I am not sure what you are asking over here....
Mind putting it in simple english ?

 

by: danz67Posted on 2009-10-23 at 02:49:32ID: 25642733

I need e view in report detail detail record.

TAB_DDT

idddt-date-ecc,,,

TAB_DETTDDT

id-idddt

 

by: senadPosted on 2009-10-23 at 02:51:38ID: 25642744

Tables are separate entities and though they might have some fields in common inserting into one table does not automatically update the other.So if you do an insert in table2 the change will not be visible in Table1.
It all depends what you are inserting and what actually needs to be updated....If I follow you correctly....

 

by: senadPosted on 2009-10-23 at 02:59:13ID: 25642772



So for your report of the TAB_DDT table you drop 3 dbtext components on the report:
DbText1,DbText2,DbText3
In the report, link your dbtext to the right datasource and each dbtext to corresponding field.
dbtext go in the detail section of the report.

is this what you wanted ?

 

by: danz67Posted on 2009-10-23 at 03:12:37ID: 25642843

I have already created a report
MasterData = TAB_DDT
DetailData = TAB_DETTDDT
but I see all the records in TAB_DETTDDT per TAB_DDT, it seems wrong not you think?

 

by: senadPosted on 2009-10-23 at 03:25:36ID: 25642911

You are linking the tables to report.The fetching of the data for the report should be done wit a queery.

 

by: senadPosted on 2009-10-23 at 03:35:59ID: 25642967

so if you are using the grid you should use something like this for the queery:
(this is just cut&paste from somewhere in my program)

procedure TForm10.ADOQuery2AfterScroll(DataSet: TDataSet);
begin
with ADOQuery3 do
 begin
   Close;
   if ADOQuery2.FieldByName('UporabnikID').AsString <> '' then
   begin
   SQL.Text:= 'select * from Rfiliale where UporabnikID = ' +
       ADOQuery2.FieldByName('UporabnikID').AsString;
     Open;
   end;
 end;
end;

How?

 

by: senadPosted on 2009-10-23 at 03:49:14ID: 25643052

SELECT table1.column1, table2.column2 FROM table1, table2 WHERE table1.column1 = table2.column1;

use your immagination.... :-)

 

by: senadPosted on 2009-10-23 at 03:50:06ID: 25643054

WHERE table1.idddt = table2.idddt

Dear, I had already made this query but the problem remains, my question is how did I already said in the report is displaying wrong in fact in the report displays all the records in detail and not just those for the master

 

by: senadPosted on 2009-10-23 at 13:25:02ID: 25648212

can you post a picture ?

 

by: danz67Posted on 2009-10-23 at 22:50:29ID: 25650987

You can see the structure report and finally result on the view.
Details of the record appears the same for all master.

 

by: danz67Posted on 2009-10-23 at 22:52:53ID: 25650993

Sorry but the first report is wrong, this is the right one

 

by: senadPosted on 2009-10-24 at 14:04:05ID: 25654352

you queery is returning all the records but you want only specific ones.Right?
If so then you must modify the query to grab the specific records by date for example.
The way you are presenting records you can easily remove the masterdata1 band...


 

by: senadPosted on 2009-10-24 at 14:11:20ID: 25654384

To avoid duplicate data, you need to enable and disable your QRDBText
components by saving the data from the previous record and comparing it
to the current record. If it is the same then make the
component.enabled := False; Otherwise it is true. Use the Detail
band's Before Print event to put your code.

Here is an example:

1. Create a global variable(s) to hold your data from the previous
record. Be sure to initialize them in the QuickRep1.BeforePrint event.

2. In the Detail Band's before Print event add this kind of code:

procedure TForm6.DetailBand1BeforePrint(Sender: TQRCustomBand;
var PrintBand: Boolean);
begin
{Check Variable for duplicate data}
If CheckVar1 = Table1.FieldByName('Code').Value
then QRDBTextCode.Enabled := False
else QRDBTextCode.Enabled := True;

Table1.FieldByName('Code').Value := CheckVar1;
{Sets data up for next record check}

end;

Having said all that, with Proper grouping of data, into header records
and detail records, you should not see much need for this kind of code
if you place the duplicate data in the GroupHeader band.

Hope this is what you are looking for.
