+ }) + .prepare('get_user_by_email') + +// Execute with parameters +const user = await getUserByEmail.execute({ email: 'user@example.com' }) +``` + +## Best Practices + +### Performance +- Use indexes for frequently queried columns +- Use `select()` to limit returned columns +- Use prepared statements for repeated queries +- Implement pagination with `limit` and `offset` +- Use connection pooling in production +- Batch inserts with `values([...array])` + +### Type Safety +- Always infer types from schema: `typeof table.$inferSelect` +- Use Zod schemas for runtime validation +- Export types

+ +```typescript +export class UserRepository { + async findById(id: number): Promise { + return db.query.users.findFirst({ + where: eq(users.id, id), + }) + } + + async findByEmail(email: string):
