Node.js 删除查询时的内部连接，节点JS，Knex JS

此查询可用于：

  var query = knex('project_member')
    .join('project', 'project_member.pm_project', '=', 'project.prj_id')
    .join('users', 'project_member.pm_user', '=', 'users.us_id')
    .where({
      prj_number: inputs.params.prj_number
    })
    .select('pm_project', 'us_name', 'us_alias');

query.toString提供：

select "pm_project", "us_name", "us_alias" from "project_member" inner join "project" on "project_member"."pm_project" = "project"."prj_id" inner join "users" on "project_member"."pm_user" = "users"."us_id" where "prj_number" = '4026305'

delete from "project_member" where "prj_number" = '4026305' and "pm_user" = '1'

此查询不起作用：

  var query = knex('project_member')
    .join('project', 'project_member.pm_project', '=', 'project.prj_id')
    .where({
      prj_number: inputs.params.prj_number,
      pm_user: inputs.params.pm_user
    })
    .del();

query.toString提供：

select "pm_project", "us_name", "us_alias" from "project_member" inner join "project" on "project_member"."pm_project" = "project"."prj_id" inner join "users" on "project_member"."pm_user" = "users"."us_id" where "prj_number" = '4026305'

delete from "project_member" where "prj_number" = '4026305' and "pm_user" = '1'

无法在删除查询上使用联接？是否必须进行单独的查询才能加入它们？

似乎删除连接无法正常工作，可能是因为不同数据库的删除连接语法非常不同，但您应该能够将查询重写为简单的IN查询

从项目成员中删除 其中pm_用户= 以及 从prj_编号= …应由未经测试的程序生成

knex“项目成员” .其中'pm_user'，inputs.params.pm_user .其中“pm_项目”的功能{ 这个。选择“prj_id” .来自“项目” .其中“prj_编号”，输入.params.prj_编号； } 德尔先生

…在数据库中运行来自Internet上随机用户的具有潜在破坏性的SQL之前，请始终记住备份数据-

您能看到生成的SQL吗？从未使用过knex，但可能是通过设置？使用sql输出更新了问题。工作！很不错的。塔卡！
