Oof. Just imagine trying to telling someone about it. "It's pronounced this way but you spell it this way" rarely ends up well, and often ends up un-searchable.

Or just XQL? It could be branded as eXcel Query Language.

Or SQXL

SXQL rolls of the tongue easier, but might not be acceptable to management for . . . other reasons.
