Web Reference: This tutorial introduces you to the PL/SQL cursor and how to use it effectively to fetch data from a table. May 17, 2024 · The cursor is used to retrieve data one row at a time from the results set, unlike other SQL commands that operate on all rows at once. Cursors update table records in a singleton or row-by-row manner. A cursor is a pointer to this context area. PL/SQL controls the context area through a cursor. A cursor holds the rows (one or more) returned by a SQL statement. The set of rows the cursor holds is referred to as the active set.
