Oracle SQL-使用WITH语句时无法更新

Question

I am trying to update a column based on virtual dataset created via a WITH statement. I have simplified the statement as much as possible to get to the root issue. It appears that UPDATE does not work when using a WITH statement, but I can't believe this is accurate. The error I am getting is

ORA-00928: missing SELECT keyword

Here is my SQL statement.

with TEMP1 as (
   select  NN_NAME
   from SMB.ACCOUNTS
)   

update SALES_PLAY_MATRIX_WORKING
set FY16_FOCUS = 'Y' where NN_NAME in ( select TEMP1.NN_NAME from TEMP1)

If I convert the 2nd portion of the statement to just a pure SELECT, it works...

with TEMP1 as (
      select  NN_NAME
      from SMB.ACCOUNTS
)   

(
    select TEMP1.NN_NAME 
    from TEMP1)

Answer 1

In Oracle, with does not go just at the beginning of a query. It can go before any select . So:

update SALES_PLAY_MATRIX_WORKING
    set FY16_FOCUS = 'Y'
    where NN_NAME in (
        with TEMP1 as (
              select NN_NAME
              from SMB.ACCOUNTS
             )
        select TEMP1.NN_NAME 
        from TEMP1
       );

Answer 2

I will suggest go for nested query that may solve your issue

UPDATE SALES_PLAY_MATRIX_WORKING
SET FY16_FOCUS = 'Y' 
WHERE NN_NAME IN ( SELECT NN_NAME FROM SMB.ACCOUNTS)

Answer 3

You could use a merge statement:

MERGE INTO SALES_PLAY_MATRIX_WORKING dst
USING ( SELECT NN_NAME FROM SMB.ACCOUNTS ) src
ON    ( dst.NN_NAME = src.NN_NAME )
WHEN MATCHED THEN
  UPDATE SET FY16_FOCUS = 'Y';

or more simply:

MERGE INTO SALES_PLAY_MATRIX_WORKING dst
USING SMB.ACCOUNTS src
ON    ( dst.NN_NAME = src.NN_NAME )
WHEN MATCHED THEN
  UPDATE SET FY16_FOCUS = 'Y';
