Implementing a simple ap-plication with embedded SQLs

CS562 Project #1

Assignment Date : October 11th, 2012Due Date : October 28th, 2012

TA: Lee, Min-Joong

Interactive SQL

SQL queries which you can type in at the SQL prompt.

INTERACTIVE SQL is good for: defining database structure▪ Create database, tables ….

generating low-volume, ad hoc queries prototyping

Embedded SQL

SQL is a ‘non-procedural’ language. INTERACTIVE SQL is not good for the more so-

phisticated applications. SQL can be embedded within procedural

programming languages(host language). Supports

highly customized applications background applications running without user

intervention database manipulation which exceeds the abili-

ties of simple SQL.

HOW to embedding SQL?

USE ESQL - old school style! ESQL/c, ESQL/C++ , ESQL/COBOL ,… ESQL is precompiled by preprocessor.

Use APIs JDBC ADO.NET ODBC …

Embedded SQL

For example, JDBC, java Get names of awards which ‘Winona Ryder ‘

won.…Statement stmt1 = conn.createStatement();Statement stmt2 = conn.createStatement();ResultSet rs1 = stmt1.executeQuery("select actorID from actor where actor name = ‘Winona Ryder ‘ “);while (rs1.next()) { name = rs1.getString(1);} rs1.close();rs1 = stmt1.executeQuery(“select awordID from actorAwarded where actorID = “ + name );while (rs1.next()) { ResultSet rs2 = stmt2.executeQuery(“select awordName from award where awardID = “+ rs.getInt(1) ); System.Out.Println(rs2.getString(1));} rs2.close();

Queries

Translate given statements into SQLs and process the query using your application. Initial data input Insert award data Insert rating data Select statements Update statements Delete statements

Queries

Some queries are should be implemented using an embedded SQL method rather than using a single SQL statement or a trigger.

Unspecified queries can be implemented in any ways.

…4. Select the names of the movies whose actor are dead. (Use embedded SQL method)5. Select the names of the directors who cast the same actor more than once. (Translate this statement to a single SQL statement; do not use embedded SQL method)6. Select the names of the movies and the genres, where movies have the common genre. (Translate this statement to a single SQL statement. Use sub-query SQL)…

Output-Example

Database created!

Table created!

Initial data inserted!

Statement : Winona Ryder won the “Best supporting actor” award in 1994

Translated SQL : INSERT xxxxxxxxxxxx

Updated tables

award table

xxx table

…..

Statement : xxxxx

Translated SQL : xxxx

….

awardID awardName

0000 Best supporting actor

You should show the results for translated inserts/deletes/up-dates queries and all the up-dated tables for each statement.

Before run your application, assume that the database is empty.

Environments

Recommended environments Language : JAVA IDE : Eclipse DBMS : MySQL▪ JDBC download: http://dev.mysql.com/downloads/connector/j/

DBMS setting ▪ Database name : CS562_studentID (ex., CS562_20111234)▪ Root id : root // password : cs562▪ Tables are should be named as I descried in the initial data

table.▪ Database should be installed at localhost(local machine)

If cannot understand above description, read JDBC Introduction.
