Prisma

```
type Test implements Node {
  content: String!
}
```
↓
```
type Test implements Node {
  content: String!
  createdAt: DateTime!
  id: ID! @isUnique
  updatedAt: DateTime!
}
```
↓
```
_allTestsMeta(filter: TestFilterorderBy: TestOrderByskip: Intafter: Stringbefore: Stringfirst: Intlast: Int): _QueryMeta!
allTests(filter: TestFilterorderBy: TestOrderByskip: Intafter: Stringbefore: Stringfirst: Intlast: Int): [Test!]!
Test(id: ID): Test
```

For example, “Test” creates “allTest”.  In particular, there are many Mutations. Is there any material that understands this regularity? Can I only know these on Playground?

You can open the DOCS tab in the Playground to see those, or you can export the schema from the Playground. That contains all generated queries and mutations too.
