Postgresql-CTE加入CTE'；分类与分类

我的sql文件中有两个CTE：

• 第一个在存货中找到一部电影的总成本。如果库存中有一部电影的8张DVD拷贝，每张成本为10美元，那么它将输出80张作为总成本
• 第二个是电影的总收入。如果一部电影被租了20次，每次租金是5美元，那么它的收入是100美元
• 然后使用这些CTE，我需要通过计算总收入-总成本，找到最赚钱的10部电影。总成本和总收入有效，但当我加入他们时，它不起作用。有一个语法错误

请添加您得到的语法错误。错误不准确。它在最后一行“；”处显示语法错误。我知道问题不一样。这里肯定有不止一个错误。从CTE表达式中删除分号。
