What is Cursor in SQL? A cursor in SQL is adatabaseobject that allows you to retrieve and manipulate data one row at a time. Cursors are typically used when performing operations on each result set row, such as updating or deleting. Cursors are similar to pointers in programming, allowing...
Java’s avoidance of explicit pointers is one way it improves security. A pointer holds the location of another item in memory, which may be utilized for accessing the memory of another process. The elimination of pointers is the solution to this problem. Additionally, we may set access restri...

offers developers and database administrators a flexible programming environment. They can set up rules governing the relationships between different data fields, such as one to one, one to many, unique, required, or optional, and add “pointers” among different tables. The system enforces these...
The derived data types in C++ include arrays, pointers, references and functions. All four types are used frequently to provide additional functionality to the basic data types and to build more complex programs. In C++, one data type can be converted to another data type. This is known as ...
