Saya rasa Anda ingin
UPDATE table1 cs
SET cs.abc = (SELECT tc.abc
FROM table2 cgl,
table3 tc
WHERE cgl.prd_id = tc.prd_id
AND cgl.prd_ver = tc.prd_ver
AND cgl.py_id = tc.py_id
AND cgl.typ_id = tc.tpy_id
AND cd.common_column = cgl.common_column)
WHERE EXISTS (SELECT 1
FROM table2 cgl,
table3 tc
WHERE cgl.prd_id = tc.prd_id
AND cgl.prd_ver = tc.prd_ver
AND cgl.py_id = tc.py_id
AND cgl.typ_id = tc.tpy_id
AND cd.common_column = cgl.common_column)
Pembaruan:Selain perubahan pada nama kolom dan tabel, jawaban awal saya tampaknya berfungsi dengan data sampel yang Anda posting. Perhatikan bahwa memposting DDL dan DML selalu lebih mudah sehingga kami dapat mereproduksi tabel dan data Anda daripada meminta kami mengonversi data Anda ke DDL dan DML.
Jika saya membuat tabel dan data Anda
SQL> create table table1 (
2 prd_id number,
3 prd_ver number,
4 py_id number,
5 typ_id number,
6 column_used_for_update varchar2(10)
7 );
Table created.
SQL> begin
2 insert into table1 values( 1, 1, 1, 1, 'VALUE1' );
3 insert into table1 values( 2, 3, 4, 5, 'VALUE2' );
4 end;
5 /
PL/SQL procedure successfully completed.
SQL> create table table2 (
2 prd_id number,
3 prd_ver number,
4 py_id number,
5 typ_id number,
6 common_column varchar2(10)
7 );
Table created.
SQL> begin
2 insert into table2 values( 1, 1, 1, 1, 'A' );
3 insert into table2 values( 1, 1, 1, 1, 'B' );
4 insert into table2 values( 2, 3, 4, 5, 'C' );
5 end;
6 /
PL/SQL procedure successfully completed.
SQL> create table table3 (
2 common_column varchar2(10),
3 column_to_update varchar2(10)
4 );
Table created.
SQL> begin
2 insert into table3 values( 'A', null );
3 insert into table3 values( 'B', null );
4 insert into table3 values( 'C', null );
5 end;
6 /

SQL> commit;
Commit complete.
Kemudian sesuaikan nama tabel dan kolom dari jawaban awal saya, ternyata update berfungsi dengan benar
