能不能查询combobx是否有某个数据集
combobox1
a
b

表EMP
name

b
c
d



想实现 select name from EMP where name in combobox1.text


结果是
a
b




[解决办法]
什麼數據庫？自己循環combobox拼接成in('',''),這樣的格式就行了啊
[解决办法]
MSSQL:

Delphi(Pascal) code

s:=quotedstr(','+combobox1.Items.CommaText+',');ADOQuery1.SQL.Text:='select [name] from EMP where charindex('',''+name+'','', '+s+')>0';
[解决办法]
Procedure TForm1.BitBtn1Click(Sender: TObject);
Var
 I: Integer;
 S: String;
Begin
 With ADOQuery1, ComboBox1 Do
 Begin
   For I := 0 To Items.Count - 1 Do
   Begin
     If I = 0 Then
       S := QuotedStr(Items[I])
     Else
       S := S + ' , ' + QuotedStr(Items[I]);
   End;

   SQL.Clear;
   SQL.Add(Format('SELECT * FROM bbb WHERE NM IN (%s);', [S]));

   Application.MessageBox(Pchar(SQL.Text), 'sql', 64);

   Open;
 End;
End;
