JSON Support in PostgreSQL, MySQL, MongoDB, and SQL Server

Updated 2/10/2017

If you've been watching the evolution of database technologies over the past few years, you've seen how quickly JSON has quickly cemented its position in major database servers. Due to its use in the web front-end, JSON has overtaken XML in APIs, and it’s spread through all the layers in the stack one step at a time.

Most major databases supported XML in some fashion for a while, too, but developer uptake wasn’t universal. JSON adoption among developers is nearly universal today, however. (The king is dead, long live the king!) But how good is JSON support in the databases we know and love? We’ll do a comparison in this blog post.

I have already shown how this works when getting data out of Oracle in releasing MyOraDump, so inline with that the corresponding program to get data out of SQL Server is called MyMSSQLDump and it has features along same same lines as MyOraDump. To connect to SQL Server (or Sybase, but this I haven't tested) I use FreeTDS, which is a nice Open Source SQL Server / Sybase driver. The output formats supported are MySQL (i.e. A file with (INSERT …
