查询给出零输出

Question

我正在尝试使用下拉列表过滤结果并将其显示在表格中。从理论上讲，我的查询应该获取所有请求的数据，但我得到零结果。也许我看这个太久了。我做错了什么。

SELECT ac.route, ac.page_number, ac.link_number, ac.address, di.type, 
pa.file_code, pb.member_id 

FROM digital di, ips_trans ip, members pa, 
files ac, publication pb 

WHERE Date_Format(di.date,'%Y-%m-%d') = Date_Format(ip.roll_date,'%Y-%m-%d') 
      AND Date_Format(di.date,'%Y-%m-%d') = Date_Format(pa.date,'%Y-%m-%d') 
      AND di.payment = pa.paymentnow 
      AND ac.page_number = ip.code_number
      AND ac.phone_number = pb.cell_number
