Please add SxQL

[fukamachi]

SxQL is a dynamic SQL builder library for Common Lisp.

Neat! Are you familiar with S-SQL from postmodern? It seems like it
covers similar ground, but is more postgres-specific.

[fukamachi]

Yes, I know S-SQL. I have never used it in any applications, though.

This project does not build in SBCL because defstruct left-join-clause has a slot named ":on", which sbcl 1.1.13 has recently prohibited via full warnings. Is it meant to be named by a keyword? Maybe SBCL should be more lenient...

[fukamachi]

It isn't needed to be a keyword... Thank you for pointing it out.
I've fixed it in 3bf6574.
