帮忙啊。谢谢

AdoDataSet.UpdateBatch(arall)应该是对已打开的数据集进行修改后再进行成批更新吧？
没有看到你打开数据集。这是UpdateBatch在D6help中的Note:
To use batch updating, the CursorType property of the
dataset component must be either ctKeySet (the default)
or ctStatic and the LockType property must be ltBatchOptimistic.

请问
我只想insert
如何打开数据集呢

不能在关闭的数据集中执行

如何打开数据集呢？

adodataset.open//打开
.loadfromfile//打开

肯定出错，你搞错概念了。
要这样：

try
begin
-------
ADODataSet.close;
CommandText:='select * from allfile where 0=1';
ADODataSet.open;
----------------------
while not Eof(f) do
begin
Readln(F,FileItem);
AnalyzeTxt(FileItem);
with ADODataSet do
begin
--------------
insert;
FieldByName('name').asString:=name;
FieldByName......
............
post;
-----------------
// CommandText:='insert into allfile(name,time,size,ip)'
// x +'values name,:time,:size,:ip)';
// Parameters.ParamByName('name').Value :=name;
// Parameters.ParamByName('time').Value :=time;
// Parameters.ParamByName('size').Value :=size;
// Parameters.ParamByName('ip').Value :=ip;
//execute
end;
end;
end;

finally
closefile(f);
end;
end;

AdoDataSet.UpdateBatch(arall);

嘿嘿，你的问题，我刚刚在前两天遇到，问题出在ADOConnection上。

普通情况非线程使用的时候，你启动AdoDataSet.open,不管AdoConnection.connected为真为假，都能自动变成真。
而在线程中好象不行，必须手动设置AdoConnection.connected=True;

希望你满意。

同意楼上，
