DB_E_BADSTATUSVALUE
Exact value and interpretation
DB_E_BADSTATUSVALUE has the unsigned 32-bit value 2147749416 (0x80040E28) and the signed representation -2147217880. AllStat defines the result as “Status flag was neither DBCOLUMNSTATUS_OK nor DBCOLUMNSTATUS_ISNULL”. In the concrete failure represented here, a write or parameter binding supplies a DBSTATUS value other than the statuses accepted for input.
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 3624 (0x0E28). 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.
OLE DB contract boundary
This result must be interpreted against this contract: OLE DB accessors describe how columns or parameters map to a consumer buffer; an HACCESSOR is object-scoped, reference-counted and inseparable from its DBBINDING layout, bound parts, data types, offsets and ownership rules.
Start with the command or rowset that created the accessor and the consumer buffer passed to the failing method 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 the result
- Cause 1 for it: the consumer passes an output-only error status back into SetData.
- Cause 2 for it: an uninitialized status field contains an arbitrary value.
- Cause 3 for it: the binding does not include status storage consistently with the buffer layout.
Evidence to collect before changing the system
A useful it 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 parameter values, row contents, connection-specific identifiers and long-data buffers, record types, lengths, hashes or redacted identifiers instead of secrets or full business data.
- Evidence 1 for it: the DBSTATUS value and binding ordinal.
- Evidence 2 for it: which DBPART flags are bound for value, length and status.
- Evidence 3 for it: the buffer initialization path before the provider call.
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: a write or parameter binding supplies a DBSTATUS value other than the statuses accepted for input.
- 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: initialize every bound status field explicitly.
- Action 2 for it: use DBSTATUS_S_OK or DBSTATUS_S_ISNULL only where the method contract permits.
- Action 3 for it: do not recycle output status arrays as input without normalization.
Retry and recovery policy
Retry rule for it: retry after correcting the status fields and validating the buffer layout. 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.
Practical incident
A bulk updater reuses a GetData buffer containing DBSTATUS_E_CANTCONVERTVALUE as SetData input; resetting statuses to valid input values removes 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”.
Difference from related HRESULT values
DB_E_BADBINDINFO concerns the binding description, while it concerns a status value placed in an otherwise addressable binding buffer. Keep these outcomes separate in telemetry and user-facing remediation because it requires a different next action.
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.
