Level 2 subroutine
Determine whether there are more result sets.
call EDSMoreResults(HSTMT_IV )
•HSTMT_IV An input integer value that indicates the statement handle.
Description
If more results are available, EDSMoreResults returns EDS_SUCCESS. If all results are processed, EDSMoreResults returns EDS_NO_DATA_FOUND. If the result of the next statement in a batch failed or an error occurred in the function, EDSMoreResults returns EDS_ERROR. If EDSMoreResults is called when there are unfetched rows or when EDSMoreResults returns EDS_NO_DATA_FOUND, it has the same effect as EDSFreeStmt with the EDS_CLOSE option for the current results set.
Return Values
EDSMoreResults returns EDS_SUCCESS, EDS_INVALID_HANDLE, EDS_ERROR, or EDS_NO_DATA_FOUND.
When EDSMoreResults returns EDS_ERROR, you can obtain an associated SQLSTATE value with more specific information by calling EDSError. The following table lists each typical SQLSTATE value and explains each one in the context of the command EDSMoreResults.
The following table lists possible SQLSTATE values:
SQL STATE |
Error |
Description |
IM001 |
Driver does not support this function |
The driver associated with the statement handle does not support the function. |
S1000 |
General error |
An error occurred for which there was no specific SQLSTATE and for which no implementation-specific SQLSTATE was defined. The error message returned by EDSError in the argument ERRORTEXT describes the error and its cause. |
S1001 |
Memory allocation failure |
The driver was unable to allocate the memory required to support execution or completion of the function. |
S1008 |
Operation cancelled |
Asynchronous processing was enabled for the statement handle. The function was called and before it completed execution, EDSCancel was called on the statement handle. Then the function was called again on the statement handle. |
S1010 |
Function |
An asynchronously executing function (not this sequence error one) was called for the statement handle and was still executing when this function was called. |
S1T00 |
Timeout expired |
The timeout period expired before the data source returned the result set. The timeout period is set through EDSSetStmtOption, EDS_QUERY_TIMEOUT. |
