Benefits of Productivity Features

In order to meet competition, avoid obsolescence, and seize opportunities, a business must beable to:

• Respond rapidly to new or changing information needs.

• Produce applications that end users can learn quickly.

• Develop and maintain applications at reasonable cost.

Reports Developer provides many features that help new developers become productive rightaway. Experienced developers benefit from these features too.

Visual Design

Advancing computer technology has placed enormous power on desktops. Reports Developeruses this power to let you work the way you think.

• Object navigators

• Layout editors and previewers.


8/98



Object navigators:

Object navigators give you the "big picture" of your projects, reports, charts, and databaseitems. An outline format lets you expand or collapse individual areas.

Layout editors and previewers:

Layout editors and previewers show you what your designs look like as you make them.


9/98



Wizards

Wizards help you build reports and charts by asking you for all the basic information needed in aneasy-to-understand format. You can then use these components as they are or customize them.You can also use some wizards to change existing components.

Templates

A template is a report or chart that you can use as a starting point for your own applications. Theapplications you create from a template inherit the template's characteristics.

Templates promote a consistent look and feel by assuring that all items of a given kind start fromthe same point.

Data model

Data Definition objects in data model:

Queries:

A query contains a SQL SELECT statement that retrieves data from the databasefor your report.

Non-linkable queries:

A non-linkable query is a detail query that contains column objects that prevent

the query from being linked to via a column-to-column link. If you attempt tocreate such a link, a message dialog box displays, which prompts you to choose

whether to create a group-to-group query (using the parent groups), or to cancel

the operation. A non-linkable query displays in its title bar.

Instead, you can create a group-to-group link between the two queries and add a

WHERE clause to the child query’s SELECT statement, using a bind variable toreference the parent column.

Groups:

Groups are created to organize the columns in your report. When you create aquery, Report Builder automatically creates a group that contains the columns

selected by the query. You create additional groups to produce break levels in the

report, either manually or by using the Report Wizard to create a group above or

group left report.


11/98



Columns:

Database columns:

A database column represents a column that is selected by the query. For eachcolumn that you select in your query, Report Builder automatically creates a

column in the data model of your report.

Formula columns:

A formula column performs a user-defined computation on another column(s)data, including placeholder columns.

Formula columns should not be used to set values for parameters.


12/98



Report Level

Group Level

Placeholder columns:A placeholder is a column for which you set the datatype and value in PL/SQL

that you define. You can set the value of a placeholder column in the followingplaces:

* The Before Report Trigger, if the placeholder is a report-level column

* A report-level formula column, if the placeholder is a report-level column

* A formula in the placeholder's group or a group below it (the value is set once

for each record of the group)

sort columns:

A sort column is used in an Express Report to sort Express dimension values. For

each dimension selected in the Express query, Report Builder automaticallyinserts a corresponding sort column in the data model of your report. A sort

column contains the Express index to the corresponding dimension value.

Summary columns:A summary column performs a computation on another column's data. Using the

Report Wizard or Data Wizard, you can create the following summaries: sum,average, count, minimum, maximum, % total. You can also create a summary

column manually in the Data Model view, and use the Property Palette to create

the following additional summaries: first, last, standard deviation, variance.


13/98



Note: For group reports, the Report Wizard and Data Wizard create n summaryfields in the data model for each summary column you define: one at each group

level above the column being summarized, and one at the report level. For

example, if a report is grouped by division, and further grouped by department,

then a summary column defined for a salary total would create fields for the sumof salaries for each division and each department group (group-level summaries),

and the sum of all salaries (report-level summary).

Report Level

Group Level

Parameters:

Referencing columns and parameters:

You can reference user parameters, system parameters and columns as either bindreferences or lexical references .

Bind references:

Bind references (or bind variables) are used to replace a single value in SQL or

PL/SQL, such as a character string, number, or date. Specifically, bind referencesmay be used to replace expressions in SELECT, WHERE, GROUP BY, ORDER

BY, HAVING, CONNECT BY, and START WITH clauses of queries. Bind

references may not be referenced in FROM clauses or in place of reserved wordsor clauses.

You create a bind reference by entering a colon (:) followed immediately by the

column or parameter name. If you do not create a column or parameter beforemaking a bind reference to it in a SELECT statement, Report Builder will create a

parameter for you by default.

Eg: SELECT ORDID, TOTAL FROM ORD WHERE CUSTID = :CUST

SELECT NVL(COMMPLAN, :DFLTCOMM) COMMPLAN,

SUM(TOTAL) TOTAL FROM ORD GROUP BY NVL(COMMPLAN,:DFLTCOMM)


14/98



Lexical references:

Lexical references are placeholders for text that you embed in a SELECT

statement. You can use lexical references to replace the clauses appearing after

SELECT, FROM, WHERE, GROUP BY, ORDER BY, HAVING, CONNECT

BY, and START WITH.

You cannot make lexical references in a PL/SQL statement. You can, however,use a bind reference in PL/SQL to set the value of a parameter that is then

referenced lexically in SQL. Look at the example below.

You create a lexical reference by entering an ampersand (&) followed

immediately by the column or parameter name. A default definition is not

provided for lexical references. Therefore, you must do the following:

Before you create your query, define a column or parameter in the data model for

each lexical reference in the query. For columns, you must enter Value if Null,and, for parameters, you must enter Initial Value. Report Builder uses thesevalues to validate a query with a lexical reference.

Eg:SELECT &P_ENAME NAME, &P_EMPNO ENO, &P_JOB ROLE FROM

EMP

P_ENAME, P_EMPNO, and P_JOB can be used to change the columns selectedat runtime. For example, you could enter DEPTNO as the value for P_EMPNO

on the Runtime Parameter Form. Note that in this case, you should use aliases for

your columns. Otherwise, if you change the columns selected at runtime, thecolumn names in the SELECT list will not match the Report Builder columns and

the report will not run


15/98



Data links:

Data links relate the results of multiple queries. A data link (or parent-child

relationship) causes the child query to be executed once for each instance of its

parent group. When you create a data link in the Data Model view of your report,

Report Builder constructs a clause (as specified in the link's Property Palette) thatwill be added to the child query's SELECT statement at runtime. You can view

the SELECT statements for the individual parent and child queries in the Builder,but can not view the SELECT statement that includes the clause created by the

data link you define.

Note:

Oracle Reports does not support data links between queries that contain column

objects. If you attempt to create such a link, a message dialog box displays,

which enables you to choose whether to tell Reports to create a group-to-groupquery instead (using the parent groups), or to cancel the operation. If you want to

create a link between any type of column and a column object, you can manuallytype the SQL statement using the appropriate column alias(es).


16/98



Layout Model

Layout Objects in reports:

Frames:Frames are used to surround other objects and protect them from being

overwritten or pushed by other objects. For example, a frame might be used tosurround all objects owned by a group, to surround column headings, or to

surround summaries.

When you default the layout for a report, Report Builder creates frames aroundreport objects as needed; you can also create a frame manually in the Layout

Model view.

Note:

Frame name always starts with ‘M_’.

Repeating frames:Repeating frames surround all of the fields that are created for a group’s columns.

The repeating frame prints (is fired) once for each record of the group.When you default the layout for a report, Report Builder creates repeating frames

around fields as needed; you can also create a repeating frame manually in theLayout Model view.

For your understanding, consider there are more than 50 records in a table. Now

when you have only the frame you can display only one record.


17/98



Note:

Repeating Frame name always starts with ‘R_’.

Define repeating frame inside main frame.

For eg:

Without repeating frame:

Sno. Name Empid Dept1 Dinesh 56971 GE

With repeating frame:

Sno. Name Empid Dept

1 Dinesh 56971 GE

.

.

50 Vishnu 56973 GE


18/98



Fields:

A field is the layout container for each column in the layout. A field is owned bythe object surrounding it, typically a repeating frame, unless the field is a

summary (in which case it is owned by a frame).

Parameter Form field:

Parameter Form fields are layout containers for parameters used on the RuntimeParameter Form.

Boilerplate:Boilerplate is any text or graphics that appear in a report every time it is run.

Report Builder will create one boilerplate object for each label selected in the

Report Wizard (it is named B_Column name). Also, one boilerplate object is sometimes created for each report

summary. A boilerplate object is owned by the object surrounding it, unless

otherwise noted.


19/98



Anchors:

Anchors are used to determine the vertical and horizontal positioning of a childobject relative to its parent. The end of the anchor with a symbol on it is attached

to the parent object.

Since the size of some layout objects may change when the report runs (and data

is actually fetched), you need anchors to define where you want objects to appear

relative to one another. An anchor defines the relative position of an object to theobject to which it is anchored. Positioning is based on the size of the objects after

the data has been fetched rather than on their size in the editor. It should also be

noted that the position of the object in the Layout editor effects the final position

in the report output. Any physical offset in the layout is incorporated into thepercentage position specified in the Anchor property sheet.

Anchor restrictions:

• An object may be anchored to only one other object.

• Matrix objects, anchors, and the margin cannot be anchored to anything (i.e., theymay not be the parent or child object for an anchor).

• A repeating frame that is the vertical or horizontal repeating frame for a matrixcannot be anchored to another object, but other objects may be anchored to it (i.e.,it can be the parent but not the child object for an anchor).

• Nothing can be anchored to a hidden object (an object with Visible set to No).

• Moving an anchor also causes the two objects it anchors together to move.

• Objects cannot be anchored together in such a way that they have a circulardependency.

• To copy an anchor, you must select the anchor and the two objects it anchorstogether. If you select the anchor by itself, nothing will be copied to the paste

buffer. If you select the anchor and one of the objects, only the object is placed inthe clipboard.


20/98



• An anchor cannot be resized.

• An anchor must always be on top of the objects it anchors together (i.e., it must beone or more layers above the parent and child objects). Report Builder prevents

you from moving the anchor to a layer below its parent and child objects.

• You cannot use Align, Align Objects, or Size Objects from the Arrange menu onanchors.

Examples:

Centering fields horizontally Centering fields vertically

Collapse Vertically and Horizontally

Collapse Vertically example Keep With Anchoring Object


21/98



Parameter Form

The Report Editor's Parameter Form view enables you to create a Runtime ParameterForm for your report. You can select pre-defined system parameters for your form using

the Parameter Form Builder, or you can create your own.

Painting region

The painting region is the area in which you can create, modify, position, ordelete objects while viewing their graphical representations on the screen.

The painting region of the Parameter Form view is comprised of physicalpages(contains Boiler Plate, fields, graphics).

You specify the size of each parameter form page and the number of pages using

the Report property sheet (double-click the report's node in the Object Navigator).


22/98



Property Palette

The Property Palette has an outline-style interface that enables you to view, locate, and

set object properties. The Property Palette features:

expandable and collapsible nodes

In-place property editing

Summary Column (Report Level)

Reset At

The Reset At property is the group at which the summary column value resets to zero (if

Function is Count), null (if Function is not Count), or Value If Null (if the column hasone). Reset At has a list of values containing valid reset groups. Reset At determines ifthe summary is a running summary or a periodic (e.g., group-level) summary.

Values

Page Is used for page-level summaries. The summary is resetbetween pages

Report Is used for summaries that apply to the entire report, such asgrand totals. The summary is reset after the report (i.e., it is

never reset).

Is a valid group name. The summary is reset after eachrecord of the group.

Applies to summary columns.

• The reset group of a summary column may be its group or any group above itsgroup, including Report and Page.

• To ensure that page summaries behave in a predictable way, make sure eachrecord fits on a single page, or if that is not feasible, force each new record to

print on a new page.

Reset At - Restrictions

Reset At is only editable for summary columns.

Summary columns that are owned by a cross-product group cannot have a ResetAt of Page.

If a summary has a Reset At of Page, then the sizing of the field or boilerplateobject that displays it must be fixed.

If a column has a Reset At of Page, then any fields that use it as a source must becontained in repeating frames that use the column's group as their source.

A Reset At of Page will not work for reports that have multiple repeating framesassociated with a group that is involved in the summary. One common case ofthis is a matrix report. As a result, matrix reports cannot have page-level

summaries.


41/98



For multiple summary columns that are in child groups that share the same parentgroup, a Reset At of Page may produce incorrect results.

If your data model contains multiple child groups with a shared parent (e.g.,

master-detail-detail), summary columns with a Reset At of Page may giveunexpected results.

Steps

Consider the tabular report above. Follow the steps 1 to step 3 in above example.

Step 4: In data model click for creating summary column.

Step 5: Right click summary column ”CS_1” for property palette.


42/98



Step 6: In property palette you can see the column type is “summary” and the default

data type is “Number”.

Now select the “function” as your choice such as sum, count, max, min etc.


43/98



Step 7: Now go to “Layout Model”. There create a field F_3 go to its property palette

and assign source as CS_1 as below.

Step 8: Run the report.

Step 6: Now go to Layout model create a field “F_4” inside Main frame and go to its

property palette and set its source as “CS_


46/98



Step 7: Now run the report.


47/98



Conditional Formatting

Using the Conditional Formatting and Format Exception dialog boxes, you can specifyoutput formatting attributes (font and/or color) for a selected layout object based on

conditions that exist. The conditions that you define are called format exceptions.

You can display the Conditional Formatting dialog box from the Live Previewer view or

Layout Model view in any of the following ways:

Double-click the object to display the Property Palette. Under the General Layoutnode, click the Conditional Formatting value field (labeled ¼).

Display the pop-up menu (right-click in Windows) for the object.

Click the object, then choose Format Conditional Formatting.

After you specify conditions and formatting for the current layout object in the Format

Exception dialog box, the entire definition is exported to a PL/SQL format trigger. If a

format trigger already exists for the layout object, the definition in the Format Exceptiondialog box overwrites the existing trigger code when you confirm the Report Builder

prompt.

You can edit the format trigger manually via the PL/SQL Editor; however, if you

subsequently modify the definition using the Format Exception dialog box, Report

Builder displays a prompt to overwrite the existing format trigger.

Consider the above report for demo.

Step 1 to step 6 is same as above.


48/98



Step 7: Go to “Layout Model” right click any object in the report, click “conditional

Formatting”.

\


49/98



Now set the condition and format as per your wish.

Set condition for COST_PRICE field also. Then run the report.

Formula Column (Report Level)

Now create report manually using normal steps.

Step 3: In data model

Now click this icon for creating a formula column. Then click the report.

Query:

select product_no,qty_on_hand,cost_price from product_master


51/98



Step 4: Now create Formula column by pressing this icon . Then right click “CF_1”,

click property palette.

Click the “PL/SQL Formula” tab. Write the following code in the function.

Then Press “Compile” button to check code is write or not. If sucessfully completedClose the window.

Note:

While reteriving the value from any layout object put “:” in front of object name.

Code: return :CS_1 * 0.125;


52/98



Step 5: Noe create a layout in layout model.

Formula Column (Group Level)

Step 1: Create the report in usual manner.

Step 2: Now go to data model for creating summary and formula column.

Step 3: Now select the group and click Formula column icon .

Query:

select product_no,qty_on_hand,cost_price from product_master


54/98



Right click “CF_1” and click property palette. Then click “PLSQL Formula” tab.

Then in the PLSQL editor write the following code.

Step 4: In the same way create a summary column at report level.

Code: return (:qty_on_hand)*(:cost_price);


55/98



Step 5: Now create one more formula column at report level.

Step 6: Move to Layout model to create layout for objects.

Code: return :CS_1 * 0.125;


56/98

Parameter Form (Bind Reference)


As we have used bind reference in the query, automatically the “User Parameter” iscreated.

Query:select * from SALES_ORDER_DETAILS

where product_no = :PRODUCT_NUM


62/98



Step 2: Now go to the parameter form. Then create a field using this icon .

Then right click the field and go to its property palette.

Now select the source as “PRODUCT_NUM”. You can think why product_num. This isbecause it is the bind reference used in SQL “SELECT Statement” in QUERY.


63/98



Step 3: Now go to “layout model” to create a layout for the report as below.



64/98



Now select the product number as your choice.


65/98



After selecting press “Enter”.

Sample Output 2:

Sample Output 3:


66/98



Query:

select * from sales_order

Break Report (Without Joins)

Break report is created when you want the repeating values for the column to be printedonly once.

Thus the break report are efficient only when the select statement includes a column,called a break column containing at least one value which repeats over multiple records.

Step1: create the report in usual manner.

Step 2: Now click the “ORDER_STATUS” from the group “G_S_ORDER_NO” anddrag it above the group as below.


67/98



Step 3: Now go to the layout model & create a layout for this report.


68/98





69/98



Query:

SELECT sales_order.s_order_no,sales_order.dely_date,

sales_order_details.product_no,

product_master.description,product_master.unit_measure,

sales_order_details.qty_ordered,

sales_order_details.qty_disp

FROM sales_order,sales_order_details,

product_master

WHERE sales_order_details.s_order_no = sales_order.s_order_no AND

sales_order_details.product_no = product_master.product_no ANDsales_order_details.qty_ordered > sales_order_details.qty_disp

Break Report (With Joins)

Create the report in usual manner. Create a break group “G_1” which has columns

“S_Order_no” & “Dely_date”


70/98



Now create a layout as shown below.

Then run the report.


71/98



Master-Detail Report

A simple Master-detail report contains two group Master group & detail group.

For each master record fetched, relative detail records are fetched. Therefore its verysimilar to break report.

If you use default tabular layout the master-detail report will look like break report.

Concept:

Break & master-detail report can result in similar outputs but they requiredifferent data model objects.

Break report uses one query and two or more groups.

Master-detail report contains two queries each of which has at least one group.

Relationship between two objects is established by using data link(outer join).

Query with Primary key column is called Parent query.

Query with foreign key column is called Child Query.

Layout:

Master-detail report uses default master detail layout in which master records aredisplayed across the page with the labels to the left of the group field.

Detail records appear below the master record in standard tabular format.

Matrix Report

A matrix report is a summary report that presents the desire data with headings across the top and down left side.

The data in middle like spreadsheet.

The totals are displayed across the bottom and right side.

A matrix report is referred as “Cross Tab” report.

A matrix report is cross tabulation of 4 set of data:

1. one set across the page.

2. one set of data down the page.3. one set of data is cross product.4. one set of data is filler.

Different types of matrix report.

a. Simple matrix.

b. Nested matrix.c. Multi query matrix with break.d. Matrix break.


80/98



Matrix Data Model

1. Number of queries:Matrix report requires 4 groups with any no. of queries.

If you build report with one query you need at least 3 groups.If you build with multiple queries you need at least 1 group.

2. Group Structure: Matrix reports are built with 4 or more groups:

a. Two or more dimension groups:It’s a cross product group. The information in this group is sometimes

referred as “Matrix Labels”.

b. One or more Cross Product group:

The cross product group contains all possible combination values of thedimension group. This group is represented as intersection of repeatingframes of down & across dimension group.

c. One cell or filler group:The cell group contains actual information that is represented in the cells

of cross product. For each interception of dimension group the cell values

contain zero, one or multiple values.

Summary Column:

While creating the summary column you need to indicate the following:

a. The frequency of summary i.e. the dimension group to which it belongs.b. The order n which to compute i.e. top to bottom or left o right.

Matrix Layout:

Matrix layout model should consists of following layout objects:

1. At least 2 repeating frame one with print direction down & another with across.2. A matrix object created for cross product group.3. Boilerplates for each column & row of values as well as for summaries.

Matrix / Cross Product Object:

A matrix object defines the intersection of two repeating frames. To create a matrix

object press the following .

Query:

SELECT product_master.description,

sum(sales_order_details.qty_ordered) "quantity",to_char(sales_order.s_order_date,'mm') mth,

to_char(sales_order.s_order_date,'mon') mthfull

FROM sales_order_details,

sales_order,product_master

WHERE (sales_order_details.s_order_no = sales_order.s_order_no) AND

(sales_order_details.product_no = product_master.product_no)GROUP BY to_char(sales_order.s_order_date,'mm'),

product_master.description,

to_char(sales_order.s_order_date,'mon')

ORDER BY to_char(sales_order.s_order_date,'mm')asc

Matrix Report (Using Wizard)

Step 1: Create a query in usual manner in data model.


83/98



Step 2: Now select the “description” in G_description and drag that column to upper

left.

Step 3: Similarly select “mthfull” from the group G_description and drag that to upper

right.


84/98



Now rename the group as follows:

G_description as G-quantity

G_1 as G_description

Step 4: Now click the following icon to create a cross product group and name thatas G_countquantity.

Click the icon and select the groups G_description & G_mthfull.

Rename G_2 as G_count_quantity.


85/98



Step 5: Now create a group level summary column countquantity.

Set the properties to following:

Product order: G_description G_mthfull (Since this is a filler cell).

Function : CountSource : quantity

Reset At : G_mthfull (Since we are restricting the count of quantity every month)


86/98




Product order: G_description

Function : SumSource : Countquantity

Reset At : G_description (Since we need to sum singly item qty for all month)


87/98




Product order: G_mthfullFunction : Sum

Source : Countquantity

Reset At : G_mthfull (Since we need to sum all item qty for all month)


88/98



Step 6: Now create a layout using report wizard.

Query:

SELECT product_master.description,sum(sales_order_details.qty_ordered) "quantity",

to_char(sales_order.s_order_date,'mm') mth,

to_char(sales_order.s_order_date,'mon') mthfullFROM sales_order_details,

sales_order,

product_masterWHERE (sales_order_details.s_order_no = sales_order.s_order_no) AND

(sales_order_details.product_no = product_master.product_no)

GROUP BY to_char(sales_order.s_order_date,'mm'),product_master.description,

to_char(sales_order.s_order_date,'mon')

ORDER BY to_char(sales_order.s_order_date,'mm')asc

Matrix Report (Using Wizard)

Create the report as per above example. Steps 1 to step 5 are same as above.

For differentiating I have changed the names of Groups as follows:

Countquantity as filler cell

Sumcountquantityperdescription as qty_on_hand_all_months Sumcountquantitypermthfull as qty_per_months


94/98



Step 6: Draw a layout for the matrix report in layout model.
