PL/SQL (Procedural Language for SQL) is Oracle's proprietary extension to standard SQL. It combines the data manipulation power of SQL with the procedural capabilities of a programming language. PL/SQL allows developers to write complex database-centric applications by incorporating variables, conditions, loops, error handling, and modular programming constructs like procedures and functions. This language is tightly integrated with Oracle databases, enabling efficient data processing and transaction management.
When working with Oracle PL/SQL, it is important to understand the correct way to define procedures within packages. In Oracle, every procedure or function that is part of a package must first be declared in the package specification before you…
A CSV file (Comma-Separated Values file) is a plain text file in which individual fields are separated by commas. This format is commonly used for exchanging data between systems because it is simple and widely supported. In this article, I…
Exporting data from an Oracle table directly into an Excel file can be accomplished easily using PL/SQL and the xlsx_builder_pkg package. This utility allows you to generate Excel .xlsx files directly from SQL queries run in your Oracle database. Below,…
PL/SQL table types—also known as collections—function similarly to arrays in other programming languages. Using PL/SQL collections, you can process large volumes of data efficiently and perform bulk operations with ease. In this article, I will introduce some of the most…
Sometimes, you may need to move a file from one directory to another within your Oracle database environment. Oracle provides a convenient way to accomplish this task using PL/SQL, but before you begin, you must ensure that directory objects exist…
Sometimes, you may encounter a situation where you have a very large text or CSV file that is cumbersome to open or process all at once. In such cases, it is often useful to split the large file into several…
When we want to know the current local time in any country, we often use Google to search for this information. However, in Oracle PL/SQL, you can retrieve the current local time for any country directly using built-in features. In…
