TIL (okay, a couple days ago) that there is a json_agg() function in PostgreSQL.

SELECT
  r.review_id,
  r.review_timestamp,
  json_agg(a.*) AS answers
FROM $schema.review r
INNER JOIN $schema.answer a ON a.review_id = r.review_id
WHERE -- stuff
GROUP BY review_id, review_timestamp

Now I get just one row returned for each relevant review, and each row contains a JSON string with all the answers associated with that review. 🙂

    $schema.answer

    Not sure why my brain is expecting a ? or :schema.answer there

    We use Postgres's "schemas" to separate each client's data -- functionally similar to having them each in their own database, except they're not. 🙂 That query was actually extracted from the PHP code that builds the query (and simplified and anonymized here), so $schema would actually be replaced with the relevant schema name for the client being processed, e.g FROM client_foo.review r, and then processed with $pdo->prepare().

      This saddened me a bit. Watched "You Only Live Twice" and "Thunderball" this weekend in his honor. Wish I had a copy of "Robin and Marian", the chemistry he had with Audrey Hepburn was amazing. And I might be a fan indeed as I don't even hate Zardoz TOO much.

      Finally, pretty good compilation of the early Bond themes: https://youtu.be/J4jdUhxOz0M

        Zardoz is fun if not taken seriously. 🙂

        "The Man Who Would Be King" is pretty darned good. He and Michael Caine make a great pair in it.

          TIL that the film 'Lawrence of Arabia' had its world premiere 10 years closer to the start of the Great War than to the current day.

            sneakyimp you might not like what else ol' Zardoz has to say...

            You sound like my wife 😆

            Remember, at the end Connery comes to find out that part ain't true after all ... 😄

              TIL that returning false works if you declare return type int:

              function foo() : int {
        return false;
}
var_dump(foo());

              the result:

              int(0)

              but returning NULL from an int function throws an exception:

              function foo() : int {
        return null;
}
var_dump(foo());

              the result:

              PHP Fatal error:  Uncaught TypeError: Return value of foo() must be of the type integer, null returned in /tmp/a.php:3
Stack trace:
#0 /tmp/a.php(5): foo()
#1 {main}
  thrown in /tmp/a.php on line 3

              You'll also get that if you try to return a non-numeric string (a numeric string would be recast).

              Also, attempting to return anything other than an int fail if you declare(strict_types=1);.

              Returning null is hazardous, and equivalent to returning nothing at all (return null; is identical in meaning to return;; if a function is supposed to return a value, return; looks wrong). If for some reason you do want nulls hanging around, you can declare the possibility as function foo(): ?int.
