- Program should follow in term (Contacts Database) Study the books.sql script provided in the ch17 examples folder's sql subfolder. Save the script as addressbook.sql and modify it to create a single table named contacts. The table should contain an auto-incremented id column and text columns for a person's first name, last name and phone number. make a Python script demonstrating: 1. insert contacts into the database, 2. query the database to list all the contacts and contacts with specific last name, 3. update a contact and 4. delete a contact. books.sql code: import panda as pdimport sqlite3connection = sqlite3.connect('books.db')pd.options.display.max_columns = 10pd.read_sql("SELECT * FROM authors",connection) df = pd.read_sql( "SELECT * FROM authors",connection)DROP TABLE IF EXISTS author_ISBN;DROP TABLE IF EXISTS titles;DROP TABLE IF EXISTS authors;CREATE TABLE authors ( id INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT, first TEXT NOT NULL, last TEXT NOT NULL);CREATE TABLE…{ String str = tf5.getInt("ID"); Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); Connection con = DriverManager.getConnection("jdbc:sqlserver://NOMBUSO1806:1433;databaseName= Employee ATM", "NOMBUSO1806", "mysql1234"); // write your database username and password PreparedStatement st = con.prepareStatement("select * from Employees where ID=?"); // Search with ATM ID st.setString(1, str); ResultSet rs = st.executeQuery(); // Excuting Query if (rs.next()) { String s = rs.getString(1); String s1 = rs.getString(2); String s2 = rs.getString(3); // Sets Records in TextFields. tf1.setText(s); tf2.setText(s1); tf3.setText(s2); my getInt() is throwing an error that the method is not found. what should i do?(PL/SQL) the command need to work on Oracle. just post the command and I will check it in my Oracle.

- SQL Commands Tables sec0410_data2 and sec0410_data1 have the same record structure. Each row has three columns: a number column, a text column, and a date column. Write an insert statement that puts all the rows of table sec0410_data2 into table sec0410_data1. So the answer is something like... insert into sec0410_data1 select 'ARR', number, text, date, null, nullfrom sec0410_data2 But all I get is an error message.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.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
