如何使用TypeORM的横向联接来实现Postgres数据库？

Question

我有一个包含5个连接的postgres查询，执行该查询需要10秒钟以上的时间。我用横向联接概念重新编写了查询，现在它在不到1秒的时间内执行。我想用TypeORM编写该查询，但找不到任何方法。任何帮助表示赞赏。

这是需要转换为TypeORM的查询

FROM "institution" "i" 
INNER JOIN "financial_account" "fa" ON "fa"."institutionId"="i"."id" 
left join  (
    select h1.*
    from holding as h1
    inner join  (
        select cast(max(h3.holding_date) as DATE) holding_date,h3."accountId"
        From "holding" as h3
        group by h3."accountId"
    ) as h2 on h2."accountId" = h1."accountId" and h2."holding_date" = cast(h1."holding_date" as date)
) "h" on "h"."accountId" = "fa".id
LEFT JOIN "securities" "sec" ON "sec"."id"="h"."securityId"  
LEFT JOIN "symbol" "sym" ON "sym"."id"="sec"."symbolId" AND "sym"."trRIC"="sec"."symbolTrRIC" 
where "i".af_user_id='1234'
ORDER BY "h".institution_value desc;
