Practices for Lesson 3: Interacting with the Database by Using SQL Workshop Chapter 3




Practices Overview There are three practices for this lesson. In these practices, you use the components of SQL Workshop to create and modify tables, upload and run scripts, build and save queries, and load and unload data. Hints in the form of SQL queries have been provided in case you are not familiar with writing SQL queries.



Practice 3-1: Using Object Browser

Overview In this practice, you use the Object Browser to view, create, and modify tables.

Assumptions N/A

Tasks a. Create a table called OEHR_AUDITS with the following details.

Column Name Data Type Other Details

CUSTOMER_ID (PK) NUMBER Not populated

CREATED_BY VARCHAR2 Scale 40

CREATED_ON DATE N/A

c. Create a lookup table for the OEHR_ORDERS table by using the ORDER_MODE column. Follow the following naming convention:

Table name: OEHR_ORDER_MODE_LOOKUP Sequence name: OEHR_ORDER_MODE_LOOKUP_SEQ

What do you think will happen to the data in both tables after the lookup table has been created?

d. Display the data from the OEHR_COUNTRIES table and save the data in a spreadsheet.

e. Change the data type for the JOB_TITLE column in the OEHR_JOBS table to char and the length to 300.



Practice 3-2: Using SQL Commands, SQL Scripts, and Query Builder

Overview In this practice, you use SQL Commands, SQL Scripts, and Query Builder to upload, save, and run queries.

Assumptions You have performed the previous practice.

Tasks a. Using SQL Commands, update the ORDER_DATE column in the OEHR_ORDERS table

by running the following query. UPDATE oehr_orders

SET order_date = order_date + 2290

/home/oracle/labs/scripts folder and name it Create Territory Table. Run the script and confirm that it ran successfully.

c. Upload the get_sal.sql script file from the /home/oracle/labs/scripts folder

and name it Get Salary. Run the script and correct errors, if any.

d. Use the get_sal procedure, created in the previous task, and execute a query that displays the last name, employee ID, and salary for employees. Also include a proposed salary, which should be 40% more than the current salary.

Hint: SELECT last_name, employee_id, salary CURRENT SALARY,

get_sal(employee_id, 1.4) PROPOSED SALARY

FROM oehr_employees;

e. Using Query Builder, create and save a query to retrieve the department ID, name,

city, state, and the country name for each department.



Practice 3-3: Using Utilities

Overview In this practice, you use SQL Workshop Utilities to load/unload data and generate DDL.

Assumptions You have performed the previous practice.

available in the /home/oracle/labs/files folder. The data in the file is stored as comma-separated values (CSV) and the first row in the file contains the column names. Name the table columns STATE_ID and STATE_NAME. Accept the option to create a new primary key and sequence. View the created table in the Object Browser.

b. Unload data from the OEHR_ORDERS table to a CSV file. Ensure that the table column names are also included in the file.

c. Unload data from the OEHR_JOBS table to an XML document adhering to the canonical

XML specification.

d. Generate a DDL script file for the STATES table and sequence. Name the file as states.sql. Download and save the file to the /home/oracle/labs folder.



Practice Solution 3-1: Using Object Browser

Overview In this practice solution, the steps to view, create, and modify tables by using the Object Browser are provided.

Practices for Lesson 5: Creating Reports Chapter 5 - Page 1

Practices for Lesson 5: Creating Reports Chapter 5




Practices Overview There are four practices for this lesson. In these practices, you build and manipulate an interactive report, customize an interactive report, and create a SQL report and a wizard report.



Practice 5-1: Building and Manipulating an Interactive Report

Overview In this practice, you create and manipulate two interactive reports.

Assumptions You have performed the previous practices or imported both LAB03_SOLN.SQL and LAB04_ORDER_MGMT_SOLN.SQL packaged applications.

Tasks a. Create an interactive report region on the Customers page called Customer Report that

displays all the columns from the OEHR_CUSTOMERS table. Perform the following customizations to the report: Create a filter on the city of Philadelphia. Create a highlight where Credit Limit is greater than 2500. Display only the customer name, address, and credit limit. Display only five rows to see how pagination works. Delete the filter that you created previously. Display the rows in ascending order by state. Create a Group By report to display the number of customers in a particular

province or state. Save the report as a private report called My Report. Reset the primary report to its original state. View a single row view.

b. Create an interactive report to display details (employee_id, first_name,

last_name, manager_id, commission_pct), from the OEHR_EMPLOYEES table about who earns a commission. You must make the following customizations to the report: Management proposes to increase the commission to employees whose existing

commission percentage is less than or equal to 0.15. Create a computed column to display the new commission. The new commission scheme includes: Employees with commission percentage of 0.1 will get an additional

commission of 0.1. Employees with commission percentage of 0.15 will get an additional

commission of 0.05. Create a control break on Manager ID. Display the maximum commission earned by employees under each manager. Download the HTML report. Save all the customizations that you have made to this report so that it will be

available to other managers but is not the default report (not just you).



Practice 5-2: Customizing Your Interactive Report

Overview In this practice, you customize the interactive report that you created in the previous practice.


Tasks a. As a developer, you can change the way that the interactive report is rendered for all

users. In this practice, you make the following customizations to the Commissions Report: Hide the EMPLOYEE_ID and change the MANAGER_ID to be the FIRST_NAME

and LAST_NAME of the manager. Remove the Highlight option from the Actions menu. Add XLS and PDF download formats. Remove the Single Row View icon for each row in the report.



Practice 5-3: Creating a SQL Report

Overview In this practice, you create a report by using the SQL Report Wizard.


Tasks a. Create a new page with a SQL report named Top Tier Salary in the Order

Management application. The report should display the last name, email, and salary of employees who earn between $5,000 and $12,000. The report should contain a search bar.



Practice 5-4: Creating a Wizard Report

Overview In this practice, you create a wizard report and edit the attributes of the report. You modify the column names and modify the query definition of the report and specify conditions for the query.


Tasks a. In the Order Management application, create a wizard report on a new page. Name it

Customer Address List. The report displays the address information of your customers, such as the first and last names, address, city and state. Then run the report.

b. Modify the Customer Address List report with the following requirements: Change the report headings for CUST_FIRST_NAME and CUST_LAST_NAME to

First Name and Last Name respectively. Change the Pagination to Row Ranges X to Y of Z (with pagination). Review the query definition and add the OEHR_COUNTRIES.COUNTRY_NAME

column to the report. Note: You will need to create a join.



Practice Solution 5-1: Building and Manipulating an Interactive Report

Overview In this practice, you create and manipulate two interactive reports.

Tasks a. Create an interactive report region on the Customers page called Customer Report that

displays all the columns from the OEHR_CUSTOMERS table. Perform the following customizations to the report: Create a filter on the city of Philadelphia. Create a highlight where Credit Limit is greater than 2500. Display only the customer name, address, and credit limit. Display only five rows to see how pagination works. Delete the filter that you created previously. Display the rows in ascending order by state. Create a Group By report to display the number of customers in a particular

province or state. Save the report as a private report called My Report. Reset the primary report to its original state. View a single row view. 1) Navigate to the Order Management Application Home Page and select the

Customers page.
