[Microsoft][ODBC Driver Manager] Function sequence error SQLSTATE: HY010

int main()

SQLRETURN rc;
SQLRETURN rc2;
SQLCHAR SqlState[6], SQLStmt[100], Msg[SQL_MAX_MESSAGE_LENGTH];

I got the above "[Microsoft][ODBC Driver Manager] Function sequence error SQLSTATE: HY010" error when I tried to create connection handle.When I set the environment attribute SQL_ATTR_ODBC_VERSION to ODBC3.0
