DB_E_MULTIPLESTATEMENTS
Meaning
Windows documents DB_E_MULTIPLESTATEMENTS as “Multiple-statement commands are not supported by this provider”. Here, the command text contains multiple statements but the provider accepts only a single statement per command object.
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.
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 and redacted statement boundaries.
- Evidence 2: provider capability for multiple result sets or batched commands.
- Evidence 3: the command generator stage that combined statements.
Specific conditions that produce it
- Cause 1: the text includes two statements separated by a delimiter.
- Cause 2: a migration or batching layer concatenates commands for a provider without batch support.
- Cause 3: a trailing administrative statement is appended to a query.
Retry and recovery policy
Retry rule: retry after reducing the command to one supported statement or selecting a provider-supported batch contract.
Corrective actions
- Action 1: execute statements separately in a controlled transaction.
- Action 2: use a provider-supported batch mechanism only when documented.
- Action 3: avoid naive delimiter splitting that ignores literals and comments.
Practical incident
A cleanup statement is appended after a SELECT for a provider that only accepts one statement; issuing two commands removes it.
Difference from related HRESULT values
DB_E_ERRORSINCOMMAND means a statement is invalid in the accepted command contract, while DB_E_MULTIPLESTATEMENTS specifically rejects the presence of more than one statement.
