To give a database development team sufficient flexibility to work in the most effective way, it pays to decide on what gets stored in source control as the ‘source of truth’, or ‘canonical source’ for a deployment. ![]() For example, I use a single data dictionary table for documenting the purpose of tables and columns rather than embedding extended properties in a script, and I would execute it separately, but would expect to see them in the script with the object they refer to. Like most database developers I’ll choose the quickest and most effective way of doing any task. We can use entity-relationship design tools that generate code for building or migrating databases, or we can use table-building GUIs. Our DDL code merely places the correct values in these system tables, and there are many legitimate and productive ways of doing this, in other words of designing and evolving the tables of a database. A user database is a dynamic structure created from system tables, not from code. Sure, we have modules such as functions, stored procedures, constraints, rules, views and triggers that all contain procedural code, but that’s not true of tables. In any procedural application, it is generally obvious what the source code is. What database scripts should go into source control?īefore tackling the topic of automating various database development tasks, such as generating build and object-level scripts, I ought to explain why a development team might need to generate several different types of database scripts in source control. This will then allow you to use a Flyway project together with other the Redgate Deploy tools such as SQL Data Compare, SQL Source Control and SQL Change Automation. In a subsequent article, I show how you can use this object-level script folder to have Flyway check for ‘ database drift‘, before running Flyway migrate. For each database version delivered by Flyway, it will use SQL Compare to generate both a build script, and a script folder containing the DDL scripts for each database object. I’ll show how you can use two of the tools in Redgate Deploy, Flyway and SQL Compare, along with PowerShell automation, to generate these database scripts automatically, as part of a Flyway deployment. You will often also want to produce other ‘ build artifacts‘ such as scripts or data. You may need to run checks, update reports or send a message. When you use Flyway for building or upgrading a database to a particular version, you will run “Flyway migrate”, it will execute the set of migration scripts, in the correct order, and the result is a database at the version you need.
