INFO 2303   Database Programming Assignment # : PL/SQL Procedure & Function Practice   Note: PL/SQL can be executed in SQL*Plus or SQL Developer or Oracle Live SQL.   Write a script to create a PL/SQL procedure called findSal that displays the doctor’s salary and bonus after passing in the doc_id into the procedure. For example, if you pass in doc_id 504, you will get the following output.   execute findSal(504)   The salary for Dr.Cotner (504) is: 11500 The bonus is: 7500     PL/SQL procedure successfully completed.

Develop a two small PL/SQL programs. 1. Enter students ID from the keyboard. The program then finds student's first name, last name and phone, stores them in variables and prints them on the screen. 2. Similar to the above, only this time the program will receive student's first name only (instead of student's ID)Then program finds full name and address and prints it on the screen. 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.

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

Which of the following is not a valid SQL statement? (refer to the tables in the JustLee Books database.)a. SELECT MIN(pubdate)FROM booksGROUP BY categoryHAVING pubid = 4;b. SELECT MIN(pubdate)FROM booksWHERE category = 'COOKING';c. SELECT COUNT(*)FROM ordersWHERE customer# = 1005;d. SELECT MAX(COUNT(customer#))FROM ordersGROUP BY customer#;

A. If you are at the SQL prompt, use !filename to open a file called filename and execute the commands inside the file.   TRUE OR FALSE  B. If you use an ORDER BY clause, it must always be the last clause in the SQL Query statement.  TRUE OR FALSE   C. If you want to create a Cartesian product, simply do not join the tables in an SQL query statement.  TRUE OR FALSE

Refer the image and write a sql program as per the question. Don't create any database. Please start your code directly with Select option. The sql program should run on Mysql. An upvote for correct sql program. Just type the correct sql code.

T-SQL procedure for MICROSOFT SQL SERVER   A: obtain the name and credit limit of the customer whose number currently is stored in I_CUSTOMER_NUM. Place these values in the variables I_CUSTOMER_NAME and I_CREDIT_LIMIT, respectively. Output the content of I_CUSTOMER_NAME and I_CREDIT_LIMIT.   HINT use cursor instructions as a template for the problem. Instructions goes as follows CREATE PROCEDURE usp_DISP_REP_CUST @repnum char(2) AS DECLARE@custnum char(3) DECLARE@custname char(35) DECLARE mycursor CURSOR READ_ONLY   FOR SELECT CUSTOMER_NUM, CUSTOMER_NAME FROM CUSTOMER WHERE REP_NUM = @repnum   OPEN mycursor FETCH NEXT FROM mycursor INTO @custnum, @custname   WHILE @@FETCH_STATUS=0 BEGIN PRINT@custnum+' '+@custname   FETCH NEXT FROM mycursor INTO @custnum, @custname END CLOSE mycursor DEALLOCATE mycursor
