1. An indexed view is referring only one base table. Both view and table are having index defined on them. Which index would be utilized when a query executed against the table.

2. I have an indexed view, now base table data has been modified, does the modified data reflected in view automatically?

3. Does “TRUNCATE” DDL or DML command?

4. I have written a recursive CTE, it’s been running infinitely and failed with an error. The requirement is that the recursion required for 45000 times. How could you be able to handle the situation?
