![]() ![]() ![]() Perform an AG failover and verify the column-level data encryption It shows the encrypted data from the secondary ![]() Now, run the select statement on the readable secondary replica. “Yes” so that the user can connect to the secondary and run the select statements. Right-click on the availability group and check the value for the Readable Secondary column. We can read data from the synchronized secondary replica in a SQL Server Always On Availability Group. Read data from the secondary replica in a SQL Server Always On Availability Group In the primary replica, we have encrypted data, as shown below. To configure the column-level encryption in an availability group, create the following table in the ĭatabase on the primary replica instance. In this article, I use the two-node availability group in synchronous commit mode.Ĭolumn-level SQL Server encryption with SQL Server Always On Availability Groups In this article, we will explore column level encryption for the database part of the SQL Server Always On ![]() In the article, An overview of the column level SQL Server encryption, I explored the column level encryption using the symmetric keys in a standalone You want to encrypt only the sensitiveĬolumn, i.e. Suppose you have a customer table holding the customer credit card number.
