DB_E_BADROWHANDLE
Exact value and interpretation
DB_E_BADROWHANDLE has the unsigned 32-bit value 2147749380 (0x80040E04) and the signed representation -2147217916. AllStat defines the result as “Row handle is invalid”. In the concrete failure represented here, an OLE DB rowset method receives an HROW that is not valid for that rowset.
The high bit is set for it, 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 3588 (0x0E04). Those bit fields place this result in an interface-defined family, but they do not reveal the provider, object identity, method, rowset generation or command state that produced it.
Evidence to collect before changing the system
A useful this result 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 it involves row values, bookmarks, keys and query parameters, record types, lengths, hashes or redacted identifiers instead of secrets or full business data.
- Evidence 1 for it: the rowset identity, HROW value and method that rejected it.
- Evidence 2 for it: the GetNextRows or InsertRow call that produced the handle.
- Evidence 3 for it: ReleaseRows, deletion and rowset-lifetime events preceding the failure.
OLE DB contract boundary
This result must be interpreted against this contract: OLE DB rowsets own HROW values, fetch position, granted properties and visibility rules; row handles, bookmarks, update state and navigation capabilities remain valid only under the lifetime and generation that produced them.
Start with the current rowset instance, its granted properties and the exact row or position token used by the consumer when investigating this result. Preserve it 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.
Specific conditions that produce it
- Cause 1 for it: the row handle was already released.
- Cause 2 for it: the handle belongs to another rowset instance.
- Cause 3 for it: the row was invalidated by deletion, restart, resynchronization or rowset replacement.
Diagnostic sequence
- Capture it immediately at the native OLE DB return and obtain the current OLE DB error object before another COM call replaces thread error information.
- Identify the exact stage for it: an OLE DB rowset method receives an HROW that is not valid for that rowset.
- compare the live command, rowset, accessor or schema state with the metadata and properties actually granted by the provider.
- 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.
- reproduce the issue with the smallest command, rowset or definition operation that preserves the same contract boundary.
- apply one evidence-backed correction, then verify that the operation succeeds and does not merely change into a nearby HRESULT.
Corrective actions
- Action 1 for it: keep HROW values scoped to the rowset that created them.
- Action 2 for it: remove handles from caches immediately after ReleaseRows.
- Action 3 for it: reacquire the row after topology, transaction or rowset state changes.
Practical incident
A cache preserves HROW values across a query re-execution and later calls GetData on the new rowset; refetching the rows prevents it. The diagnostic value comes from retaining it together with the failing interface and object state, not from reducing every provider result to “database error”.
Implementation guidance
Code handling it should release OLE DB resources in ownership order, preserve every provider error record, and log granted properties rather than only requested properties. When handling it, handles such as HACCESSOR, HROW, HCHAPTER and provider-specific region tokens must never be treated as portable integers across object lifetimes.
When it 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. Do not log passwords, access tokens, complete SQL text or unrestricted row values merely to make the event easier to search.
Retry and recovery policy
Retry rule for it: retry only after fetching or inserting a fresh row handle from the current rowset. A safe it retry must use a changed input, object generation, provider capability or state transition. If the call returning it could have created, updated, deleted or copied data, determine partial completion before replaying it.
Use bounded retries and preserve cancellation. 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_E_DELETEDROW means the handle identifies a deleted row, whereas it means the handle is not valid for the receiving rowset at all. Keep these outcomes separate in telemetry and user-facing remediation because it requires a different next action.
