What is the difference between Drop and Truncate..

Answer / vipin narwal

HI TO ALL!!!

DROP: will lead in deleting the structure of the table
along with all associated constraints like Primary
Key,Foreign Key,..etc and also deallocates the memory
allocated to the Database objects..

Truncate: Truncate like Delete deletes the data associated
with a Database Object but structure remains there i.e,
memory remains allocated,...but faster than Delete...
