XML and JSON Creation in SQL Server vs Elsewhere

Lukas Eder walks us through converting result sets to XML and JSON using different platforms:

SQL Server supports transforming flat tabular SQL result sets into hierarchical structures by convention using the convenient FOR XML or FOR JSON syntaxes. This is really convenient and less verbose than the standard SQL/XML or SQL/JSON APIs – although the standard ones are more powerful.

In this blog post, I’d like to show a few core features of the SQL Server syntax, and what they correspond to in standard SQL. jOOQ 3.14 will support both SQL Server’s syntax and the standard syntax, and will be able to translate from one to the other, such that you can use SQL Server syntax also on Db2, MariaDB, MySQL, Oracle, PostgreSQL. You can play around with the current state of development on our website here.
