Summary of "Explicit Cursors in Database Management"

Explicit cursors are used to control the execution when dealing with multiple records in a database.
When declaring a cursor, it is associated with a select statement to retrieve records.
The select statement associated with the cursor is not executed when the cursor is declared, but an active set is generated in the memory.
The active set contains the results of the select statement execution and is used for fetch operations.
After declaring and associating a select statement with the cursor, the cursor can be manipulated to retrieve records from the associated select statement.
The fetch operation is used to retrieve records from the active set associated with the cursor.
The explicit cursor allows for precise control over record retrieval and manipulation in database management.
It is necessary to define explicit cursors to manage the execution of multiple records effectively.
The active set generated in the memory contains the results that need to be retrieved through fetch operations.
The cursor is opened to access the active set and retrieve records from the associated select statement.
The steps involved in working with explicit cursors include declaration, association with a select statement, manipulation, and fetch operations.
The explicit cursor provides a mechanism for efficient and controlled handling of multiple records in database management.
