代码:
procedure TfrmImportPage.ImportPageToDb(QuesID: Integer);
var
QuesInfo: PQuesInfo;
ParentID: Integer;
I: Integer;
HasExcep: Boolean;
M: string;
begin
HasExcep := False;
try
for I := 0 to List.Count - 1 do

if I = 0 then
ParentID := 0
else
ParentID := QuesID;
if Notebook1.PageIndex = 1 then
begin
if QueryID.Locate('ID', StrToInt(ID), []) then
begin
if rbUpdate.Checked then
UpdateToDb(QuesInfo, ParentID);
Continue;
end;
end;
FTable.Parameters.ParamByName('FID').Value := StrToInt(ID);
FTable.Parameters.ParamByName('FRegDateTime').Value := StrToDateTime(RegDateTime);
FTable.Parameters.ParamByName('FDateTime').Value := StrToDateTime(FDateTime);
FTable.Parameters.ParamByName('FUserFrom').Value := UserFrom;
FTable.Parameters.ParamByName('FSubject').Value := Subject;

end;
try
FTable.Execute;
except
on E: Exception do
begin
HasExcep := True;
M := E.Message;
end;
end;
end;
if HasExcep then
raise Exception.Create(M);
reDetail.Lines.Clear;
reDetail.Lines.Add('成功导入！');

FTable是一个TADOCommand,
FTable的SQL语句为
InsertStr = 'Insert into letters(ID, RegDateTime, FDateTime, UserFrom, Subject, ' +
'RoomID, Content, Expert, Points, Parent, Status, GetTimes, ReplyTimes, uValue, ' +
'NeedEMail, IPAddr) Values
FID, :FRegDateTime, :FDateTime, :FUserFrom, :FSubject, ' +
':FRoomID, :FContent, :FExpert, :FPoints, :FParent, :FStatus, :FRead_N, :FReply_N, :FuValue, ' +
':FNeedEMail, :FIPAddr)';
下面是QuesInfo的结构内容，
PQuesInfo = ^TQuesInfo;
TQuesInfo = record
Id,
Subject,
UserFrom,
Points,
Fdatetime,
RegDateTime,
RoomName,
ReplyTimes,
GetTimes,
Content,
Status: string;
end;
以上这些是在线导入时保存到数据库的一部分内容，List里保存的内容是一个贴子里的
多条数据库记录。
我想在导入时会有重复的记录，我在这里没有判断，而是依靠捕获异常处理的，不知是
不是因为这个原因导致数据库变得非常大。
我再查查看。
]怪事，我刚刚导了100条纪录，数据库大小几乎没有变化，不知你们的为什么会
