Note that the cursor attributes used to determine cursor state of static cursors can also be used with cursor variables.See Section 4.8.6 for details on cursor attributes.Whereas hard parsing is a resource intensive operation, soft parse, although less expensive, also incurs some cost, as the server process has to search the library cache for previously parsed SQL, which requires the use of the library cache and shared pool latches.Latches can often become points of contention for busy OLTP systems, thereby affecting response time and scalability.When a SQL statement is issued, the server process, after checking its syntax and semantics, searches the library cache for an existing cursor for the SQL statement.If a cursor does not already exist, a new cursor is created (hard parse), else existing cursor is used (soft parse).References: Oracle Core: Essential Internals for DBAs and Developers by Jonathan Lewis P11_QUESTION_ID:865497961356  " target="_blank" rel=" noopener"

To enable caching of session cursors, a positive integer value must be assigned to the initialization parameter SESSION_CACHED_CURSORS, which specifies the maximum number of session cursors to cache.Exception handlers contain code that is called when the exception is raised, either as a predefined PL/SQL exception (such as DECLARE Last_name VARCHAR2(10); Cursor c1 IS SELECT last_name FROM employees WHERE department_id = 20; BEGIN OPEN c1; LOOP FETCH c1 INTO Last_name; EXIT WHEN c1%NOTFOUND; DBMS_OUTPUT.PUT_LINE(Last_name); END LOOP; END; / Exceptions let you handle Oracle Database error conditions within PL/SQL program logic.The result set is fetched using this cursor variable and then it is closed.PL/SQL is a modern, block-structured programming language.
