Thank you @Schwem for this PR.

However I'm working with MS team to integrate these connectors directly into Kernel memory and SK core repositories. At this time, there is an official connector for KernelMemory for MSSQL Server : https://github.com/microsoft/kernel-memory/tree/main/extensions/SQLServer/SQLServer

The implementation of MSSQL connector into KernelMemory is in progress, and I've reported you change into: https://github.com/microsoft/semantic-kernel/pull/6482

Note: There is a SL server connector in Semantic Kernel, this uses vector search feature of SQL server, which is currently in preview and available into Azure SQL server instances.
