Rewriting into an update - I am testing a multiple column - join update:
1 update
2 (select a.last_name, b.last_name
3 from emp a, person b
4 where a.emp_id =3D b.person_id)
5* set a.last_name =3D b.last_name
SQL> desc person;
Name Null? Type
----------------------------------------- -------- =
----------------------------
PERSON_ID NUMBER
LAST_NAME VARCHAR2(50)
FIRST_NAME VARCHAR2(50)
LOADDATE DATE
SQL> desc emp;
Name Null? Type
----------------------------------------- -------- =
----------------------------
EMP_ID NUMBER(38)
LAST_NAME VARCHAR2(50)
FIRST_NAME VARCHAR2(50)
LOADDATE DATE
When I execute the above update, I get the error:
set a.last_name =3D b.last_name
*
ERROR at line 5:
ORA-00904: "B"."LAST_NAME": invalid identifier
What am I doing wrong?
