The AFX_SQL_SYNC macro simply calls the function SQLFunc.
AFX_SQL_SYNC(SQLFunc )
Parameters
- SQLFunc
An ODBC API function. For more information about these functions, see the Windows SDK.
Remarks
Use this macro to call ODBC API functions that will not return SQL_STILL_EXECUTING.
Before calling AFX_SQL_SYNC, you must declare a variable, nRetCode, of type RETCODE. You can check the value of nRetCode after the macro call.
Note that the implementation of AFX_SQL_SYNC changed in MFC 4.2. Because checking the server status was no longer required, AFX_SQL_SYNC simply assigns a value to nRetCode. For example, instead of making the call
AFX_SQL_SYNC(::SQLGetInfo(m_dbCust.m_hdbc, SQL_ODBC_SQL_CONFORMANCE,
&nValue, sizeof(nValue), &cbValue));
you can simply make the assignment
nRetCode = ::SQLGetInfo(m_dbCust.m_hdbc, SQL_ODBC_SQL_CONFORMANCE,
&nValue, sizeof(nValue), &cbValue);
