DB_E_ERRORSOCCURRED

Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done

Exact value and interpretation

DB_E_ERRORSOCCURRED has the unsigned 32-bit value 2147749409 (0x80040E21) and the signed representation -2147217887. AllStat defines the result as “Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done”. In the concrete failure represented here, every element of a multi-step OLE DB operation failed and no requested work was performed.

The high bit is set for DB_E_ERRORSOCCURRED, so it is a failure HRESULT rather than a success or informational status. Its facility field is 4 (FACILITY_ITF) and its low code is 3617 (0x0E21). Those bit fields place DB_E_ERRORSOCCURRED in an interface-defined family, but they do not reveal the provider, object identity, method, rowset generation or command state that produced it.

OLE DB contract boundary

DB_E_ERRORSOCCURRED must be interpreted against this contract: OLE DB error objects can contain multiple records and per-element status arrays; the aggregate HRESULT is only the entry point; consumers need the error object captured immediately after the failing provider call.

Start with the current thread error object, its record array and the provider method that installed it when investigating DB_E_ERRORSOCCURRED. Preserve DB_E_ERRORSOCCURRED before ADO, ATL, .NET, a database abstraction layer or an application exception replaces it with a generic message; the exact interface and method matter because one OLE DB object can expose several contracts with different preconditions.

Diagnostic sequence

  1. Capture DB_E_ERRORSOCCURRED immediately at the native OLE DB return and obtain the current OLE DB error object before another COM call replaces thread error information.
  2. Identify the exact stage for DB_E_ERRORSOCCURRED: every element of a multi-step OLE DB operation failed and no requested work was performed.
  3. For DB_E_ERRORSOCCURRED, compare the live command, rowset, accessor or schema state with the metadata and properties actually granted by the provider.
  4. For DB_E_ERRORSOCCURRED, inspect per-binding, per-property, per-row or per-record statuses whenever the method supplies them; the aggregate result may not identify the rejected element.
  5. For DB_E_ERRORSOCCURRED, reproduce the issue with the smallest command, rowset or definition operation that preserves the same contract boundary.
  6. For DB_E_ERRORSOCCURRED, apply one evidence-backed correction, then verify that the operation succeeds and does not merely change into a nearby HRESULT.

Specific conditions that produce this result

  • Cause 1 for DB_E_ERRORSOCCURRED: all property settings, bindings, parameter names or rows were rejected.
  • Cause 2 for DB_E_ERRORSOCCURRED: the consumer checked only the aggregate HRESULT and ignored per-element status arrays.
  • Cause 3 for DB_E_ERRORSOCCURRED: provider error records contain multiple independent failures from the same call.

Evidence to collect before changing the system

A useful DB_E_ERRORSOCCURRED record includes provider CLSID and version, process architecture, interface and method, COM apartment and thread, object correlation ID, transaction state, and the first preceding HRESULT. When DB_E_ERRORSOCCURRED involves provider descriptions, native database messages, command fragments and row values, record types, lengths, hashes or redacted identifiers instead of secrets or full business data.

  • Evidence 1 for DB_E_ERRORSOCCURRED: the complete per-element status array in original order.
  • Evidence 2 for DB_E_ERRORSOCCURRED: all records from the current OLE DB error object.
  • Evidence 3 for DB_E_ERRORSOCCURRED: the method inputs correlated to each failed element.

Corrective actions

  • Action 1 for DB_E_ERRORSOCCURRED: inspect and report every element status before changing the request.
  • Action 2 for DB_E_ERRORSOCCURRED: correct the individual properties, bindings or rows indicated by those statuses.
  • Action 3 for DB_E_ERRORSOCCURRED: clear stale thread error information before the next provider call.

Retry and recovery policy

Retry rule for DB_E_ERRORSOCCURRED: retry only after at least one failed element is corrected; resubmitting the identical multi-step request repeats the aggregate failure. A safe DB_E_ERRORSOCCURRED retry must use a changed input, object generation, provider capability or state transition. If the call returning DB_E_ERRORSOCCURRED could have created, updated, deleted or copied data, determine partial completion before replaying it.

For DB_E_ERRORSOCCURRED, use bounded retries and preserve cancellation. For DB_E_ERRORSOCCURRED, configuration and contract failures should normally fail fast; concurrency, resource or transient state failures may justify retry only after their stated precondition changes.

Difference from related HRESULT values

DB_S_ERRORSOCCURRED means some elements succeeded, while DB_E_ERRORSOCCURRED means all relevant elements failed and no work was done. Keep these outcomes separate in telemetry and user-facing remediation because DB_E_ERRORSOCCURRED requires a different next action.

Practical incident

A property setup call returns DB_E_ERRORSOCCURRED because every requested property is unsupported, but the wrapper logs only the HRESULT; preserving DBPROPSTATUS values exposes the real cause. The diagnostic value comes from retaining DB_E_ERRORSOCCURRED together with the failing interface and object state, not from reducing every provider result to “database error”.

Implementation guidance

Code handling DB_E_ERRORSOCCURRED should release OLE DB resources in ownership order, preserve every provider error record, and log granted properties rather than only requested properties. When handling DB_E_ERRORSOCCURRED, handles such as HACCESSOR, HROW, HCHAPTER and provider-specific region tokens must never be treated as portable integers across object lifetimes.

When DB_E_ERRORSOCCURRED crosses an abstraction boundary, attach a stable correlation ID and structured fields for the native HRESULT, provider source, interface IID, method, object generation and operation phase. For DB_E_ERRORSOCCURRED, do not log passwords, access tokens, complete SQL text or unrestricted row values merely to make the event easier to search.
