Samsung's SmartSSD comes with a Xilinx FPGA accelerator that can be used to execute code without having to move data outside the device. And their open source SDK includes domain-specific routines including databases.

See https://xilinx.github.io/Vitis_Libraries/ for details on their software stack.

It's not SQL, but Samsung made a Key Value SSD that uses short keys instead of "addresses" to index blocks of data.

It's been done.

Imagine an SSD serving up query responses! I love it.
