我在 Ruby 中使用以下查询：
mcuglist = Balsiebeltogenevaprodmapping.find_by_sql ["select * from master_cug_list where customer_ref = ? and product_seq = ? and end_date = ? and line_seq is null order by directory_number",bseq_11.customer_ref,bseq_11.product_seq,(accdtlmap.start_dat.to_date + 9).strftime('%Y-%m-%d')]
它给了我标题中给出的错误：(full) year must be between -4713 and +9999, and not be 0。
关于如何传递date给的任何想法find_by_sql query？
