Filtering/ORDER BY – Practice

I ran into a small issue with a order I am trying to do and not sure if there is a solution to what I am trying to accomplish. I have the following table created… CustomerID is PK and I can’t change the numbers around.

Customer ID     ProductID     State
1   100 Alaska
2   100 California
3   100 North Carolina
4   100 South Carolina
5   101 Alabama
6   101 Virginia
7   101 Michigan
8   103 Hawaii
9   103 Kansas
10  103 Montana

Customer ID     ProductID     State1   100 Alaska2   100 California3   100 North Carolina4   100 South Carolina5   101 Alabama6   101 Virginia7   101 Michigan8   103 Hawaii9   103 Kansas10  103 Montana ​

The goal is to get the table to look like this:

1   100 Alaska
2   100 California
11  100 Delaware
3   100 North Carolina
4   100 South Carolina
5   101 Alabama
6   101 Virginia
7   101 Michigan
8   103 Hawaii
9   103 Kansas
10  103 Montana

 
1   100 Alaska2   100 California11  100 Delaware3   100 North Carolina4   100 South Carolina5   101 Alabama6   101 Virginia7   101 Michigan8   103 Hawaii9   103 Kansas10  103 Montana ​

The first part of what I’m trying to accomplish is adding the following record/row/entry (seen here)

11  100 Delaware

 
11  100 Delaware​

I was successfully able to add the row using INSERT INTO. The next task I wanted to accomplish was sorting (ORDER BY) the table by ProductID AND State. As you can see I am trying to move that new row to the new position as seen above.

As of now I have tried:

ORDER BY ProductID, State ASC;

 
ORDER BY ProductID, State ASC;​

My table looks like this

1   100 Alaska
2   100 California
11  100 Delaware
3   100 North Carolina
4   100 South Carolina
5   101 Alabama
7   101 Michigan
6   101 Virginia
8   103 Hawaii
9   103 Kansas
10  103 Montana

 
1   100 Alaska2   100 California11  100 Delaware3   100 North Carolina4   100 South Carolina5   101 Alabama7   101 Michigan6   101 Virginia8   103 Hawaii9   103 Kansas10  103 Montana ​

This changes the order of customer ID 5,6,7 which I am trying to avoid.

I tried to create a CASE but had no luck and wasn’t able to “double sort” (error because my first 2 columns are int and can’t compare to my 3rd column)

Any recommendations? Advice? Is what I’m trying to accomplish even possible?

Answer

Probably this is what you are after?

select * 
from t
order by productId, case when productId=100 then state end,
customerId

 
select * from torder by productId, case when productId=100 then state end,customerId​
