title: How to disable Constraints for all the tables and enable it?
body: <p>I have 60 tables. I want to drop 10 tables where these 10 tables are Constraints(PK,FK) to other 20 tables. While dropping these 10 tables, I need to truncate or delete data from the other 20 tables. Finally I want to disable all 60 table Constraints(FK,PK) and then enable all 60 table constraints after I am done with my work of adding/dropping tables. Is this possible?</p>
  
  <p>When I drop a table it is asking for FK. When I truncate those FK dependencies it also is still showing the same. I don't want to mess with all those FK,PK.</p>
  
  <p>I want to know smarter method.</p>
