Sql server versions compare12/27/2023 ![]() On running the comparison, SQL Compare will generate a list of database objects that exist only in the source, or exist only in the target, or exist in both but have differences. Similarly, it can work with a SQL Compare Snapshot or a SQL Source control project or a SQL Change Automaton project file. For example, it can parse a scripts folder, containing a set of DLL scripts for every database object, into a model of the database, or even a single build script. The source and target might be ‘live’ SQL Server databases, but they don’t have to be because SQL Compare can work with any representation of a database from which it can construct a ‘model’ of the structure of that database. SQL Compare will compare schemas between databases, specifically between two different versions of the same SQL Server database. SQL Compare’s comparison engine is also built into both SQL Change Automation and SQL Source Control. When used from the command line or script, SQL Compare can provide an HTML or Excel file as a report. It allows you to perform the comparisons and deployments as part of a scripted process. SQL Compare provides a command line interface (which may be subject to a different, automation-based license), both for Windows and Linux. You can use SQL Compare’s options and filters to control how it does this comparison, and what objects in ignores. a ‘1-way synchronization’ script or ‘migration’ script) that will update the target database to make its structure the same as the source, preserving the existing data wherever possible, and issuing a warning if it’s not. It will generate a deployment script ( a.k.a. It will inspect the structural differences between the source and target databases, and present side-by-side differences in the SQL DDL code of each of the tables and code modules. SQL Compare is a GUI tool to compare SQL Server databases. Generate a schema migration script for deployments.Create a point-in-time “snapshot” of a database.Create or update a database build script.Create or update a scripts folder from a database.Update a target database so it is the same as the source.After a brief recap of what it is and how it works, I’ll review how to compare SQL databases with SQL Compare, and how this makes the following common development tasks easier, less error-prone and faster: The complete listing for SQL Server 2014 Express is available from on MSDN 's Features Supported by the Editions of SQL Server 2014 (opens new window).SQL Compare is now close to 20 years old and has been put to uses that the original developers of the tool barely imagined.

Some features of SQL Server, regardless of edition, are unsupported in Linux.Īlso see the Feature Comparison FAQ for clarification on terminology. The features included below are selected base on overall popularity and value,Īnd do not represent every feature of SQL Server nor all of the parity between editions. Web Edition, SQL Server Datacenter, and other versions, they will not be included in the below comparisons. There are many otherĭifferences though, some of which can be extremely important for some applicationĭue to the rarity of SQL Server Business Intelligence, SQL Server The most well known differences between SQL Express and other editions are theĬaps on database size (10GB) and lack of a SQL Agent feature.
