A Guide to Oracle9i34 Manually Creating a Query and Data Link

A Guide to Oracle9i35 Creating Reports that Display Calculated Values Formula columns –Display values that PL/SQL functions calculate using report data field values as input parameters Summary columns –Perform summary functions (such as SUM,AVG, or MAX) on report data fields

A Guide to Oracle9i36 Example of Calculated Values

A Guide to Oracle9i37 Creating Formula Columns Formula columns: –Display a value that a user-defined function returns as a result of performing computations on report data values To create: –Create the formula column in the report Data Model –Write the user-defined function that returns the calculated value for the formula column –Create a layout field in the report to display the formula column value
