计数mysql数据库行中的值

Question

I have a table in my database that looks like this.

id    count
-----------
1      23
2      20
3      12
4      4

The "count" column will periodically change. How would I add all the values in the count column and display them on the front end? So for example, in this case they would add up to 59.

Answer 1

select sum(count) from table_name

Answer 2

SELECT SUM(`count`) FROM myTable
