Hi, I have a strange message

Project FMRQ.exe raised exception class EDatabaseError with message MyQ_010030: Field 'TYPE' not found

when I run this code from the FMRQ.exe on the dmGest.MyQ_010030.open statement :

  if RgStage.ItemIndex = 0 then
    sStage := 'left join ' + Gestion + '.fmr1mac gmac on cma.perma = gmac.perma '
  else if RgStage.ItemIndex = 1 then
    sStage := 'left join cumul.fmr1mac cmac on cma.perma = cmac.perma ';

  if RgCourriel.ItemIndex = 0 then
    sCourriel := 'left join cumul.couriel ciel on cma.perma = ciel.PERMA ';

  if RgPointeur.ItemIndex = 0 then
    sPointeur := 'left join ' + Gestion + '.fmr1map gmap on cma.perma = gmap.perma ' ;

  if RgRemarque.ItemIndex = 0 then
    sRemarque := 'left join ' + Gestion + '.fmr1mar gmar on cma.perma = gmar.perma ' ;

  if RgCotis.ItemIndex = 0 then
    sCotisation := 'left join ' + Gestion + '.fmr1mab gmab on cma.perma = gmab.perma ' ;

  if RgImprimerQui.ItemIndex = 0 then
    sQui := 'where cma.perma = ''' + vPerma + ''''
  else
    sQui := 'where cma.perma in (Select perma from local.' + xUser + 'xselres) ';


  dmGest.MyQ_010030.SQL.Clear;
  dmGest.MyQ_010030.SQL.Text :=
    'select * from cumul.fmr1ma cma ' +
    sStage +
    sPointeur +
    sRemarque +
    'left join ' + Gestion + '.fmr1ma  gma  on cma.perma = gma.perma ' +
    sCotisation +
    sQui;

  dmGest.MyQ_010030.Open;

Code: Select all

// This is the code generated that run ok in MySql WorkBench
// This code also run in the MyQuery editor or when I click Active = True in the IDE
select * from cumul.fmr1ma cma 
left join gest2012.fmr1mac gmac on cma.perma = gmac.perma 
left join gest2012.fmr1map gmap on cma.perma = gmap.perma 
left join gest2012.fmr1mar gmar on cma.perma = gmar.perma 
left join gest2012.fmr1ma  gma  on cma.perma = gma.perma 
left join gest2012.fmr1mab gmab on cma.perma = gmab.perma 
where cma.perma = '1017391';

The field is there, everywhere in the table, in Workbench, in MyQuery editor, in fields editor but not when I run the application. I have remove the field from the field editor and I receive a message about the next field in the list 'Adresse'.
Is there a maximum number of fields ???
This query output around an hundred fields and 'TYPE' is around the 60.

Any idea welcome.

Hello.

MyDAC has no restriction on number of fields in dataset. (Such restriction is only in the MyDAC trial edition for 64-bit OSs - number of fields is limited to 6).

I couldn't reproduce the problem. Please provide the following information:
- the MyDAC version;
- the database version;
- scripts for creating all the tables involved in the query.

In addition, try deleting all fields from the Fields Editor and checking if the problem repeats.

Hi, here are the informations.

MyDac Pro 7.6.11 for RAD Studio XE
MySql 5.5.30-log
Windows 7
Hoops, I found my error. There is a line missing in the select of the .exe .
In the fields editor I have this select:

Code: Select all

select * from cumul.fmr1ma cma
left join cumul.couriel    ciel on cma.perma = ciel.PERMA <-- This line was missing in .exe
left join gest2012.fmr1mac gmac on cma.perma = gmac.perma
left join gest2012.fmr1map gmap on cma.perma = gmap.perma
left join gest2012.fmr1mar gmar on cma.perma = gmar.perma
left join gest2012.fmr1ma  gma  on cma.perma = gma.perma
left join gest2012.fmr1mab gmab on cma.perma = gmab.perma
where cma.perma = '1017391';

That is why I receive the message about a field missing.

Thanks to let me explain my error.
