A bulk bind,which uses the FORALL keyword, can improve the performance of INSERT, UPDATE, or DELETE statements that reference collection elements. The PL/SQL block inExample 6-9increases the salary for employees whose manager's ID number is 7902, 7698, or 7839, with and without bulk binds....

What if there is a parent delete with “on delete cascade” on the child. Do inserts, updates, deletes or merges produce any unexpected results (e.g. double / quadruple counting); what if they’re PL/SQL forall bulk processing, what if (e.g.) you update or delete through a join ...
For example, if group NetworkAdmins is given permission to manage Virtual Cloud Networks (VCN) in the root compartment, that group will be able to manage VCNs in all compartments. Currently, all users and groups are created inside the root compartment. Policies can be used to grant them ...
A PL/SQL RECORD is the datatype that corresponds to a row in a schema-level table. It is the natural construct to use when manipulating table rows programatically, especially when a row is read (via SELECT, UPDATE...RETURNING or DELETE...RETURNING), manipulated programatically, and then rec...
