Solution

The name of the cursor written and maintained by a database user is called a "User-Defined Cursor".

Here are the steps to create a User-Defined Cursor:

  1. Declare the cursor: This is done using the DECLARE statement. You need to specify the SQL query that will be used to retrieve the data.

  2. Open the cursor: This is done using the OPEN statement. This will execute the SQL query and store the result in the cursor.

  3. Fetch the data: This is done using the FETCH statement. This will retrieve the data one row at a time from the cursor. You can continue to fetch data until all rows have been retrieved.

  4. Close the cursor: This is done using the CLOSE statement. This will release the memory used by the cursor.

  5. Deallocate the cursor: This is done using the DEALLOCATE statement. This will remove the cursor definition and release all resources associated with the cursor.
