Andy Grove / @andygrove:
We would want to upgrade to a more recent version of sqlparser-rs but there have been breaking API changes to that project so this might be a fair bit of work.

Davis Silverman:
Are you working on this now? I have made a bit of progress on this. Made the types, and have been fixing up errors. You say it may be a bit of work so maybe its harder than it seems, but I think I have been doing pretty well so far.

 

Here is my branch so far: sinistersnare@ba465f8

 

If you think that there is a better issue for me, let me know, I would be happy to help. I just kind of look at the '1.0.0 release' supertask and picked this one.
