      • generateHashedFkName

                                           Identifier referencedTableName,
                                           List<Identifier> columnNames)
        If a foreign-key is not explicitly named, this is called to generate a unique hash using the table and column names.

      • hashedName

        public String hashedName​(String s)
        Hash a constraint name using MD5. Convert the MD5 digest to base 35 (full alphanumeric), guaranteeing that the length of the name will always be smaller than the 30 character identifier restriction enforced by a few dialects.
        Parameters:
        s - The name to be hashed.
        Returns:
        String The hashed name.
