Oracle PL/SQL Cursor
Cursors are used to fetch data from database tables. A cursor is a pointer that enables traversal of the rows in a database table. The set of rows the cursor holds is referred to as the active set. Oracle provides various types of cursors, such as:· Anonymous blocksExplicit cursorsImplicit cursorsEach type of cursor has its own advantages and disadvantages. In general, explicit cursors are more efficient than implicit cursors because they are lessresource-intensive. However, explicit cursors require more code and are more difficult to use than implicit cursors.PL/SQL Cursor is a data type in the Oracle PL/SQL programming language that enables traversal of records in a database. A cursor can be thought of as a pointer to a specific position in a result set. By default, cursors are not visible to other users and are only accessible within the session in which they were created.PL/SQL Cursor is a looping structure that enables you to fetch and process data one row at a time from a result set. It is very useful in situations where you need to process data row by row. For example, if you want to update the salary of all employees by 10%, you can use a cursor to loop through all the rows in the emp table and update each row.A cursor is a pointer that identifies a specific row within a database table. This enables the rows to be updated or deleted, one at a time. In Oracle PL/SQL, a cursor can be either implicit or explicit. An implicit cursor is created automatically by Oracle when DML statements (such as INSERT, UPDATE, and DELETE) are executed. An explicit cursor is defined and controlled by the programmer.
The Importance of ORACLE PL/SQL CURSOR in Today's World
In the realm of database management and programming, ORACLE
PL/SQL CURSOR stands as a fundamental component. A cursor essentially acts as a
pointer to a specific row in a result set, allowing developers to fetch and
manipulate data row by row. This capability is crucial for tasks like data
analysis, report generation, and data transformation. By using cursors,
developers can navigate through large datasets efficiently and perform complex
operations with ease.
Exploring Different Types of ORACLE PL/SQL CURSOR
ORACLE PL/SQL CURSOR comes in several types, each tailored
to specific use cases. From Implicit Cursors that are automatically
generated when executing SQL statements, to Explicit Cursors that
developers define and manage themselves, the range of options caters to diverse
programming requirements. Moreover, Ref Cursors are used to return
result sets from stored procedures, while Dynamic Cursors enable
developers to construct SQL statements dynamically.
