Traditional database integrity checks in SQL Server can be time-consuming and resource-intensive, especially for large databases, even when using super cool tools like Ola Hallengren’s maintenance solution.
To address this challenge, I developed a TSQL script for performing incremental integrity checks, which significantly optimizes the process and reduces its impact on the server.
