Transfers multiple rows of double-precision, floating-point data from a column of an ODBC data source to a corresponding array in a CRecordset-derived object.
void RFX_Double_Bulk( CFieldExchange* pFX, LPCTSTR szName, double** prgDblVals, long** prgLengths );
The data source column must have an ODBC type of SQL_DOUBLE. The recordset must define a field data member of type pointer to double.
If you initialize prgDblVals and prgLengths to NULL, then the arrays they point to will be allocated automatically, with sizes equal to the rowset size.
Bulk record field exchange only transfers data from the data source to the recordset object. To make your recordset updateable, you must use the ODBC API function SQLSetPos.
