Oracle® Reports Building Reports
10g Release 2 (10.1.2)
In this chapter, you will learn about tabular reports, the most basic report style. By following the steps in this chapter, you can generate the report output shown in Figure 5-1.
Figure 5-1 Tabular report output
A tabular report is the most basic type of report you can build. The report output is organized in a multicolumn, multirow format, with each column corresponding to a column in the database table. In this example, the column labels Department Id, Department Name, Manager Id, and Location Id are derived from the columns in your SQL
SELECT statement, but you can modify column labels as you wish.
Generally, the first step is to define the data Oracle Reports should fetch from the database by creating a query that contains a
SELECT statement. Although this example report uses only one query, reports can contain any number of queries.
For each query you create, Oracle Reports automatically creates one default group. The default query names are
Q_2, and so on. The default group name is
fieldname is the first field of the table specified in the query. For example, if the first field of the table
FIRSTNAME, then the default group name is
For each database column you specify in the query's
SELECT statement, Oracle Reports creates a report column and assigns it to the group. By default, the columns appear in the order in which you enter them in your
SELECT statement. The default column names are generated from the database column names or replaced by any aliases specified in your
If you select two or more columns with the same name, the first column is given the default name, the second column is given the default name with a 1 appended to it (for example,
Deptno1, and so on).
Before you can run your report, you must specify the layout (that is, the format) of the report output. If you do not, Oracle Reports will fetch the data but will not display it; you may receive an error message, depending on whether you choose paper or Web layout.
For this example report, you will use the tabular layout style, which is one of eight styles provided by Oracle Reports. The tabular layout displays data in a series of columns running down the page, with the column headings displayed directly above the columns.
As you build this example report, you will:
Use the Report Wizard to create a report with a paper layout that includes one query to select all of the columns displayed in this report. Oracle Reports will create all other necessary objects (for example, groups and columns) by default.
To see a sample tabular report, open the examples folder named
tabular, then open the Oracle Reports example named
tabular.rdf. For details on how to open it, see "Accessing the Example Reports" in the Preface.
To build the example in this chapter, you must have access to the Human Resources sample schema (HR) provided with the Oracle Database. If you do not know if you have access to this sample schema, contact your database administrator.
When you create a report, you can either use the Report Wizard to assist you or create the report yourself. To build the simple report in this example, you can use the Report Wizard. Using the wizard enables you to define the layout for the report, as well as set the data definition.
To create a simple report:
Launch Reports Builder (or, if already open, choose File > New > Report).
In the Welcome or New Report dialog box, select Use the Report Wizard, then click OK.
If the Welcome page displays, click Next.
On the Report Type page, select Create Paper Layout Only, then click Next.
On the Style page, type a Title for your report, select Tabular, then click Next.
On the Data Source page, click SQL Query, then click Next.
On the Data page, enter the following
SELECT statement in the Data Source definition field:
SELECT ALL DEPARTMENTS.DEPARTMENT_ID, DEPARTMENTS.DEPARTMENT_NAME, DEPARTMENTS.MANAGER_ID, DEPARTMENTS.LOCATION_ID FROM DEPARTMENTS ORDER BY DEPARTMENTS.DEPARTMENT_ID
Tip:This query selects all the department IDs, the department names, the manager IDs, and the location IDs, then sorts the data by the department IDs.
Note:You can enter this query in any of the following ways:
Note:If you are not already connected to a database, you will be prompted to connect to the database when you click Query Builder or Next. Ensure that you connect to a database that has the appropriate schema for this example. Section 5.1, "Prerequisites for this example" describes the sample schema requirements for this example.
On the Fields page, click the double right arrows (>>) to move all of the fields to the Displayed Fields list, then click Next.
On the Totals page, click Next.
On the Labels page, click Next.
On the Template page, select Predefined Template and click Beige, then click Finish to display your report output in the Paper Design view. It should look something like this:
Figure 5-2 Paper Design view for the tabular report
Note:In the Paper Design view, you can see how the tabular report displays the data like a table, in order of department ID number.
Save the report as
Congratulations! You have successfully created a tabular paper report. You now know how to:
define a tabular report layout using the Report Wizard.
