These tools all offer Git as the version control technology plus at least one other (Subversion, Mercurial, and so on). It is sometime useful to store database script files in version control in a format that matches or resembles a layout that will be familiar from use of GUI tool, such as SSMS or TOAD. We need to distinguish between low-level version control tools, usually a combination of client tool and server engine, such as Git or Subversion, and version control platforms that provide deep integration with other tools and a rich, browser-based user experience, such as Github or Bitbucket Server (previously known as Stash). In addition, several other DLM practices depend on version control. There is no versioning on each client; the users can work offline, but there is no history saved for any of these changes and no other user can access those changes until the user connects to the central server, and commits them to the repository. This will open the "Connect Database to Version Control" dialog. A good source control system should make it simple for people across the organization to track changes to files. This section will discuss some of the version control practices that will help. I've tried the VS2010 also, but in my opinion VS approach is too complex for small and mid-size projects. By contrast, trunk-based development encourages good discipline and practices such as committing small, well-defined units of work to a single common trunk branch. This is especially important in mixed Windows/Mac/*NIX environments, where newline characters can sometimes cause problems with detecting differences. Any build and version-control system must allow developers, as well as people outside the development team, to be able to see what is changing and why, without having to rely on time-wasting meetings and formal processes. It means that there will be a number of perfectly valid approaches to managing the change process. Ease collaboration across distributed teams. In this tutorial, we will explain how to set up your project within DB Version Control when there are multiple environments available (e.g. reproducing a reported bug). Oracle SQL Developer is a free graphical tool that enhances productivity and simplifies database development tasks. The local repository contains all the history, up to the last synchronization point, thus searching for changes or listing an artifact’s history takes little time. Download source code - 4.35 KB; Introduction. I keep doing work at sites where none of the database code is stored in version control (source control) systems. Perform a code review, checking coding standards and conventions, first-class command-line access for experts, helpful GUI tools for less experienced users, browser-based code review: diffs, commenting, tracking, tickets, an HTTP API for custom integrations and chat-bots, integration with issue trackers and other tools, Copyright 1999 - 2020 Red Gate Software Ltd. Without good version control practices, large parts of DLM will remain difficult for your organization to achieve, so getting it right is vital. Other options such as Beanstalk ( may work if you have a homogeneous code environment, because they are more focused on the Linux/Mac platforms. A simple example is a change that renames the person.fname column to person.first_name. Type in the repository path under which the database scripts should be saved. The database developers implement the interface, also stored in the VCS. Collaboration Platform DoltHub hosts Dolt databases, providing tools such as hosting, permissions, query interface, and more, all designed to facilitate seamless data collaboration. The need for branching in version control often arises from the choices, explicit or otherwise, made by people in the commercial, business, or program divisions of an organization. A version control system provides an overview of what development... 3. SQL Source Control from Redgate is the first step to getting your database into version control and giving it the same treatment as your application code. A VCS allows the team to copy a particular set of files, such as those in the trunk, and use and amend them for a different purpose, without affecting the original files. The VCS is a mechanism to ensure that the database source that has been stored is identical to what was released. Subversion can also act as a low-cost artifact repository for storing binary files. When working in a branch, there is a strong risk of isolating changes for too long, and then causing disruption when the merge ambush eventually arrives. Databases, and their interactions with other databases, applications or services, are not immune from the general rules that apply to other interconnected systems. If you use an older version of TFS, you should either switch to an alternative VCS or upgrade to TFS 2015 or later in order to take advantage of Git support. With a DVCS like git, you can make multiple local commits (say two commits for whitespace and layout reformatting, followed by some semantic changes) before pushing to the central repository. In order to maintain a high level of service of a database, we need to integrate and test all changes regularly (see the Database Continuous Integration article). This approach is particularly useful for DLM because it opens up a dialogue between software developers and IT Operations people, including DBAs; both groups need to collaborate on the location of the configuration files and the way in which the files are updated, and both groups have a strong interest in the environment configuration being correct: developers so that their code works first time, and operations because they will have fewer problems to diagnose. Be sure to follow the links to K. Scott Allen's series of articles. Putting database code into a version control system makes it much easier... 2. A VCS platform that makes it easy for DBAs or Ops teams to review proposed database changes, while automatically storing all the traceability information, will encourage tight feedback loops between Ops and Dev and other stakeholders. Normally, the complete build scripts would be generated automatically from the nightly integration build, after it has passed its integration tests (see the Database Continuous Integration article). Matthew Skelton explains how to make sure your version control system fully supports all phases of the database lifecycle, from governance, development, delivery and through to operations. With SQL Examiner I mostly work with SSMS and use SQL Examiner to check-in updates to SVN (TFS and SourceSafe is supported also, but I never tried it). Git’s superior workflow model together with lightweight branching, merging, and history operations make Git the best choice for most teams. In a DVCS, users feel safer knowing their changes are versioned locally, but won’t affect others until they push them to the central repository. Examples of self-hosted VCS platforms include Gitolite, Gitlab, Bitbucket Server and Team Foundation Server. Encourage the commercial teams to do regular joint-exercises of prioritizing all the features they want to see implemented, thus reducing the number of downstream simultaneous activities. If a VCS saves database scripts at the ‘object’ level then each file corresponds to a table or routine. In our series of blog posts about Version Control and the Database, we’ve explored the history of version control, why databases have some unique requirements, and why it’s important to include them in your VCS.. An increasing number of organizations are choosing to use cloud-hosted or SaaS providers for their VCS, due to the reduction in operational overhead and the increased richness of integration offered by SaaS tools. Applies to: SQL Server (all supported versions) Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics Parallel Data Warehouse. A popular approach within development is to create feature branches in addition to release branches. Version control pays dividends when it is integrated with issue tracking. In the previous tutorial, we showed how to get started with DB Version Control tool to start versioning your SQL Server database. If this sort of tool is used to update source control, then the only changes will be the ones that the user wants. In my experience, teams work more effectively when they focus on completing a small number of changes, rather than tackling many things in parallel; develop one feature at a time, make it releasable. This small console application exports information about a database from SQL Server to an XML file. Using Oracle SQL Developer, you can browse database objects, run SQL statements, edit and debug PL/SQL statements and run reports, whether provided or created. This will make it easier to break down the development work per logical area of the database, and minimize interference when all developers are committing to trunk. Other developers can then continue to work undisturbed on “mainline”. Every application or database that we build should originate from a version in the source control system. An alternative is a migration-based approach, which uses a series of individual change scripts to migrate a database progressively from one version to the next. The modern VCS is highly reliable and data loss is extremely rare, making it ideal to depend on for automation. Source Control for Oracle. It will therefore see any changes of text as a change. Figure 2 shows the colored console output for a comparing current to previous versions, after a commit that contained both whitespace reformatting, and a behaviour change, making the latter (an increase in the width of the LastName column from 50 characters to 90) much harder to spot. Press the space key then arrow keys to make a selection. This means that we must not include in the scripts any configuration properties, such as data and log file locations, nor any permission assignments, because at that point, we need one set of database scripts per version per environment. Tools such as a database comparison tool will parse the text of the SQL to create a parse tree and compare these rather than the text. This tip is aimed to show how to use source control with Microsoft Team Foundation Server 2012 in SQL Server Management Studio (SSMS) to check-out and check-in code for co-development amongst SQL Developers. There is also an argument that SaaS VCS tools are more secure than self-hosted tools, since most self-hosted VCS tools security management is average at best. This deal-driven approach to software development typically requires the use of branching in version control, leading rapidly to unmaintainable code, failed deployments, and a drastic reduction in development speed. By a similar strategy, we can avoid creating custom branches per customer requirements. In this model, per-environment security is tricky to set up, but merging and tracking changes is easier than in the first approach. Without this ability, SQL code will continue to lag behind the application code. DevOps, Continuous Delivery & Database Lifecycle Management Go to the Simple Talk library to find more articles, or visit for more information on the benefits of extending DevOps practices to SQL Server databases. Specifically, the commercial team often tries to undertake many different activities simultaneously, sometimes with a kind of competition between different product or project managers. Another organizational choice that tends to increase the use of branching is support for multiple simultaneous customized versions of a core software product, where each client or customer receives a special set of features, or a special version of the software. It also allows the team to share out the issue-fixing effort more equally and monitor progress. After clicking OK you will be prompted for user credentials … Any audit is made much easier if the auditor can trace changes that are deployed in production all the way back to the original change in the VCS. Each repository should, ideally, have just one main branch plus the occasional short-lived release branch. The following sections outline this strategy in more detail. With either system, if the team allow changes to live for too long in individual machines, it runs counter to the idea of continuous integration and will cause problems. Any commit of a set of changes should be working and releasable. However, teams often end up losing much of the time they gained from parallel development streams in time-consuming merge operations, when the different work streams need to be brought together. Version control and deployments often only focus on application code, with database changes following a separate process. In database development, it is relatively straightforward to adopt a similar strategy. It will also include text in comments, even whitespace, which in SQL has no meaning, in contrast to an indentation-based language such as Python. Either of these approaches will most likely lead to increased trust in environment configuration and more rapid diagnosis of environment-related problems. You need to store in version control everything that is Mercurial is similar to Git, they both use similar abstractions. By placing under source control everything we need to describe any version of a database, we make it much easier to achieve consistent database builds and releases, to find out who made which changes and why, and to access all database support materials. For databases that support multiple applications, if the delivery of all the changes that span the applications and database haven’t been planned properly, then the subsequent ‘big bang’ integration between application and database changes can be painful and time-consuming. Consider a commit to be like the end of a paragraph of text: the paragraph does not simply trail off, but makes sense as a set of phrases, even if the text is not finished yet. It means that we can test and “dark launch” database changes, such as adding a new table or column, ahead of time, and then adapt the application to benefit from the change at a later point. In a centralized system, any user with access to the central server, can see the full repository history, including the last changes made by teammates or other people with access to the repository. Database developers and application developers must carefully track and negotiate any changes to the interface. Database developers write database instructions and in some cases can be used a source control tool, but in most cases is useless. This allows the developer to reference the source of defects, quickly and uniquely, and thereby save a lot of debugging time. SQL Server Database Source Control using Visual Studio Online: Git October 23, 2015 by Sifiso W. Ndlovu. With source-controlled archives, it is always obvious where the source of any material is, who made which alteration and update, when and why; Any materials, whether code, instructions, training materials, support information, configuration items, step-by-step disaster recover procedures, signoffs, release documents, entity-relationship diagrams or whatever, can be accessed easily. Background. Migration-based tools - help/assist creation of migration scripts for moving database from one version to next. Learn how to automate your application and database CI/CD pipeline by using Visual Studio Team Services. While this approach works for many source code version control systems, there is an inherent problem applying it to databases: the way you get from the start to the final state is as important as getting there. There is no code control for DBA because is a logic question. By applying the rules that govern the interfaces between any systems, it is possible to make database changes without disrupting applications, as well as avoid complex branching strategies, and ensuring that our database code is free from dependencies on database configuration and server-level settings. This can come in handy when you have a version control system like SVN or GIT that manages all of your source code but lacks any way to track the changes you make to your tables in SQL Server. Because the SQL Server security model is hierarchical, CONTROL at a particular scope implicitly include… I have read and been told many times that it is a “best practice” to version control my database. SQL Server Data Tools (SSDT) and the Data Tier Application Framework (DACFx) are add-ons for Visual Studio and SQL Server that allow us to better manage our SQL databases from development through to deployment. Unless you have a good reason to do otherwise, you should use Git as the version control repository part of your VCS. A typical example is the creation of a “release” branch to freeze code for a release while allowing development to continue in the development branch. Modern text editors make it simple to import whitespace settings such as the number of spaces to indent when the TAB key is pressed, or how code blocks are formatted. The following describes the general conventions that are followed for naming permissions: 1. This restriction is there because an older version cannot know about file format changes that were introduced in the newer release. If the subdirectory you specify does not exist, VersionSQL will create it for you the first time you commit. In many cases, we will store the files related to the main development effort in a common root subfolder of the VCS, often named trunk, but sometimes referred to by other names, such as main or mainline. If a branch lasts only a few days, the person who created the branch knows exactly why it exists and knows what needs to be merged into the main branch; the drift from the main branch is small. Also, when release-gates need sign-off, the participants can see what changes are in the release and what is affected by the change. This may sound like strange advice, given how much focus is placed on branching and merging in VCS, but by minimizing the number of branches, we can avoid many of the associated merge problems. Usability should be high on the wish-list for any VCS, particularly if it must be easily-accessible to other teams besides developers, such as testers and database administrators, as well as governance and operations people. Right-click on your database in the Object Explorer pane and select "Connect to Version Control". Branches that are short-lived can be a valuable asset to teams working with DLM. But how is DB Version Control different? Source control integration is the first step in building your continuous integration and deployment pipeline with the dedicated SQL pool resource in Azure Synapse Analytics. I believe that either flavor of VCS, centralized or distributed, can work well as long as it fits with the preferred workflow of the team, and provided that the right culture and accountability exists in the team. You can edit the generated script or check it into source control and subsequently execute the script in your existing SQL database deployment processes and DevOps pipelines with standard multiplatform SQL command line tools such as sqlcmd. CONTROLConfers ownership-like capabilities on the grantee. Therefore, beyond the tables, routines and static/reference data, we also need consider the broader database environment, and place into version control elements such as: Unless we have in the VCS the correct versions of all the scripts necessary to create our database objects, load lookup data, add security accounts, and take any other necessary actions, we have no hope of achieving reliable and repeatable database build, release and deployment processes, nor of coordinating database upgrades with changes to the associated application.
