Benefits of Productivity Features

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

• Respond rapidly to new or changing information needs.

• Produce applications that end users can learn quickly.

• Develop and maintain applications at reas onable 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 desk tops. Reports Developeruses this power to let you work the way you think.

• Object navigators

• Layout editors and prev iewers.


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 des igns look like as you make them.


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 preventthe query from being linked to via a column-to-column link. If you attempt tocreate such a link, a message dialo g box displays, which prompts you to choosewhether to create a group-to-group quer y (using the parent groups), or to cancelthe 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 aWHERE 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 columnsselected by the query. You create additional groups to produce br eak levels in thereport, either manually or by using the Report Wizard to create a group above orgroup left report.


Columns:

Database columns:A database column represents a column that is selected b y the query. For eachcolumn that you select in your qu ery, Report Builder automatically creates acolumn 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.


Report Level

Group Level

Placeholder columns:A placeholder is a column for which you set the datatyp e and value in PL/SQLthat 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 oncefor each record of the group)

sort columns: A sort column is used in an Express Report to sort Express dimension values. Foreach dimension selected in the Express query, Report Builder automaticallyinserts a corresponding sort column in the data model of your report. A sortcolumn contains the Express index to the corresponding dimension value.

Summary columns: A summary column performs a computation on another column's data. Using theReport Wizard or Data Wizard, you can create the following summaries: sum,average, count, minimum, maximum, % total. You can also create a summarycolumn manually in the Data Model view, and use the Property Palette to createthe following additional summaries: first, last, standard deviation, variance.


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 grouplevel above the column being summarized, and one at the report level. Forexample, 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 th e 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

Para meters:

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 rep lace a single value in SQL orPL/SQL, such as a character string, number, or date. Specifically, bind referencesmay be used to replace expressions in SELECT, WHERE, GROUP BY, ORDERBY, HAVING, CONNECT BY, and START WITH clauses of queries. Bindreferences may not be r eferenced in FROM clauses or in place of reserved wordsor clauses.

You create a bind reference b y entering a colon (:) followed immediately by thecolumn or parameter name. If you do not cr eate a column or parameter beforemaking a bind referen ce to it in a SELECT statement, Report Builder will create aparameter for you by default.

Eg: SELECT ORDID, TOTAL FROM ORD WHERE CUSTID = :CUSTSELECT NVL(COMMPLAN, :DFLTCOMM) COMMPLAN,SUM(TOTAL) TOTAL FROM ORD GROUP BY NVL(COMMPLAN,:DFLTCOMM)


Lexical references:

Lex ical references ar e placeholders for text that you embed in a SELECTstatement. You can use lexical references to replace the clauses appearing afterSELECT, FROM, WHERE, GROUP BY, ORDER BY, HAVING, CONNECTBY, 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 thenreferenced lexically in SQL. Look at the example below.

You create a lexical reference by enterin g an ampersand (&) followedimmediately by the column or parameter name. A default definition is notprovided for lexical references. Therefore, you must do the following:

Before you create your query, define a column or parameter in the data model foreach lex ical refer ence 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 FROMEMP

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_EMPNOon the Runtime Parameter Form. Note that in this case, you should use aliases foryour columns. Otherwise, if you change the columns selected at runtime, thecolumn names in the SELECT list will not match the Report Builder columns andthe report will not run


Data links:

Data links relate the results of multiple queries. A data link (or parent-childrelationship) causes the child query to be executed once for each instance of itsparent group. When you create a data link in the Data Model view o f 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 viewthe SELECT statements for the individual parent and child queries in the Builder,but can not view the SELECT statement that includes the clause created b y thedata link you define.

Note:Oracle Reports does not support data links between queries that contain columnobjects. If you attempt to create such a link, a message dialog box displays,which enables you to choose whether to tell Repor ts to create a group-to-groupquery instead (using the parent groups), o r to can cel the operation. If you want tocreate a link between any type of column and a column object, you can manuallytype the SQL statement using the appropriate column alias(es).


Layout Model

Layout Objects in reports:

Fra mes: Frames are used to surround other objects and protect them from beingoverwritten or pushed by other objects. For example, a frame might b e used tosurround all objects owned by a group, to surround column headings, or tosurround summaries.When you default the layout for a report, Report Builder creates frames aro undreport objects as n eeded; you can also create a frame manually in the LayoutModel view.

Note:

Frame n ame always starts with ‘ M_’.

Repeating frames: Repeating frames surround all of the fields that ar e 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 r epeating framesaround fields as needed; you can also create a rep eating frame manually in theLayout Model view.

For your understanding, consider there are more than 50 records in a table. Nowwhen you have only the frame you can display only one record.


For eg:

Without repeating frame :

Sno. Name Empid Dept1 Dinesh 56971 GE

With repeating frame :

Sno. Name Empid Dept1 Dinesh 56971 GE. . 50 Vishnu 56973 GE

Note:

Repeating Frame name always starts with ‘ R_ ’.

Define repeating frame inside main frame.


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 asummary (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 an y 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 theReport Wizard (it is named B_Column name). Also, one boilerplate object is sometimes created for each reportsummary. A boilerplate object is owned by the object surrounding it, unlessotherwise noted.


Anchors:Anchors are used to determine the vertical and ho rizontal positioning of a childobject relative to its parent. The end of the anchor with a symbol on it is attachedto the parent object.

Since the size of some layout objects may chan ge when the report runs (and datais actually fetched), you need anchors to define where you want objects to appearrelative 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 afterthe data has been fetched rather than on th eir size in the editor. It should also benoted that the position of the object in the Layout editor effects the final po sitionin 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 mar gin cannot be anchored to anythin g (i.e., theymay not be the parent or child object for an anchor).

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

• Nothing can be an chored 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 ancho red together in such a way that they h ave 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 pastebuffer. If you select the anchor and one of the objects, only the object is placed inthe clipboard.


• 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 preventsyou 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


Parameter Form

The Report Editor's Parameter Form view enables you to create a Runtime ParameterForm for your report. You can select pre-d efined system parameters for your form usingthe Parameter Form Builder, or you can create yo ur 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 Fo rm view is comprised of physicalpages(contains Boiler Plate, fields, graphics).

You specify the size of each parameter form page and the number of pages usingthe Report property sheet (double-click the report's node in the Object Navigator).

Summary Column (Report Level)

Reset At

The Reset At property is the group at which the summary column value resets to zero (ifFunction 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-lev el summaries. The summary is resetbetween p ages

Report Is used for summaries that apply to the entire rep ort, such asgr and totals. The summary is reset after the r eport (i.e., it isnever reset).

<names> 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, o r if that is not feasible, force each new record toprint 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 an y 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-levelsummaries.


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 p arent ( e.g.,master-detail-d etail), 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 creatin g summary column.

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


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

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


Step 7: Now go to “ Layout Model ”. There create a field F_3 go to its property paletteand assign source as CS_1 as below.

Step 8: Run the report.


Summary Column (Group Level)

Consider the manually created tabular report abov e. Follow the steps 1 to step 3 as aboveexample.

Step 4: Before Creating a summary column inside a Group, Select that grou p and thencreate summary column.. In data model click this icon for creating summary column.

Step 5: Right click the cs2 and go to property palette.


Now select the “ function ” as Count and “ Source ” as “PRODUCT_NO”.

Step 6: Now go to Layout model create a field “ F_4 ” inside Main frame an d go to itsproperty palette and set its source as “ CS_


Step 7: Now run the report.


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

You can display the Conditional Formatting dialog box from the Live Previewer view o rLayout 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 FormatException dialog box, the entire definition is exported to a PL/SQL format trigger. If aformat trigger already exists for the layout object, the definition in the Format Exceptiondialog box overwrites the existing trigger code wh en you confirm the Report Builderprompt.

You can edit the format trigger manually via the PL/SQL Editor; however, if yousubsequently modify the definition using the Format Exception dialog box , ReportBuilder displays a prompt to overwrite the ex isting format trigger.

Consider the above report for demo.

Step 1 to step 6 is same as above.


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

\


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)

Query:

select product_no , qty_on_hand , cost_price from product_master

Now create report manually using normal steps.

Step 3: In data model

Now click this icon for creating a fo rmula column. Then click the repo rt.


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 functio n.

Code: return :CS_1 * 0.125 ;

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

Note :

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


Step 5: Noe create a layout in layout model.



Formula Column (Group Level)

Query:

select product_no , qty_on_hand , cost_price from product_master

Step 1: Create the report in usual manner.

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

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


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

Then in the PLSQL editor write the following cod e.

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

Step 4: In the same way create a summar y column at report lev el.


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

Code:return :CS_1 * 0.125 ;

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


Placeholder Column (Report Level)

Query:

Select product_no , qty_on_hand , cost_price from product_master


Step 2: Now create a group level formula column, report level summary ( CS_1 ),placeholder ( CP_1 ), and formula column ( CF_2 ).

CF_1:

CP_1:


CF_2:

Step 3: Now create layout for this report in layout model as below.


Parameter Form (Bind Reference)

Query:select * from SALES_ORDER_DETAILSwhere product_no = :PRODUCT_NUM


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


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.


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

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 wh en the select statement includes a column,called a break column containing at least one value which repeats over multiple records.

Query:select * from sales_order

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.


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


Break Report (With Joins)

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_dispFROM sales_order,sales_order_details,product_master WHERE sales_order_details.s_order_no = sales_order.s_order_no ANDsales_order_details.product_no = product_master.product_no ANDsales_order_details.qty_ordered > sales_order_details.qty_disp

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


Now create a layout as shown below.

Then run the report.


Master-Detail Report

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

For each master record fetched, relative d etail records are fetched. Therefor e its ver ysimilar to break repo rt.

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 repo rt 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 d etail layout in which master record s 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.

SELECT s_order_no,description,unit_measure,product_rate,qty_orderedFROM sales_order_details,product_master WHERE sales_order_details.PRODUCT_NO =product_master.PRODUCT_NO


Step 1: Create a report in usual manner. Write query into data model and name it asQ_master and Q_d etail. Then create a link between the query. Select the primary key

column in “ G_master ” then click the following icon and drag the lik connect it todetail query then link is created. Set all summary column reset as to “ G_MASTER ” inproperty palette.

Step 2: Now go to Tools report wizard.


Step 3: Then Run the report.


Matrix Report

A matrix report is a summary report that presents the desire data with headingsacross the topand do wn 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 do wn 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.


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 sometimesreferred as “ Ma trix 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 do wn & across dimension group.

c. One cell or filler group:The cell group contains actual information that is represented in the cellsof cross product. For each interception of dimension group th e cell valuescontain zero, one or multiple values.

Summary Column :While creating the summary column you need to indicate the followin g:

a. The frequency o f summary i.e. the dimension gro up 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 cr eate a matrix

object press the following .


Matrix Report (Using 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

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


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

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


Now rename the group as follows:

G_description asG-quan tityG_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.


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 : Count Source : quantity Reset At : G_mthfull (Since we are restricting the count o f quantity every month)



Product order : G_descriptionFunction : Sum Source : CountquantityReset At : G_description (Since we need to sum singly item qty for all month)



Product order : G_mthfullFunction : Sum Source : CountquantityReset At : G_mthfull (Since we need to sum all item qty for all month)


Step 6: Now create a layout using report wizard.

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

For differentiating I have changed the n ames of Groups as follows:

Countquantity as filler cellSumcountquantityperdescription as qty_on_hand_all_monthsSumcountquantitypermthfull as qty_per_months
