sql子查询可从6个表连接中获取夏季报告

Question

我想通过加入6个表格来生成夏季报告

1. 类别包含投资领域（矿产，农业，建筑等）的列表

2. 投资内容包含许可编号，投资者ID，类别ID

3. 投资者包含性别，investor_id，姓名..

4. investment_details联系人investment_id，proposed_investment_amount，real_invested_amount，proposed_male_employment，proposed_female_employment，real_male_employment real_female_employment

5. investment_status持有investment_detail_id和project_status_id

6. project_status保留project_status_id和说明（pre-implementation, implementation, operation, canceled）

我的报告预计会生成mineral, agricultural, construction和male的类别（针对female），投资额（取决于if project status is operation sum of real_invested_amount else proposed_investment_amount）就业（取决于{{ 1}}）和项目状态计数（每个project status is operation sum of real_male_employment+real_female_employment else proposed_male_employment+proposed_female_employment）。

任何有效的提示或代码将不胜感激

我的sql表和插入数据如下

pre-implementation, implementation, operation, canceled
