Question

This is below data in Table2

ID2        |    Count2
-----------+-----------
1345653         5
534140349       5
682527813       4
687612723       3
704318001       5

This is my below data in Table1

ID1        |    Count1
-----------+-----------
1345653         4
704318001       4

1. If you see the above table this 1345653 in Table2 has 5 count but in Table1 it has 4 count, In the same way this ID 704318001 in Table2 has 5 count but in Table1 it has 4 count.
2. And also one more thing I need to show, I don’t know whether it is possible to do it or not. I want to show the sum of each column also in the end, like sum of Count2 column in the end and sum of Count1 column in the end.

So I need to show like this in the Output. I have my working query for the first part, but I am not sure how to work on second part.

ID              Count2   Count1
-----------------------------------
1345653         5        4
534140349       5        0
682527813       4        0
687612723       3        0
704318001       5        4
               22        8

Is this possible in sql? If Yes, how can I achieve that?

I have created the SQL fiddle in which only the count thing is working(means first part), And I am not sure how to add the sum of each column feature in that SQL query.

Answer 1

Will it work for you?

select id2,  SUM(count2),SUM(coalesce(count1, 0)) as count1 
from table2 
 left outer join table1 
  on id1=id2
 group by id2
 with rollup

It’s mysql syntax, but most RDMS support ROLLUP with a small difference in syntax
