If you’ve accidentally dead a DROP statement and you have got a full information backup, on condition that no changes occurred when the table was born, you’ll be able to merely recover the information by overwriting the first information with the backup. However, if that’s not the case, either as a result of the information objects and information are modified when the DROP SQL statement was dead or as a result of you don’t have a legitimate information backup, there’s still the simplest way to recover all of your lost information
You’ll be needing some tools for the process which can be found at

Namely, every DROP operation is logged to the SQL Server dealings log. this implies that the dealings log stores the data needed to roll back the dealings and, on condition that the information is fully recovery mode, supports point-in-time recovery from a DROP operation
Since DROP is logged to the dealings log, it are often rolled back if it’s encapsulated inside a certain, active dealings. for example, the subsequent SQL query:
DROP TABLE Customer
SELECT *
FROM Customer
Will end in the monosodium glutamate 208, Level 16, State one error message because the client table has been born.
However, the subsequent SQL code:
BEGIN TRAN
DROP TABLE Customer
ROLLBACK
SELECT *
FROM Customer
Will come back all of the rows within the client table because the DROP operation are going to be rolled back
However, if the dealings containing the DROP operation isn’t any longer active, for example since it’s been committed, the born table can not be rolled back, and conversely the information it hold on are going to be lost in addition. will that mean that you just can’t recover the information lost because of a DROP operation if no full information backups area unit available?
