In Oracle Forms, developers often need to apply dynamic changes to individual records in a multi-record block rather than affecting all records at once. The built-in SET_ITEM_INSTANCE_PROPERTY makes this possible. With this built-in, you can alter the appearance, functionality, and…
Oracle Application Express (APEX) is a low-code development platform that enables rapid application building on top of Oracle Database. For experienced professionals, interviews typically go beyond the basics and focus on architecture, performance tuning, security, integration with external systems, and…
Oracle Reports is a powerful tool for developing reports based on Oracle databases, widely used in enterprises for creating professional, interactive, and printable reports. If you are preparing for an interview, you can expect questions that cover everything from basic…
Preparing for an Oracle Forms interview can feel challenging because the questions often cover a wide range of topics—from the basics of Oracle Forms architecture to advanced built-ins and integration with PL In this article, you will find 50 carefully…
In many Oracle Forms applications, there is a need to write data or export information directly to the client’s local machine. Traditionally, Oracle Forms operates on the application server, meaning file operations happen on the server by default. However, with…
Printing is one of the most common requirements in enterprise applications built with Oracle Forms. Traditionally, Oracle developers have relied on Oracle Reports Builder to generate and send reports to printers. However, there are situations where using Reports Builder is…
Oracle Forms provides developers with a powerful way to build interactive and dynamic applications. Often, you need to change how items (such as text fields, checkboxes, or buttons) behave depending on user actions, data values, or business rules. This is…
In Oracle Forms applications, multiple users often access and modify the same data at the same time. To avoid data conflicts and ensure consistency, Oracle Forms provides mechanisms to lock and unlock records. This functionality prevents two users from editing…
When working with Oracle Forms, there are times when you need to remove all records from a data block. This is common when refreshing data, resetting forms for new input, or discarding records fetched from the database. Oracle Forms provides…
Working with files directly from the database can be an essential part of enterprise applications. Whether you need to generate reports, export data, or import information into Oracle tables, the UTL_FILE package in PL/SQL provides a reliable way to handle…
Modern Oracle Forms applications often need to integrate with the web—whether to display reports, open online resources, or navigate to external systems. Oracle Forms provides the WEB.SHOW_DOCUMENT built-in for this purpose. It enables developers to open a specified URL in…
In Oracle Forms, most logic is executed within the database or the application itself. However, sometimes developers need to interact with the operating system—for example, to run scripts, open external programs, or perform administrative tasks outside the form. Oracle Forms…
When working with Oracle Forms, developers often use Record Groups to manage lists of values (LOVs), populate dropdowns, or store query results temporarily. A Record Group is essentially an in-memory data structure that holds rows and columns, similar to a…
Oracle Forms applications often require developers to communicate with users during runtime. Whether it’s to confirm an action, provide feedback, or show an error, clear messages improve usability and reduce confusion. One of the simplest yet powerful ways to achieve…
When you need fresh records from the database in Oracle Forms, EXECUTE_QUERY is the workhorse. It fetches rows into the current data block based on search criteria, default WHERE clauses, and block properties. Used well, it keeps your screens responsive…
When you change properties, update display-only fields in a loop, or start a time-consuming task, the Oracle Forms UI may not repaint immediately. Users then see “frozen” values or stale visuals, even though your code has already updated them. The…
In multi-form Oracle Forms applications, developers often need to manage navigation between different forms that are already open. Instead of repeatedly reopening forms, Oracle provides built-ins like FIND_FORM and GO_FORM. These built-ins allow you to check whether a form is…
In Oracle Forms, applications often consist of multiple forms that need to interact with each other. Navigating between these forms is a common requirement, and Oracle provides several built-in procedures to achieve this. Two of the most important ones are…
