And now that Christoph has found a case where the spec allows a query of unbounded length using only keywords, let's limit it to cases with no loops

(Note, PostgreSQL accepts a number of cases of indefinite repetition, so I'm limiting this challenge to valid SQL 2016 foundation syntax)

A challenge: what SQL statement contains the longest possible sequence of consecutive keywords? (My best so far has 13 consecutive keywords)

Today's fun fact: "Tory" comes from the Irish word for a bandit. Any relevance to modern politics is left as an exercise for the reader

PSA: When asking for help, show YOUR OWN code / problem description, don't just point to a random forum post and say "I'm having the same problem as this". It makes it impossible to see what simple errors you may have made, or differences between your issue and the post

Another SQL style tip: always a space before the paren in constructs like "OVER (", "FILTER (", etc. Avoid making things look like function calls when they're not.

SQL style tip: treat "SELECT DISTINCT" as one keyword that happens to have a space in it. Never put a newline before DISTINCT, and never put an open paren directly after it. When using COUNT(DISTINCT ...), if you absolutely need a paren, then always have a space before it.

PSA: The error message is the part that starts with "ERROR:". Any DETAIL: or HINT: that follows may be informative, but it is NOT the error message. ALWAYS READ THE ERROR MESSAGE.

So now I'm curious: to the two people who voted to keep postfix operators in my poll: why? Do you have a use case or an example of existing usage?

Quick poll: should
@PostgreSQL remove support for postfix operators in expressions, or keep them? Their existence makes parsing a lot harder.Hvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -

#PostgreSQL optimization tip: when dealing with queries over many tables, consider increasing from_collapse_limit and join_collapse_limit. https://www.postgresql.org/docs/current/runtime-config-query.html#RUNTIME-CONFIG-QUERY-OTHER …Hvala.

Also it insists on labelling .h files as being C++ or Objective-C (rather than the C that they actually are) regardless of what I put in .gitattributes.

Github language statistics never cease to baffle me. Hundreds of lines of SQL and a 3-line .dir-locals.el, and it says the repo is 100% Emacs-Lisp.
