PL/SQL Cursor: Definition, Types & Usage
A cursor in PL/SQL is a data structure used to handle query result sets. It allows developers to process query results row by row, similar to a pointer in a database. Through cursors, developers can loop through query results in PL/SQL code to further manipulate data or perform other operations. Cursors can be explicit or implicit, each with slightly different ways of use. In PL/SQL, cursors are typically used for handling complex queries or situations where results need to be processed row by row.
