DB_E_ERRORSINCOMMAND
Meaning
Windows documents DB_E_ERRORSINCOMMAND as “One or more errors occurred during processing of command”. Here, the provider detects syntax or semantic errors while processing the command text or command tree.
Relevant OLE DB contract
This result must be interpreted against this contract: an OLE DB command moves through explicit states: command definition, properties and parameters are established before optional preparation and execution; dialect, query-tree and optimizer contracts are provider-specific and should be inferred only from reported capabilities.
Specific conditions that produce the result
- Cause 1: the command contains invalid syntax for the selected dialect.
- Cause 2: a referenced table, column or function is not valid in that command context.
- Cause 3: parameter markers or expressions appear where the provider dialect does not allow them.
Evidence to collect before changing the system
When it involves command text, parameter values, object names and query-plan details, record types, lengths, hashes or redacted identifiers instead of secrets or full business data.
- Evidence 1: the dialect GUID and a protected hash or redacted form of command text.
- Evidence 2: all OLE DB error records including native database codes and positions.
- Evidence 3: the schema/catalog context and parameter metadata used during parsing.
Corrective actions
- Action 1: correct the command using the diagnostics from the first provider error record.
- Action 2: validate identifiers against the active catalog and schema.
- Action 3: do not reduce the result to a generic database failure when line or token information is available.
Retry and recovery policy
Retry rule: retry after changing the command or its schema context; identical command text will reproduce the parse or semantic error.
Practical incident
A query generator quotes an identifier using syntax from another dialect; preserving the provider's token-position error makes the fix obvious and removes it.
Difference from related HRESULT values
DB_E_DIALECTNOTSUPPORTED rejects the dialect itself, while DB_E_ERRORSINCOMMAND means the chosen dialect was accepted but the command is invalid within it.
