Question 1: Create a procedure that accepts 3 parameters, the first two are of mode IN with number as their datatype and the third one is of mode OUT in form of Varchar2. The procedure will compare the first two numbers and output the result as EQUAL, or DIFFERENT. Create a second procedure called L8Q1 that accepts the two sides of a rectangle. The procedure will calculate the area and the perimeter of the rectangle. Use the procedure created previously to display if the shape is a square or a rectangle. The following are the example on how we execute the procedure and the expected output. SQL > exec L4Q1(2,2) The area of a square size 2 by 2 is 4. It`s perimeter is 8. SQL > exec L4Q1(2,3) The area of a rectangle size 2 by 3 is 6. It`s perimeter is 10.
Create a function named 'find_stadium_count' which takes k_city_id as input and returns the stadium_count, i.e., it returns the number of stadiums in the city which its corresponding id as k_city_id. Use the skeleton file, to create the function. Function name: find_stadium_count Input parameter : k_city_id with data type as int. Output parameter : stadium_count with data type as int. Table used : k_venue. when i tried i am getting compilation error plz help me out sir...! please write a function for the given specifications sir?
Can you help me in this Create a pseudo function called pseudo_fun that accepts 2 parameters represented the height and width of a rectangle. The pseudo function should return the area and the perimeter of the rectangle. Create a second procedure called L4Q2 that accepts the two sides of a rectangle. The procedure will use the pseudo function to display the shape, the area and the perimeter. SQL > exec L4Q2(2,2) The area of a square size 2 by 2 is 4. It`s perimeter is 8. SQL > exec L4Q2(2,3) The area of a rectangle size 2 by 3 is 6. It`s perimeter is 10.

can we call functions inside the procedure and can we call procedure inside the function in sql? plz tell me sir.......i need for 2 examples regarding above problems
Yes , we are able to call function inside the procedure, but no idea about calling procedure inside the function . I had implemented it in our company.

3 is
4 RESULT NUMBER(10);
