Q:

What is the difference between creating a thread by extending Thread class and by implementing Runnable interface? Which one should prefer?

Answer

When creating a thread by extending the Thread class, it is not mandatory to override the run method (If we are not overriding the run method , it is useless), because Thread class have already given a default implementation for run method. But if we are implementing Runnable , it is mandatory to override the run method. The preferred way to create a thread is by implementing Runnable interface, because it give loose coupling.

Q:

What are Cursors? Explain Types of cursors in PL/SQL

Answer

Cursors help you manipulate the information retrieved by select statements. This can be done by assigning a name to the cursor.


Example:


CURSOR emp_cur 


IS 


SELECT emp_number from employee_tbl where employee_name = name_in;


Types of Cursors:


Implicit cursors- These cursors are not declared by the programmer. They are issued when the SQL statement is executed. The open, close and fetching is done by itself.


Example:


UPDATE employee SET salary = salary * 2.1;


Here, an implicit cursor is issued to identify the set of rows in the table which would be affected by the update.


 


Explicit cursors- These cursors are defined by programmer. They are used in queries that return multiple rows.


Example:


CURSOR emp_cur 


IS 


SELECT emp_number from employee_tbl where employee_name = name_in;
