Wizards Wizards help you build reports and charts by asking you for all the basic information needed in an easy-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. The applications 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 from the same point.

Data model Data Definition objects

in data model:

Queries: A query contains a SQL SELECT statement that retrieves data from the database for 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 to create such a link, a message dialo g box displays, which prompts you to choose whether to create a group-to-group quer y (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 to reference the parent column.

Groups: Groups are created to organize the columns in your report. When you create a query, Report Builder automatically creates a group that contains the columns selected by the query. You create additional groups to produce br eak levels in the report, either manually or by using the Report Wizard to create a group above or group left report.

By:Malinda Ramadhani TANZANIA EDUCATION AUTHORITY Classification: Internal

Columns: Database columns: A database column represents a column that is selected b y the query. For each column that you select in your qu ery, 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.

By:Malinda Ramadhani TANZANIA EDUCATION AUTHORITY Classification: Internal

Report Level

Group Level

Placeholder columns: A placeholder is a column for which you set the datatyp e and value in PL/SQL that you define. You can set the value of a placeholder column in the following places: * 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 automatically inserts 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.

By:Malinda Ramadhani TANZANIA EDUCATION AUTHORITY Classification: Internal

Note: For group reports, the Report Wizard and Data Wizard create n summary fields 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 th e sum of 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 bind references or lexical references . Bind references: Bind references (or bind variables) are used to rep lace a single value in SQL or PL/SQL, such as a character string, number, or date. Specifically, bind references may 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 r eferenced in FROM clauses or in place of reserved words or clauses. You create a bind reference b y entering a colon (:) followed immediately by the column or parameter name. If you do not cr eate a column or parameter before making a bind referen ce 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)

By:Malinda Ramadhani TANZANIA EDUCATION AUTHORITY Classification: Internal

Lexical references: Lex ical references ar e 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 enterin g 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 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 these values 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 selected at 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, the column names in the SELECT list will not match the Report Builder columns and the report will not run

By:Malinda Ramadhani TANZANIA EDUCATION AUTHORITY Classification: Internal

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 o f your report, Report Builder constructs a clause (as specified in the link's Property Palette) that will 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 b y 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 Repor ts to create a group-to-group query instead (using the parent groups), o r to can cel the operation. If you want to create a link between any type of column and a column object, you can manually type 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 being overwritten or pushed by other objects. For example, a frame might b e used to surround 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 aro und report objects as n eeded; you can also create a frame manually in the Layout Model 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 frames around fields as needed; you can also create a rep eating frame manually in the Layout 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.

By:Malinda Ramadhani TANZANIA EDUCATION AUTHORITY Classification: Internal

For eg: Without repeating frame

:

Sno. Name Empid Dept 1 Dinesh 56971 GE With repeating frame : Sno. Name Empid Dept 1 Dinesh 56971 GE . . 50 Vishnu 56973 GE

Note: Repeating Frame name always starts with ‘

R_ ’.

Define repeating frame inside main frame.

By:Malinda Ramadhani TANZANIA EDUCATION AUTHORITY Classification: Internal

Fields: A field is the layout container for each column in the layout. A field is owned by the 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 Runtime Parameter 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 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.

By:Malinda Ramadhani TANZANIA EDUCATION AUTHORITY Classification: Internal

Anchors: Anchors are used to determine the vertical and ho rizontal positioning of a child object 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 chan ge 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 the object to which it is anchored. Positioning is based on the size of the objects after the data has been fetched rather than on th eir size in the editor. It should also be noted that the position of the object in the Layout editor effects the final po sition in the report output. Any physical offset in the layout is incorporated into the percentage 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., they may not be the parent or child object for an anchor). • A repeating frame th at is the vertical or horizontal repeating frame for a matrix cannot 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 circular dependency. • To copy an anchor, you must select the anchor and the two objects it anchors together. 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 in the clipboard.

By:Malinda Ramadhani TANZANIA EDUCATION AUTHORITY Classification: Internal

• An anchor cannot be resized. • An anchor must always be on top of the objects it anchors together (i.e., it must be one 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 on anchors. Examples: Centering fields horizontally

Centering fields vertically

Collapse Vertically and Horizontally

Parameter Form The Report Editor's Parameter Form view enables you to create a Runtime Parameter Form for your report. You can select pre-d efined system parameters for your form using the 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, or delete objects while viewing their graphical representations on the screen. The painting region of the Parameter Fo rm view is comprised of physical pages(contains Boiler Plate, fields, graphics).

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 has one). Reset At has a list of values containing valid reset groups. Reset At determines if the 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 reset between p ages Report Is used for summaries that apply to the entire rep ort, such as gr and totals. The summary is reset after the r eport (i.e., it is never reset). Is a valid group name. The summary is reset after each record of the group. Applies to summary columns.

• The reset group of a summary column may be its group or any group above its group, including Report and Page. • To ensure that page summaries behave in a predictable way, make sure each record fits on a single page, o r 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 Reset At of Page. If a summary has a Reset At of Page, then the sizing of the field or boilerplate object 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 be contained 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 frames associated with a group that is involved in the summary. One common case of this is a matrix report. As a result, matrix reports cannot have page-level summaries. By:Malinda Ramadhani TANZANIA EDUCATION AUTHORITY Classification: Internal

For multiple summary columns that are in child groups that share the same parent group, 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 give unexpected results.

Conditional Formatting Using the Conditional Formatting and Format Exception dialog boxes, you can specify output 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 o r Layout Model view in any of the following ways: Double-click the object to display the Property Palette. Under the General Layout node, 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 Exception dialog box overwrites the existing trigger code wh en 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 ex isting format trigger. Consider the above report for demo. Step 1 to step 6 is same as above.

Matrix Report A matrix report is a summary report that presents the desire data with across the topand do wn left side. The data in

middle like spreadsheet.

The totals are displayed across the A matrix report is referred as “

bottom and right side. Cross Tab ” report.

A matrix report is cross tabulation of 4 set of data: 1. 2. 3. 4.

one set across the page. one set of data do wn the page. one set of data is cross product. 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 sometimes referred as “ Ma trix Labels ”. b. One or more Cross Product group: The cross product group contains all possible combination values of the dimension group. This group is represented as intersection of repeating frames of do wn & 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 th e cell values contain 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 2. A matrix object created for cross product group. 3. Boilerplates for each column & row of values as well as for summaries.

Now rename the group as follows: G_description as G-quan tity G_1 as G_description Step 4: Now click the following icon as G_countquantity.

to create a cross product group and name that

Click the icon and select the groups G_description & G_mthfull.

Rename G_2 as G_ count_quantity.
