Laboratory Exercise Working With OLAP Operations

Objectives

At the end of this exercise, the students are expected to:

Apply the CUBE operation

Apply the GROUPING SETS operation

Apply ROLLUP operation

Computer Terminal

Software installed on the terminal: Sybase SQL Anywhere 9 Opening documents/reading – i.e. MS

Word, Acrobat Reader, etc.

Printer and Paper (as necessary)

Activity 1 Creating and Populating the Table

1. Open Sybase Central. 2. Create a new database and name it "ADDBASE_LAB4". 3. Using the Sybase Central, create the table Employee. The table structure is described

below:

ID VARCHAR(4) NOT NULL,

First_Name VARCHAR(10),

Last_Name VARCHAR(10),

Start_Date DATE,

End_Date DATE,

Salary Integer,

City VARCHAR(10),

Description VARCHAR(15)

4. Using the Interactive SQL, populate the Employee table. The sample values are listed below.

ID FIRST_NAME LAST_NAME START_DATE END_DATE SALARY CITY DESCRIPTION

02 Alison Abalos 21-MAR-76 21-FEB-86 6661.78 Makati Tester

03 James Bartolome 12-DEC-78 15-MAR-90 6544.78 QC Tester

04 Celia Lopez 24-OCT-82 21-APR-99 2344.78 QC Manager

05 Robert San Miguel 15-JAN-84 08-AUG-98 2334.78 Makati Tester

06 Linda Liu 30-JUL-87 04-JAN-96 4322.78 Manila Tester

07 David Dolde 31-DEC-90 12-FEB-98 7897.78 Manila Manager

08 Lebron James 17-SEP-96 15-APR-02 1232.78 QC Tester

Activity 2 Using the ROLLUP Operation

1. Interactive SQL, type the code below and execute.

SELECT

city, description, SUM(salary),

RANK() OVER (ORDER BY SUM(salary) DESC) AS rank

FROM employee

GROUP BY ROLLUP(city)

ORDER BY city, description;

2. List the output and explain the output of the operation.

Activity 3 Using the CUBE Operation

1. Using the Interactive SQL, type the code below.

SELECT city, SUM(salary)

FROM employee

GROUP BY CUBE(city);

2. List the output and explain the output of the operation.

3. Use CUBE and RANK() to get all rankings of salaries by city and description. You may refer to

Step 1 of ROLLUP Operation. 4. List the output and explain the output of the operation.

5. Modify Step 1 to include the description column in the CUBE function. 6. List the output and explain the output of the operation.

Activity 4 Using the GROUPING SETS Operation

1. Using the Interactive SQL, type the code below.

SELECT city, description, SUM(salary)

FROM employee

GROUP BY GROUPING SETS(city, description);

2. List the output and explain the output of the operation.
