Where shouId I put the while loop in these programs thanks? Develop a two small PL/SQL programs. 1. Enter instructor ID from the keyboard. The program then finds instrutor's first name, last name and phone, stores them in variables and prints them on the screen. USE WHILE LOOP to print all instructors while selecting them one by one in the loop. 2. Similar to the above, only this time the program will receive student's first name only (instead of ID)Then program finds full name and address and prints it on the screen  (work with STUDENT table here) For both programs please implement NO_DATA_FOUND and TOO_MANY_ROWS exceptions. (please refer to chapter 8 in PL/SQL by Example book)For number 2 program, display a message "Possibly you have two or more students with the first name ...." in TOO_MANY_ROWS exception block. 1* select table_name from user_tablesSQL> desc studentName Null? Type----------------------------------------- -------- ----------------------------STUDENT_ID NOT NULL…

Assume that you have a product code that has the following format: XXXXNNN  Where X is a character and N is a digit. Notice that the length of the character part is not fixed, it may range from 2 to 4 characters, while the length of the second part may range from 2 to 3 digits but the first digit from the left is always 0 (zero).     Write a PL/SQL program to separate the code into its two parts as shown in the following example: if the input is ABC031, the output should be:    Product Name is: ABC  Serial Number is: 031
