Столбец Postgres не существует
Кто-то еще написал запрос SQL Server, который сработал, и у меня есть задача перенести его на Postgres.
Я на самом деле не знаю ни одной базы данных, кроме самых простых команд SQL (я прорабатываю учебник и буду продолжать в любом случае, но я бы хотел решить эту проблему раньше, чем позже).
Во всяком случае, я получаю ошибку, что в строке 4,
ОШИБКА: столбец timeloggedtoday.date_logged не существует
Я думаю, что это происходит из раздела вокруг строки 89 (помеченного **), но я не могу понять, каким должен быть синтаксис - я пытался скопировать разделы WITH/AS из документов, но либо все еще совершаете ошибку или ошибка где-то еще. Вероятно, ниже приведено много повторяющихся / посторонних кодов, но я подумал, что лучше включить их все, так как я легко мог внести другие ошибки при переходе на синтаксис Postgres.
РЕДАКТИРОВАТЬ:
Если я удалю оскорбительные разделы, ошибка изменится на
ОШИБКА: столбец timelogged1daysago.date_logged не существует
который является следующей партией подобного кода, что наводит меня на мысль, что я делаю некоторую синтаксическую ошибку при именовании моей временной таблицы (правильная терминология?), но я не вижу, что не так, и трудно найти соответствующий раздел в документации Гуглить "с" или "как", что неудивительно, бесполезно.

РЕДАКТИРОВАТЬ: более простой запрос
Я думаю, что я отредактировал некоторые посторонние вещи в надежде найти эту ошибку. В любом случае, этот более короткий запрос выдает мне ту же ошибку, по крайней мере, так что, возможно, немного легче помочь мне в отладке:

Решение
Отредактировано: цитируемая заглавная буква соответствует запросу. В выводе второго сбоя ниже видно, что Postgres не нравится верхний регистр. У него есть привычка нижнего регистра всего, если вы не заставляете " цитаты.

Я бы подумал об избавлении от заглавных букв и кавычек. Это просто вызовет головные боли. В качестве примечания вы можете написать левое соединение только один раз:
-- instead of enumerating each possible interval
WHERE to_char(Now() - INTERVAL '8 days', '%Y-%m-%d') < to_char(startdate, '%Y-%m-%d')
-- select the interval
now()::date - start_date as diff
-- then build up your columns like:
case(case when diff=0 then date_logged else null end) as date_logged_today
case(case when diff=1 then date_logged else null end) as date_logged_yesterday
-- and so on ...
Также вы могли бы сделать
CASE
WHEN Ifnull(timeloggedToday.time_in_hours, 0) = 0 THEN 'No Time Logged'
WHEN timeloggedToday.time_in_hours < 3.0 THEN 'User has not logged sufficient time'
ELSE 'user has logged sufficient time'
END "STATUS_TODAY",
в функцию, чтобы избавиться от утомительной избыточности.
