Determining what query was called
You could enable binary logging. If you have not done so already.
To find out if binary logging is enabled, run this:
SHOW MASTER STATUS;

If you get back, Empty set, it is not enabled.
If you have not, please add this to my.cnf under the [mysqld] section
[mysqld]
log-bin = mysql-bin

Then, restart mysql.
From that point forward, you could look for all changes within timeframes.
For example, suppose you run SHOW BINARY LOGS; and get something like this:
mysql&gt; show binary logs;
+----------------+------------+
| Log_name       | File_size  |
+----------------+------------+
| bin-log.000645 |    5933323 |
| bin-log.000646 | 1073745654 |
| bin-log.000647 | 1073759862 |
| bin-log.000648 | 1073757229 |
| bin-log.000649 | 1073776952 |
| bin-log.000650 | 1073791824 |
| bin-log.000651 | 1073743420 |
| bin-log.000652 | 1073785139 |
| bin-log.000653 |  338795678 |
+----------------+------------+
9 rows in set (0.00 sec)

You could then use the mysqlbinlog utility to dump a text representation of all the SQL commands executed within specified timeframes along with the timestamps.
The options to use are

--start-datetime
--stop-datetime

What to do next
Go find the folder where the binary logs are kept. From the command line run this
ls -l bin-log.*

-rw-rw---- 1 mysql mysql  338795678 Aug 18 12:30 bin-log.000653
-rw-rw---- 1 mysql mysql        351 Aug 18 11:31 bin-log.index

The datetime stamp for each file represents the last time the binlog received SQL commands.
You would request the commands by the timeframe and by the binlog names ordered by timestamp
To see all SQL commands executed from midnight to 8:00AM today, you run this
SQLCMDS=/tmp/SQLCommands.txt
DT1=&quot;2014-08-18 00:00:00&quot;
DT2=&quot;2014-08-18 08:00:00&quot;
BINLOGS=&quot;bin-log.000649 bin-log.000650 bin-log.000651&quot;
mysqlbinlog --start-datetime=&quot;${DT1}&quot; --stop-datetime=&quot;${DT2}&quot; ${BINLOGS} &gt; ${SQLCMDS}

The output file, /tmp/SQLCommands.txt, will contain every INSERT, UPDATE, DELETE, and DDL command executed in the timeframe you requested. Just make sure you supply the necessary binlogs. If you include all binlogs, the mysqlbinlog dump will still work but would take longer because it would parse through binary logs it does not need (i.e., you don't need to parse bin-log.000645 - bin-log.000648, bin-log.000652, bin-log.000653).
Give it a Try !!!

If you want to see everything, including the SELECTs, you go with Craig Efrein's answer.

@CraigEfrein made a excellent point in his comment

Activating bin-logs also have an impact on performance and disk space.

To reduce disk I/O based on binary logging, you should config binlogs to be stored on a separate disk. See my old post How do I determine how much data is being written per day through insert, update and delete operations? (under the subheading SSD LIFESPAN)
