SQL:2023

• Comment: I'm a bit torn here. There is precedent for this from articles for other SQL standards, and this is probably notable, but I'd really like to see more than one source to really establish that. (Admittedly the other articles aren't great in that regard either, but that's WP:OTHERSTUFFEXISTS.) LittlePuppers (talk) 18:22, 2 June 2023 (UTC)
