Phil Factor describes the problem of preserving data that is left 'in limbo' when you need to revert the database to a previous version that has no way of accommodating it. Read more
Cross-server references keep cropping up as a problem for development and build. Phil Factor demonstrates how using linked server 'aliases' can get around these issues, even if the individual databases use four-part references within the code rather than synonyms. Read more
Filters are used by Redgate's SQL Compare, SQL Source Control, DLM Dashboard, and SQL Change Automation. A typical use for a filter is to work on just one schema within a database or just a limited set of tables and routines. You would also want to use a filter to exclude certain object, such as database users, from comparisons. Phil Factor explains how they work, and how to create, edit and then use them within the various Redgate tools. Read more
If some of your database constraints have system-generated names, they can cause 'false positives' when comparing schemas and generating build scripts using SQL Compare or SQL Change Automation. Phil Factor explains the difficulties, and the Compare option you need to enable to avoid them. Read more
Alexander Diab demonstrates how a team of developers can work on and test features in different branches of a SQL Server database development project, while their local development database automatically remains 'synchronized' with the current branch in version control. Read more
SQL Change Automation enables users to make database changes to production safely and efficiently using PowerShell cmdlets, which can be integrated easily into any release management tool. This article will show you how to automate database deployments safely, by using SQL Change Automation from within PowerShell scripts, and how a deployment script for a release can be checked and amended as part of the process.

You want to use SQL Compare or SQL Change Automation (SCA) to create or update a database, and at the same time ensure that its data is as you expect. You want to avoid running any additional PowerShell scripting every time you do it, and you want to keep everything in source control, including the data. You just want to keep everything simple. Phil Factor demonstrates how it's done, by generating MERGE scripts from a stored procedure. Read more
Phil Factor describes how custom pre- and post-deployment scripts work, when doing state-based database deployments with SQL Compare or SQL Change Automation, and how you might use them to, for example, add a version number to the target database, specify its database settings, or stuff data into some tables. Read more
Phil Factor starts with the basics how to rebuild a set of development database from scratch, using SQL Change Automation, and then demonstrates how to check for any active sessions before rebuilding, import test data using BCP, and secure passwords if connecting to the target with SQL Server credentials. Read more
This article demonstrates how to use a 'state' approach to database source control, when the nature of the database changes cause you to hit difficulties with migrating existing data. These difficulties happen when the differences are such that it is impossible for any automated script to make the changes whilst preserving existing data. Read more
