How to fix P2008: Failed to parse the query `{query_parsing_error}` at `{query_position}` in Prisma

P2008: Failed to parse the query `{query_parsing_error}` at `{query_position}`

P2008: Failed to parse the query. Unknown field: "userNmae" at "users.findMany.where"

// Problem: Typo in field name
const users = await prisma.user.findMany({
  where: {
    userNmae: "John" // Should be "userName"
  }
});

// Solution: Use correct field name
const users = await prisma.user.findMany({
  where: {
    userName: "John"
  }
});

npx prisma studio

cat prisma/schema.prisma

// Problem: Passing string to numeric field
const user = await prisma.user.findUnique({
  where: {
    id: "123" // If id is Int, this is wrong
  }
});

// Solution: Use correct type
const user = await prisma.user.findUnique({
  where: {
    id: 123 // Correct numeric type
  }
});

// Problem: Passing number to string field
const posts = await prisma.post.findMany({
  where: {
    title: 123 // title is String
  }
});

// Solution: Use string
const posts = await prisma.post.findMany({
  where: {
    title: "My Post"
  }
});

// Problem: "Query" is a reserved GraphQL keyword
model Query {
  id    String @id @default(cuid())
  name  String
}

// This fails with P2008: "Error parsing GraphQL query"
const queries = await prisma.query.findMany();

// Solution: Use a different name
model SearchQuery {
  id    String @id @default(cuid())
  name  String
}

const queries = await prisma.searchQuery.findMany();

// Problem: Invalid JSON structure
const user = await prisma.user.create({
  data: {
    name: "John",
    metadata: "{invalid: json}" // Invalid JSON string
  }
});

// Solution: Use proper JSON object or string
const user = await prisma.user.create({
  data: {
    name: "John",
    metadata: { valid: "json" } // Prisma handles serialization
  }
});

// Or with valid JSON string
const user = await prisma.user.create({
  data: {
    name: "John",
    metadata: JSON.parse('{"valid": "json"}')
  }
});

// Problem: Incorrect SQL syntax
const result = await prisma.$queryRaw`
  SELECT * FROM User WHERE id = $1
`; // Missing parameter

// Solution: Include all parameters
const userId = 123;
const result = await prisma.$queryRaw`
  SELECT * FROM "User" WHERE id = ${userId}
`;

// Problem: Wrong table name (case-sensitive in PostgreSQL)
const result = await prisma.$queryRaw`
  SELECT * FROM user
`; // Should be "User" with quotes

// Solution: Use correct table name with quotes
const result = await prisma.$queryRaw`
  SELECT * FROM "User"
`;

// Problem: Invalid configuration syntax
import { defineConfig } from 'prisma/client'

export default defineConfig(
  adapter: d1Adapter, // Missing braces
  schema: './prisma/schema.prisma'
)

// Solution: Correct configuration structure
import { defineConfig } from 'prisma/client'
import { PrismaD1 } from '@prisma/adapter-d1'

export default defineConfig({
  adapter: d1Adapter,
  schema: './prisma/schema.prisma'
})
