TAILIEUCHUNG - SQL Server Tacklebox- P46

SQL Server Tacklebox- P46: This book, as with almost all books, started out as an idea. I wanted to accumulate together those scripts and tools that I have built over the years so that DBAs could sort through them and perhaps adapt them for their own circumstances. | 8 Finding data corruption With this code and an easy way to read the error logs where the dbcc checkdb results will be written which I covered in Chapter 7 you will be comforted by the knowledge that you will not let corruption seep into your data infrastructure and go unnoticed. And that you can act thoughtfully to resolve the issue once discovered. The custom query in Listing will iterate through all databases on a SQL Server instance capture errors and mail the top error to you so that you can look further into the matter.
