Azure SQL Database - Transparent Data Encryption

Transparent Data Encryption offers the ability to encrypt content of the database, its transaction logs, as well as backups while at rest. Encryption and decryption are performed in real-time, at the individual page level, as the database is being written to and read from storage, without necessitating changes to applications accessing their data. Marcin Policht reviews the feature.

Question of the Day

RegEx Functions II

I have this data in a table in a SQL Server 2025 database:

EmailAddressID EmailAddress
7              dylan0@ADVENTURE-WORKS.COM
8              Diane1@ADVENTURE-WORKS.COM
If I run this query, which row(s) are returned?
SELECT top 10
 *
 FROM person.EmailAddress
 WHERE REGEXP_LIKE(EmailAddress, '^d')
 AND BusinessEntityID IN (7,8)
