Hello
Yes, there is a difference between SQL Server Standard 2019 and SQL Server Standard Runtime 2019.
SQL Server Standard 2019 is a full-featured edition of SQL Server that includes all the features and capabilities of the SQL Server Database Engine. It delivers basic data management and business intelligence database for departments and small organizations to run their applications and supports common development tools for on-premises and cloud.
On the other hand, SQL Server Standard Runtime 2019 is a special edition of SQL Server designed for embedding SQL Server technology into third-party applications. The “Runtime” label indicates that it’s intended to be used as part of another application, rather than as a standalone product.
Not all SQL Server Standard software come labeled as Runtime. The Runtime version is specifically designed for certain use cases and is not the standard version of the software. The standard version of SQL Server is typically used for a wider range of applications and use cases.
