I know about DDL triggers at schema level and DML ones at table level. Is the other way round also possible. I am using DDL trigger at schema level to prevent DDL's for any object. Now I want to apply DML on all schemas if applied in one schema. Can I have a trigger in a cursor where the cursor is helping us to loop through all the tables. I also want delete revoked from all except 3 tables. Will there be any conflict from 1st requirement with 2nd.
