У кого-нибудь есть пример использования WITH и UPDATE в запросе в PLSQL?
Я глотал и гуглил безуспешно.
Вот что я пытаюсь сделать
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
)
По сути, это обновление измерения типа II.
