SHOW BINLOG EVENTS
Synopsis
SHOW BINLOG EVENTS [IN 'log_filename'] [FROMposition] [LIMIT [offset,]count]
This statement displays the events in a binary log file. Use
the IN clause to specify a particular log file. If the
IN clause is omitted, the current file is used. To
obtain a list of binary log files, use the SHOW MASTER LOGS statement. Here is an example of how you can
use this statement and typical results:
SHOW BINLOG EVENTS IN 'log-bin.000161'\G

with a value of 4. In a large log file, that number might be in the
thousands. The results displayed could be focused only on rows
starting from a particular position in the log with the
FROM clause. You can limit the number of rows of
events displayed with the LIMIT clause. In the
LIMIT clause, you can also set the starting point of the output based on the number of rows in the results set and limit them to a certain number of rows. Here is an example of both of ...
