I want the total count of the user visited this product

My Query

"select Id , proudct_id , category , user_id , count(click_count) as cnt from user_view where user_id =102 group by product_id order by rand() limit 0,10"

But the output is showing only one count

OUTPUT

 Id | product_id | category | user_id | cnt
  1     10          watch      102       1         

EXPECTED OUTPUT IS

 Id | product_id | category | user_id |  cnt  
  1     10         watch       102       17  

Answer 1

You should be using sum aggregate function instead of count which will count number of rows. So your query should be something like:

  select Id , product_id , category , user_id , SUM(click_count) as sum ...

Answer 2

Try this:

select Id , proudct_id , category , user_id , SUM(click_count) as cnt
from user_view
 where user_id =102
order by rand()
limit 0,10
group by product_id

COUNT() always returns the number of items, not the sum of values. So use SUM() .

Answer 3

"select Id , proudct_id , category , user_id , count(click_count) as cnt from user_view where user_id =102 group by user_id, product_id order by rand() limit 0,10"
