RPT-VIDEO -(Hands-On
10) How to use Drill Down or Push Button report
Drill Down or Push Button
Report
Introduction
A drill-down report
lets you get more detailed information at a different level of data
aggregation. The most common methods of drilling-down use the mouse or
a button to call another report, graph, or form.
Hands-on
You client likes what you
did on the previous Hands-On and ask you to use the report on the "Stock
History" report. This should give them an option to get customers
list (Customers List) for each company.
They ask you to create a
drill down report on the company"s stock information so they get
more detailed information about that company"s shares holders. Your
report (Stock History) should have push button to call company"s
shares holder from previous Hands-On (Customers List). The report
should show for the security shown on the screen all customers of that
security, the amount of their position, and the total number of shares
held.
See Figure 10.
Your tasks are:
1- Modify the "Stock
History" report.
2- Add the Push Button
option to call the "Customers List" report.
3- Write a trigger to
execute the "Customers List" report.
4- Run the report using "Runtime
Pre-viewer."
5- Test the report.
F You will learn how
to: use push button to execute another report, use or pass parameter,
use the "select parent frame" icon, use or open objects property,
compile report, use the boilerplate, write and compile PL/SQL trigger,
use "runtime pre-viewer."

Drill-Down Report
A drill-down report
lets you get more detailed information at a different level of data
aggregation. The most common methods of drilling-down use the mouse or
a button to call another report, graph, or form.
Open the Reports Builder
tool.
Open a Report Module
In the "Object Navigator"
window, go to the Main menu and choose "File," select "Open"
to open an existing report (REPT02) from the "iself" folder.
Save a Report Module
Save it as report number 10
(REPT10). You do this to leave the REPT02 module untouched.
Run a report
In the Object Navigator, on
the vertical toolbar, click on the "Run" icon to run the report.
Browse a report
Navigate through the
report. Notice that there are black spaces under the SYMBOL and
COMPANY column. That is a perfect place to add a push button to list
the company's shares holders.
Create a push button
To do that: In the Live
Pre-viewer, click on the "Layout Model" icon. In the "Report
Editor - Layout Model" window, select the company item, and click on
the "Parent Frame" icon until the handlers do not change.
Then drag the handler to make more space to work with.
Once again, click on the
COMPANY item, and click only once on the "Parent Frame"
icon. Then drag the handler as far as the first one.
Click on the Push Button
icon on the vertical toolbar and move the cross cursor to the "Layout
Editor" under the SYMBOL and COMPANY columns and then click and drag
to make a push button on a suitable size.
Right click on it and open
its property. In its property palette, type "Customer's list" on
the text box, change the "Type" item to "PL/SQL" and then
double click on the "PL/SQL trigger" item.
PL/SQL for push button
A Program Unit window will
be opened. In its PL/SQL section, write a PLSQL statement to call the
previous report that was created from the previous hands-on. Use the
binding variable to pass the company symbol as a parameter. Write all
the exception.
(PL/SQL)
PROCEDURE U_1ButtonAction
IS
BEGIN
-- make sure that REPT09
has already been compiled successfully.
srw.run_report ("c:PARAMFORM=NO
SYMBOL="
|| :symbol)
EXCEPTION
WHEN srw.run_report_failure
THEN
srw.message (1002, "Could
not run the Detail Report Customers List");
WHEN others THEN
srw.message (1003, "Unknown
problem, please see your developer.");
END;
Compile the PL/SQL block
Compile the trigger. If the
output is successfully compiled, then close the window.
Close the property palette.
Close the "Layout Model"
window.
Compile a report
Make sure that the REPT09
has already been compiled.
(File > Administration
> Compile file")
Run the new report.
Runtime Pre-viewer
To test the Push Button,
you should use the "Runtime Pre-viewer" option. To use the
"Runtime Pre-viewer" option, go to the Main menu, choose the
"View" sub-menu, select the "Runtime Pre-view"" option, and
the Pre-viewer screen will be appeared. Notice that your Push Button
color was changed.
Now, click on
"Customer's List" to run the report.
Navigate through the report
pages and then click on the Customer's List to see the company's
shares holders.
After the testing was done,
close the windows and save the changes (REPT10).
