can oracle types be updated like tables?
- by Omnipresent
I am converting GTT's to oracle types as explained in an excellent answer by APC. however, some GTT's are being updated based on a select query from another table. For example:
UPDATE my_gtt_1 c
SET (street, city, STATE, zip) = (SELECT src.unit_address,
src.unit_city,
src.unit_state,
src.unit_zip_code
FROM (SELECT mbr.ROWID row_id,
unit_address,
RTRIM(a.unit_city) unit_city,
RTRIM(a.unit_state) unit_state,
RTRIM(a.unit_zip_code) unit_zip_code
FROM table_1 b,
table_2 a,
my_gtt_1 mbr
WHERE type = 'ABC'
AND id = b.ssn_head
AND a.h_id = b.h_id
AND row_id >= v_start_row
AND row_id <= v_end_row) src
WHERE c.ROWID = src.row_id)
WHERE state IS NULL
OR state = ' ';
if my_gtt_1 was not a global temporary table but an oracle collection type then is it possible to do updates this complex? Or in these cases we are better off using the global temporary table?
