Microsoft SQL Server FAQ

Frequently asked about Microsoft SQL Server

How complex is it to self-host Microsoft SQL Server on-premises compared to cloud options?

Self-hosting Microsoft SQL Server on-premises requires significant infrastructure setup including Windows Server or Linux OS, storage configuration, and network setup. You must manage installation, patching, backups, and high availability yourself. In contrast, cloud options like Azure SQL Database abstract much of this operational overhead, offering managed services with automated backups and scaling. On-premises deployments offer more control but require dedicated DBA expertise and infrastructure resources.

Community insight informed by Reddit discussions

Does Microsoft SQL Server support offline functionality or local-only database operations?

Microsoft SQL Server is designed primarily as a server-based relational database system and does not natively support offline or local-only operations like embedded databases (e.g., SQLite). It requires a running SQL Server instance and network connectivity for client applications. However, SQL Server Express can be installed locally for development or small-scale offline use, but it still runs as a service and is not an embedded database.

Community insight informed by StackOverflow discussions

Who owns the data stored in Microsoft SQL Server, and are there any Microsoft-imposed restrictions on data access?

Data stored in Microsoft SQL Server instances is fully owned by the organization deploying the server. Microsoft does not access or control your data unless you use cloud services like Azure SQL Database where data is stored in Microsoft-managed infrastructure. On-premises deployments give you complete control over data access, security, and compliance. Licensing agreements do not impose restrictions on data ownership or access rights.

Community insight informed by Hacker News discussions

What are the limitations of Microsoft SQL Server's APIs for integrating with external applications?

Microsoft SQL Server provides rich APIs including T-SQL, ODBC, JDBC, ADO.NET, and REST endpoints via SQL Server REST API in Azure. However, some advanced features like graph queries or JSON support may have version or edition restrictions. Also, while T-SQL is powerful, it is proprietary and not fully compatible with other SQL dialects, which can limit portability. Integration with non-Microsoft platforms may require additional drivers or middleware.

Community insight informed by Forums discussions

What are the recommended migration or export paths from Microsoft SQL Server to open-source databases?

Migrating from Microsoft SQL Server to open-source databases like PostgreSQL or MySQL involves schema conversion, data export/import, and rewriting proprietary T-SQL code. Tools like SQL Server Migration Assistant (SSMA) can assist in converting schema and data. However, stored procedures, triggers, and functions often require manual rewriting due to dialect differences. Exporting data via BCP or CSV files is common, but careful planning is needed to handle data types and constraints.
