However, removing the open cursor with the JDBC method invalidates the positioned update.A CREATE or DROP INDEX statement or an ALTER TABLE statement for the target table of a prepared positioned update invalidates the prepared positioned update statement.It will refer to the state corresponding to the time you executed COMMIT.This means if you have already used COMMIT 10 times, ROLLBACK will have an effect on the last execution you have performed.A searched update statement depends on the table being updated, all of its conglomerates (units of storage such as heaps or indexes), all of its constraints, and any other table named in the WHERE clause or SET expressions.A CREATE or DROP INDEX statement or an ALTER TABLE statement for the target table of a prepared searched update statement invalidates the prepared searched update statement.

You cannot restore data to a state corresponding to an earlier COMMIT.We want to also update the values of Col 2 and Col 3 only.The most easiest and common way is to use join clause in the update statement and use multiple tables in the update statement.SQL UPDATE JOIN means we will update one table using another table and join condition. I have updated customer table that contains latest customer details from another source system.I want to update the customer table with latest data.
