DB_E_NOPROVIDERSREGISTERED

No OLE DB providers of this source type are registered

Exact value and result class

DB_E_NOPROVIDERSREGISTERED has unsigned value 2147749492 (0x80040E74) and signed 32-bit value -2147217804. AllStat describes it as “No OLE DB providers of this source type are registered”. In this result, provider enumeration for the requested source type finds no registered OLE DB providers.

The high bit is set, so DB_E_NOPROVIDERSREGISTERED is a failure HRESULT. Its facility is 4 (FACILITY_ITF) and its low code is 3700 (0x0E74). For DB_E_NOPROVIDERSREGISTERED, these fields identify an interface-defined result family; they do not identify the provider instance, method, object generation or partial effects.

Contract boundary

For DB_E_NOPROVIDERSREGISTERED, OLE DB initialization strings select a provider and set initialization properties before IDBInitialize::Initialize. For DB_E_NOPROVIDERSREGISTERED, syntax errors, missing provider registration and a provider mismatch are distinct from server connectivity and authentication failures.

Investigation of DB_E_NOPROVIDERSREGISTERED should start with the uninitialized data source object, parsed initialization properties and provider CLSID or ProgID. Capture DB_E_NOPROVIDERSREGISTERED before ADO, ATL, .NET or a database abstraction layer replaces the native HRESULT with a generic exception.

Conditions that specifically lead to this result

  • Cause 1 for DB_E_NOPROVIDERSREGISTERED: the required provider is not installed.
  • Cause 2 for DB_E_NOPROVIDERSREGISTERED: registration is missing for the current process architecture.
  • Cause 3 for DB_E_NOPROVIDERSREGISTERED: the requested source type has no compatible provider.

Evidence to collect

A useful DB_E_NOPROVIDERSREGISTERED event records provider CLSID and version, process architecture, interface IID and method, object correlation ID, transaction state and the immediately preceding HRESULT. When recording DB_E_NOPROVIDERSREGISTERED data involving passwords, tokens, server names and complete connection strings, use types, lengths, hashes or redacted identifiers rather than secrets or complete business data.

  • Evidence 1 for DB_E_NOPROVIDERSREGISTERED: requested source type.
  • Evidence 2 for DB_E_NOPROVIDERSREGISTERED: 32-bit or 64-bit process architecture.
  • Evidence 3 for DB_E_NOPROVIDERSREGISTERED: provider CLSID and registry presence.

Diagnostic sequence

  1. Capture raw 0x80040E74 and symbolic DB_E_NOPROVIDERSREGISTERED at the native call boundary.
  2. Identify the exact failing stage for DB_E_NOPROVIDERSREGISTERED: provider enumeration for the requested source type finds no registered OLE DB providers.
  3. Retrieve all OLE DB error records for DB_E_NOPROVIDERSREGISTERED before another COM call replaces thread error information.
  4. Compare the live object state and provider-granted capabilities with the input that produced DB_E_NOPROVIDERSREGISTERED.
  5. Reduce the DB_E_NOPROVIDERSREGISTERED operation to the smallest case that preserves the same init contract.
  6. Apply one evidence-backed correction for DB_E_NOPROVIDERSREGISTERED and verify that the result is not merely replaced by a neighboring HRESULT.

Corrective actions

  • Action 1 for DB_E_NOPROVIDERSREGISTERED: install and register a supported provider.
  • Action 2 for DB_E_NOPROVIDERSREGISTERED: match application architecture to provider registration.
  • Action 3 for DB_E_NOPROVIDERSREGISTERED: surface a clear deployment prerequisite instead of retrying discovery.

Retry and recovery

Retry rule for DB_E_NOPROVIDERSREGISTERED: retry after a compatible provider has been installed and registered. A DB_E_NOPROVIDERSREGISTERED retry is safe only when the relevant input, object generation, capability or external state has changed. Before replaying a modifying call that returned DB_E_NOPROVIDERSREGISTERED, determine whether rows, schema objects or URL resources were partially created or changed.

Do not turn DB_E_NOPROVIDERSREGISTERED into an unbounded retry loop. Preserve cancellation for DB_E_NOPROVIDERSREGISTERED and use a fresh provider object when the failed call may have left local state ambiguous.

Practical scenario

A 64-bit service cannot see a provider registered only for 32-bit clients; installing the matching build restores enumeration. Keeping DB_E_NOPROVIDERSREGISTERED with the method and object state makes this scenario diagnosable instead of reducing it to “database error”.

Difference from nearby HRESULT values

REGDB_E_CLASSNOTREG is a general COM class registration failure, while DB_E_NOPROVIDERSREGISTERED is OLE DB provider discovery for a source type. Telemetry and remediation for DB_E_NOPROVIDERSREGISTERED should keep these outcomes distinct.

Developer and operations guidance

Code handling DB_E_NOPROVIDERSREGISTERED should release COM objects in ownership order, retain per-row, per-column or per-property statuses, and log granted capabilities rather than only requested options. While handling DB_E_NOPROVIDERSREGISTERED, opaque values such as HACCESSOR, HROW, HCHAPTER, DBID components and provider handles must remain scoped to the object that issued them.

Operational dashboards for DB_E_NOPROVIDERSREGISTERED should group by provider version, interface, method and normalized failure stage. A DB_E_NOPROVIDERSREGISTERED event must not expose passwords, tokens, full connection strings, unrestricted command text or raw row contents.
