DB_S_ERRORSOCCURRED
OLE DB multiple-step operation succeeded with per-item errors
DB_S_ERRORSOCCURRED is HRESULT 265946 (0x00040EDA) from Microsoft OLE DB. AllStat describes this result as “Multiple-step operation completed with one or more errors; Check each status value.” The high-order severity bit is clear, so this is a success result, but it carries more information than plain S_OK.
A compound OLE DB operation completed, but one or more individual properties, bindings, columns, or elements reported errors that must be inspected separately.
Where the result is encountered
- This result can appear in IDBProperties::SetProperties; record the producing interface and method rather than inferring behavior from the symbolic name alone.
- This result can appear in accessor or binding creation; record the producing interface and method rather than inferring behavior from the symbolic name alone.
- It can appear in multi-property initialization and configuration; record the producing interface and method rather than inferring behavior from the symbolic name alone.
The same numeric success value can be mishandled when a wrapper exposes only a Boolean. Keep the original HRESULT until the code-specific outputs and state transition have been evaluated.
Diagnostic sequence
- capture the raw HRESULT
0x00040EDAimmediately after the returning method and record whether the caller usedSUCCEEDED,FAILED, equality testing, or exception translation. - Identify the exact owner of it: interface, method, object instance, provider or filter version, thread or apartment, and operation phase.
- Validate the decisive contract boundary for it: the consumer examines every status value and uses only the subset whose postconditions are valid.
- inspect every output parameter, count, status array, returned interface, or side effect that the method documentation associates with this success-with-information result.
- Compare the observed state before and after it; do not assume that a success severity bit means every optional sub-operation completed.
- reproduce the smallest request with the same object state and then change only the condition identified by the evidence before repeating the operation.
State boundary that must be proved
The central question for it is whether the consumer examines every status value and uses only the subset whose postconditions are valid. The HRESULT alone confirms neither unrelated work nor the quality of optional outputs.
A reliable interpretation of it names the exact method contract, the object generation, and the outputs that remain valid. This prevents a success-with-information result from being promoted to full success or demoted to a generic error.
Correct handling, retry, and recovery
Do not treat SUCCEEDED as full success. Reject the object if a required element failed; otherwise continue with a clearly documented reduced configuration.
Retry it only when the recorded state can change the documented outcome. Repeating the same call is inappropriate for a stable end marker, cancellation, unsupported format, adjusted property, or partial result whose completed side effects have not been reconciled.
Evidence and telemetry to preserve
- preserve overall HRESULT.
- preserve DBPROPSTATUS, DBBINDSTATUS, or other element statuses.
- preserve provider error records.
- preserve required versus optional flags.
- preserve effective object state after the call.
Also record db_s_errorsoccurred_operation, db_s_errorsoccurred_object, db_s_errorsoccurred_state_before, db_s_errorsoccurred_state_after, UTC time, process and thread identifiers, and a correlation ID. Keep secrets out of logs while retaining GUIDs, CLSIDs, media subtypes, property IDs, row identities, and hashes needed to distinguish objects.
Difference from nearby HRESULT values
DB_E_ERRORSOCCURRED has failure severity for a multiple-step operation; it indicates the overall call still returned a usable success state with errors in elements.
This distinction determines whether the caller should consume partial outputs, stop iteration, wait, reconfigure, notify the user, or perform no error recovery at all.
Developer and administrator guidance
Application telemetry should separate terminal failure, ordinary success, partial completion, continuation, cancellation, and warning-like success. Support bundles should contain the smallest reproducible call and the effective configuration seen by the owning component.
A support report for it should include decimal 265946, hexadecimal 0x00040EDA, the AllStat meaning, the owning API, and the first detailed status or output that explains why the method did not return ordinary S_OK.
Practical validation scenario
A data source sets ten initialization properties. Eight succeed, one optional property is unsupported, and one required security property fails; the application inspects statuses and refuses to initialize despite success severity.
The negative test should preserve the condition that produces it; the recovery test should alter only that condition and verify the final state as well as the HRESULT.
