     # File lib/sequel/sql.rb, line 208
208:       def cast_numeric(sql_type = nil)
209:         cast(sql_type || Integer).sql_number
210:       end
          Cast the reciever to the given SQL type (or the database‘s default string type if none given), and return the result as a StringExpression, so you can use + directly on the result for SQL string concatenation.

215:       def cast_string(sql_type = nil)
216:         cast(sql_type || String).sql_string
