Postgresql 错误：表“”的子句条目中缺少；电影"；

我是SQL新手，需要查询数据库以提取某些信息，然后才能将其导入我熟悉的另一个软件以分析数据。此查询是由我目前无法访问的朋友发送给我的，我无法理解为什么会出现以下错误：

ERROR:  missing FROM-clause entry for table "movies"
LINE 8: FROM (SELECT movies.movieid

以下是查询：

SELECT innerselect.movieid
       ,innerselect.title
       ,innerselect.year
       ,innerselect.imdbid
       ,innerselect.budget[1] AS budget_currency
       ,TO_NUMBER(innerselect.budget[2], '999999999999990.00') AS budget_total
       ,innerselect.businesstext
FROM (SELECT movies.movieid
       ,movies.title
       ,movies.year
       ,movies.imdbid
       ,business.businesstext
       ,regexp_matches(business.businesstext, '^BT:[ ](USD)[ ](-?(?!0)(?:\d+|\d{1,3}(?:,\d{3})+))', 'g') AS budget -- creates a PostgreSQL Array which contains the content matched with the RegEx Groups FROM movies LEFT JOIN business ON movies.movieid=business.movieid WHERE movies.movieid > 2753500
) AS innerselect

任何帮助都将不胜感激

问题是，您将FROM放在与注释相同的行上，因此FROM子句被忽略

SELECT innerselect.movieid
       ,innerselect.title
       ,innerselect.year
       ,innerselect.imdbid
       ,innerselect.budget[1] AS budget_currency
       ,TO_NUMBER(innerselect.budget[2], '999999999999990.00') AS budget_total
       ,innerselect.businesstext
FROM (SELECT movies.movieid
       ,movies.title
       ,movies.year
       ,movies.imdbid
       ,business.businesstext
       ,regexp_matches(business.businesstext, '^BT:[ ](USD)[ ](-?(?!0)(?:\d+|\d{1,3}(?:,\d{3})+))', 'g') AS budget -- creates a PostgreSQL Array which contains the content matched with the RegEx Groups
      FROM movies LEFT JOIN business ON movies.movieid=business.movieid WHERE movies.movieid > 2753500
) AS innerselect
