There are certain circumstances where SQL Server will silently truncate data, without providing an error or warning, before it is inserted into a table. In this tip we cover some examples of when this occurs.

As a production Database Administrator, I do not want to give Developers direct access to the SQL Server Agent job log especially for servers in the DMZ. Another problem we have is that when there is a lot of log data for a job, the default job log doesn't contain the full log detail and that makes it harder to troubleshoot. Most of all, we are trying not to use a different code set for deployment based on the environment. Basically we want to use the same methods to deploy our jobs to Development, Test and Production.

The most critical task for all DBAs is to have a Backup and Recovery strategy that ensures, every day, that in the event of a disaster they can restore and recover any database, within acceptable limits for data loss and downtime. Even with all the required backups in place, it's easy to miss subtle failings in the overall plan that can, and eventually will, defeat your recovery plans.

In February 2008, Microsoft announced a record-breaking data load using Microsoft® SQL Server® Integration Services (SSIS): 1 TB of data in less than 30 minutes. That data load, using SQL Server Integration Services, was 30% faster than the previous best time using a commercial ETL tool. This paper outlines what it took: the software, hardware, and configuration used. We will describe what we did to achieve that result, and offer suggestions for how to relate these techniques to typical scenarios. Even for customers who don't have needs quite like this benchmark, such efforts can teach a lot about getting optimal performance.

There are several different ways of restricting access to SSIS packages and confidential information they contain. However, preventing unauthorized users from running or viewing the content of your code is not the only security measure that you should take into consideration.

Sometimes, you have to test out alternative indexing strategies, but the task of creating the candidate indexes would just take too long. Is there another way? Well, yes, why not use the same method the DTA (Database Tuning Advisor) uses, and take the tedium out of the job.

Despite NTEXT and TEXT being deprecated in SQL Server for some time they are still both used in production systems. In this article, I will briefly demonstrate the difference between a VARCHAR (MAX), NVARCHAR (MAX) and the NTEXT data types, and the impact on performance from using NTEXT/TEXT.

I upgraded a SQL Server 2019 instance to SQL Server 2025. I wanted to test the fuzzy string search functions. I run this code:
SELECT JARO_WINKLER_DISTANCE('tim', 'tom')
I get this error message:Msg 195, Level 15, State 10, Line 1 'JARO_WINKLER_DISTANCE' is not a recognized built-in function name.What is wrong? See possible answers
