Change Tracking Inserts Require SELECT Permission

I’ve been writing about change tracking in SQL Server for some time now, but I recently came across a permissions issue on a change tracking table that I’d never encountered before. When attempting to insert data into a change tracking-enabled table using an account with no select permissions, I learned that the effective security principal must have both insert and…


SQL Server Change Tracking

Video: Introduction to SQL Server Change Tracking

SQL Server change tracking is a lightweight and synchronous mechanism for detecting inserts, updates, and deletes in tracked tables. For those of us who spend a lot of time in ETL, change tracking is a useful tool for defining what data has changed to make the extract-transform-load process more efficient. SQL Server Change Tracking In this 30-minute video, I introduce…

Webinar on Change Tracking for Data Warehouse Loads

Join me online on Tuesday, November 15th at 1:00PM as I host a webinar entitled “Managing Data Warehouse Incremental Loads with SQL Server Change Tracking”. In this webinar, I’ll discuss the essentials of incremental loads, and will introduce SQL Server change tracking. I’ll talk about how change tracking can be used in data warehouse load scenarios, and will show several…


Change Tracking for Data Warehouse Loads (Webinar)

For data warehouse professionals, data change detection is is a central part of what we do. Accurately detecting new, changed, and deleted records means the difference between doing an expensive truncate-and-reload operation versus a smaller, faster incremental load. SQL Server change tracking, a feature first introduced in SQL Server 2008, allows detection of changed data – including inserts, updates, and…


Using change tracking in SSIS

Using Change Tracking in SSIS

Recently, I wrote about how to get started with SQL Server change tracking, and I demonstrated a design pattern I use with change tracking in incremental load scenarios. In this post, I’ll round out the topic by showing how using change tracking in SSIS packages can add more flexibility to ETL processes. Using Change Tracking in SSIS In my last post I…

Using SQL Server Change Tracking for Incremental Loads

Earlier this week I wrote about the basics of change tracking in SQL Server, and showed how to get started using this technology for change detection. In this post, I’ll continue what I started by demonstrating how change tracking fits into a larger design pattern for end-to-end incremental load ETL processes. Incremental Load Overview ETL processes fall into one of…


Getting Started with Change Tracking in SQL Server

Change tracking for SQL Server is a flexible and easy-to-use technology for monitoring tables for inserts, updates, and deletes. In this post, I’ll discuss getting started with change tracking in SQL Server, and will show an example of how to get started with it. Change Tracking Overview Change tracking is a lightweight mechanism for tracking which rows have been inserted,…


Webinar: Change Tracking for Data Warehouse Loads

For data warehouse professionals, change detection is critical. Accurately detecting new, changed, and deleted records means the difference between doing an expensive truncate-and-reload operation versus a smaller, faster incremental load. This is especially important as the volume of information stored in data warehouses continues to grow. SQL Server change tracking, a feature first introduced in SQL Server 2008, allows detection…


SQL Server 2016 Service Pack 1 Changes Everything

Service Pack 1 unlocks most all of the programmability features found in Enterprise Edition, making them available in lower-cost (and even free) editions of SQL Server. Folks, this is a huge change…
