![]() Review and check the objects that should be synchronized. These results can be exported in the below show export output types: Now, when everything is set, in the bottom-right corner click the Compare button and the compare of SQL Server database schema will start by running the standalone applicationĪs can be seen, the standalone application is shown now with the comparison results: Note that instead of the right-click command, a destination database information can be entered directly in the Schema compare query window and the Destination data type can be changed, so it doesn’t necessary limits comparison to a SQL Server database, rather than choosing one of the five data source types mentioned above:īefore starting the comparison process, switch to the Options tab in the Schema compare query window where various comparison and synchronization options can be set: Now, right-click a destination database that needs to be synchronized and click the Set as destination command: The Schema comparison query window is now shown and a source database is loaded: To initiate the SQL Server database schemas comparison with ApexSQL Diff, follow these steps:Ĭonnect to a SQL Server database via the Server Explorer or SQL Server Object Explorer panel, or if a connection already exists, right-click it, locate the Schema compare in the list and click the Set as source command: Once the application is installed, along with the host integration part, it can be accessed from Visual Studio main menu by going to Extensions > ApexSQL > ApexSQL Diff: ![]() In this example, Visual Studio 20 are checked for the integration, but the process will be shown in Visual Studio 2019. To perform SQL Server database schema comparison from Visual Studio with ApexSQL Diff, during the installation of the application under the integration step, check the Visual Studio version that will be used:īy default, Visual Studio and SSMS versions that are installed on a machine are shown in this step, but when all versions are installed, make sure to check only the desired one(s). While it can compare the previously mentioned data sources, it can create a synchronization SQL script direct synchronization on a destination data source, C# solution, and executable installer. This tool can compare SQL Server database schemas, backups, script folders, snapshots, and source control projects. The other tool that will be described in this article is ApexSQL Diff – a standalone tool, with an option to integrate into SQL Server Management Studio (SSMS) and Visual Studio. Support to synchronize other data source typesĪutomation of the comparison and synchronization process Warnings before the synchronization process starts However, it’s noticeable lack of a couple of things:īackup a target database before synchronization, or a rollback script in cases when something goes wrong To learn more, check out this article on how to compare SQL Server database schemas in Visual Studio.Īs explained, the Schema Compare feature of Visual Studio has an easy way to compare SQL Server database schemas, and it has almost everything when it comes to scenarios like this one. ![]() This is where all information can be viewed to check if a target SQL database was successfully updated or if it failed and why: Once desired objects are selected to be updated in the target database, click the Update button and the process will start:Īfter the update process is finished, the execution messages are shown in the Messages panel. This will provide results and for each selected object in the Results grid, the source, and target SQL object script can be seen in the Object Definitions panel below: Once selected, the Compare button should be clicked, and the comparison process will be initiated. In the newly opened query window, the SqlSchemaCompare query window, source, and target SQL databases should be chosen from the drop-down list: This feature can be located under the Tools > SQL Server > New Schema Comparison: So, they need a tool that can handle comparison of SQL Server database schemas, push (synchronize) schema changes to the QA database without errors and enable developers to review actions and any potential issues before the synchronization process.įirst, let’s start with the built-in feature that Visual Studio has for comparing SQL Server database schemas – the Schema Comparison feature. Once the development part is done, developers will need a tool to compare SQL Server database schemas and push schema changes to the QA database for further testing before reaching production. ![]() When working in a development environment, developers often use Visual Studio for coding, and it also has an option to connect to SQL Server and open a query window in which they can work on creating new objects or updating existing objects directly on their local Dev database, which further requires a way to compare SQL Server database schemas with the QA database.
