Data Table wzmc
Field wzmc
Record 1: Steel
Record 2: Wood
Record 3: Coal
Record 4: Cement
How do I use all records of the wzmc field as the option of dbcombobox ??

Traverse the table and insert the dbcombobox drop-down list

With query1 do
Begin
Close;
SQL. Clear;
SQL. Add ('select wzmc from wzmc ');
Open;
First;
Dbcombobox1.items. Clear;
While not EOF do
Begin
Dbcombobox1.items. Add (query1.fieldbyname ('wzmc '). asstring );
Next;
End;

End;

Thank you !! I understand. But do I have to traverse the table and set the rows in the attribute?

No, it seems that BDE can be used. It's not necessary for a long time. You cannot be sure.

Then you need to use dblookupcombobox

Thank you !! I understand !!
