    这是一个创建于 2316 天前的主题，其中的信息可能已经有所发展或是发生改变。

    问题一：

     /usr/local/bin/mysqlbinlog  --start-datetime="2018-08-24 16:33:57" --stop-datetime="2018-08-24 16:34:36" mysql-bin.000037 > abc.sql
    mysql-bin.000037文件不带时间直接使用mysqlbinlog导出，数据为
    /*!50530 SET @@SESSION.PSEUDO_SLAVE_MODE=1*/;
/*!50003 SET @OLD_COMPLETION_TYPE=@@COMPLETION_TYPE,COMPLETION_TYPE=0*/;

    那么问题来了

    开始时间为2018-08-24 16:33:57,那abc.sql文件中为啥有180824 16:24:46这个时间点的

    结束时间为2018-08-24 16:34:36,那abc.sql文件中为啥没有180824 16:34:36这个时间点的

    问题二

    mac os下关于date时间函数问题 我写了一个脚本，用作，输入时间点进行binlog回滚点，时间点使用参数形式传进去后，是一个字符串的形式，我想把这个字符串转为时间类型，不知要如何转，试了几种方式，不得其法。

    我的大概脚本内容

    incre_recov(){
    echo '增量回滚数据，需要三个参数，binlog 文件，start-datetime，stop-datetime'
    echo 'start-datetime 格式为："2018-08-23 14:01:00"，此处为双引号'
    echo $#
    if [ $# != 6 ];then
        echo "参数数量不对"
    else
        echo '$1' + 'is' + $1
        echo '$2' + 'is' + "$2"
        echo '$3' + 'is' + "$3"
        echo '$4' + 'is' + "$4"
        echo '$5' + 'is' + "$5"
        echo '$6' + 'is' + "$6"
      
        start_time=`date -j -f "%Y-%m-%d %H:%M:%S" "$3 $4" "+%s"`
        end_time=`date -j -f "%Y-%m-%d %H:%M:%S" "$5 $6" "+%s"`
        ${MysqlPath}/mysqlbinlog  --start-datetime="$start_time" --stop-datetime=="$end_time"  $2 > abc.sql
        echo "${MysqlPath}/mysqlbinlog  --start-datetime="$start_time" --stop-datetime="$end_time"  $2 > abc.sql"
       
    fi
    
case "$1" in
    incre_recov)
    incre_recov $*
    ;;
    *)
	echo "$0 [incre_recov]"


	exit 0
esac
}

    脚本运行结果

    sos:work_shell apple$ sh MysqlFullBack.sh incre_recov /Users/apple/work_shell/incre_backup/20180824/mysql-bin.000037 "2018-08-24 16:33:57" "2018-08-24 16:34:36"
增量回滚数据，需要三个参数，binlog 文件全路径，start-datetime，stop-datetime
start-datetime 格式为："2018-08-23 14:01:00"，此处为双引号
6
$1 + is + incre_recov
$2 + is + /Users/apple/work_shell/incre_backup/20180824/mysql-bin.000037
$3 + is + 2018-08-24
$4 + is + 16:33:57
$5 + is + 2018-08-24
$6 + is + 16:34:36
ERROR: Incorrect date and time argument: 1535099637
/usr/local/bin/mysqlbinlog  --start-datetime=1535099637 --stop-datetime=1535099676  /Users/apple/work_shell/incre_backup/20180824/mysql-bin.000037 > abc.sql

    按照mysqlbin --help这里--start-datetime和--stop-datetime=，格式要为DATETIME and TIMESTAMP才行

    那么我这个传进去的起止时间要怎么处理？

    是因为没有可用的有效备份嘛？才搞这么麻烦？

    @likuku #1 不是，只是用此列个自己疑惑的案例，希望 v2 这里能解惑一下。
