There are two main types of cursors in pl sql: implicit cursors and explicit cursors. understanding the difference between these two types is fundamental for efficient pl sql. Let's take a look at the different ways you can define and use cursors (pointers to sql result sets) in pl sql, including: implicit cursor, explicit cursor, cursor expressions, cursor variables,. Pl sql supports implicit and explicit cursors. implicit cursors are created automatically for single‑row dml and queries, while explicit cursors give you full control: you can define, open, fetch, and close them. Let’s extend the previous example by demonstrating the difference between a normal cursor and a reference cursor, along with a scenario where the reference cursor solves a problem that the normal cursor cannot.
