Update Nested Table Problem

Question

Hi All,
I have a update problem in nested table.
Below is my query:
CREATE OR REPLACE TYPE TRACER.SEARCH_DATA AS TABLE OF VARCHAR2(20);
UPDATE TRACER_SEARCH_SCHEDULE_LOT_NUM
SET NOT_FOUND_SOR_LOT_NUM = SEARCH_DATA(
SELECT
COLUMN_VALUE
FROM
TABLE (SELECT SORTING_LOT_NUMBER FROM TRACER_SEARCH_SCHEDULE_LOT_NUM WHERE JOB_ID = 8)
WHERE
TRIM(COLUMN_VALUE) NOT IN (SELECT DISTINCT (SORTING_LOT_NUMBER) FROM SEARCH_SCHEDULE_RESULT_LOT_NUM WHERE JOB_ID = 8)
) WHERE JOB_ID = 8;
ORA-00936: missing expression
or I try as following
DECLARE
sor_lot_num_not_found SEARCH_DATA :=
SEARCH_DATA
SELECT
FROM
TABLE (SELECT SORTING_LOT_NUMBER FROM TRACER_SEARCH_SCHEDULE_LOT_NUM WHERE JOB_ID = 8)
WHERE
TRIM(COLUMN_VALUE) NOT IN (SELECT DISTINCT (SORTING_LOT_NUMBER) FROM SEARCH_SCHEDULE_RESULT_LOT_NUM WHERE JOB_ID = 8)
BEGIN
UPDATE TRACER_SEARCH_SCHEDULE_LOT_NUM SET NOT_FOUND_SOR_LOT_NUM = sor_lot_num_not_found WHERE JOB_ID = 8;
END;
ORA-06550: line 5, column 9:
PLS-00103: Encountered the symbol "SELECT" when expecting one of the following:
( ) - + case mod new not null others <an identifier>
table avg count current exists max min prior sql stddev sum

ORA-06550: line 11, column 5:

PLS-00103: Encountered the symbol "end-of-file" when expecting one of the following:
begin case declare end exception exit for goto if loop mod
null pragma raise return select update while with
<an identifier> <a double-quoted d
I have try on the Select Statement, it work. So is it the way that I assign data from nested table and update method is wrong?

Hi,
I think MULTISET operators might interest you.

Not tested :
UPDATE tracer_search_schedule_lot_num
SET not_found_sor_lot_num =
      sorting_lot_number
      MULTISET EXCEPT ALL
      CAST(
        MULTISET(
          SELECT distinct sorting_lot_number
          FROM search_schedule_result_lot_num
          WHERE job_id = 8
        AS search_data
WHERE job_id = 8
;
