Oracle PL/SQL provides various ways to track and manage database sessions, one of which is using session identifiers. A session identifier is a unique value assigned to each session connected to an Oracle database. It helps in session monitoring, debugging, and performance tuning. This article explores how to retrieve, use, and manage session identifiers in…(Continue Reading)

PL/SQL Tablespaces
In Oracle Database, a tablespace is a logical storage unit that helps manage database storage efficiently. It acts as an abstraction layer between physical storage (data files) and logical database structures like tables and indexes. Understanding tablespaces is essential for database administrators (DBAs) and developers working with PL/SQL. What is a Tablespace? A tablespace consists…(Continue Reading)
Tablespace Partition
Oracle Database provides powerful partitioning features that allow users to manage large datasets efficiently. Partitioning helps in optimizing query performance, managing data growth, and ensuring efficient use of system resources. However, improper partition management can lead to fragmentation and performance bottlenecks. This article explores Oracle PL/SQL tablespace partitioning, fragmentation issues, and the methods for splitting…(Continue Reading)
Rebuild partition index Oracle 12c
In Oracle 12c, indexes play a crucial role in optimizing query performance. When dealing with partitioned tables, partitioned indexes help improve access speed and efficiency. However, over time, these indexes may become fragmented or need rebuilding due to maintenance tasks such as partition operations (drop, merge, split, etc.). This article covers the methods to rebuild…(Continue Reading)
Convert number to fraction
In Oracle PL/SQL, working with numbers often requires precise formatting, conversions, and manipulation. Converting a decimal number into a fraction is not a built-in function, but it can be achieved using mathematical techniques. This article will walk through the process of converting numbers to fractions using PL/SQL, explaining the logic and providing practical examples. Understanding…(Continue Reading)
