MySQL 5.1開始，binlog支持row-based的格式，默認情況下只能看到一些經過base-64編碼的信息，如
DELIMITER /*!*/;

DELIMITER ;
# End of log file
這裡只能看到`test`.`test1`表做了改動，但具體改了什麼，就不知道了，那麼怎樣才能看到到底改了什麼呢？從MySQL 5.1.28開始，mysqlbinlog多了個參數–verbose(或-v)，將改動生成帶注釋的語句，如果使用兩次這個參數(如-v -v)，會生成字段的類型、長度、是否為null等屬性信息。如下：
mysqlbinlog -v -v mysql-bin.001912

這時能看懂了吧？但還有個問題，BINLOG開頭的那些信息還是會顯示出來，很難看，能不能去掉呢？答案是肯定的，加–base64-output=DECODE-ROWS參數。如下
mysqlbinlog -v -v –base64-output=DECODE-ROWS mysql-bin.001912

示例： sudo mysqlbinlog -v -v --base64-output=DECODE-ROWS --start-datetime="2014-08-09 10:42:36" --stop-datetime="2014-08-10 10:42:36" mysql-bin.000005 |grep -A 65 "empolyee"
