STATIC CURSOR Meaning and
Definition
-
A static cursor is a term used in database management systems to refer to a result set generated by a query that remains fixed or static during the course of a transaction or session. In other words, a static cursor does not reflect any changes made to the underlying data after the cursor is opened.
When a static cursor is created, it essentially takes a snapshot of the data at the time of cursor creation. The result set provided by the static cursor does not change even if the data it was derived from is modified or updated by other concurrent transactions. This means that the result set remains constant regardless of any changes occurring in the database.
Static cursors offer certain advantages in specific situations. For instance, they provide a consistent view of data, ensuring that an application does not retrieve unexpected or inconsistent results due to concurrent updates. Static cursors are particularly useful in scenarios where data integrity and transaction consistency are critical.
However, it is important to note that using static cursors comes with certain limitations. Since the result set does not reflect the most up-to-date data, it may not be suitable for real-time or dynamic applications that require immediate access to the latest information. Additionally, static cursors may consume more memory resources compared to other types of cursors, as they hold a complete copy of the result set.

Etymology of STATIC CURSOR
The word "static" is derived from the Greek word "statikos", meaning "causing to stand". It later evolved in Late Latin to "staticus", which referred to things pertaining to standing or rest. In English, "static" is used to describe something that is not moving or changing.
On the other hand, the word "cursor" is derived from the Latin word "cursor", which means "runner" or "courier". In computer science, a cursor is an indicator on a display screen that shows the position where the next character will be inserted.
When combined, the term "static cursor" refers to a cursor or pointer that remains fixed or unchanged in its position, typically used in database management systems. It is called "static" because it does not move dynamically and remains in a fixed location until manually adjusted.
