Data models

Public TypeScript types Prisma exposes. This page lists the most commonly referenced ones and where they live.

PrismaClientOptions

The constructor options for new PrismaClient(...). Validated in packages/client/src/runtime/utils/validatePrismaClientOptions.ts.

Field	Type	Notes
errorFormat	'pretty' | 'colorless' | 'minimal'	Error rendering style
adapter	SqlDriverAdapterFactory	Required in Prisma 7. Without it, P2038 at instantiation
accelerateUrl	string	Switches to RemoteExecutor
log	LogLevel[] | LogDefinition[]	Log subscription
transactionOptions	{ maxWait, timeout, isolationLevel }	Defaults for interactive transactions
omit	OmitConfig	Per-model field omission
comments	SqlCommenterPlugin[]	SQL Commenter plugins
__internal	unknown	Reserved escape hatch for Prisma's own tooling

PrismaConfigInternal

The parsed shape of prisma.config.ts. Loaded by @prisma/config. See PrismaConfigInternal.

Provider

'mysql' | 'postgres' | 'sqlite' | 'sqlserver'. Defined in packages/driver-adapter-utils/src/types.ts. Note this is the adapter-layer spelling — the schema-layer provider names also include mongodb and cockroachdb, which the adapter layer subsumes under postgres.

MappedError

Normalized error shape from a driver adapter. Defined in packages/driver-adapter-utils/src/types.ts. See MappedError.

SqlQuery

The query payload an adapter receives:

• sql: string
• args: ArgArray
• argTypes?: ArgType[]

Defined in packages/driver-adapter-utils/src/types.ts.

SqlQueryable / SqlDriverAdapter / Transaction

Driver adapter contract. Defined in packages/driver-adapter-utils/src/types.ts. See SqlQueryable / SqlDriverAdapter.

DMMF

Datamodel Meta Format types. Defined in packages/dmmf/src/. Internal — no stability guarantees.

SQL Commenter types

SqlCommenterPlugin, SqlCommenterContext, SqlCommenterQueryInfo, SqlCommenterTags. Defined in packages/sqlcommenter/src/.

Generator types

For external generators, see @prisma/generator-helper:

• DMMF
• GeneratorConfig
• GeneratorOptions
• GeneratorManifest

The generatorHandler({ onManifest, onGenerate }) helper wraps stdio for IPC.

Public client errors

Caught by user code:

• PrismaClientKnownRequestError — DB-side error mapped to a P2xxx code
• PrismaClientUnknownRequestError — Engine error without a known code
• PrismaClientRustPanicError — Schema Engine panic (rare)
• PrismaClientInitializationError — Constructor / setup failure (e.g., P2038)
• PrismaClientValidationError — User input validation failed before reaching the engine

The class hierarchy lives in packages/client/src/runtime/core/errors/.
