In Oracle, you can create a continuous delete statement by using a loop and setting a condition for when to stop the deletion process. Here's an example of how you can do it:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16
17
18
19
DECLARE
    v_count NUMBER;
BEGIN
    LOOP
        DELETE FROM your_table
        WHERE condition; -- Specify the condition for deleting rows
        
        COMMIT; -- Commit the deletion
        
        SELECT COUNT(*) INTO v_count
        FROM your_table
        WHERE condition; -- Check how many rows are left
        
        IF v_count = 0 THEN
            EXIT; -- Exit the loop if no rows are left to delete
        END IF;
    END LOOP;
END;
/


In this example, you will need to replace your_table and condition with the actual table name and condition you want to use for deleting rows. The loop will continue to delete rows from the table that match the specified condition until there are no more rows left to delete. Remember to be cautious when using continuous delete statements to avoid unintended data loss.
