Question

Does anyone have a sample of how to use WITH and UPDATE in a query in PLSQL?

I binged and googled without success.

Here is what I am trying to do

WITH
OldRecords AS
(
  SELECT 'New Records' as RecordLabel, rowid, OrDev.* 
  FROM CDR.MSRS_OR_ORDEV OrDev
  WHERE 1=1
    AND OrDev.ASOFENDDATETIME IS NULL
    AND OrDev.REPORTSTARTDATE = to_date ('7/1/2010', 'mm/dd/yyyy')
    AND OrDev.REPORTENDDATE = to_date ('7/31/2010', 'mm/dd/yyyy')
    AND OrDev.downloadrequestid <> 3
), 
NewRecords AS
(
  SELECT 'Old Records' as RecordLabelrowid, OrDev.* 
  FROM CDR.MSRS_OR_ORDEV OrDev
  WHERE 1=1
    AND OrDev.ASOFENDDATETIME IS NULL
    AND OrDev.REPORTSTARTDATE = to_date ('7/1/2010', 'mm/dd/yyyy')
    AND OrDev.REPORTENDDATE = to_date ('7/31/2010', 'mm/dd/yyyy')
    AND OrDev.downloadrequestid = 3
)
UPDATE CDR.MSRS_OR_ORDEV SET ASOFENDDATETIME = GETDATE()
WHERE RowID IN
(
  SELECT OldRecords.RowId
  FROM OldRecords
    INNER JOIN NewRecords
      ON  OldRecords.Customer_Id = NewRecords.Customer_Id
      AND OldRecords.BusinesKey1 = NewRecords.BusinesKey1
      AND OldRecords.BusinesKey2 = NewRecords.BusinesKey2
)

Basically this is a Type-II dimension update.

This is how to use WITH in an UPDATE in PLSQL. Note that this only works for a single column update.

UPDATE CDR.MSRS_OR_ORDEV 
SET ASOFENDDATETIME = sysdate
WHERE RowID IN
(
  WITH
  OldRecords AS
  (
    SELECT rowid, OldRecords.* 
    FROM CDR.MSRS_OR_ORDEV OldRecords
    WHERE 1=1
      AND OldRecords.ASOFENDDATETIME IS NULL
      AND OldRecords.REPORTSTARTDATE = to_date ('7/1/2010', 'mm/dd/yyyy')
      AND OldRecords.REPORTENDDATE = to_date ('7/31/2010', 'mm/dd/yyyy')
      AND OldRecords.downloadrequestid <> 3
  ), 
  NewRecords AS
  (
    SELECT rowid, NewRecords.* 
    FROM CDR.MSRS_OR_ORDEV NewRecords
    WHERE 1=1
      AND NewRecords.ASOFENDDATETIME IS NULL
      AND NewRecords.REPORTSTARTDATE = to_date ('7/1/2010', 'mm/dd/yyyy')
      AND NewRecords.REPORTENDDATE = to_date ('7/31/2010', 'mm/dd/yyyy')
      AND NewRecords.downloadrequestid = 3
  )
  SELECT OldRecords.RowId
  FROM OldRecords
    INNER JOIN NewRecords
      ON  OldRecords.BusinesKey1 = NewRecords.BusinesKey1
      AND OldRecords.BusinesKey2 = NewRecords.BusinesKey2
);
