DECLARE @ORIGINAL_ID AS BIGINT
SELECT FID001 INTO #Temp001_
FROM INBA004 WHERE RS_DATE>='1999-01-01'

SELECT TOP 1 @ORIGINAL_ID=FID001 FROM #Temp001_ ORDER BY FID001
PRINT CAST (@ORIGINAL_ID AS VARCHAR(100))+' STARTED'
SELECT DISTINCT FID001
INTO #OUT_FID001
FROM OUTTR009 WHERE TRANSACTION_ID IN (SELECT TRANSACTION_ID FROM
INTR00100 WHERE FID001 = @ORIGINAL_ID)
UPDATE A SET RCV_Date=B.TIME_STAMP
FROM OUTTR009 A INNER JOIN INTR00100 B
ON A.TRANSACTION_ID=B.TRANSACTION_ID
WHERE A.FID001 IN (SELECT FID001 FROM #OUT_FID001)
AND B.FID001=@ORIGINAL_ID
UPDATE A SET Sending_Date=B.TIME_STAMP
FROM INTR00100 A INNER JOIN OUTTR009 B
ON A.TRANSACTION_ID=B.TRANSACTION_ID
WHERE A.FID001=@ORIGINAL_ID
AND B.FID001 IN (SELECT FID001 FROM #OUT_FID001)
DELETE FROM #Temp001_ WHERE FID001=@ORIGINAL_ID
DROP TABLE #OUT_FID001

DECLARE @x INT
SET @x = 1
WHILE @x < 44,000,000  -- Set appropriately
BEGIN
    UPDATE Table SET a = c+d where ID BETWEEN @x AND @x + 10000
    SET @x = @x + 10000
END
Make sure that ID column has a CI on.
