各位大哥救命！关于数据库查询问题，5.1前得搞定呀。(100分)

帮我看一下，系统数据库连接成功了，但是我在操作时他说我语法错误，
我就不知道错那了，请各位帮忙
提示的错误信{Project Projectaa.exe.raised exception class EoleException.with message.[Microsoft]
[ODBC DBase Driver] syntax error.in FROM.Clause process stopped.Use Step or Run to continue.}
我的程序如下：
procedure TForm1.BitBtn1Click(Sender: TObject);
var together,key:string;
begin
table:=combobox1.text;
together:='';
combobox2.text:=combobox2.Items[combobox2.itemindex];
key:=combobox2.Text;
if edit1.Text=''
then
begin
showmessage('请输入字段值以便查询');
edit1.setfocus;
end
else
begin
ADoQuery1.close;
AdoQuery1.SQL.Clear;
AdoQuery1.Sql.Add('select * from ' +Table+ ' where ' + key +' like "%'+edit1.Text+'%"');

还有就是我用adoquery连接我自己的数据库时连接成功，但是在执行时却连不上了，是怎么一回
事呀，我用的是delphi自带的paradox 别名dbdemo，各位一定要帮小弟一把呀。要是有愿意帮小
弟的请多多联系qq:12316730　在些小弟有礼了！

你是执行那步动作时出的错误？

语法错误在FROM子句。
select DISTINCT *,A.name,A.size from '+Table+' T,animals A where ......
将表名用个别名代替看看，还有Distinct能不能作用所有字段，也不太记得了，我很少用
这个Distinct来做唯一查询。

他说语法错误后就跳到projectaa中的Application.Run;句上了呀，可我感觉这没错呀，这是怎
么回事呀

你最好单步跟踪一下你的sql.text，看看是否是符合你的要求

FORM的程；序如下：
program Projectaa;

uses
Forms,
Unitaa in 'Unitaa.pas' {Form1};

{$R *.RES}

begin
Application.Initialize;
Application.CreateForm(TForm1, Form1);
Application.Run;
end.

procedure TForm1.FormCreate(Sender: TObject);
var iCount,j:integer;
tables:Tstringlist;
begin
try
tables:=Tstringlist.create;
Adoconnection1.GetTableNames(tables,false);
for j:=0 to tables.count-1 do
combobox1.Items.add(tables.strings[j]);
finally
tables.free;
combobox1.itemindex:=0;
combobox1.Text:=combobox1.items[combobox1.itemindex];
table:=combobox1.text;
ADoQuery1.close;
ADoQuery1.sql.clear;
AdoQuery1.sql.add('select * from '+table);
AdoQuery1.open;
Groupbox1.caption:=table+'数据表内';
GroupBox2.caption:='根据企业名称查询'+table+'表:';
ADoDatasET1.Close;
AdoDataset1.CommandText:='';
ADoDataset1.commandText:='select * from '+Table;
AdoDataset1.open;
Combobox2.items.clear;
for icount:=0 to AdoDataSet1.Fields.count-1 do
begin
Combobox2.items.add(AdoDataset1.fields[icount].Fieldname);
end;

这里的人是不是瞧不起我们这些菜鸟呀，怎么不削这些问题呀，有点伤心呀，我的问题还是
没解决的呀，还忙哪位大哥能伸一只手来拉小弟一把呀，难倒真的要看我死在这儿吗？

你写了这么长的代码，你想累死偶门阿

我只是心急，主要是procedure TForm1.BitBtn2Click(Sender: TObject);和
procedure TForm1.BitBtn1Click(Sender: TObject);这两个里面的还望各位多多
帮忙了。小弟在此谢了。

是03年的五一吗？

to microming:
　　虽然我很笨，但也许你也不比我聪明多少呀，你不会看看我贴子上的时间吗，虽然已经过
去了，但是，我的问题还没解决的呀，所以还往大家继续帮我呀，虽然我现在还在，但是这个
程序我到现在还没有做出来，所以也就延误了交工期了。但最终还得解决的呀。请大家多多帮
忙了。
