DB_E_INTEGRITYVIOLATION

Value violated the integrity constraints for a column or table

Exact value and interpretation

DB_E_INTEGRITYVIOLATION has the unsigned 32-bit value 2147749423 (0x80040E2F) and the signed representation -2147217873. AllStat defines the result as “Value violated the integrity constraints for a column or table”. In the concrete failure represented here, an inserted or updated value violates an integrity constraint on a column or table.

The high bit is set for DB_E_INTEGRITYVIOLATION, 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 3631 (0x0E2F). Those bit fields place DB_E_INTEGRITYVIOLATION in an interface-defined family, but they do not reveal the provider, object identity, method, rowset generation or command state that produced it.

Specific conditions that produce this result

OLE DB contract boundary

DB_E_INTEGRITYVIOLATION must be interpreted against this contract: OLE DB schema contracts combine DBIDs, provider type metadata, column attributes, constraints and locale rules; current provider metadata is authoritative; cached ordinals or type assumptions can become invalid after a schema or command change.

Start with the table, column, parameter or schema object named by the failing definition or data operation when investigating DB_E_INTEGRITYVIOLATION. Preserve DB_E_INTEGRITYVIOLATION 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_INTEGRITYVIOLATION 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_INTEGRITYVIOLATION: an inserted or updated value violates an integrity constraint on a column or table.
  3. For DB_E_INTEGRITYVIOLATION, compare the live command, rowset, accessor or schema state with the metadata and properties actually granted by the provider.
  4. For DB_E_INTEGRITYVIOLATION, 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_INTEGRITYVIOLATION, reproduce the issue with the smallest command, rowset or definition operation that preserves the same contract boundary.
  6. For DB_E_INTEGRITYVIOLATION, apply one evidence-backed correction, then verify that the operation succeeds and does not merely change into a nearby HRESULT.

Evidence to collect before changing the system

A useful DB_E_INTEGRITYVIOLATION 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_INTEGRITYVIOLATION involves table names, column values, keys, constraints and provider-specific type declarations, record types, lengths, hashes or redacted identifiers instead of secrets or full business data.

Corrective actions

Practical incident

Two workers insert the same natural key after both pass an application-side existence check; handling the unique constraint result prevents blind retries of DB_E_INTEGRITYVIOLATION. The diagnostic value comes from retaining DB_E_INTEGRITYVIOLATION together with the failing interface and object state, not from reducing every provider result to “database error”.

Retry and recovery policy

Retry rule for DB_E_INTEGRITYVIOLATION: retry only after the constrained values or referenced data change. A safe DB_E_INTEGRITYVIOLATION retry must use a changed input, object generation, provider capability or state transition. If the call returning DB_E_INTEGRITYVIOLATION could have created, updated, deleted or copied data, determine partial completion before replaying it.

For DB_E_INTEGRITYVIOLATION, use bounded retries and preserve cancellation. For DB_E_INTEGRITYVIOLATION, 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_SCHEMAVIOLATION is a broader schema mismatch, while DB_E_INTEGRITYVIOLATION specifically identifies a column or table integrity constraint. Keep these outcomes separate in telemetry and user-facing remediation because DB_E_INTEGRITYVIOLATION requires a different next action.

Implementation guidance

Code handling DB_E_INTEGRITYVIOLATION 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_INTEGRITYVIOLATION, handles such as HACCESSOR, HROW, HCHAPTER and provider-specific region tokens must never be treated as portable integers across object lifetimes.

When DB_E_INTEGRITYVIOLATION 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_INTEGRITYVIOLATION, do not log passwords, access tokens, complete SQL text or unrestricted row values merely to make the event easier to search.
