Looks kinda nice, but can it handle "IN (...)" statements correctly? Or conditionally adding some WHERE param? If not, this is rather simplistic and couldn't replace writing inline queries, and then I think I'd rather not mix together 2 approaches.
Conditional WHERE seems unapproachable with this tool - which is one of my doubts about the need of a tool like this.
If you instead approach your SQL by having each query wrapped in a function in an isolated part of your code base you, as a company/team/whatever, can choose how much logic to let reside inside of those functions - building up conditional WHERE clauses is a very common thing to need to do.
