SQL Server Message Results
The following Transact-SQL statements do not generate SQL Server Native Client OLE DB provider rowsets or a count of affected rows when executed:
PRINT
RAISERROR with a severity of 10 or lower
DBCC
SET SHOWPLAN
SET STATISTICS
These statements either return one or more informational messages or cause SQL Server to return informational messages in place of rowset or count results. On successful execution, the SQL Server Native Client OLE DB provider returns S_OK, and the messages are available to the SQL Server Native Client OLE DB provider consumer.
The SQL Server Native Client OLE DB provider returns S_OK and has one or more informational messages available following the execution of many Transact-SQL statements or the consumer execution of a SQL Server Native Client OLE DB provider member function.
The SQL Server Native Client OLE DB provider consumer allowing dynamic specification of query text should check error interfaces after every member function execution regardless of the value of the return code, the presence or absence of a returned IRowset or IMultipleResults interface reference, or a count of affected rows.
