我的数据库中有逗号分隔的列。该列称为“访问”,它处理诸如1,2,3,4,5,6,7之类的数字。我需要比较会话值的要求称为kt_department,其中之一是逗号分隔的值,例如kt_department的值是4,那么其余数据将显示在页面中。但是,如果不是,它将继续到下一行,但是如果再次找不到,则应该继续到下一行,直到找到用逗号分隔的值为止。但是,如果他们什么也没找到,则会出现类似“无可用记录”的消息。并且发现的记录也应该计数。

感谢大伙们。请帮我。谢谢!

最佳答案

要为您的问题提供实际答案(请注意Sharma):

从问题中摆脱掉用户名和密码进入数据库。即使它是本地主机,也伤害了我的眼睛。

回答您的问题。我会不建议您使用列accesskt_dept或您想调用的列创建第二个表。这样,您可以将访问整数与kt_dept连接-意味着一个kt_dept具有零到多个access

有了这种实现,您只需要运行如下查询
    SELECT kt_dept从newTable中访问='{$ access}'
并检查是否返回任何行。
