所以，我一直在尝试在我现有的数据库上运行自省过程，如下所示：

npx prisma introspect

并收到以下错误跟踪：

然后我尝试在操场上运行一个查询，该查询发出以下跟踪错误：

  Stack:
Invalid `prisma.item.findMany()` invocation in

  339 }
  340
  341 args = this.paginationStrategy.resolve(args)
  342
→ 343 return photon[mappedField.photonAccessor][mappedField.operation](args
  Error occurred during query execution:

    at PrismaClientFetcher.request (C:/Users/d0475/Documents/Projects/flamingo-ecom2/sick-fits/backend/node_modules/@prisma/client/src/runtime/getPrismaClient.ts:906:15)

因此，默认情况下该过程正在尝试访问公共架构 ( message: "relation /"public.Item/" does not exist")，我没有在其中指定表/数据信息。我所有的表/数据信息都驻留在my-schema$prod. 我最初假设我需要更改数据库的 search_path 以包含 my-schema: "$user", "my-schema$prod", public，但这没有解决任何问题。

理想情况下，我需要能够将数据源中的模式指定为：

datasource db {
  provider = "postgresql"
  schema = "my-schema$prod"
  url      = env("DATABASE_URL")
}

我该如何解决这个问题？

通过向 URI 添加架构参数解决了该问题：

postgresql://myuser:mypass@somehost.com:5432/mydb?schema=my-schema$prod
