DB_E_BADDYNAMICERRORID

Meaning

Windows documents DB_E_BADDYNAMICERRORID as “DynamicError ID is invalid”. In this case, an error record refers to an invalid dynamic-error identifier used by the provider lookup service for runtime-created error information.

Relevant contract

OLE DB error objects can contain multiple records. 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 this result should start with the provider code building or resolving the OLE DB error record and the exact IErrorRecords operation.

Conditions that specifically lead to the result

Cause 1: the dynamic ID was already released.
Cause 2: the ID belongs to another lookup-service instance.
Cause 3: provider code reused an uninitialized dynamic-error value.

Evidence to collect

When recording diagnostic 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: dwDynamicErrorID at record creation and release.
Evidence 2: lookup-service instance identity.
Evidence 3: ordering of AddErrorRecord and IErrorLookup::ReleaseErrors.

Diagnostic sequence

Identify the exact failing stage: an error record refers to an invalid dynamic-error identifier used by the provider lookup service for runtime-created error information.

Corrective actions

Action 1: allocate dynamic IDs through one owning lookup service.
Action 2: release dynamic information only when the error object lifetime ends.
Action 3: use zero for records that do not require dynamic lookup state.

Retry and recovery

Retry rule: retry only after reconstructing the error object with a valid live dynamic ID.

Practical scenario

A provider frees dynamic message data before the OLE DB error object is released; transferring lifetime ownership prevents the invalid ID.

Difference from nearby HRESULT values

DB_E_BADLOOKUPID identifies an invalid message selector, while DB_E_BADDYNAMICERRORID identifies invalid runtime error storage.
