Question

How can I update a complete data row by using a data row from another table.

Example:

Table A

ID   |   NAME    |   ...   |
----------------------------
 1   |   Test    |   ...   |
 2   |   Test2   |   ...   |



Table B

ID   |   NAME    |   ...   |
----------------------------
 1   |   Test97  |   ...   |

So I want to copy the content of a single row of Table B to Table A and override existing values. I do not want to name all columns. The contents of table A and B are redundant.

Summarize:
I want an equivalent to the following INSERT Statement as an UPDATE Statement:

INSERT INTO destTable 
VALUES  (SELECT * FROM TABLE2)
FROM srcTable 

Any hint, even telling me that its not possible, is very appricated.

Answer 1

you can update a set of columns (you still have to list the columns once):

SQL> UPDATE table_a
  2     SET (ID, NAME, etc)
  3         = (SELECT * FROM table_b WHERE table_b.id = table_a.id)
  4   WHERE table_a.id IN (SELECT ID FROM table_b);

1 row updated
