Question

Hi
I must Upload a table (A) from other Table (B) have 6 000 000 records,
The Process can stop or Crashed when some user (donk) turn off microcomputer ( I commit each 1000 records)
is there some way to save Rowid of Table B and When begin new processing It begin last position , wihtout create other columns or begin from first register ?
tks

Answer 1

CURSOR CTABLE1 IS
SELECT ROWID row_id
FROM TABLE1
CURSOR CTABLE2 IS
SELECT ROWID row_id
FROM TABLE2
CURSOR cTABLE3IS
SELECT ROWID row_id FROM TABLE3
FOR REG_TABLE1 IN cTABLE1 LOOP
UPDATE TABLE1
SET FIED01 = NULL,
FIELD02 = NULL,
FIELD0N = NULL
WHERE ROWID = REG_TABLE1.row_id;
IF w_quan_commit = 1000 THEN
COMMIT;
w_quan_commit := 0;
ELSE
w_quan_commit := w_quan_commit + 1;
END IF;
END LOOP;
DO FOR TABLE2 AND TABLE3
This dealy about 2 or 2.5 hours
NOW Begin processing below == 6 hours !!!!
