I have two table login_info_1,login_info_2 which has a column user_id in each table
select user_id,count(user_id) as cnt from login_info_1 group by user_id;
which gives me result like this
user_id cnt 101 4 102 5 103 1 107 7
same for the second table select user_id,count(user_id) as cnt2 from login_info_2 group by user_id;
user_id cnt 101 3 102 2 103 2 107 1
I want to combine these two tables and the results should look like this
user_id cnt 101 7 102 7 103 3 107 2
