Pivoting in Sybase SQL Query?

Question

I am looking for a way to pivot the following results...

ID | Group_Level | Group_Values
1  | Division    | Value 1 
2  | Department  | Value 2
3  | Class            


        

Answer 1

You need some key to define the set of 3 rows. Then, you just self JOIN

So for data like this...

ID | GroupID | Group_Level | Group_Values
1  | 1 | Division    | Value 1
2  | 1 | Department  | Value 2
3  | 1 | Class       | Value 3
4  | 2 | Division    | Value 1
5  | 2 | Department  | Value 2
6  | 2 | Class       | Value 3

you'd have

SELECT
   Div.GroupID, Div.Group_Values, Dept.Group_Values, Cl.Group_Values
FROM
   MyTable Div
   JOIN
   MyTable Dept ON Div.GroupID = Dept.GroupID
   JOIN
   MyTable Cl ON Div.GroupID = Cl.GroupID
WHERE
   Div.Group_Level = 'Division'
   AND
   Dept.Group_Level = 'Department'
   AND
   Cl.Group_Level = 'Class'
