SQLMoreResults() determines whether there is more information available on the statement handle which has been associated with a stored procedure that is returning result sets.
SQLRETURN SQLMoreResults (SQLHSTMT StatementHandle);
| Data type | Argument | Use | Description |
|---|---|---|---|
| SQLHSTMT | StatementHandle | input | Statement handle |
This function is used to return multiple results that are set in a sequential manner upon the processing of a stored procedure that contains SQL queries. The cursors have been left open so that the result sets remain accessible when the stored procedure has finished processing.
After completely processing the first result set, the application can call SQLMoreResults() to determine if another result set is available. If the current result set has unfetched rows, SQLMoreResults() discards them by closing the cursor and, if another result set is available, returns SQL_SUCCESS.
If all the result sets have been processed, SQLMoreResults() returns SQL_NO_DATA_FOUND.
If SQLFreeStmt() is called with the SQL_CLOSE or SQL_DROP option, all pending result sets on this statement handle are discarded.
| SQLSTATE | Description | Explanation |
|---|---|---|
| 40003 08S01 | Communication link failure | The communication link between the application and data source fails before the function is completed. |
| 58004 | Unexpected system failure | Unrecoverable system error. |
| HY001 | Memory allocation failure | DB2® UDB CLI is unable to allocate memory required to support the processing or completion of the function. |
| HY010 | Function sequence error | The function is called while in a data-at-processing (SQLParamData(), SQLPutData()) operation. |
| HY013 | Unexpected memory handling error | DB2 UDB CLI is unable to access memory required to support the processing or completion of the function. |
| HY021 | Internal descriptor that is not valid | The internal descriptor cannot be addressed or allocated, or it contains a value that is not valid. |
| HYT00 | Timeout expired |
In addition SQLMoreResults() can return the SQLSTATEs associated with SQLExecute().
The ODBC specification of SQLMoreResults() also allow counts associated with the processing of parameterized INSERT, UPDATE, and DELETE statements with arrays of input parameter values to be returned. However, DB2 UDB CLI does not support the return of such count information.
