From 6efee751dbeb795b1759bba2bc4385f35539b582 Mon Sep 17 00:00:00 2001 From: Filippo Menghi Date: Fri, 5 Jun 2026 10:20:42 +0200 Subject: [PATCH] docs: add 'more questions to try' to the public-DB section MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Lowers the activation barrier — a new user can paste a working query in under a minute without inventing one. All three examples were run against EMBL-EBI's public RNAcentral DB and verified to return real rows (top source databases, Rfam family count, longest Rfam consensus sequences). Different query shapes so the range is visible. --- README.md | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/README.md b/README.md index e93df65..7d59d92 100644 --- a/README.md +++ b/README.md @@ -86,6 +86,14 @@ prq --query "for each Rfam clan, show the clan name and how many Rfam models bel That's the exact query in the demo above — a real `JOIN` + `GROUP BY` across a 216-table schema you've never seen.
