DB_E_BADHRESULT

HRESULT is invalid

Exact value and result class

DB_E_BADHRESULT has unsigned value 2147749464 (0x80040E58) and signed 32-bit value -2147217832. AllStat describes it as “HRESULT is invalid”. In this result, provider-side OLE DB error metadata contains an HRESULT that the error-object machinery considers invalid; the public contract does not identify a consumer data method.

The high bit is set, so DB_E_BADHRESULT is a failure HRESULT. Its facility is 4 (FACILITY_ITF) and its low code is 3672 (0x0E58). For DB_E_BADHRESULT, 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_BADHRESULT, OLE DB error objects can contain multiple records. For DB_E_BADHRESULT, provider-side error construction combines an HRESULT, lookup ID, optional parameters, custom error object and dynamic-error lifetime; each identifier has a different namespace and validation rule.

Investigation of DB_E_BADHRESULT should start with the provider code building or resolving the OLE DB error record and the exact IErrorRecords operation. Capture DB_E_BADHRESULT before ADO, ATL, .NET or a database abstraction layer replaces the native HRESULT with a generic exception.

Diagnostic sequence

  1. Capture raw 0x80040E58 and symbolic DB_E_BADHRESULT at the native call boundary.
  2. Identify the exact failing stage for DB_E_BADHRESULT: provider-side OLE DB error metadata contains an HRESULT that the error-object machinery considers invalid; the public contract does not identify a consumer data method.
  3. Retrieve all OLE DB error records for DB_E_BADHRESULT 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_BADHRESULT.
  5. Reduce the DB_E_BADHRESULT operation to the smallest case that preserves the same error contract.
  6. Apply one evidence-backed correction for DB_E_BADHRESULT and verify that the result is not merely replaced by a neighboring HRESULT.

Conditions that specifically lead to this result

  • Cause 1 for DB_E_BADHRESULT: an error record is built with a nonconforming return value.
  • Cause 2 for DB_E_BADHRESULT: memory corruption alters ERRORINFO.hrError.
  • Cause 3 for DB_E_BADHRESULT: a provider mixes a native status code with an HRESULT field without conversion.

Evidence to collect

A useful DB_E_BADHRESULT 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_BADHRESULT data involving native database messages, error parameters and command fragments, use types, lengths, hashes or redacted identifiers rather than secrets or complete business data.

  • Evidence 1 for DB_E_BADHRESULT: the raw ERRORINFO structure before insertion.
  • Evidence 2 for DB_E_BADHRESULT: the provider code path constructing the error record.
  • Evidence 3 for DB_E_BADHRESULT: the original native status and conversion function.

Corrective actions

  • Action 1 for DB_E_BADHRESULT: store a valid HRESULT in ERRORINFO.hrError.
  • Action 2 for DB_E_BADHRESULT: validate provider-generated error records in tests.
  • Action 3 for DB_E_BADHRESULT: keep native status in provider-specific fields rather than overloading HRESULT.

Retry and recovery

Retry rule for DB_E_BADHRESULT: retry only after correcting provider error-record construction; repeating the data operation is not a remedy. A DB_E_BADHRESULT 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_BADHRESULT, determine whether rows, schema objects or URL resources were partially created or changed.

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

Difference from nearby HRESULT values

DB_E_BADLOOKUPID concerns the message lookup key, while DB_E_BADHRESULT concerns the return-code field itself. Telemetry and remediation for DB_E_BADHRESULT should keep these outcomes distinct.

Practical scenario

A custom provider writes a database integer code directly into hrError; mapping it to a documented HRESULT restores error lookup. Keeping DB_E_BADHRESULT with the method and object state makes this scenario diagnosable instead of reducing it to “database error”.

Developer and operations guidance

Code handling DB_E_BADHRESULT 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_BADHRESULT, 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_BADHRESULT should group by provider version, interface, method and normalized failure stage. A DB_E_BADHRESULT event must not expose passwords, tokens, full connection strings, unrestricted command text or raw row contents.
