In the world of databases, efficiently retrieving and managing data is crucial. SQL, the standard language for managing relational databases, offers various tools and techniques to handle this task. Among these, joins are essential for combining data from multiple tables based on specific conditions. A commonly used join type is the Left Outer Join, especially…(Continue Reading)

When working with Oracle PL/SQL, developers frequently encounter the data types VARCHAR and VARCHAR2. At first glance, these might appear interchangeable, but they have distinct differences, both in their usage and historical context. Understanding these differences is critical for database developers and architects aiming to design robust and future-proof applications. What Are VARCHAR and VARCHAR2?…(Continue Reading)

The UTL_ENCODE.BASE64_DECODE function is part of Oracle’s UTL_ENCODE package, which provides utilities for encoding and decoding binary data. Specifically, the BASE64_DECODE function decodes a Base64-encoded string back into its original binary format. This is commonly used when handling encoded data in applications, such as data transfer, storage, or processing. Syntax UTL_ENCODE.BASE64_DECODE(encoded_data IN RAW) RETURN RAW;…(Continue Reading)

The UTL_ENCODE.BASE64_ENCODE function is part of the Oracle UTL_ENCODE package, used to encode binary data into a Base64 string. Base64 encoding is a widely used method for encoding binary data into an ASCII string format, ensuring safe transmission or storage in environments that handle text. The UTL_ENCODE.BASE64_ENCODE function is typically used when binary data (e.g.,…(Continue Reading)

Oracle PL/SQL provides developers with a robust set of tools for managing and manipulating data efficiently. Among these tools is the UTL_ENCODE package, a specialized utility that offers encoding and decoding functionality. This package is essential for scenarios where data transformation is necessary for secure transmission, storage, or compatibility with other systems. In this blog,…(Continue Reading)
