I can’t figure out how to combine the results from one select statement with the results from another so that the results are side by side. Using Union causes the results of the second statement to add rows below the first results.
The first select has sales_rep_id and number_of_customers.
The second select has total_number_of_parts and total_customer_sales.
I had to create ‘null as’ statements to create the proper columns in each of the statements so that the results from the second select wouldn’t go into the columns for the first.
So for the first result we have: 3, 3, null, null
The second result would have: null, null, 12, 171.94
What I want is for it to be: 3, 3, 12, 171.94
MySQL is not fun and this is driving me crazy, I have been stuck on this for 2 days. Any guidance would be appreciated.
Answer:-
Note:- You can use Cartesian product of two tables.(it will add each row of first table to each row of second table).
Select * from (first select statement) , (second select statement).
Note:- if you have any further doubt feel free to write in the comment box.
