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
);
