Creating SQLite trigger in file with delimiter

I have a table and wish to ensure that it only contains one row. I therefore added a couple of triggers, but receive the following errors.

How should the delimiters be used and can I only have one delimiter around both of the triggers?

PS. Not part of the question, but would appreciate a comment whether I should be using BEFORE or AFTER to ensure I only have one row.

  `hash_config` CHAR(32) NOT NULL,
