The database administrators of today face an increasingly complex set of IT requirements that must be met to ensure the integrity, security and performance of their databases. One of the most important – and often overlooked – requirements is the enablement of Change Data Capture (CDC) in SQL Server. CDC is a feature of SQL Server that tracks and logs data changes that occur in a database, so that the data can be monitored, managed and audited. Without this feature enabled, organizations run the risk of not being able to audit and monitor the data changes in their databases, rendering them vulnerable to malicious attack or data loss. In this blog post, we will explore the benefits of enabling CDC in SQL Server and discuss the best practices for doing so. We will also discuss the risks associated with not enabling CDC, and provide an overview of the steps required to enable it.

How to check CDC enabled in SQL Server
Checking if CDC (Change Data Capture) is enabled in SQL Server can help ensure that your database is secure and up to date. CDC is a feature that enables tracking of data changes in a database. It works by capturing database changes and storing them in an external database. This allows for easy tracking of changes, as well as the ability to roll back changes if necessary.
To check if CDC is enabled in your SQL Server database, you will need to run a query. Start by connecting to your database using Microsoft SQL Server Management Studio. Once you’re connected, you can run the following query to check if CDC is enabled:
How to query CDC tables in SQL Server
Querying tables in SQL Server can be a daunting task for even experienced database administrators. To assist in this process, the Microsoft SQL Server provides access to the CDC (Change Data Capture) tables, which can help identify and track changes to data stored in the database. Knowing how to query these tables is an important part of the database administrator’s skillset.
To query the CDC tables in SQL Server, you must first identify the table to be queried. The CDC table names begin with “CDC” and are followed by the name of the table from which the change data is captured. Once you have identified the table, you can query it using the SELECT statement to retrieve the data stored in the table. It is
How to enable CDC for all tables in SQL Server
Enabling Change Data Capture (CDC) for all tables in Microsoft SQL Server is a straightforward process. The first step is to enable CDC at the server level, which can be done in the SQL Server Management Studio (SSMS) by right-clicking the server name and selecting “Properties.” Under the “CDC” tab, check the box labeled “Enable Change Data Capture” and click “OK.”
Next, create a database for the CDC. The CDC database will contain all the change data information and must be configured separately from the user database. To create the CDC database, right-click the server name in SSMS and select “New Database.” Enter a name for the database and click “OK” to create it
Does SQL Server support CDC?
In general, SQL Server, Azure SQL Managed Instance, and Azure SQL Database all support change data capture. Nov 18, 2022.
How do you check if CDC is enabled or not?
You can check a database’s status by running a query against the is_cdc_enabled column in the sys databases catalog view. The cdc schema, cdc user, metadata tables, and other system objects are created for the database when change data capture is enabled. Nov 18, 2022.
How enable CDC for specific table in SQL Server?
In Microsoft SQL Server, there are two ways to enable Change Data Capture. CDC can be enabled on specific tables or at the database level. A member of the sysadmin fixed server role must execute a stored procedure (sysadmin.sp) to enable Change Data Capture at the database level. sp_cdc_enable_db) in the database context. Nov 21, 2022.
