QUERY_E_INVALIDQUERY

A top-level query parameter is invalid

QUERY_E_INVALIDQUERY is the failure HRESULT 0x80041601 (-2147215871 signed; 2147751425 unsigned). Its severity bit is 1, facility is 4 (FACILITY_ITF), and code is 0x1601. AllStat describes it as “Invalid parameter.”

Where the failure belongs

This result belongs to legacy Windows query execution and is returned while validating the query method, command object, dialect and argument combinations before clause-specific processing. The exact condition is: a broad API-contract failure rather than proof of malformed WHERE text. This stage matters because converting the result to a generic COM failure removes the information needed to choose the owner and retry policy.

This value belongs to the legacy Indexing Service query-execution contract. It can surface through the Indexing Service OLE DB provider or related query interfaces, but it should not be presented as a generic result from every modern Windows Search API. Current Windows Search SQL documentation can clarify related clause concepts, but it does not establish that every current search API returns this legacy query-execution constant.

Likely causes

  • a stale or transformed method and interface can make the component observe that a broad API-contract failure rather than proof of malformed WHERE text.
  • an incomplete all scalar arguments hides the distinction needed to separate this HRESULT from a later catalog or service failure.
  • changes in structure sizes between validation and execution can reproduce the result even when the user-visible input looks unchanged.
  • Retrying this result with the same query dialect GUID leaves the decisive contract violation intact.
  • This result can appear when session and command ownership disagrees with the state expected while validating the query method, command object, dialect and argument combinations before clause-specific processing.

The strongest hypothesis for it must account for the operation—validating the query method, command object, dialect and argument combinations before clause-specific processing—and the documented condition. A failed command or empty rowset is only the visible symptom; it does not identify which restriction, projection, sort, scope, timeout or catalog state violated the query contract.

Telemetry that matters

  • associate method and interface with the exact UTC timestamp and correlation identifier.
  • compare failing and known-good values for all scalar arguments under the same provider or handler version.
  • record the source and normalization path of structure sizes, not only its display form.
  • use query dialect GUID to test whether the failure belongs to parsing, execution, indexing or capability negotiation.
  • preserve session and command ownership before objects or work items are released.
  • associate provider command text and dialect with the exact UTC timestamp and correlation identifier.

Evidence for it should reflect what the component actually received. Redact private literals if necessary, but keep clause boundaries, canonical properties, parameter types, dialect and parser or provider offsets.

Verification workflow

  1. Capture method and interface and all scalar arguments at the call boundary that returns this result.
  2. confirm the operation reached validating the query method, command object, dialect and argument combinations before clause-specific processing with the intended structure sizes.
  3. perform the decisive check: identify the invalid pointer, count, flag, dialect, session relationship or stale command state.
  4. reduce the case until changing query dialect GUID alone changes the HRESULT or proves it irrelevant.
  5. apply the recovery only after verifying session and command ownership; preserve the original result for comparison.

A useful control for it changes one dimension at a time. Begin with a known-good minimal command against the same catalog and restore projection, restriction, sorting, grouping and scope one component at a time.

Safe remediation

Recreate a clean command object and correct the call contract before retrying. Retry it only after the responsible input or state changes and the previous operation has completed or been cancelled. Backoff helps only with measured transient load or timeout; it cannot repair invalid clauses, projection metadata, scopes or command state.

Avoid the wrong conclusion

It does not by itself prove catalog corruption, service outage, access denial or absence of matches; the query stage and provider records must identify the failing clause or state. Without code-specific evidence for it, the value also cannot identify which wrapper, configuration, handler or service transition introduced the condition.

How nearby codes differ

QUERY_E_INVALIDRESTRICTION, QUERY_E_INVALIDSORT and QUERY_E_INVALID_OUTPUT_COLUMN are narrower stage results. Keep the symbolic HRESULT beside the stage name in telemetry because nearby constants may require different owners, user messages and retry rules despite the same visible symptom.

Developer and administrator guidance

Retain final command text, dialect, catalog generation, parameter values, timeout, cancellation state and chained OLE DB error records. Do not log credentials or unrestricted document content. Before rebuilding the catalog or restarting the provider for it, reproduce the minimal command and preserve its chained errors.

Worked example

A wrapper supplies a nonzero sort count with a null array. The provider rejects the call before parsing, and correcting the count-pointer pair resolves it. A regression test for it should assert the decisive evidence, change only the responsible condition, and include one neighboring HRESULT so future code cannot collapse distinct failures into a generic message.
