Sql Postgres，在json_agg中使用json_build_对象字段的distinct
我正在进行一个查询，从一个名为branchkpis的表中检索一些数据。 branchkpis与名为branch的表有关系，而branch与组有关系，而组又与GroupKPI有关系 我正在尝试从每个分支机构的最新日期聚合这两个kpi，并且还希望插入每个分支机构的组最新kpiSql Postgres，在json_agg中使用json_build_对象字段的distinct,sql,postgresql,jsonb,Sql,Postgresql,Jsonb,我正在进行一个查询，从一个名为branchkpis的表中检索一些数据。 branchkpis与名为branch的表有关系，而branch与组有关系，而组又与GroupKPI有关系 我正在尝试从每个分支机构的最新日期聚合这两个kpi，并且还希望插入每个分支机构的组最新kpi SELECT * FROM (SELECT "api_branch"."id", "api_branch"."name"
