This is a complete book on PL/SQL with everything you need to know to write efficient and complex PL/SQL code.

Rows Only does not seem to work with the FOR UPDATE clause.

When the Fetch clause is used with a cursor having a FOR UPDATE clause, the PL/SQL unit fails when we try to open the cursor with an ORA-02014: cannot select FOR UPDATE from view with DISTINCT, GROUP BY, etc. The error description shows that the internal mechanism for the Fetch clause uses either a DISTINCT or a GROUP BY clause which is not permitted alongside the FOR UPDATE clause.

For example, consider the following update operation. If the operation results in an upsert, the collection must already exist.

Do not explicitly set the write concern for the operation if run in a transaction.

When we want to update or delete the cursor fetched row(s) from the database, we don’t have to form In the below code listing, the employees joined before the year 2000 are archived and during the cursor process, no other session is permitted to make any changes to those employees using the FOR UPDATE clause.

The employee deletion from the transaction table is performed using the WHERE CURRENT OF clause as shown below.

I know I can use "Select by Attributes" but sometimes I know exactly what I want to select or the query would be too complicated.
