데이터베이스 매크로 및 전역
The macros and globals listed below apply to ODBC-based database applications. They are not used with DAO-based applications.
Before MFC 4.2, the macros AFX_SQL_ASYNC and AFX_SQL_SYNC gave asynchronous operations an opportunity to yield time to other processes. Beginning with MFC 4.2, the implementation of these macros changed because the MFC ODBC classes used only synchronous operations. The macro AFX_ODBC_CALL was new to MFC 4.2.
Database Macros
