code_authors table, I'm the following error message

CREATE TABLE gdncode_authors (

• Repository ID ca_repo_id int not null,
• "Native" author name in the repo ca_author varchar(255) binary,
• Local wiki username, if any, to tie the edits to instead
• Using a username instead of ID so we don't have to worry
• about SUL accounts which haven't been copied over. ca_user_text varchar(255) binary,
  
  primary key (ca_repo_id, ca_author),
• Note that multiple authors on the same repo may point to
• a single local user in some cases... unique key (ca_user_text, ca_repo_id, ca_author)
