Question

尝试使用每个舞者更新oracle数据库上的时间戳时，我收到以下错误。

ORA-01858: a non-numeric character was found where a numeric was expected.

代码：

   my $fmt = 'YYYY-MM-DD HH24:MI:SS:FF3';
   database->do("alter session set nls_timestamp_format = '$fmt'");


    my $time_start =params->{'start1'};#2014-04-29 10:21:42:037

    my $time_stop = params->{'stop1'};  #2014-04-29 10:42:08:355
    my $id = params->{'id'};

    my $timestart ="TO_TIMESTAMP('$time_start','YYYY-MM-DD HH24:MI:SS:FF3')";
    my $timestop ="TO_TIMESTAMP('$time_stop','YYYY-MM-DD HH24:MI:SS:FF3')";
    database->quick_update($table, {ID => $id}, {SBYS_START_TIME => $timestart, SBYS_STOP_TIME =>$timestop});

我在这里看到了两种可能性：

您的输入值与您评论的内容不匹配（例如，该停止时间缺少0，可能是秒数）

要检查这一点，请添加一个快速调试行：

my $time_start = params->{'start1'};
debug $time_start;
my $time_stop = params->{'stop1'};
debug $time_stop;

您的代码将$ time_start作为文字sting传递给数据库。

尝试上旧学校。：

my $timestart ="TO_TIMESTAMP('" . $time_start . "','YYYY-MM-DD HH24:MI:SS:FF3')";
my $timestop ="TO_TIMESTAMP('" . $time_stop . "','YYYY-MM-DD HH24:MI:SS:FF3')";

这将消除这种可能性。
