Question
There are many cursor types in which we should choose any one to perform cursor implementation in SQL. Below are the various cursor types. Choose the set of cursor.
Solution
In SQL, there are four types of cursors that you can choose from to perform cursor implementation. These are:
-
Static Cursor: This type of cursor takes a snapshot of the data at a particular moment in time and uses it for all operations. It does not reflect any changes made to the database after the cursor is opened.
-
Dynamic Cursor: This cursor reflects all changes made to the database after the cursor is opened. It is the opposite of a static cursor.
-
Keyset-Driven Cursor: This cursor is a hybrid of static and dynamic cursors. It behaves like a static cursor in that it takes a snapshot of the data when the cursor is opened, but it also allows for updates and deletions like a dynamic cursor.
-
Forward-Only Cursor: This cursor only fetches
