Since I posted about jobs that run too long (Stop Jobs That Run Too Long – SQLRx), I thought I would also post about a way to have a daily failed jobs report sent to whomever needs it. One issue that seems to be prevalent on many servers is that jobs get set up and […]

One of the simplest yet most impactful performance optimizations for SQL Server is relocating the tempdb system database to a fast, dedicated disk—especially if that disk is temporary or ephemeral. This is a common practice in cloud environments and high-performance database systems where tempdb churn is high and doesn’t require persistence across reboots. In this […]

This article explains how the EXCEPT and INTERSECT T-SQL operators can help compare query results when tuning SQL Server queries, stored procedures, and views. Recently, a customer requested that I optimize several SSRS financial reports that frequently took between one and three minutes to complete. These reports were driven by complex code involving user-defined functions, […]

Problem Have you ever had transactional replication mysteriously start showing significant latency at a subscriber server? If so, check to see if the primary keys from the publisher database are missing on the subscriber database! Replication was showing long latency while the publisher and subscriber servers were not heavily utilized. Microsoft generated stored procedures that […]
