how to FETCH STATEMENT CURSOR in oracle database query

FETCH statement in Oracle PLSQL is used to access the records from the CURSOR which has been previously opened.

Oracle PSQL Syntax to use FETCH CURSOR statement is:

FETCH cursor_name INTO ;

Let’s understand, how to use FETCH Statement in a cursor from the help of the below PLSQL function:

CREATE OR REPLACE FUNCTION GetSalary
  IS
  cur_sal NUMBER;

CURSOR cur_salary
IS
  SELECT salary
  FROM employee;

BEGIN
  FETCH STATEMENT cur_salary;
  FETCH cur_salary IN cur_sal;
  IF cur_salary%NOTFOUND THEN
        cur_sal := 100000;
  END IF;

CLOSE cur_salary;
END;

The line FETCH cur_salary IN cur_sal is used to FETCH the records in the cursor.
