sql server column level encryption

SQL server determines whether a database, table, column, or view exists. SQL server 1. Determine whether the database exists If exists (select * from sys. databases where name = 'database name ')Drop database [database name] 2. Check whether the table exists. If exists (sele

Encryption on SQLServer built-in encryption on SQLServer is used to protect various types of sensitive data. In many cases, this encryption is completely transparent to you. When data is stored, it is encrypted and used automatically. In other cases, you can choose whether the data is encrypted. SQLServer can encrypt the following components:

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

at this point, the understanding of nonclustered indexes is not very important.As with white pages, a SQL Server index is maintained in the search key sequence to access any particular entry in a small set of "jumps." Given a search key, SQL Server can quickly get the index entry for that key. Unlike white pages,
