通过去重，会生成列的select语句：

(select b.risk from rhwl_easy_genes_new_risk b where  b.active=True and b.genes_id=a.id and b.disease='不宁腿综合征') as "不宁腿综合征",
(select b.risk from rhwl_easy_genes_new_risk b where  b.active=True and b.genes_id=a.id and b.disease='萘普生') as "萘普生",
(select b.risk from rhwl_easy_genes_new_risk b where  b.active=True and b.genes_id=a.id and b.disease='耐力') as "耐力",
(select b.risk from rhwl_easy_genes_new_risk b where  b.active=True and b.genes_id=a.id and b.disease='抗雀斑能力') as "抗雀斑能力",
(select b.risk from rhwl_easy_genes_new_risk b where  b.active=True and b.genes_id=a.id and b.disease='利培酮') as "利培酮",
(select b.risk from rhwl_easy_genes_new_risk b where  b.active=True and b.genes_id=a.id and b.disease='帕金森病') as "帕金森病",
(select b.risk from rhwl_easy_genes_new_risk b where  b.active=True and b.genes_id=a.id and b.disease='顺铂') as "顺铂",
(select b.risk from rhwl_easy_genes_new_risk b where  b.active=True and b.genes_id=a.id and b.disease='霍奇金淋巴瘤') as "霍奇金淋巴瘤",
(select b.risk from rhwl_easy_genes_new_risk b where  b.active=True and b.genes_id=a.id and b.disease='哮喘') as "哮喘",
(select b.risk from rhwl_easy_genes_new_risk b where  b.active=True and b.genes_id=a.id and b.disease='酒精性肝硬化') as "酒精性肝硬化"

把上面的语句插入， 生成最终查询：

SELECT 
p.name as "套餐",
a.name as "样本编号",
(select b.risk from rhwl_easy_genes_new_risk b where  b.active=True and b.genes_id=a.id and b.disease='不宁腿综合征') as "不宁腿综合征",
(select b.risk from rhwl_easy_genes_new_risk b where  b.active=True and b.genes_id=a.id and b.disease='萘普生') as "萘普生",
(select b.risk from rhwl_easy_genes_new_risk b where  b.active=True and b.genes_id=a.id and b.disease='耐力') as "耐力",
(select b.risk from rhwl_easy_genes_new_risk b where  b.active=True and b.genes_id=a.id and b.disease='抗雀斑能力') as "抗雀斑能力",
