Case sensitivity: plain=mixed, delimited=exact No appropriate protocol (protocol is disabled or cipher suites are inappropriate)

回答: "Case sensitivity: plain=mixed, delimited=exact"表示在数据库管理系统中，对于大小写的敏感度有不同的设置。"plain"表示大小写不敏感，"mixed"表示大小写敏感，"delimited"表示使用引号来区分大小写。\[1\] "No appropriate protocol (protocol is disabled or cipher suites are inappropriate)"表示没有适当的协议可用或密码套件不合适，导致连接失败。这可能是由于网络配置问题或安全设置不正确引起的。\[2\]\[3\]
