　　6、读取记录域

　　代码：

boolean GetRecordByID(IDatabase * pIDatabase, uint16 u16RecID)
{
IDBRecord * pIDBRec1 = NULL;
AEEDBFieldType fType;
AEEDBFieldName fName;
uint16 fLen;
byte * data = NULL;;

// This will reset the record Index to 0.
IDATABASE_Reset (pIDatabase);

// IDATABASE_GetRecordByID: returns a pointer to the record whose
// record ID is specified.
pIDBRec1 = IDATABASE_GetRecordByID (pIDatabase, u16RecID);

// Get the raw data of the field
for(;;)
{
// Get record 1 first field and display it
fType = IDBRECORD_NextField (pIDBRec1, &fName, &fLen);

data = IDBRECORD_GetField (pIDBRec1, &fName, &fType, &fLen);
if (data != NULL)
{
switch(fName)
{
case AEEDBFIELD_FIRSTNAME;
break;
case AEEDBFIELD_LASTNAME;
break;
case AEEDBFIELD_ADDRESS;
break;
default:
break;
}
}
else
{
break; //break for
}
}

// Now remove record 1.
IDBRECORD_Release(pIDBRec1);
return TRUE;
}
