IntroductionEncryption refers to the process of blurring data by using a key or a password. In SQL Server, encryption does not replace other security settings, such as preventing unauthorized people from accessing the database or the Windows system where the database instance resides, or even the computer room where the database resides, but as the last line of d

When a user database is available and TDE is enabled, encryption is implemented at the page level when it is written to disk. Decrypts when the data page is read into memory. If a database file or database backup is stolen, the original certificate that is not used for encryption will not be accessible. This is almost the most exciting feature of the

secure than its previous version, it is possible for an attacker to obtain stored data. As a result, data encryption becomes a more thorough data protection strategy, and even if an attacker is able to access data, it has to be decrypted, thus adding a layer of protection to the data. The previous version of SQL Server 2000 did not have built-in data

we use a undocument query prompt directly to the statement, forcing the parallel cost threshold for the query to be dropped to 0, forcing the statement to go in parallel, and the statement execution time from 20 seconds to 5 seconds (note: Use a hash join hint for 7 seconds). The following is a simple example showing the effect of using this hint, example T-SQL as shown in Listing 1: SELECT * from [adventureworks].[ Sales]. [SalesOrderDetail] A I
