What is the difference between Drop, Delete and Truncate statements in SQL Server?
Drop, Delete and Truncate - All operations can be rolled back. All the statements (Delete, Truncate and Drop) are logged operations, but the amount of information that is logged varies. Delete statement logs an entry in the transaction log for each deleted row, where as Truncate Table logs only the Page deallocations.Hence, truncate is a little faster than Delete. You can have a where clause in Delete statement where as Truncate statement cannot have a where clause. Truncate will delete all the rows in a Table, but the structure of the table remains. Drop would delete all the rows including the structure of the Table. Please refer to the screen shot below for the differences summary snapshot between Drop, Delete and Truncate statements in SQL Server.
