Oracle SQL Developer：如何使用PIVOT函数将行转置为列

Question

I'm attempting to create a query to transpose rows into columns using the PIVOT function.

This is the contact table I want to transpose into rows:

   PARTYID CONTACTTEXT  CONTACTTYPECD
---------- ------------ -------------
       100 0354441010               1
       100 0355551010               2
       100 0428105789               3
       100 abc@home.com             4

My intended result:

   PARTYID PHONE        FAX          MOBILE       EMAIL      
---------- ------------ ------------ ------------ ------------
       100 0354441010   0355551010   0428105789   abc@home.com

My query:

SELECT * FROM 
  ( 
    SELECT partyId, contacttext, contacttypecd 
    FROM CONTACT 
    WHERE partyId = 100; 
  ) 
  PIVOT ( 
    MAX(contacttext) 
  FOR contacttypecd in (1 Phone, 2 Fax, 3 Mobile, 4 Email)); 

Errors I'm getting:

Error starting at line 9 in command: 
FOR contacttypecd in (1 Phone, 2 Fax, 3 Mobile, 4 Email)) 
Error report: 
Unknown Command 

The reason for my problem was because my Oracle database version (Oracle9i) did not support the PIVOT function. Here's how to do it in a different way:

SELECT PartyCD
  ,MAX(DECODE(t.contacttypecd, 1, t.contacttext)) Phone
  ,MAX(DECODE(t.contacttypecd, 2, t.contacttext)) Fax
  ,MAX(DECODE(t.contacttypecd, 3, t.contacttext)) Mobile
  ,MAX(DECODE(t.contacttypecd, 4, t.contacttext)) Email
FROM 
  (
    SELECT partyid, contacttext, contacttypecd
    FROM CONTACT
    WHERE partyid = 100
  ) t
 GROUP BY PartyID

Answer 1

You have a stray semi-colon in your statement, after:

    WHERE partyId = 100; 

Remove that to make it:

SELECT * FROM 
  ( 
    SELECT partyId, contacttext, contacttypecd 
    FROM CONTACT 
    WHERE partyId = 100
  ) 
  PIVOT ( 
    MAX(contacttext) 
  FOR contacttypecd in (1 Phone, 2 Fax, 3 Mobile, 4 Email));

   PARTYID PHONE        FAX          MOBILE       EMAIL      
---------- ------------ ------------ ------------ ------------
       100 0354441010   0355551010   0428105789   abc@home.com

It's being seen as multiple statements; the first is incomplete because it's missing a closing parenthesis (so gets ORA-00907), the second starts with that parenthesis and gets the error you reported, and then each subsequent line gets the same error. You only seem to be looking at the last reported error - it's usually much more helpful to start with the first error, clear that, and then move onto the next if it still exists.
