How can Oracle be used to update multiple tables in a related manner?

In Oracle, you can use the UPDATE statement to update data by combining multiple tables. Here is an example:

Assume there are two tables: Table A and Table B, which have a common field ID. We need to update the value of a certain field in Table A to Table B.

Firstly, we can use the UPDATE statement to link table A and table B, as shown below:

Update field2 in tableB with the values of field1 from tableA where the ID matches.

In this example, we utilized a subquery to connect table A and table B by using an INNER JOIN and specifying the joining condition (a.ID = b.ID).

Next, we use the UPDATE statement to update the value of field1 in table A to field2 in table B, specifying the fields and values to be updated with the SET clause.

Please note that a subquery is used here to associate tables A and B, as Oracle does not directly support using multiple table joins in an UPDATE statement.
