try this one query in mysql

<pre><code>SELECT SEC_TO_TIME(SUM(TIME_TO_SEC(time_duration))) FROM yourTable;

hope this will help you

You may use the following SQL Query:--- 

<pre><code>SELECT SUM(time_duration) FROM table_name;
</code></pre>

 
I hope that it will work according to your requirement.

blocks|key|5304510|text|尝试以下方法：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5304511|`sum(time_duration)+as+time_duration`+|code-block|syntax|javascript|5304512|在您的Mysql查询中。|5304513|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Try this method:

<pre><code>`sum(time_duration) as time_duration` 
</code></pre>

in your Mysql query.

blocks|key|1520695|text|假设time_duration为varchar列，请尝试以下操作：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1520696|+++select+TIME_FORMAT(SEC_TO_TIME(SUM(TIME_TO_SEC(TIME_FORMAT(time_duration,+'%25H:%25i')))),'%25H:%25i')+time_duration+

try this assuming time_duration is varchar column :

<pre><code> select TIME_FORMAT(SEC_TO_TIME(SUM(TIME_TO_SEC(TIME_FORMAT(time_duration, '%H:%i')))),'%H:%i') time_duration 
 from table1;
</code></pre>

<a href="http://sqlfiddle.com/#!2/4a764/1" rel="nofollow">DEMO</a>

Ops: i guessed you have Hours and minutes , if you have minutes and seconds just change the format.

I need a MySQL query for the following. I have a table of time duration as such below:

<pre><code>`hsncs_tbl`

+----+-----------------+
| Id | time_duration |
+----+-----------------+
| 1 | 0:12 |
 ---- -----------------
| 2 | 0:18 |
 ---- ----------------- 
</code></pre>

Using a MySQL query, I need to be able to calculate these time duration. So from the table above I would get the answer of 0:30.

I tried this code many times, but still not working

<pre><code>SELECT SEC_TO_TIME(SUM(TIME_TO_SEC(time_duration))) FROM hsncs_tbl
</code></pre>

Here's the screenshot of my code together with the output.
