我有下表：

我正在尝试插入一行：
INSERT INTO logs (ID, ReceivedAt, DeviceReportedTime, Facility,
Priority, FromHost, Message, InfoUnitID, SysLogTag, CustomerID,
NTSeverity, Importance, EventSource, EventUser, EventCategory,
EventID, EventBinaryData, MaxAvailable, CurrUsage, MinUsage,
MaxUsage, EventLogType, GenericFileName, SystemID)
VALUES ('34823017',
'2015-06-26T15:06:02+03:00',
'2015-06-26T15:06:38+03:00',
'22',
'6',
'po-sv-bus-01v',
'type=SYSCALL msg=audit(1435320388.132:831638): arch=c000003e syscall=4 success=yes exit=0 a0=7f4bc8616ca0 a1=7f4bd1c10c00 a2=7f4bd1c10c00 a3=0 items=1 ppid=1 pid=3489 auid=286786658 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 ses=204 tty=(none) comm="rsyslogd" exe="/sbin/rsyslogd" subj=unconfined_u:system_r:syslogd_t:s0 key="power-abuse"',
'1',
'audit: ',
'',

'',
'',
'',
'',

'',
'',

'');
我得到了错误：
错误 1062 (23000)：键 'PRIMARY' 的重复条目 '34823017'
虽然没有重复条目：
mysql> select * from logs where ID = '34823017';
Empty set (0.00 sec)
有人可以帮我吗？
【问题讨论】：
-
你是否在没有单引号的情况下运行它，因为 select * from logs where ID = 34823017;
-
这种情况下重启mysql服务再检查一遍
-
你有一个auto_increment ID，为什么要手动设置ID
-
如果您的索引损坏，MyISAM 表可能会出现此类问题。 grokbase.com/t/mysql/mysql/114w8qh68y/…
-
正如@PaulF 所说，您的 ID 字段不仅是您的主键，而且您将其设置为自动增量，这意味着您不应该在该字段中插入值或修改其中的值场地。从您的查询中删除它应该可以解决您的问题。
