Program Plan Intro

SQL:

SQL stands for “Structured Query Language”.

The current version of SQL is “ANSI SQL – 92”.

It contains constructs which are used to define and process database. They are executed using DBMS-supplied command prompt.

SQL is not a programming language. It is text-based and it is also called as data sublanguage. In order to get SQL as a complete programming language, it should be included in scripting languages like Java, C#, and so on.

Display values from table:

The contents from the table can be viewed by using “SELECT” statement which comes under Data Manipulation Language (DML).

The syntax to view the contents using asterisk () is as follows:

SELECT FROM table_Name;

HAVING Clause:

In SQL, “HAVING” clause in used to overcome “WHERE” clause because, “WHERE” clause cannot be used with aggregate functions. It is possible to group limited number of members by using “HAVING” clause.

Syntax:

SELECT column_Name1 FROM table_Name GROUP BY column_Name2 HAVING condition;

1. Create a Person.java file. Implement the public Person and Student classes in Person.java, including all the variables and methods in the UMLS. Person -name: String -street: String -city: String +Person(String name, String, street, String, city) +getName(): String +setName(String name): void +getStreet(): String +setStreet(String street): void +getCity(): String +setCity(String City): void +toString(): String Student -Id: int +Person(String name, String, street, String, city, int Id) +getId(): int +setId(int Id): void +toString(): String 2. Create a StudentTest.java file. Implement a public StudentTest class with a main method. In the main method, create one student object and print the object using System.out.println(). Your printing result must follow the example output: name: Mike, street: Morris Ave, city: Union, Id: 1000 Hint: You need to modify the toString methods in the Student class and Person class!
