<p>
Here's a step-by-step explanation of the above provided PL/SQL code: </p>
<p>
<b>SET SERVEROUTPUT ON:</b> This command enables the display of output in the console. </p>
<p><b>DECLARE:</b>
This keyword signals the start of the declaration section where variables and cursors are defined.
</p>
<p><b>salary Employee.SALARY%type:</b>
This line declares a variable named 'salary' with the same data type as the 'SALARY' column in the 'Employee' table. </p>
<p>
<b>departmentname Employee.DEPT%type:</b> Similarly, this line declares a variable named 'departmentname' with the same data type as the 'DEPT' column in the 'Employee' table. </p>
<p><b>CURSOR sal IS SELECT DEPT, SUM(SALARY) FROM Employee GROUP BY DEPT:</b>
This declares a cursor named 'sal' which retrieves department names and the total salary expenditure for each department from the 'Employee' table.
</p>
<p><b>BEGIN:</b>
This keyword marks the beginning of the executable section of the PL/SQL block. </p>
<p><b>DBMS_OUTPUT.PUT_LINE('Department-wise salary expenditure:'):</b>
This line prints a header indicating that the following output will display department-wise salary expenditure. </p>
<p><b>OPEN sal:</b>
This command opens the cursor 'sal' to start fetching data from it. </p>
<p><b>LOOP:</b>
This keyword starts a loop that iterates through the cursor result set. </p>
<p><b>FETCH sal into departmentname, salary:</b>
This command fetches the next row of data from the cursor 'sal' into the variables 'departmentname' and 'salary'. </p>
<p><b>EXIT WHEN sal%NOTFOUND:</b>
This line checks if there are no more rows to fetch from the cursor 'sal' and exits the loop if true. </p>
<p><b>DBMS_OUTPUT.PUT_LINE(departmentname || ' department, total salary is ' || salary):</b>
This line prints the department name concatenated with the total salary for that department. </p>
<p><b>END LOOP:</b>
This marks the end of the loop. </p>
<p><b>END:</b>
This marks the end of the PL/SQL block. </p>
<p>In summary, this PL/SQL code retrieves department names and their respective total salary expenditures from the 'Employee' table and prints them out in the console, providing users with a clear overview of department-wise salary expenditure.</p>
