ORACLE Report 6i

TCS INTERNAL

OVERVIEW Oracle Report 6i is a D2K tool which will

help us to build simple and complex production quality report.

While making a report in our GEHC project we don’t use the Report Wizard. We make the report manually. It gives us much flexibility to develop report.

Report Editor DATA MODEL: It displays a structural representation of the data in a

report. The object do not appear in the report output, but the structure determines the layout style and the data objects provide the values that appear in the layout objects. ( Data Structures and Values to be displayed).

LAYOUT MODEL: Displays the layout objects in a report and allows us to make many modifications to any layout object. All layout objects have properties that we can modify in a property pallet.

The hierarchy of the layout is determined by the DATA model.

(Formatting information about how the values will appear in the output)

DATA Model Objects

TCS INTERNAL

DATA Model Objects

Query: Select the DATA for our report. Group: Organize the data to form the

required hierarchical structure Columns: Contain individual data

values. Database columns exist by default or contain the data from the database column or expressions defined in the query.

We can also create Formula, Summary and Place Holder Column Types.

TCS INTERNAL

Data Model Formula Column Performs a user-defined computation Executes a PL/SQL function Must return a value Can be a Character, Number, Date Returned value must match datatype

function CF_SALCALCFormula return Number isbegin

return(:salary)end;

TCS INTERNAL

Data Model:Placeholder An empty container at design time Populated by another object at run time

Before report trigger Formula column at report level Formula column in same group or below placeholder

CP_xxx

CF_xxx

NOTE: You cannot populate a placeholder by writing code in the placeholder’s own

Formula property.

TCS INTERNAL

DATA Model Objects Data Link: Join queries for complex data

relationships. 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

There are three types of DATA Links are present Query to Query Group to Group Column to Column

TCS INTERNAL

DATA Model Objects Parameter: Provide for runtime

deafults or user input We can create also the User

Parameters There are basically two types of

user parameters we create Bind Parameter Lexical Parameter.

TCS INTERNAL

Data Model: Parameters: User Parameter

Bind reference replaces a value :parameter_name parameter object is created by default

Lexical reference replaces a clause &Lparameter_name parameter object is never created by

default

TCS INTERNAL

Restrict values in a WHERE clauseSELECT NAME, SALES_REP_IDFROM S_CUSTOMERWHERE ID > :P_CUST

Substitute a single value or expression in the select statement

SELECT NAME, SALES_REP_IDFROM S_CUSTOMERORDER BY DECODE(:SORT, 1, NAME,

2, STATE, COUNTRY)

Data Model: Parameters: User Parameter

TCS INTERNAL

Data Model: Parameters: User Parameter

Use to substitute any part of the query.SELECT NAME, SALES_REP_IDFROM S_CUSTOMER&LP_WHERE_CLAUSE&LP_ORD_CLAUSE

SELECT NAME, SALES_REP_IDFROM S_CUSTOMER&LP_WHERE_ORD_CLAUSE

SELECT &LP_CUST CUST, &LP_SALESREP REPFROM &LP_TABLE

Ensure number of values and datatypes match at runtime!

TCS INTERNAL

Always do the following Specify column aliases when

substituting column names. Create lexical parameters explicitly in

the Object Navigator (Report Builder creates bind parameters if necessary).

Enter an initial value for parameters that affect query validation when NULL.

Data Model: Paramete: User Parameter

TCS INTERNAL

Layout Model Objects Frame : Contains objects and print

only once Repeating Frame: Contains other

objects and print once for each record of the associated groups.

Field: Contains data and other variable and their formats.

Text: We can use this for Lebel.

TCS INTERNAL

Layout

Layout Model: Layers

F_xxx F_xxx

R_G_xxx

M_G_xxx

Body

Repeating frame displays for each row of data that is retrievedfor a group

Group frame encloses other objects and controls the format, frequency, and position of several objects simultaneously.

Fields define the appearance of columns; can contain character, number, date, for each database column

Report Triggers:

There are 5 types of report Triggers. But we commonly use three types of Report Triggres

1> After Parameter Form.2> Before Report.3> After Report.

TCS INTERNAL

Format Trigger

BOOLEAN TYPE

TCS INTERNAL

Format Trigger

Format Triggers:Exist on most layout objectsCan suppress entire layout section

(master group frame): no records fetched

Can suppress display of individual records (repeating frame): all records fetched
