edit a record with tdatabase - I am in trouble

[Silvio.Falconi]

I state I can not use an xbrowse to get the record so I have to search the archive first before to make the modify

I select an obtn where I save a cargo with many info

local cNumPre :=oBtn:cargo[28]

//open the database and order on Invoice number
oReserva:=Tdatabase():Open(,::cDbfPath + "Reserva" ,"DBFCDX", .t.)
oReserva:setOrder("res_pre" ) // field invoice ( string 16 cr)

nInvoice:= ALLTRIM(cNumPre) I havethis infor from oBtn:cargo

If oReserva:seek(nInvoice) //search

//here i must create the record
oPrenota:= :=oReserva:record() // it is sure I stay on the same record of the invoice ?

else
Msginfo("invoice not found")
return nil
Endif

I tried and allway return error not found

[Silvio.Falconi]

Sorry I not had the index on "res_pre"
discovered the mystery


a question

when i define the opening of the database i have

Code: Select all  Expand view

CLASS TReserva from TXData
   METHOD New()
ENDCLASS

METHOD New( lShared ) CLASS TReserva
   Default lShared := .t.
   ::super:Open(,::cDbfPath + "Reserva" ,"DBFCDX", lShared)
   if ::use()
      ::setOrder(1)
      ::gotop()
   endif
   RETURN Self

could i create another method for order search? example

METHOD SearchInvoice(nInvoice,oPre,oRes) CLASS TReserva
local oRes,lReturn:=.f.

oRes:setOrder(res_pre)
If oRes:seek(Invoice)
oPre:=:=oRes:record()
lreturn :=.t.
else
msginfo("error")
endif
return lreturn :=.t.


and from the program I could automatically recall the record through the method created?

oRes:=Treserva():New()

If oReserva:searchInvoice(nInvoice,oPre,oRes)

....

any suggestions please

Mr. Rao:

BTW, is there a class as TDataBase, but for MySQL?

Regards

[nageswaragunupudi]

Yes.
FWH has a built-in library for MySQL.
Can connect to MySql, open tables, and use them just like TDatabase.

Full documentation:
viewtopic.php?f=3&t=33286

If you are already using ADO for MySQL, you can use TRecSet class, which works similarly to TDatabase.

Mr. Rao:

Thank you, I Will try it.

Regards

[Silvio.Falconi]

thanks for the sample test but I must search a string on field Invoice this string is 13 Cr
before i couldn't find the data because i didn't order for the index i needed now it's ok

now I'm here asking you something else

once I have found the record in the Reserva.dbf file I have to load all the data I need for the reservation,
in particular I should also search for invoice in the oRigheInvoice archive which would be the lines of the invoice body,
and I have them different fields and for now I have done in the traditional method that is with do while / adddd () / endo

so I have to populate an array to put in the xbrowse as you can seeon this picture



in this array I have exactly 18 fields

my problem now is to save

i.e. for the reserva.dbf archive i.e. for the fields of the invoice header I have no problem,
instead I am afraid for the aData array that must be saved in the oRigheInvoice archive,
which for the first entry there is no problem for the modification I do not know how to do


Since I cannot pack I had thought of deleting the records that had invoice = nInvoice
and then inserting the new records but in doing so the archive becomes very large until the maintenance
operation by the administrator who can operate with archives in exclusive mode and will be able to pack the archive.



Or I have to come up with some other system that is what I saw on yunus.prg but I have not been able to implement it


in yunus' editinvoice function I saw that to load the records you do this

aItems := IIT->( FW_DbfToArray( cItemFlds, { || IIT->INVNUM == oRec:InvNum } ) )


I changed this line

static cItemFlds := "INVNUM,SERIAL,ITEMCODE,ITEMNAME,QUANTITY,UNIT,PRICE,DISCOUNT,RECNO()"

into

static cItemFlds := "ICO,TIPO,DESC,QTA,PREUNI,TOTQTA,DATAINI,DATAFIN,GIORNI,SCONTO,TOTALE,INVOICE,PRINTA4,PRINTPOS,STRUCTURE,BREVEDESC,PREZZOBASE,SERIAL,RECNO()"


how do i translate it into tdatabase?
I tried with
aData := oRigheInvoice:DbfToArray( cItemFlds, { || oRigheInvoice:Invoice == oRecPrenota:Invoice } )
but it not load any records
aData := oRigheInvoice:DbfToArray( cItemFlds, { || alltrim(oRigheInvoice:Invoice) == nInvoice } )
load all records from oRigheInvoice


then before save the array there is a part on source I not understood from this

WITH OBJECT oBrw

---

END


then I made the same from if lSave /endif but here make me error

[Silvio.Falconi]

Nages,
Now I found the solution
I can load to adata the records with

Code: Select all  Expand view

aData := oRigheInvoice:DbfToArray( cItemFlds, { || FIELD->Invoice ==alltrim(nInvoice) } )

if I delete a rows on xbrowse
then the procedure not delete the record on save

Code: Select all  Expand view

static cItemFlds := "ICO,TIPO,DESC,QTA,PREUNI,TOTQTA,DATAINI,DATAFIN,GIORNI,SCONTO,TOTALE,INVOICE,PRINTA4,PRINTPOS,STRUCTURE,BREVEDESC,PREZZOBASE,SERIAL,RECNO()"




            if ! Empty( oBrowse:aDeleted )
                   AEval( oBrowse:aDeleted, { |a| a[ 19 ] := -a[19 ] } )
                   oRigheInvoice:ArrayToDBF( cItemFlds, oBrowse:aDeleted )
                endif

 

I checked it , if I delete a row of browse I see on obrowse:adeleted the record

NOt save the SERIAL number and not save the invoice number

Code: Select all  Expand view

               AEval( aData, { |a| a[ 12 ] := oRecPrenota:Invoice } )  // invoice number
                AEval( aData, { |a,i| a[ 18 ] := i } )       // serial not run

if I take the same record, if I had deleted a line, I should have the invoice without that line and instead nothing has changed, having the same lines of the invoice I had before

How do I resolve?
