Oracle PL/SQL Cursor - Shikshaglobe

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.
