【问题描述】*：32位客户端通过ODBC驱动连接64位达梦8数据库使用DISTINCT关键字查询并使用静态游标程序在MoveNext时异常，示例代码如下：

#import"msado20.tlb" rename_namespace(“ADODB”) rename(“EOF”, “adoEOF”)

int _tmain(int argc, _TCHAR* argv[])
{
ADODB::_ConnectionPtr spCon = NULL;
ADODB::_RecordsetPtr spRst = NULL;
_variant_t vtVal;

CoInitialize(NULL);

HRESULT hr = spCon.CreateInstance(__uuidof(ADODB::Connection));
spCon->Open(_T("DRIVER=DM8 ODBC DRIVER;Server=localhost;TCP_PORT=5236;UID=YXSXK;PWD=YXSXKYXSXK"), _T(""), _T(""), ADODB::adConnectUnspecified);

spCon->raw_Execute(_T("CREATE TABLE TEST (NAME NVARCHAR(128),CLASS NVARCHAR(64))"),NULL,ADODB::adExecuteNoRecords,NULL);
spCon->Execute(_T("INSERT INTO TEST(NAME,CLASS) VALUES('NAME1','CLASS1')"),NULL,ADODB::adExecuteNoRecords);
spCon->Execute(_T("INSERT INTO TEST(NAME,CLASS) VALUES('NAME2','CLASS2')"),NULL,ADODB::adExecuteNoRecords);

hr = spRst.CreateInstance(__uuidof(ADODB::Recordset));
spRst->Open(_bstr_t(_T("SELECT DISTINCT CLASS FROM TEST")), _variant_t(spCon,true), ADODB::adOpenStatic, ADODB::adLockOptimistic, ADODB::adCmdText);
while(VARIANT_FALSE == spRst->adoEOF)
{
	vtVal = spRst->GetCollect(_T("CLASS"));
	spRst->MoveNext();//程序运行到这里就异常了
}

CoUninitialize();

return 0;
