SQL Update statement using nested sub select

Posted on 2008-10-23

I am trying to bind the data in the top row of a sub select to the column in an update statement.  I've attached the PL/SQL code snippet.

I get the following error:  ORA-00904:  "TMP"."ACCT_ID": invalid identifier

I believe this is due to the fact that the sub query isn't directly linked to the main update statement's table but I don't know how to make this connection using an update statement.

Any help would be greatly appreciated.
UPDATE CM_CO$DLQCS TMP

SET MASTER_SA_ID = (  SELECT SA_ID 

                      FROM (  SELECT SA.SA_ID

                              FROM CI_SA SA

                                , CI_SA_TYPE SA_TYPE

                              WHERE SA.ACCT_ID = TMP.ACCT_ID

                                AND SA.SA_TYPE_CD = SA_TYPE.SA_TYPE_CD

                                AND SA_TYPE.SUB_SA_SW = 'N'

                                AND SA_TYPE.SVC_TYPE_CD = 'E'

                                AND SA.SA_STATUS_FLG < 40

                              ORDER BY SA.START_DT DESC

                           )

                      WHERE ROWNUM = 1

                   );

try this
UPDATE CM_CO$DLQCS TMP

SET MASTER_SA_ID = ( select sa_id from 

										 (	SELECT ACCT_ID, SA_ID 

                      FROM (  SELECT SA.ACCT_ID, SA.SA_ID

                              FROM CI_SA SA

                                , CI_SA_TYPE SA_TYPE

                              WHERE SA.SA_TYPE_CD = SA_TYPE.SA_TYPE_CD

                                AND SA_TYPE.SUB_SA_SW = 'N'

                                AND SA_TYPE.SVC_TYPE_CD = 'E'

                                AND SA.SA_STATUS_FLG < 40

                              ORDER BY SA.START_DT DESC

                           )

                      WHERE ROWNUM = 1

                     ) BB

                     where TMP.ACCT_ID = BB.ACCT_ID

Try this, should work
UPDATE CM_CO$DLQCS TMP

SET MASTER_SA_ID = (select SA_ID from (

select ACCT_ID , SA_ID

FROM (

SELECT SA.ACCT_ID , SA.SA_ID, row_number() over(partition by SA.ACCT_ID order by SA.START_DT desc) rn

FROM CI_SA SA , CI_SA_TYPE SA_TYPE

WHERE 

SA.SA_TYPE_CD = SA_TYPE.SA_TYPE_CD

AND SA_TYPE.SUB_SA_SW = 'N'

AND SA_TYPE.SVC_TYPE_CD = 'E'

AND SA.SA_STATUS_FLG < 40 ) 

where rn = 1 ) A

where A.ACCT_ID = TMP.ACCT_ID;
