visual c++ - Accessing more than 4 billion rows in a 32-bit MS ODBC (C++) application -
i have 32-bit application must connect both 32 , 64 bit odbc databases. see ms odbc functions have different signatures 32 , 64 bit builds. seems imply 64-bit application can use 64-bit index. case?
in 64 bit odbc api arguments 8 bytes , 4 bytes before. however, few numbers of rows , more size of field (e.g., lob). api quote returns number of rows affected , no driver know of sets other -1 sqlrowcount on select. therefore, sqlrowcount need worry if going update/delete 2 billions rows @ once , need count of rows changed/deleted. if going update/delete 2 billion rows @ once might have greater problems whether use 32bit/64bit odbc api.
