Using Explicit Cursors Versus Implicit Cursors

A topic that has inspired much debate over the years is the choice between explicit and implicit cursors—or put another way, the “OPEN, FETCH, CLOSE” versus the “SELECT INTO” debate. In this section, I will completely set aside the debate about performance because Oracle has done a lot of work in recent releases to render the point moot. Instead, I’ll focus on the effects on the database and discuss the differing PL/SQL usage of both cursor types including the fact they don’t always match up in the database’s shared pool.
