MD_E_INVALIDAXIS

Exact value and result class

MD_E_INVALIDAXIS has unsigned value 2147749475 (0x80040E63) and signed 32-bit value -2147217821. AllStat describes it as “Axis is invalid”. In this result, the consumer references an axis identifier or position that does not exist in the current multidimensional dataset.

The high bit is set, so this result is a failure HRESULT. Its facility is 4 (FACILITY_ITF) and its low code is 3683 (0x0E63). These fields identify an interface-defined result family; they do not identify the provider instance, method, object generation or partial effects.

Evidence to collect

A useful this result event records provider CLSID and version, process architecture, interface IID and method, object correlation ID, transaction state and the immediately preceding HRESULT. When recording it data involving member unique names, cube coordinates and calculated-measure expressions, use types, lengths, hashes or redacted identifiers rather than secrets or complete business data.

  • Evidence 1 for it: requested axis ordinal.
  • Evidence 2 for it: axis metadata returned for the current dataset.
  • Evidence 3 for it: query generation and UI mapping that selected the axis.

Contract boundary

OLE DB for OLAP models axes, tuples, coordinates and cells separately. A tuple identifies one member from each relevant hierarchy, a coordinate positions a cell across axes, and cell ordinals are valid only for the current dataset shape.

Investigation of this result should start with the dataset object, axis metadata, tuple construction and cellset generation used by the failing call. Capture it before ADO, ATL,.NET or a database abstraction layer replaces the native HRESULT with a generic exception.

Conditions that specifically lead to it

  • Cause 1 for it: the axis index exceeds the returned axis count.
  • Cause 2 for it: a slicer or filter axis is confused with a display axis.
  • Cause 3 for it: query changes removed an axis while UI state retained its index.

Diagnostic sequence

  1. Capture raw 0x80040E63 and symbolic it at the native call boundary.
  2. Identify the exact failing stage for it: the consumer references an axis identifier or position that does not exist in the current multidimensional dataset.
  3. Retrieve all OLE DB error records for it before another COM call replaces thread error information.
  4. Compare the live object state and provider-granted capabilities with the input that produced it.
  5. Reduce the operation to the smallest case that preserves the same olap contract.
  6. Apply one evidence-backed correction for it and verify that the result is not merely replaced by a neighboring HRESULT.

Corrective actions

  • Action 1 for it: enumerate axes before addressing them.
  • Action 2 for it: map axes by current metadata rather than fixed positions.
  • Action 3 for it: reset axis-dependent state after query changes.

Practical scenario

A report assumes a second display axis after a query collapses to one; checking the axis collection avoids the invalid-axis result. Keeping it with the method and object state makes this scenario diagnosable instead of reducing it to “database error”.

Developer and operations guidance

Code handling it should release COM objects in ownership order, retain per-row, per-column or per-property statuses, and log granted capabilities rather than only requested options. While handling it, opaque values such as HACCESSOR, HROW, HCHAPTER, DBID components and provider handles must remain scoped to the object that issued them.

Operational dashboards for it should group by provider version, interface, method and normalized failure stage. A it event must not expose passwords, tokens, full connection strings, unrestricted command text or raw row contents.

Retry and recovery

Retry rule for it: retry after selecting an axis reported by the current dataset. A it retry is safe only when the relevant input, object generation, capability or external state has changed. Before replaying a modifying call that returned it, determine whether rows, schema objects or URL resources were partially created or changed.

Do not turn it into an unbounded retry loop. Preserve cancellation for it and use a fresh provider object when the failed call may have left local state ambiguous.

Difference from nearby HRESULT values

MD_E_INVALIDCELLRANGE rejects cell ordinals within the cellset, while it rejects the axis reference itself. Telemetry and remediation for it should keep these outcomes distinct.
