PIVOT Statement - ORA-00936

Question

I have a question about a PIVOT Statement
DB: 11.2.0.3.0
I have Table x with 3 Columns (c1,c2,c3)
C1 C2 C3
A | T | 1
A | P | 1
M | S | 1
D | T | 1
D | P | 1
D | D | 1
with this select the result is ok
SELECT * FROM
(SELECT c1, c2, c3 FROM x)
PIVOT
max(c3)
FOR c2
IN ('T', 'P', 'D', 'S')
ORDER BY c1;
gives me the correct result (is malformed in this Forum !)
C1 'T' 'P' 'D' 'S'
A 1 1
D 1 1 1
M 1
but thies Select give me ORA-00936: missing expression
SELECT * FROM
(SELECT c1, c2, c3 FROM x)
PIVOT
max(c3)
FOR c2
IN (select distinct c2 from x )
ORDER BY c1;
is the used statment "*select distinct c2 from x*" not allowed in this IN Clause ?

alfredNo..
You cannot use subquery here..
For completely dynamic pivoting - check FAQ: {message:id=9360005} It is explained under the heading - Dynamic Pivoting.
And if you use PIVOT XML, you can have a subquery.. You will get an XML output..
