Preserve upper-case when mapping SQL identifiers to Go identifiers

[em-ily-dev]

What do you want to change?

It would be great if sqlc could leave upper-case letters as upper-case when mapping SQL identifiers to Go identifiers.

The existing behavior works pretty well for all-lowercase SQL identifiers using underscores:

(SQL)          (Go)
request_id  => RequestID
http_id     => HttpID
artwork_key => ArtworkKey

But some databases use camel-case naming convention. Currently, sqlc changes upper-case letters to lower-case, producing:

(SQL)         (Go)
RequestID  => Requestid
HTTPID     => Httpid
ArtworkKey => Artworkkey

My proposal: leave upper-case letters as upper-case, and otherwise keep the existing behavior. This wouldn't affect anyone who uses all-lowercase SQL names, and it would produce nicer results for mixed-case SQL names:

(SQL)         (Go)
RequestID  => RequestID
HTTPID     => HTTPID
ArtworkKey => ArtworkKey

If this is acceptable, I'd be happy to submit a patch.

How does it sound?

I think the desired behaviour should be to only uppercase the first character and let the reset of the characters preserve their original case.
If that's the case, I have fixed it by replacing strings.Title with code that only uppercases the first character.
