Question

Shankar M · Answer

Truncate - DDL (Data Definition Language)and and Statementand Delete and  and - DML (Data Manipulation Language) Statementand Both, perform the Operation of getting rid of rows in the Specified Table. But differs in the perspective of State,When you issue Delete command for deleting Specific records in Table, Ignoringly you have deleted the wrongset of records, then the Transaction can be rolled back, which simply implies that DELETE statements or DML operation can be roll backed to previous state.Ex : When you issue a delete statement and which has a corresponding BEGIN TRANSACTION, Suppose the user disconnects then the Transaction is rollbacked.Where as when considering DDL Statements they cannot be roll backed, Simply you might think of DDL statements as Auto commit.
