I've been trying to pivot a very sample table:
TYPE | COUNT
___________________
'CHAINS' | '38'
'INDEP' | '64'
'SUPER' | '25'
Yup, it's that simple. I've been reading tutorials, Stackoverflow answers and I've been looking for a good tutorial about transposing a table. I just can't understand it very well and I haven't been able to accomplish the following result:
CHAINS | INDEP | SUPER
_______________________
38 | 64 | 25
I know there are other questions similar to this one, but I just can't get the point from reading. Most examples use multiple tables to explain or just have code with no explanmation, and I can't undestrand what's needed to do this. Can somebody please explain me in detail how can I accomplish this pivoted table??
THANKS A LOT!!
EDIT 1:
With the tutorials I've read, I've manage to get the following:
CHAINS | INDEP | SUPER
_______________________
38 | NULL | NULL
NULL | 64 | NULL
NULL | NULL | 25
I'd like the data to be in a single row without those null. I know there are tutorials and answers about this but I just don't understand clearly. I'd like an explanation of whats the logic to do this pivot table.
@bluefeet told me I needed an aggregate function. With sum() I got a single row
EDIT 2:
This is the query I'm using works (thansk to @bluefeet) but it's not dynamic: I can't know for sure what columns I'll need.
SELECT
sum(case when sq.TYPE = 'CHAINS' then sq.COUNT end) AS CHAINS,
sum(case when sq.TYPE = 'INDEP' then sq.COUNT end) AS INDEPE,
sum(case when sq.TYPE = 'SUPER' then sq.COUNT end) AS SUPER
from subquery1 sq
How can I get a similar result but with a dynamic query? THANKS
