What is Understanding SQL Cursors in PL/SQL about?

Cursors are memory areas in SQL that allow for the retrieval and processing of data one row at a time, with two main types: implicit and explicit cursors. Implicit cursors are automatically created by Oracle for DML statements, while explicit cursors are defined by the user for queries returning multiple rows. Cursor attributes provide information about the state of the cursor, and a cursor for loop simplifies the handling of cursors by managing opening, fetching, and closing automatically.
